Technical Field
[0001] This invention relates to an apparatus for packaging a product, in particular for
wrapping the product in a piece of suitable wrapping material.
[0002] The product to be packaged is preferably a food product, especially a pasty food
product such as processed cheese, a stock cube, butter, margarine and the like. The
product might, however also be a semi-liquid or a solid food product such as yoghurt
or a mature cheese, respectively.
Background Art
[0003] Packaging apparatus, in particular for pasty food products such as processed cheese
portions, are known in prior art.
[0004] One disadvantage of prior art apparatus for packaging pasty products is that some
parts of the apparatus are difficult to access, causing problems to personnel responsible
for sanitizing the apparatus and creating a real risk to the hygiene and healthiness
of the product being packaged.
[0005] Another disadvantageous aspect of prior art machines relates to their configuration
which does not allow operators to monitor all the parts of a machine simultaneously
and thus making it difficult take prompt action when required. That is because in
prior art machines of this kind, some working areas are hidden or screened from each
other.
[0006] WO2005/058701 discloses a packaging machine for triangular pieces of processed cheese to be collected
into circular packages, wherein, from a production strip for providing shell die-cut
portions, said die-cut portions are cutout by a shearing or cutting station directly
arranged above a rotary horizontal table supporting the die-cut portions for conveying
them to the following processing stations with label placing means being radially
placed at the rotary horizontal table or supports.
EP1094005 discloses an apparatus for packaging a food product, in particular a pasty food product
such as a processed cheese portion, a stock cube, butter, margarine and the like,
in a wrapper made from a blank of suitable shape which is folded to make the package
to receive the product and comprising, wherein the apparatus comprises means for feeding
a blank from which the wrapper is made, and wherein said blank is cut from a respective
web on which respective means apply the labels.
WO03/091043 discloses an apparatus for feeding elements for wrapping a pasty, liquid or semi-liquid
food product, in particular, processed cheese, comprising means for dispensing tear
strips, means for dispensing wrapper sheets and means for dispensing labels , and
means for assembling the wrapper elements consisting of a continuously revolving wheel
divided into zones for retaining the wrapper elements, wherein the label placing means
comprises a respective belt underneath the assembling means.
Disclosure of the Invention
[0007] It is provided a packaging apparatus, in particular for food products, especially
pasty food products such as processed choose, stock cubes, butter, margarine and the
like, to be wrapped preferably in a suitable wrapper, the apparatus comprising a mounting
frame, operating means for preparing the package and means for driving said operating
means, the apparatus being characterized in that the mounting frame comprises partition
means which extend lengthways along the apparatus, and from which the corresponding
operating means in turn extend and which separate the operating means from the drive
means.
[0008] Thus, the operating means which make the package are totally separate from the respective
drive means, with obvious advantages in terms of packaging hygiene and accessibility
to machine parts, since personnel responsible for operating the machine can easily
access the operating parts from one side of the machine, while the drive elements
are on the opposite side.
[0009] This also makes it easier and quicker to sanitize the apparatus.
[0010] Other advantageous aspects of the apparatus according to the invention are set out
in the other claims.

Description of the Preferred Embodiments of the Invention
[0012] The accompanying drawings show a preferred embodiment 10 of the packaging apparatus
according to the invention, in particular for packaging a food product.
[0013] The apparatus is especially suitable for packaging a pasty food product such as processed
cheese, stock cubes, butter, margarine and the like.
[0014] The apparatus might, however, also be suitably adapted for use in packaging other
products, be they semi-liquid, pasty, or solid, such as for example mature cheese
portions.
[0015] The apparatus according to the invention packages the product in a wrapper made from
a film, in particular a plastic film or a film in the form of aluminium foil. Preferably,
however, the wrapping film used is made from a foldable material, that is to say,
a material that keeps the folded shape imparted to it.
[0016] The wrapper comprises a sheet obtained from the film cut into a suitable shape and
folded in such a way as to enclose the product.
