[0001] The present invention concerns a process for joining panels of fabric.
[0002] Conventionally, two panels of fabric are joined through a seam made near to respective
edges of the panels. Such edges are first placed over one another and are subsequently
sewn together through a thread which, passing from one side of the fabric to the other
of each panel, perfectly joins the panels to one another.
[0003] The main drawback of this sewing system is that it is not possible to separate the
panels unless the joining thread is cut completely. In such a way, if the two panels
of fabric overall define for example a clothing garment, it is not possible to easily
modify the size of the garment so as to take it in or out. Indeed, it is necessary
to completely take apart the part involved, separate the two panels of fabric and
sew them together again after having arranged the edges in the new desired position.
[0004] Hence, the purpose of the present invention is that of proposing a process for joining
panels of fabric that makes it possible to separate them without cutting the joining
thread and to couple them again in a different position in a simple and fast manner.
[0005] This and other purposes are reached with a process for joining panels of fabric,
the characteristics of which are defined in claim 1.
[0006] Particular embodiments are object of the dependent claims, the content of which should
be intended as an integral and integrating part of the present description.
[0007] Further characteristics and advantages of the invention shall become clearer from

[0008] Figure 1a indicates a first panel of fabric with reference numeral 1 which is folded,
in a central or lateral portion thereof, folding the fabric over itself so as to form
a Z obtaining in such a way a first fold 2a (or joining area) and a second fold 2b
(or intermediate area) suitable for being sewn as described hereafter. The second
fold 2b is thus placed over a lower edge or portion 1a of such a first panel 1, whereas
the first fold 2a is below an upper edge or portion 1b of the panel 1. At this point,
a channel seam is made as described in the rest of the description.
[0009] Alternatively, on the first panel 1 it is possible to carry out a plurality of folds
by simply repeating the folding steps described above. Figure 1b shows the panel 1
in which the upper edge 1b has been repeatedly folded folding the fabric over itself
so as to form a Z obtaining a plurality of first folds 2a', 2a",...2a
N and of second folds 2b', 2b", ..., 2b
N alongside one another.
[0010] Figure 1c shows a perspective view of a second variant of the first panel 1. In this
case the panel 1 comprises two distinct fabric portions, an upper portion 1' and a
lower portion 1", respectively, which are partially stacked over one another. Thereafter,
they are sewn together through an attachment seam 100 (or joining area) made so that
at least one part 102 of the upper portion 1' (which overlaps the lower portion 1")
remains free to lift with respect to the lower portion 1" and having an edge 104 (or
intermediate area) suitable for being sewn as described hereafter.
[0011] Clearly, it is possible to make a plurality of attachment seams on the first panel
so as to obtain processing similar to that deriving from the making of a plurality
of folds as described above.
[0012] In figure 2 a second panel of fabric, which is indicated with reference numeral 4,
is folded, in a central or lateral portion thereof, folding the fabric over itself
so as to form a Z obtaining in such a way a firs fold 6a (or joining area) and a second
fold 6b (or intermediate area) suitable for being sewn as described hereafter. The
second fold 6b is thus placed over a lower edge or portion 4a of such a second panel
4, whereas the first fold 6a is below an upper edge or portion 4b. At this point,
a channel seam is made as described hereafter. Subsequently, the lower edge 4a is
in turn folded, in particular rotated by 180° in the direction indicated by the arrow
A, so as to form a Z with the first fold 6a so as to obtain a third fold 6c.
[0013] The panels can be of any type of fabric, including leather.
[0014] The panels can be joined (as described in the rest of the description) vertically,
for example to take out or take in a clothing garment, or horizontally, for example
to lengthen a skirt or a curtain.
[0015] The panels 1, 4 have edges that can be rectilinear, curvilinear, broken etc. The
folds of the panels 1,4 (or the attachment seams 100 and the associated edges 104)
can be rectilinear or curvilinear, parallel to the edges of the panels themselves
or inclined with respect to such edges so as to form a predetermined angle.
[0016] For example, in the case in which the panels 1, 4 overall define a clothing garment
like a skirt or a pair of pants, the folds are rectilinear (or curvilinear), vertical
and parallel to the edges. In such a way, by carrying out a plurality of folds on
the first panel 1, it is possible to obtain a multi-sized clothing garment in which
each second fold 2b defines a different size in the moment in which the first panel
1 is coupled with the second panel 2.
[0017] In the case in which, on the other hand, the panels overall define a curtain element,
the folds may be inclined with respect to the edges of the panels. In such a way,
when the two panels are joined, curtains can be obtained in which the fabric widens,
forming some flounces, from top to bottom or
vice versa.
