[0001] The present invention relates to a combination of an introducer with a machine for
primary processing operations such as pressing, embossing, staking, finishing and
others, on tanned leather, fake leather, fabric, synthetic material and others, according
to claim 1.
[0002] In relation to the various methods with which they operate, machines for the primary
processing of tanned leather, fake leather, fabric, synthetic material and others,
commonly known with the generic definitions of "presses", "staking machines" and "pigment
machines", substantially consist of a station for introducing the material to be processed
followed by a station where the primary processing of the product occurs and by an
unloading station of the processed product.
[0003] Specifically, such machines are used:
- as "presses for drying/ pressing", when there is a need to make the upper surface
of the product to be processed soft and possibly also polished;
- as "embossing presses", when there is a need to emboss a pattern on the upper surface
of the product;
- as "staking machines", when there is a need to soften the product and/or give back
the softness lost during the preceding processing operations undergone by the above
product;
- as "pigment machines", when there is a need for a surface application of a liquid
pigment on the surface of the product.
[0004] Operatively, to obtain improved success of all these operations, there is a need
to subject the product to a thermal heat treatment which in addition to occurring
directly on the processing area, may occur also upstream thereof, when there is a
need for pre-heating the product to reduce the processing times and/or improve the
initial conditions of the processing.
[0005] By way of example, mention is made of the plate press described in patent document
WO 9210592 (fig.1), where the product to be processed (ref. L) is deposited on a first conveyor
belt (ref. TB) which, combined with a second conveyor belt (ref. HB), then positions
the aforesaid product in the three operating stations (references STS, TRS1, TRS2)
where opposed plates (ref. HZV) perform the operations, respectively, of drying and
where the heating of the product occurs with means inserted directly in the aforesaid
stations.
[0006] Again by way of example, mention is made of the plate press described in patent document
GB2038234 (figures 1, 2), where the leather (ref. CF) is positioned by means of a conveyor
belt (ref. 10) at a bridge structure (ref. 1), where a hydraulic press (ref. 7) provided
with opposed plates (references 3, 5) performs the embossing on said product and where,
in addition to the normal heating which occurs inside the bridge structure (ref. 1)
by means of the pressing plate (ref. 5), the product additionally undergoes also a
pre-heating by means of external devices (ref. 16) positioned upstream of said structure.
[0007] Again by way of example, mention is made of a roller press described in patent document
DE 20 2006 003489 U1 (fig. 2), where the leather (ref. 6), which is positioned on a conveyor belt (ref.
11), is caused to pass through a limited area (ref. 17) defined by two opposed rollers,
an upper roller, specifically an embossing pressure roller (ref. 18), and a lower
contrast roller (ref. 13), and where a pre-heating of the leather occurs by means
of a heating unit (ref. 20) arranged immediately upstream of the aforesaid rollers
and consisting of a radiator (ref. 22) which transfers the heat to the aforesaid leather
by means of a heated belt (ref. 21) before it is introduced into the aforesaid limited
area.
[0008] In particular, roller presses, known with the term "pigment machines", consist of
two opposed rollers which rotate in a synchronous and an asynchronous manner, the
upper roller being intended to transfer a liquid material onto the product to be processed,
while the lower one serving the function of dragging means; they may be provided with
an apparatus that serves as crease spreader and facilitates the introduction of the
product into the limited processing area.
[0009] In the current prior art, among the various types of apparatuses for introducing
the product which are positioned immediately upstream of the primary processing station
and are known with the generic term of "introducers", an apparatus is common which
consists of a pair of webs wound in a ring, mutually overlapping, so as to identify
an intermediate area where the product, while in sliding engagement, undergoes a flattening
and spreading effect before contact with the primary processing area.
[0010] By way of example, mention is made of patent document
EP 2177632 A1 (figures 1, 2), where the leather (ref. P) is conveyed into a limited processing
area (ref. K), defined by a knurled upper roller (ref. 2) and a lower rubber roller
(ref. 1), by means of the use of an introducer consisting of a pair of webs wound
in a ring (references TS, TI), mutually overlapping so as to identify an intermediate
area where the product, while in sliding engagement, undergoes a flattening and spreading
effect before contact with the aforesaid primary processing area; basically, it undergoes
an automatic "crease spreading" action.
[0011] Operatively, with the use of the introducer, which consists of an apparatus that
is positioned immediately upstream of the primary processing station, the leather
or another product to be processed does not require spreading out on a conveyor belt
since advantageously, said product is transferred directly by the introducer or "crease
spreader" to the "limited area" of the primary processing station where the processing
occurs, as is apparent from the comparison between figures 2 of patent documents
GB 2038234 and
DE 202006003489 U1 and fig. 2 of patent document
EP 2177632 A1.
[0012] In actual practice on the other hand, the absence of the conveyor belt in the station
for introducing the leather does not allow any pre-heating apparatuses of the leather
to be positioned [see positioning of said apparatuses in documents
GB 2038234 (fig. 2/ref. 16) and
DE 202006003489 U1 (fig. 2/ref. 20)], whereby there may only be a heating action which occurs only in
the primary processing station, at the heated plates or rollers. Such condition, in
actual practice, does not allow products to be processed such as tanned leathers,
which require being adequately heated to melt the chemical products applied on the
surface in the previous processing operations and simultaneously may not be subjected
to excessive heating in order not to compromise the quality and the softness of the
processed product.
[0013] To illustrate, in the presses where the heating is assigned only to the upper roller,
the heat exchange area occurs in the tangent contact line between the product and
the hot roller and the temperature of said roller is adjusted on a single value for
the whole length of the aforesaid hot roller/product contact line, with the consequence
that a concentrated heating action is caused on a single part of the product, the
one in contact with the aforesaid hot roller.