[0017] Besides the sheet of plastic film, aluminium foil or other material, the package
also comprises means, in the form of at least one plastic tape, for tearing and opening
the wrapper and a label if necessary. It will be understood, however, that the apparatus
according to the invention might also make packages without tearing and opening means
and/or without labels.
[0018] The finished package may be triangular, in the shape of the sector of a circle, quadrangular
or other desired shape.
[0019] In this description, the term "parts" of the wrapper in the plural form is used to
mean either the plurality of parts mentioned above, that is to say, the sheet, the
means for tearing and opening the wrapper and the label or only the sheet when the
apparatus is used to make wrappers comprised of the sheet only, or both the sheet
and the tear means, or both the sheet and the label, in the case of wrappers comprising
only two parts. Obviously, wrapper parts other than the ones specified here might
also be contemplated.
[0020] As illustrated, the apparatus 10 comprises a mounting frame 12 and operating means
for preparing the wrapper from the respective parts, as described in more detail below,
and which are driven by respective drive means, which are not illustrated in detail
in the accompanying drawings.
[0021] Advantageously, the mounting frame 12 defines partition means 120 which extend lengthways
along the apparatus, that is to say, in the direction in which the packages being
formed are fed and which mount operating means that are separated from the respecting
drive means by the partition means 120 themselves.
[0022] This means that the operating means which make the package are totally separate from
the respective drive means, with obvious advantages in terms of packaging hygiene
and accessibility to machine parts, since personnel responsible for operating the
machine can easily access the operating parts from one side of the machine, while
the drive elements are on the opposite side.
[0023] Thus, much time is saved because personnel attending to the apparatus do not need
to move from one place to another as they do with machinery made according to prior
art.
[0024] The apparatus is also very easy to clean, making its sanitization a quick and easy
task.
[0025] The partition means 120 are advantageously embodied as a flat longitudinal wall 120
that extends in a straight line in front of an operator standing beside the apparatus
and facing the operating means of the apparatus, as may be inferred from Figures 1,
2 and 4.
[0026] As illustrated, the frame 12 also comprises a transversal wall 121 upstream, a transversal
wall 122 downstream, and a covering top wall 123. Obviously, the apparatus may be
completed by walls and doors, preferably transparent, covering the operating area
where the packages are made.
[0027] Means 124, 125, 126 are also provided for supporting the frame on the floor, which
protrude transversally from the partition means 120 and which extend under the operating
means of the apparatus.
[0028] These means for support on the floor comprise a plurality of feet 124, 125, 126,
distributed lengthways, the feet 124 and 126 being located at the upstream and downstream
ends of the apparatus and the foot 125 substantially half way along the apparatus.
[0029] The wall 120 has respective holes made in it, not illustrated in detail in the drawings,
through which the operating means that make the packages are connected to the drive
means on the other side (not shown) of the longitudinal wall 120. Shafts or other
suitable transmission means for the respective drive elements extend through these
holes.
[0030] The apparatus according to the invention comprises means 14 for feeding the parts
used to make the wrapper.
[0031] More specifically, the feed means 14 assemble the parts of the wrapper, as will become
more evident in the rest of the description below.
[0032] Advantageously, the means 14 for feeding the wrapper parts extend transversally from
the partition means 120 and are rotatable about a horizontal or substantially horizontal
axis O.
[0033] Advantageously, these means for feeding the wrapper parts rotate in clockwise direction,
as indicated by the arrow W in Figure 1. Clockwise in this case refers to the direction
of rotation as viewed by an observer facing the partition wall 120 and looking at
the rotatable means 14.
[0034] It is thus possible to obtain a more convenient and advantageous layout of the devices
that dispense the parts of the wrapper.
[0035] According to present apparatus, the means 14 for feeding the wrapper parts move with
alternating motion, moving forward and stopping at the operating stations where the
wrapper parts are assembled.
[0036] The means 14 for feeding the wrapper parts comprise an outer surface having a shaped
profile that defines a plurality of circumferentially distributed sites 141 designed
to accommodate the wrapper parts, and in particular, to progressively accommodate
the parts of a single wrapper.