[0018] Finally in the case in which the panels 1,4 overall define a clothing garment like
a female sweater, the folds may be curvilinear so as to better follow the shape of
the breasts.
[0019] On each panel 1, 4 a seam is made, preferably with a sewing machine, as described
here.
[0020] In figure 3a the first panel 1 of figure 1a is shown in which, with a sewing machine
8 having a pressure foot 10, a seam 12 has partially been made (shown more in detail
in the rest of the description) by making a thread 14 pass through the fabric of the
second fold 2b so as to join, astride of the second fold 2b, the lower edge 1a and
the upper edge 1b. With the seam 12 the second fold 2b is thus fixed to the lower
edge 1a forming a channel 16 that runs along the entire panel 1 parallel to the first
fold 2a, said channel 16 being delimited on one side by the first fold 2a and on the
other side by the thread 14 of the seam 12.
[0021] Figure 3b shows the first panel 1 of figure 1c on which the complete channel seam
12 has been made that comprises a plurality of arcs shaped like a semi-circumference,
in particular sewing arcs 12a and continuity arcs 12b contiguous to one another. The
sewing arcs 12a are those that contribute to creating the channel 16 since they are
what join, astride of the edge 104, the first portion 1' to the second portion 1"
of the first panel 1. The channel 16 (shown with a broken line) runs along the entire
panel 1 parallel to the attachment seam 100 and it is delimited on one side by the
attachment seam 100 and on the other side by the channel seam 12.
[0022] The continuity arcs 12b are arranged exclusively on the second portion 1" of the
first panel 1, they do not per sé have a function in the joining process of panels
of the present invention and they are created since, using the sewing machine 8, it
is easier to make a complete seam without interrupting it in sections. Alternatively,
it is possible to make just the sewing arcs 12a and not the continuity arcs 12b, for
example if the channel seam 12 is made by hand or with a per sé known embroidery machine
that makes a knot at the end of every sewing arc 12.
[0023] Up to now we have described just the first panel 1 as made up of two portions of
fabric 1' and 1" joined together by an attachment seam 100, however, the second panel
4 could also be made in this way (as an alternative to the use of the folds above
described). The two panels 1 and 4, made with the two portions of fabric joined together
by the seam or with the folds, can be coupled together, to carry out the joining process
described hereafter, irrespective of the way in which they were obtained.
[0024] Figure 4 shows a schematic view of the second panel 4 on which, in an analogous way
as for the first panel 1, a channel seam 18 has been made using a thread 19. Such
a seam 18 joins, astride of the second fold 6b, the lower edge 4a and the upper edge
4b. In such a manner, the second fold 6b is fixed to the lower edge 4a forming a channel
20 that runs along the entire panel 4 parallel to the first fold 6a, said channel
20 being delimited on one side by the first fold 6a and on the other side by the thread
of the seam 18. The seam 18 comprises a plurality of arcs in the shape of a semi-circumference,
in particular sewing arcs 18a and continuity arcs 18b that are contiguous with one
another. The sewing arcs 18a are those that contribute towards creating the channel
20 since these are the ones that join, astride of the second fold 6b, the lower edge
4a and the upper edge 4b. The continuity arcs 18b are arranged exclusively on the
lower edge 4a, they do not
per se have a function in the process for joining panels according to the present invention
and they are created since it is easier to make a complete seam (continuity between
the arcs) without interrupting it in sections by using the sewing machine 8. Alternatively,
it is possible to make just the sewing arcs 18a and not the continuity arcs 18b, for
example if the channel seam 18 is made by hand or with a per sé known embroidery machine
that makes a knot at the end of every sewing arc 18 (the continuity between the arcs
is not necessary). As can be noted in figure 4, the lower edge 4a is folded, rotating
it by 180° in the direction indicated by the arrow B, forming the third fold 6c. The
lower edge 4a is folded so as to allow the second panel 4 to be arranged alongside
the first panel 1, as described in the rest of the description.
[0025] Figure 5 shows the second panel 4 in which the lower edge 4a has been rotated by
180° in the direction of the arrow B and, therefore, the sewing arcs 18a are visible.