[0014] It is the object of the present invention to make a device to be applied on the above
primary machines such as "presses", "staking machines" and others, which does not
have the drawbacks manifested by similar products of known type.
[0015] Specifically, it is the object of the invention to make an introducer device which
increases the temperature and/or the moisture of the product to be processed in a
regulated manner.
[0016] It is a further object of the invention to make a device which facilitates the introduction
of the leather into the machine.
[0017] Such objects are obtained by providing the machine with an introducer which, in addition
to functions of flattening and crease spreading, provides also a pre-heating and possibly
also a moistening of the product to be processed, on one or both sides, in a regulated,
homogenous manner and at a temperature which is independent from the operating temperature
of the plates or of the rollers which operate in the primary processing area.
[0018] Practical tests have demonstrated that, with the pre-heating or moisturizing of the
product, pressing/embossing, staking and pigmentation effects may be obtained which
are significantly different and improved with respect to the ones obtained with traditional
machines.
[0019] In essence, since the leather or product being processed is already pre-heated when
introduced into the primary processing station, embossed leathers and other products
with increased performance and softness may be obtained due to the lower temperature
required by the plates or by the upper roller which perform the primary processing.
[0020] Since a greater contact surface with relatively low temperatures may be taken advantage
of in the presses, the total melting of the finishing chemical compounds is obtained
so as to obtain a leather with considerable physical features and appearance, for
example less shininess.
[0021] Finally, the invention provides for the introducer to be provided also with a hydraulic
circuit which performs a vaporization action to make the sliding product adequately
hydrated so that when said product enters the limited area to undergo the primary
processing, the loss of moisture undergone by the product itself is compensated for.
The invention will be better described by means of the description of a possible embodiment
thereof, provided by way of a non-limiting example, with the aid of the accompanying
drawings, where:
- fig. 1 depicts a diagrammatic view of the introducer of the invention, positioned
at a station for the primary processing;
- fig. 2 depicts a perspective view of the introducer of the invention.
[0022] As shown in fig. 1, positioned immediately upstream of the primary working station,
indicated as a whole with reference "PWC", consisting of, in the specific embodiment
depicted, an upper roller R1 heated with smooth or embossed surface, and of a lower
pressing roller R2, which define the limited primary processing area "K", is the introducer
of the invention, indicated as a whole with reference 100, serving the function of
introducer station "IS", which consists of a first device indicated with reference
10, which serves the function of introducer/crease spreader and is of the type formed
by a pair of webs wound in a ring 1 and 2, mutually overlapping, so as to identify
an intermediate area "Z" where the product "P", while in sliding engagement, undergoes
a flattening and spreading effect before the contact with the above dragging rollers;
said device 10 is characterized in that it provides for, inside each of the two webs
1 and 2, thermal apparatuses 3 and 4 that transmit the heat to the two portions of
the above webs and that define the channel for the passage of the product "P" which,
consequently, undergoes heating on both sides, thereby obtaining a pre-heating of
the product itself.
[0023] The introducer 100 is completed with the positioning, immediately upstream of the
device 10, of a second device 20 serving the function of transfer belt, on which the
operator deposits the product "P" to be processed.
[0024] Moreover, the introducer/crease spreader 100 provides for being equipped also with
a vaporisation circuit, for wetting both sides of the product "P", which supplies
spraying bars 5 and 6 arranged inside the two webs 1 and 2 for hydrating the product
"P", and spraying bars 7 and 8 positioned on the transfer belt 20 for pre-hydrating
the product itself, when required.
[0025] Operatively, the temperatures, the operating temperature of the upper heated roller
R1 where the pressing/embossing operations are realized and the pre-heating temperature
of the thermal apparatuses 3, 4 where the pre-heating of the product "P" takes place,
are adjusted independently of each other.
[0026] Again operatively, the steam flows that supply the first spraying bars 5, 6 for the
hydration and the second spraying bars 7, 8 for the pre-hydration, respectively, are
adjusted independently of each other; normally, the first spraying bars 5, 6 are used,
while the second spraying bars 7, 8 perform an auxiliary function because they are
activated only when the product "P" to be processed is considerably dehydrated. Finally,
the invention provides for the first device 10, serving the function of introducer/crease
spreader, and the second device 20, serving the function of transfer belt, to be mutually
connected in the joint point 30 and to form a single structure 100. With the constructional
solution described above, when it is provided simultaneously with the thermal apparatuses
3, 4 and with the spraying bars 5, 6, 7, 8, the introducer 100 may operate alternately
with function only of heating by activating only the thermal apparatuses 3, 4, or
with function only of hydration by activating only the spraying bars 5, 6, 7, 8 of
the product "P", and may perform alternately a regular hydration using only the first
front spraying bars 5, 6 or only a pre-hydration using only the second spraying bars
7, 8.
[0027] Overall, the introducer/crease spreader 100 of the invention performs the function
of introducer station "IS" and consists of an apparatus which is totally independent
and separate from the members of the machine operating in the primary working station
"PWC".
[0028] It is apparent from that above that the objects of the invention have been achieved
because the introducer of the invention achieves a pre-heating and vaporization of
water on the product before the processing thereof, consisting for example, of ennobling
tanned leathers or pressing fabrics, and may be installed on machines having various
conformation which are already on the market.
[0029] Obviously, in execution step, several variants of the introducer of the invention
are possible, and also the use of different technical components, according to the
heating mean used, such as diathermic oil, hot water, steam, electrical resistors,
and to the type of operating machine to be equipped, so long as it all falls within
the inventive concept defined by the following claims.