[0037] According to another aspect, the feed means 14 comprise a plurality of transversally
aligned sites which make it possible to advance a plurality of parallel rows of respective
wrapper parts. More specifically, each circumferential face of the roller-like means
for feeding and assembling the parts of the wrapper affords a first, a second, a third
and a fourth site, labelled 141 a, 141 b, 141 c and 141 d and transversally aligned
with each other.
[0038] The roller-like means 14 for feeding the wrapper parts thus comprise a revolving
member 142 having a plurality of flat faces 143 where the sites 141 for accommodating
the wrapper parts are made.
[0039] The flat faces 143 are wide surfaces circumferentially distributed and extending
in a direction perpendicular to respective radii extending from the axis of rotation
"O" of the roller means 142.
[0040] The wide flat faces 143 are separated from each other by shorter circumferential
sections 144.
[0041] As a whole, the faces 143 for accommodating the wrapper parts extend at right angles
to planes passing through the axis "O" and through the centre line of the respective
face 143 and make with the adjacent faces, or sites, 143 an orientation angle greater
than 135°.
[0042] In practice, the lateral surface of the roller 14 has a generally polygonal shape
with long sides and short sides, the sites for accommodating the parts of the wrapper
being made at the long sides. More specifically, the outer profile of the roller-like
member has a generally octagonal shape defining eight consecutive faces for accommodating
the parts of the wrapper.
[0043] In particular, the sites 141 for accommodating the parts of the wrapper comprise
a surface 145 for supporting the parts and means for retaining the parts on the supporting
surface 145. The retaining means are embodied as suction means comprising holes in
the area, or surface, 145 that supports the respective part, and conduits that put
the suction holes at each site selectively in communication with a vacuum source.
The suction holes and conduits are not illustrated in detail in the accompanying drawings.
[0044] As illustrated, the roller 14 for feeding the wrapper parts extends from the vertical
partition wall 120, said roller being driven by a respective axial shaft, not illustrated
in the drawings, which extends through a large hole made in an area upstream of the
partition wall 120.
[0045] The roller means 14 may be associated removably with the apparatus and there may
be a plurality or set of roller means to be used according to process requirements,
in particular according to the size of the package to be made.
[0046] Means 16 are advantageously provided for placing tear tape means on respective sites
141 of the means 14 for feeding the parts of the wrapper.
[0047] As illustrated in Figure 3, the tear tape means comprise a first tear tape 2 and
a second tear tape 3 which are suitably crossed over each other, as shown in Figure
3, in a manner well known to experts in the trade and therefore not explained in further
detail. Other tear tape configurations are also imaginable, however.
[0048] In particular, there are four means 161a, 161b, 161c, 161d for placing tear tapes
2 on respective transversally aligned sites on the feed roller 14.
[0049] As shown, the tear tape placing means 16 also comprise second means 162a, 162b, 162c,
162d for placing respective second tear tapes 3.
[0050] As illustrated, the means 16 for placing the tear tape means are advantageously mounted
under the means 14 for feeding the parts of the wrapper.
[0051] Further, as illustrated, the means for placing the second tear tapes 3 are mounted
downstream and, in particular, immediately downstream of the means that place the
first tapes 2 in the direction in which the wrapper parts are fed by said feed means.
[0052] Thus, while the first tear tape placing means place the four rows of first tear tapes
2 on respective downward facing sites of the feed means 14, the means for placing
four parallel rows of second tear tapes 3 operate on the adjacent sites, that is to
say, the sites on the part of the feed means 14 facing down and to one side.
[0053] It will be understood, however, that tear tape placing means which can place differently
shaped tear tapes in a different manner might also be used instead of the means described
here.
[0054] The means for placing the tear tapes 2, 3 are mounted on respective mounting means,
not illustrated in the drawings, which extend transversally in cantilever fashion
from the partition means 120.
[0055] As illustrated, each of the means for placing a respective tear tape comprises means
for mounting respective rolls of film from which the tear tape is obtained, means
for feeding the tear tape film and means for cutting the tear tape from the film,
which is preferably a plastic film. The means for feeding and cutting the tear tape
film are not illustrated in detail in the accompanying drawings.