[0026] Figure 6 shows a top view and a plurality of section views along the lines I, II,
and III of the first panel 1 of figure 1a. In this figure the complete seam 12 can
be seen, which comprises, as described above in reference to figure 3b, a plurality
of semi-circumference-shaped arcs, in particular sewing arcs 12a and continuity arcs
12b that are contiguous to one another. The sewing arcs 12a are those that contribute
towards creating the channel 16 since they are those that join, across the second
fold 2b, the lower edge 1a and the upper edge 1b. The continuity arcs 12b are exclusively
arranged on the lower edge 1a and do not have
per se a function in the process for joining panels according to the present invention.
[0027] The seams 12, 18 of the two panels 1, 4 can be made with different coloured thread
so as to create an ornamental element.
[0028] The sewing arcs 12a, 18a can have a shape that is different from a semi-circumference,
for example they can be shaped like a triangle or a rectangle. Moreover, each sewing
arc 12a, 18a can have a continuous linear profile (i.e. being formed by a plurality
of successive stitches so as to form a curved line) or a jagged profile (i.e. consisting
of a plurality of subsequent stitches so as to form a broken line) or a profile with
any other shape.
[0029] In the section view obtained along the line I a stitch of a sewing arc 12a is shown,
indicated by a wedge 22, which, in the moment in which the thread 14 is pulled so
as to arrange the lower edge 1a and the upper edge 1b alongside one another, closes
the channel 16.
[0030] In the section view obtained along the line II the stitch 22 is at the second fold
2a and therefore, it again closes the channel 16.
[0031] In the section view obtained along the line III such a stitch 22 is on the lower
edge 1a, therefore, when the thread 14 is pulled, it no longer closes the channel
16 that thus remains open.
[0032] Figure 7 shows a top view and a plurality of section views along the lines I, II,
and III of the second panel 4. In this figure the seam 18 can be seen formed by the
sewing arcs 18a and by the continuity arcs 18b.
[0033] In the section view obtained along the line I a stitch of a sewing arc 18a is shown,
indicated with a wedge 24, which, in the moment in which the thread 19 is pulled so
as to arrange the lower edge 4a and the upper edge 4b alongside one another, closes
the channel 20.
[0034] In the section view obtained along the line II the stitch 24 is at the second fold
6b therefore, it closes the channel 20 again.
[0035] In the section view obtained along the line III such a stitch 24 is on the lower
edge 4a therefore, when the thread 19 is pulled, it no longer closes the channel 20
that therefore remains open.
[0036] In the section views of figure 7 the lower panel 4a is indicated with a broken line
in the position that it takes up after having been rotated by 180° in the direction
of the arrow C.
[0037] In figure 8 the two panels 1, 4 are shown alongside one another so as to allow them
to be joined as described in the rest of the description. The lower edge 4a of the
second panel 4 is placed over the lower edge 1a of the first panel 1 (in this instance
that of figure 1a) so that the second 6b and third 6c fold of the second panel 4 are
arranged alongside the second fold 2b of the first panel 1.
[0038] In such a figure the seams 12, 18 are not shown so as to allow the panels 1, 4, alongside
one another to be seen more clearly; however, as described above, the seams are made
before being arranged alongside one another.
[0039] In the case in which on the first panel 1 a plurality of folds has been made, it
is possible to arrange the second 6b and third 6c fold of the second panel 4 alongside
each of the second folds 2b so as to join the two panels in different relative positions.
[0040] Preferably, the lower edge 1a of the first panel 1 is not folded (rotated by 180°)
whereas this occurs for the lower edge 4a of the second panel 4 to avoid the formation
of a slit between adjacent folds.
[0041] The folding of the lower edge 4a of the second panel is on the other hand carried
out so as to allow the folds to be placed alongside one another, since, otherwise,
the fabric of such a lower edge 4a would come into contact with the seam 12 of the
first panel 1 (not shown in this figure) which, as described above, is close to the
end of the second fold 2a of such a first panel 1. This would cause the fabric to
curl which, in addition to being ugly, would prevent the process for joining panels,
described in the rest of the description, from being carried out excellently. As an
alternative to the folding, it is possible to partially cut such a lower edge 4a so
that its end opposite the first fold 6a remains substantially aligned with the second
fold 6b (in such a case, the third fold 6c would no longer be present since the lower
edge 4a is no longer folded and therefore, in the moment in which the two panels 1,
4, are placed alongside one another, only the second fold 6b of the second panel 4
is arranged alongside the second fold 2b of the first panel 1). This solution would
not make it possible however, to make the continuity arcs 18b of the seam 18 since
there would not be enough fabric in the lower edge 4b and, therefore, it would be
necessary to make sections of seams with only the sewing arcs 18a.
[0042] In the case in which just the sewing arcs are made (by hand or with the embroidery
machine) the folds to be arranged alongside one another match up and it is not necessary
to fold the lower edge 4a of the second panel 4 rotating it by 180°.