[0056] Means for guiding the tear tape placing means may be provided to enable the placing
means themselves to be pulled out and, if necessary, lifted in order to change the
tear tape film roll.
[0057] Means 18 are also advantageously provided for placing the sheet constituting the
main body of the wrapper on a respective site of the means 14 for feeding the parts
of the wrapper.
[0058] In particular, the sheet is placed over the first and second tear tapes 2 and 3,
as illustrated in Figure 3, where the sheet is denoted by the reference numeral 4.
[0059] More specifically, the means for placing the sheet 4 are designed to place four parallel
rows of sheets on transversally aligned sites on the feed roller 14.
[0060] As illustrated, the means 18 for placing the sheet 4 on the wrapper part feed means
are mounted downstream of the tear tape placing means 16 in the direction in which
the wrapper parts are fed by the feed means 14.
[0061] In particular, the sheet placing means 18 extend beside the feed means 14 and are
designed to place the sheets 4 on respective transversally aligned sites 141a, 141b,
141c, 141d on the part of the feed means 14 facing up and to one side.
[0062] In practice, between the means that place the second tear tapes 3 and the means that
place the sheets 4, there is an empty station, corresponding to the sites on the vertically
positioned face of the lateral surface of the roller 14, there being cutting means
mounted alongside the vertically positioned sites for cutting the wrapper sheets 4
from the film 1, as described in more detail below.
[0063] The means for placing the sheets comprise means for feeding the film 1 and means
for cutting the film. The means for cutting and feeding the wrapper sheet film 1 are
not illustrated in detail in the accompanying drawings.
[0064] The means 18 for placing the sheets 4 on the feed means 14 also comprise means for
gripping the cut sheets 4 and means for guiding said gripper means.
[0065] The sheet 4 gripper means, not illustrated in detail in the accompanying drawings,
are guided by respective guide devices or means 182, comprising rails 182a, 182b,
182c, 182d for respective sheet 4 gripper means.
[0066] These straight rails 182a, 182b, 182c, 182d extend in divergent directions starting
from the position where the sheet is picked up to the position where the sheet is
delivered to the respective site on the feed means 14. As illustrated, the ends of
the longitudinal guide rails 182a, 182b, 182c, 182d are mounted on respective crossbars
182e, 182f.
[0067] The guide means 182, which are not illustrated in detail in the drawings, are removably
associated with the apparatus and extend transversally in cantilever fashion from
the partition wall 120.
[0068] It is contemplated the provision of a plurality, or set, of devices, or means, 182
for guiding the sheet gripper means, comprising different rails 182a, 182b, 182c,
182d, having substantially the same length for a suitable longitudinal stroke of the
sheet gripper means and a different angle of relative divergence in order to allow
guiding of gripper means for different package sizes, that is to say, to allow the
sheets to be placed in different transversal positions according to the size of the
sheet and package being made.
[0069] In other terms, for each different sheet size, the guide means or devices have guide
rails 182a, 182b, 182c, 182d whose respective ends 182'a, 182'b, 182'c, 182'd in the
area where the sheets are picked up are at substantially the same transversal distance
d'a, d'b, d'c from each other but whose ends 182"a, 182"b, 182"c, 182"d in the area
where the sheets are dispensed are at different transversal distances d"a, d"b, d"c
from one guide device to another, as may be inferred from Figure 4.
[0070] This greatly facilitates changeover from one size to another. It is sufficient to
substitute the guide means 182 with other guide means suitable for another size. Thus,
complicated and time-consuming changeover adjustments are minimized and made simpler
than in prior art machines.
[0071] In particular, in addition to the guide means, the means for gripping and cutting
the sheets must also be changed since they are mounted directly on the guide means.
[0072] The invention also contemplates the provision of advantageous means 20 for joining
the sheet 4 to the tear tapes 2 and 3. These joining means are embodied as respective
sealing means that extend transversally in cantilever fashion from the partition wall
120 and are located at a position corresponding to and facing the upward facing sites
on the horizontally positioned face 141 of the lateral surface of the means 14 that
feed the wrapper parts.