[0043] Figure 9 shows a schematic perspective view of the panels 1, 4 of figure 8 each having
the respective seam 12, 18. In such a figure the sewing arcs 12a, 18a are shown defining
the respective channels 16 and 20.
[0044] Figure 10 shows a top view and a section view along the line I of the first panel
1 and of the second panel 4 alongside one another as shown in figures 8 and 9. The
lower edge 4a of the second panel 4 is placed over the lower edge 1a of the first
panel 1. In this figure only the sewing arcs 12a and 18a of the seams 12 and 18 can
be seen since the continuity arcs 12b and 18b are hidden below the upper edges 1b
and 4b.
[0045] In the section view obtained along the line I the two stitches are shown respectively
of a sewing arc 12a and 18a, indicated with the respective wedges 22 and 24, which,
at the moment in which the respective threads 14 and 19 are pulled, so as to bring
the lower edges 1a and 4a alongside the respective upper edges 1b and 4b, close the
channels 16 and 20.
[0046] Figure 11 shows a schematic perspective view of the panels 1, 4 arranged alongside
one another as described previously and joined together through a joining thread 30.
The joining thread 30 is threaded, preferably with the help of a needle 32, in an
alternate and progressive manner in subsequent sections of the channels 16 and 20
of each panel 1 and 4.
[0047] In the example illustrated in figure 11 the joining thread 30 is threaded in the
first section of the channel 16 starting at one end 36 of the panel 1, it is made
to pass along the side of the first sewing arc 12a, it is made to come out from the
section of channel 16 at an end portion 12a' of the arc 12a and is threaded into a
first section of the channel 20 of the second panel 4, following the first section
of the previous channel 16, at an initial portion 18a' of the arc 18a.
[0048] The process is repeated preferably for the entire length of the panels and, as it
goes on, each time the thread has been threaded in 3-4 successive sections of the
channels 16, 20 belonging, in an alternate manner, to the two channels 16 and 20,
the joining thread 30 is pulled so that it comes into contact with the sewing arcs
12a and 18a of the two panels bringing the ends 38 and 40 respectively of the second
fold 2b of the first panel 1 and of the second fold 6b of the second panel 4 in contact.
[0049] Alternatively, it is possible to repeat the process only for a portion of the length
of the panels.
[0050] Alternatively, it is possible to pull the joining thread 30 at the end of the joining
process, when the thread comes out from the last section of channel.
[0051] Subsequently, when the thread 30 has come out from the last channel 16 or 20 (in
the example illustrated in figure 11 such a channel is the channel 16 of the first
panel 1), the joining thread 30 is locked so as to prevent that, in the case in which
there is traction of the two panels in opposite directions, the joining thread 30
slides back into the channels 16 or 20 causing the panels 1 and 4 to separate.
[0052] In the case in which the sewing arcs 12a, 18a are shaped like semi-circumferences,
as illustrated in the examples described here, all the stitches of the arcs 12a, 18a
exert a resistance to the joining thread 30 which, when pulled, is in contact with
all of them. In the case in which the arcs have different shapes, for example triangular,
the thread in traction only acts upon the stitch at the vertex of the triangles making
the resistance exerted by the arcs less effective.
[0053] Advantageously, the joining thread 30 is locked by either inserting the thread in
an object such as for example a bead with a diameter that is greater than the width
of the channel from which the thread has come out, the channel 16 in this example
(so that the bead remains locked at the opening of such a channel 16), or by wrapping
the thread on a clip, for example a jewel or a button, fixed to the upper edge 1b
or 4b of one of the two panels 1, 4, or by threading the thread 30 back again into
the channels 16 and 20, for a length equal for example to 5% of the total length of
the panels, starting from the other channel with respect to that from which the thread
30 came out.
[0054] In a variant of the invention it is possible to insert decorative objects such as
beads on the joining thread 30. Such decorative objects are first threaded in the
joining thread 30, then they are made to pass inside the channels 16, 20 when the
joining thread 30 is threaded in such channels 16, 20 to join the panels 1, 4, and
are finally made to progressively come out from the channels 16, 20 at the points
in which the joining thread 30 passes from one section of a channel to a subsequent
section of the other channel, in such a way that in each of said points there is at
least a decorative object. In such a case, the decorative objects must have sizes
such as to be able to pass in the channels 16, 20. Alternatively, for example if the
decorative objects have dimensions that are greater than the width of the channels
16, 20, they can be threaded on the joining thread 30 progressively each time that
the joining thread 30 comes out from a section of channel to be threaded into the
next section of the other channel. For example, with reference to figure 11, when
the joining thread 30 comes out from the end portion 12a' of the arc 12a, at least
one decorative object is threaded on the joining thread 30 and then in turn the joining
thread 30 is threaded in the next section of the channel 20 at the initial portion
18a'.
[0055] In such a manner there will be at least one decorative object at each point for passing
from one channel to another and an ornamental effect will be obtained created by a
line (in the case in which the folds are rectilinear) or by a curve (in the case in
which the folds are curvilinear) of decorative objects.
[0056] The main advantage of the present invention is that two panels of fabric can be easily
separated and coupled by simply pulling out the joining thread 30 and threading it
back either in two different panels (for example with a different colour and pattern)
or in the same panels but in different channels corresponding to different folds.
[0057] With the process according to the invention it is thus possible to pack pieces of
clothing that can be adjusted in the anthropometric measurements or having different
fabric coupling. For example, in the case of a skirt, it is possible to combine a
fixed rear part with a variable front part, so as to transform the model using, smooth
fabrics, fabrics with folds, with flounces, with different colours or patterns for
the front part, as needed. In the case of a coat, it is possible to change the collar
or the cuffs, or to lengthen the coat itself, obtaining for example a jacket or an
overcoat.
[0058] Another advantage of the present invention is that the seam obtained with the process
illustrated above is slightly elastic and adapts to the movements of the person wearing
the clothes comprising such seams. In the case of a skirt, for example, it is possible
to create a garment that is close-fitting and figure-hugging, but which simultaneously,
"loosens" slightly at the seams when the person is sitting or bends over. This makes
it possible to obtain a better fitting of the garments.
[0059] Of course, without affecting the principle of the invention, the embodiments and
the manufacturing details can be widely varied with respect to what has been described
and illustrated purely as an example and not for limiting purposes, without for this
reason departing from the invention as defined by the attached claims.

18) each comprise a plurality of sewing arcs (12a, 18a) arranged to create the channels
(16, 20) joining, respectively astride of the intermediate area (2b; 104) of the first
panel (1) and of the intermediate area (6b) of the second panel (4), the lower portions
(1a; 1"; 4a) and the upper portions (1b; 1'; 4b) of said panels (1, 4).
7. Process according to claim 6, wherein the sewing arcs (12a, 18a) are in the shape
of a semi-circumference, or of triangles, or of rectangles.
8. Process according to claim 6 or 7, wherein the sewing arcs (12a, 18a) have a linear
profile that is continuous or jagged.
9. Process according to any one of the previous claims, wherein before arranging the
first panel (1) and the second panel (4) alongside one another, the lower edge (4a)
of the second panel (4) is folded, rotating it by 180°.
10. Process according to any one of the previous claims, wherein the intermediate areas
and the joining areas of the panels (1, 4) are rectilinear or curvilinear.
11. Process according to any one of the previous claims, wherein the panels (1, 4) have
respective edges and the folds of the panels (1, 4) are parallel to said edges or
inclined with respect to such edges so as to form a predetermined angle.
12. Process according to any one of the previous claims, finally comprising the operation
of locking the joining thread (30), so that, in the case in which the two panels (1,
4) are pulled in opposite directions, said joining thread (30) is prevented from running
back into the channels (16, 20) causing the panels (1, 4) to separate.
13. Process according to claim 12, wherein the joining thread (30) comes out from one
of said channels (16, 20), after passing through them, and is then locked by inserting
said thread (30) in an object with dimensions that are greater than the width of the
section of channel (16, 20) from which the thread (30) has come out, or by wrapping
the thread (30) on a clip fixed to the upper edge (1b, 4b) of one of the two panels
(1, 4) or by again threading back the thread (30) into the channels (16, 20), for
a predetermined length, starting from the channel opposite to that from which the
thread (30) has come out.
14. Process according to any of the preceding claims, wherein decorative objects are inserted
on the joining thread (30), said decorative objects being positioned at the points
in which the thread (30) passes from one section of one channel to another.
15. Process according to claim 14, wherein the decorative objects are first threaded into
the joining thread (30) then they are made to pass inside the channels (16, 20) when
the joining thread (30) is threaded in such channels (16, 20) to join the panels (1,
4), and are finally made to progressively come out from the channels (16, 20) at the
points in which the joining thread (30) passes through one section of one channel
to a subsequent section of the other channel, so that in each of said points there
is at least one decorative object.