[0073] The sealing means 20 move downwards to join the heat-sealable face of the sheet 4
to the tear tapes 2 and 3 and up again to a position where the feed means can turn
freely.
[0074] The sealing means 20 are mounted downstream and, in particular, immediately downstream
of the sheet 4 placing means 18 in the direction in which the feed means 14 advance.
[0075] Positioning the sealing plate 20 above the roller means 14 for feeding the wrapper
parts enables the label magazines to extend over the sealing means 20, as explained
in more detail below.
[0076] The sealing means 20 are located on the side of the feed means 14 opposite the side
where the tear tape placing means are located.
[0077] The apparatus also advantageously comprises means 22 for placing a label, denoted
by the reference numeral 5 in Figure 3, on a respective site on the wrapper part feed
means 14, and in particular, in such a way as to place the label 5 over the respective
sheet 4.
[0078] Further, as illustrated in Figure 5, the label placing means 22 are mounted above
the wrapper part feed means 14 and downstream and, in particular, immediately downstream
of the sealing means 20 and of the sheet 4 placing means, in the direction in which
the wrapper parts are fed by said feed means 14.
[0079] The means 22 for placing a label on the respective sheet are also mounted on respective
mounting means which extend transversally in cantilever fashion from the partition
wall 120.
[0080] The label placing means comprise label accommodating means 122 in the form of a plurality
of magazines 122a, 122b, 122c, 122d, extending in a straight line at an angle to the
vertical and above the sealing means 20, as mentioned previously.
[0081] In practice, the placing means 22 place four labels on respective wrapper sites 141a,
141b, 141c, 141d.
[0082] The label placing means 22 comprise means 121 which pick up the label 5 from the
accommodating means 122 and transfer it to the feed means 14, and which are in the
form of corresponding revolving means that turn in the same direction as the wrapper
part feed means 14.
[0083] The label placing means also comprise means 123 for dispensing an adhesive material
to the labels 5 held by the label pickup and transfer means 121.
[0084] The label placing means thus comprise a revolving roller extending transversally
from the wall 120 and having a plurality of transversally aligned sites - in particular,
four transversally aligned sites - there being, for each single label fed by the means
121, four operating positions, namely, a position where the label is picked up from
the magazine, a position where adhesive is applied to it, an idle position and, lastly,
a position where the label is transferred to the means 14 that feed all the wrapper
parts. These operating positions correspond to 90° angular movements of the label
roller.
[0085] In particular, the label roller has an outer surface with sites on it for accommodating
the labels and comprising a surface on which the labels are supported and means for
retaining the labels on the supporting surface. These retaining means are, in particular,
embodied as suction means comprising holes in the area, or surface that supports the
label, and conduits that put the suction holes at each site selectively in communication
with a vacuum source. The suction holes and conduits are not illustrated in detail
in the accompanying drawings.
[0086] In practice, the labels are placed on respective sites on the part of the wrapper
feed means 14 facing up and to one side of the feed means 14, in particular, facing
the downstream section of the machine 10.
[0087] The label placing means 22 are located on the side of the feed means 14 opposite
the side where the tear tape placing means 16 are located.
[0088] Means are also advantageously provided for creasing the respective sheets 4 at a
respective site 141 of the means 14 for feeding the parts of the wrapper.
[0089] The creases 6, shown in Figure 3, are made in the sheet 4 in order to facilitate
its subsequent folding into a shape suitable for receiving the product.
[0090] In the apparatus according to the invention, the creases 6 on the sheet are advantageously
made when the latter is on the revolving feed means 14. This greatly simplifies the
structure compared to prior art machines.
[0091] Also advantageously, the sheet creasing means, operating at 24 and not specifically
illustrated in the accompanying drawings, are positioned alongside the wrapper part
feed means 14 on the side of the latter opposite the side where the sheet 4 placing
means are located.
[0092] In practice, the means for making at least one crease 6 on the sheets operate on
the vertically oriented sites facing the downstream section of the machine:
[0093] Advantageously, the means for making a crease 6 on the sheet 4 are mounted, relative
to the direction in which the wrapper parts are fed by said feed means 14, downstream
and, in particular, immediately downstream of the label placing means 22 and also
downstream of the means 18 that place the sheet 4 on the feed means 14.
[0094] Advantageously, the sheet creasing means also comprise four transversally aligned
operating elements extending transversally in cantilever fashion from the partition
means 120.
[0095] The wrapper creasing means, operating at 24, are located on the side of the feed
means 14 opposite the side where the sheet placing means 18 are located.
[0096] According to another advantageous aspect, means 26 are provided for picking up the
wrapper from a respective site on the wrapper part feed means 14.
[0097] These wrapper pickup means 26 are positioned alongside the wrapper part feed means
and are designed to pick up the wrapper from the sites on the part of the feed means
14 facing down and to one side, that is to say, those facing the downstream section
of the machine.
[0098] The wrapper pickup means 26 are located on the side of the feed means 14 opposite
the side where the sheet placing means are located.
[0099] Advantageously, the wrapper pickup means are located immediately downstream of the
creasing means 24 in the direction in which the wrapper parts are fed by the feed
means 14.
[0100] The wrapper pick up means take the form of a rocker element 26, which is pivoted
in line with the roller 24a that advances the means for feeding the wrapper in the
containing condition, that is to say, when the wrapper has been folded into a cup-shaped
shape, as may be inferred from Figure 5, and are designed to hold the wrappers at
the top or engaging the top faces of the sheets after receiving them from first means,
not illustrated in detail in the accompanying drawings, for picking up the sheets
directly from the assembly roller and which hold them at the bottom or engage the
bottom faces of the sheets.
[0101] The assembled wrappers 4 are thus delivered by the rocker elements 26 to downstream
means for forming the wrapper, said sheets being applied or rested on a horizontal,
or substantially horizontal surface of the forming means, also illustrated in Figure
6.
[0102] Upstream of the wrapper part feed means 14 means are provided for feeding the film
1 from which the wrappers are made.
[0103] Advantageously, these film 1 feed means, labelled 30 in the drawings, extend transversally
from the frame partition means 120.
[0104] In practice, the film feed means comprise a transversal shaft 30 that mounts a roll
31 into which the transversal shaft 30 extends from the longitudinal wall 120 from
which the other operating means of the apparatus also extend, in particular, the assembly
means 14 and the related means for placing the parts of the wrapper.
[0105] Thus, the operator has all the operating parts of the machine in front of him/her
and can easily supervise operations and take prompt action when necessary, for example
when the roll 31 needs to be changed.
[0106] Advantageously, the level at which the film feed means 30 extend above the supporting
surface of the apparatus 10 is lower than the level occupied by the means 14 that
feed the wrapper parts.
[0107] Advantageously, the film feed means 30 rotate in clockwise direction and comprise
respective transmission means 32 positioned above the shaft 30 and designed to make
the film 1 unwound from the roll 31 follow a vertical or substantially vertical path.
The transmission means are embodied as rollers 32 located between the roll mounting
shaft 30 and the wrapper part feed means 14.
[0108] As illustrated, the sheet 4 placing means 18, which are mounted on the side facing
the end upstream of the assembly means 14, are also located between the latter and
the wrapper sheet web feed area.
[0109] Means are also advantageously provided for shaping the wrapper, said means being
designed to form a cup-shaped container suitable for receiving the product portion.
[0110] The wrapper shaping means comprise forming means 40 and means 42 for pushing the
wrapper into the forming means 40.
[0111] More specifically, the shaping means comprise hoppers 40 having a vertical, or axial,
open-ended cavity of suitable size and designed to give the wrapper a cup-shaped shape,
each of these hoppers being of a type well known to experts in the trade.
[0112] The shaping means 40 are mounted on respective mounting means which extend transversally
in cantilever fashion from the partition means 120.
[0113] The means 42 that push the flat sheets into the hoppers - there being four hoppers
aligned with each other and fixedly connected to the partition wall 120 - in turn
comprise respective pistons 42 that move vertically between a raised position that
enables the still flat sheets to be placed in position above the hoppers, and a lowered
position in which the pistons extend downwardly past the bottoms of the shaping hoppers.
[0114] This pushing movement of the pistons gives the wrapper sheets a cupped shape and
causes them to be placed on respective means, labelled 44 in their entirety in the
drawings, which feed the cup-shaped wrappers lengthways and which extend under the
hoppers 40.
[0115] The pushing means 42 are also mounted on respective mounting means which extend transversally
in cantilever fashion from the partition means 120, in a position above the hoppers
40.
[0116] As just mentioned, means 44 are provided for feeding the cup-shaped wrappers lengthways.
[0117] The means for feeding the cup-shaped wrappers lengthways comprise supporting means,
or pockets, 46 - four parallel rows of transversally aligned pockets being provided
- mounted on respective belt means 48, in particular comprising a first and a second
lateral belt 48a and 48b, forming an endless belt of pockets 46 driven by respective
wheels 46a, 46b which are in turn driven and supported by shafts protruding from the
transversal wall 120.
[0118] The belts 48a, 48b mount transversal blocks that support a plurality of pockets 46,

[0132] Means 56 are also provided for sealing the retaining tabs to the cap under them.
[0133] The means for sealing the retaining tabs to the cap are mounted on respective mounting
means which extend transversally in cantilever fashion from the partition means 120.
[0134] In particular, the means 56 for sealing the retaining tabs to the cap can be moved
between a lowered position and a second position. More specifically, the means for
sealing the retaining tabs to the cap can be moved between a lowered working position,
that is to say, the position where they seal the tabs to the cap, and a raised position
where the respective sealing plates 156' can be cleaned.
[0135] The means for mounting the sealing plate 156' comprise a fixed part 156 and a part
157 that is mobile relative to the fixed part 156. In particular, the mobile part
157 extends transversally of the apparatus and swings from the fixed part on pivoting
means 156a at the longitudinal partition wall 120.
[0136] Means 147 are provided for positioning the cup-shaped, filled wrapper at a height
such that the top of the product is at a predetermined, desired height.
[0137] The means 147 for positioning the wrapper in height are embodied as longitudinal
guide means 147 located at the wrapper feed means 44.
[0138] The guide means 147 for lifting the cup-shaped wrapper are located at the wrapper
feed means 44.
[0139] As illustrated, the wrapper holding means 46 comprise, for supporting the bottom
of the wrapper, a base 146a having an extension 146b that protrudes downwardly through
a respective conduit 46' under the fixed part of the wrapper holding means or blocks
46, said downwardly protruding extension 146b having a bottom contact end 146'b that
runs in the guide means 147.
[0140] By sliding in the guide means, the height of the wrapper can be suitably adjusted
to fold the cap retaining tabs in such a way as to obtain a "sharp" edge or a "soft"
edge, that is to say a straight edge or a more rounded edge, according to packaging
requirements.
[0141] The means 147 for positioning the wrapper in height are removably connected to the
apparatus and, more specifically, the invention contemplates the provision of a plurality
of means 147 for positioning the wrapper in height, selectable according to requirements.
[0142] The removable connecting means consist of screws and brackets labelled 148 and 149
in Figure 6.
[0143] In particular, the guide means 147 are embodied as respective longitudinal bars with
suitably shaped top ends 147a. More specifically, there are four transversally aligned
bars for driving the mobile bases or means 146a that lift the wrapper being formed.
[0144] The mounting means of the height positioning means 147 also extend transversally
of the partition wall 120.
[0145] Downstream of the cap sealing means, in an area labelled 58 in Figure 1, respective
means may be provided for grouping the packages.
[0146] The invention described above is susceptible of industrial application and may be
modified and adapted in several ways without thereby departing from the scope of the
inventive concept. Moreover, all the details of the invention may be substituted by
