Field of the invention.
[0001] The present invention relates to the industrial production of fabrics, in particular
for making garments, lining of furniture, etc.
[0002] More precisely, the invention relates to the production of fabric cut portions with
an ornamental effect thereon and suitable for being sewn together forming such garments,
lining, etc.
Description of the prior art.
[0003] Many methods are known to make fabrics with ornamental and fancy patterns thereon,
obtained directly by weaving.
[0004] As well known, normally a fabric is made by a plurality of yarns arranged parallel
in a longitudinal direction, so called "warp", combined with one or more yarns woven
with the first in a transversal direction so called "weft". The result is a roll,
of the same width as the width of the loom, and length normally very long or continue
the same as the length of the warp yarns.
[0005] When weaving with many different colours yarns are used of various colour that are
woven in order to leave visible on the front side of the fabric only a portion of
colour corresponding to the desired pattern. This way on the fabric figures can be
made, isolated or repeated, according to that desired fancy pattern.
[0006] The industrial arrangements to carry out this method provides interfacing the loom
with a computerized control unit, which receives as input a file with the ornamental
pattern data and transmits weaving instructions to the loom, which makes the fabric
with that desired pattern.
[0007] In the production of garments or lining of furniture, moreover, a template is superimposed
on said roll that reproduces a model in order to cut a component of desired shape.
[0008] A limitation to this method is the difficulty to put in place in a repeatable way
the model on the roll with the same ornamental pattern exactly in the same position
for each garment of the same size.
[0009] Another limitation is the impossibility of reproducing a same figure on garments
of different size, using the same fabric, because the proportions between ornamental
pattern on the fabric and model do not coincide.
[0010] FR2782526 discloses a Jacquard weaving method where a number of structural figures are formed
to give a depth of color, and then a weaving program is constructed where the required
original motif is enlarged or reduced according to the required dimensions in the
fabric.
[0011] US5818720 discloses a computer-aided process of electronic designing and weaving fabrics with
individual pattern repeats across the width and length of the fabrics.
Summary of the invention
[0012] It is an object of the present invention to provide a method for making fabric cut
portions that allows to put in place in a repeatable way an ornamental pattern on
all the garments obtained with said cut portions of a same model and size.
[0013] Another object of the invention is to reproduce in a proportioned scale a same ornamental
pattern on garments with different size, in order to repeat a same ornamental effect
on each corresponding cut portion.
[0014] Further object of the invention is to allow a continuity of an ornamental pattern
when it is shared by adjacent parts to sew together.
[0015] Still another object of the invention is to allow a rational arrangement of the cut
portions on each roll of fabric, in order to assist the cutting operations and to
reduce the amount of fabric to use.
[0016] These and other objects are achieved by a method for making fabric cut portions with
an ornamental effect thereon comprising the steps of:
- creating, by a photo editing program, a mask comprising a background and a plurality
of geometric figures superimposed on said background, each geometric figure corresponding
to a fabric cut portion;
- pasting graphic elements on said mask in a predetermined way for each cut portion;
- creating an image file of said mask with said graphic elements pasted thereon;
- transforming said image file into a readable format file by the loom control system,
by means of a setting program;
- acquisition of said readable format file by the loom control system, said loom being
capable of weaving weft and/or warp yarns in at least two different colours;
- weaving said yarns by said loom under said readable format file obtaining a woven
fabric according to said background and said graphic elements contained in said geometric
figures.
[0017] Advantageously, said weft yarns are of a plurality of colours, and in particular
they are of basic colours as red, green, yellow, blue with white or raw/neutral and
black, and the warp yarns are of plain colour, selected from the group of raw/neutral,
black, white, or yellow/ochre.
[0018] Preferably, said graphic elements to paste on said mask are selected from the group
of pictures, drawings, computer graphics.
[0019] Preferably said mask has a plain background or a fancy background but in any case
visibly distinct from the colours of the figures present in the mask for clearly distinguishing
the contour of the parts to cut.
[0020] Advantageously, when said graphic elements are superimposed on said mask, they are
automatically trimmed not to fall outside the contours of said geometric figures that
are present in the mask and can be arranged in a predetermined position with respect
to the contours.
[0021] Advantageously, said method can be used to provide garments, furniture lining such
as sofa and armchair lining, and in any application where figures and ornamental pattern
are to be placed on a fabric with precision and repeatability as well as with customized
placements. ,
[0022] With the method according to the invention it is possible to make, on request of
an user, fancy patterns completely customized concerning colours, decorations and
graphic effects applicable to a desired product.
Brief description of the drawings.
[0023] The invention will be made clearer with the following description of an embodiment
thereof, exemplifying but not limitative, with reference to the attached drawings
wherein:
- figure 1 shows an example of fabric worked in different colours, as known in the art;
- figures 2 and 3 show respectively two cut portions of different size made on a same
type of roll, as known in the art;
- figure 4 shows an example of a mask ready for receiving graphic elements;
- figure 5 shows an example of an image file ready to be sent to the control unit of
a loom;
- figure 6 shows a flow-sheet that describes the succession of operations that describe
the method.
- figure 7 shows a roll comprising the parts making up the lining of an armchair.
Description of a preferred exemplary embodiment
[0024] Figure 1 shows an example of roll of fabric 1 executed with traditional methods,
with various ornamental and fancy patterns 4, obtained directly by weaving. The fabric
comprises a plurality of warp yarns 3 arranged parallel to one another in longitudinal
direction, of a plain colour selected from the group of raw/neutral, black, white
or yellow/ochre and many weft yarns 2, woven with the warp yarns in a transversal
direction, in a plurality of colours in particular red, green, yellow, blue with white
or raw/neutral and black.
[0025] In figures 2 and 3 two examples are shown of arrangement of models, respectively
9 and 10, on a same type of roll 1, for eventually cutting some parts making up a
pair of trousers. In particular in figure 2 a model is shown of larger size 9 and
in figure 3 a model is shown of smaller size 10. Obviously, being the models of different
size and using the same type of roll, it is impossible that the arrangement of graphic
elements is the same.
[0026] Figure 4 shows, according to the invention, an example of a mask 30 comprising a
background 20, and a plurality of geometric figures 11 superimposed on said background
20, each geometric figure corresponding to a fabric cut portion, said cut portions
being arranged in order to appear on the fabric in full scale.
[0027] Figure 5 represents an example of woven fabric 1, comprising the parts 10 making
up a pair of trousers; said parts are eventually cut following their respective contours.
The contours are definitely distinct from the background 20 and within them graphic
components 4 are pasted, which had been previously inserted in the mask in image file
format.
[0028] According to figures 4 and 5, the method according to the invention provides the
following steps:
- at first, by a photo editing program, the mask 30 of figure 4 is created comprising
a background 20 and a plurality of geometric figures 11, superimposed on said background,
each geometric figure corresponding to a fabric cut portion. Said cut portions are
arranged in order to be eventually reproduced on the fabric in full scale;
- then, as shown in figure 5 and 7, graphic elements 4 are chosen, to be reproduced
on the fabric, which are pasted in geometric figures 11 of the mask 30 in a predetermined
way for each cut portion;
- then an image file of said mask is made comprising said graphic elements, as shown
in figure 5;
- the image file, as fixed by a photo editing program, is acquired by the control system
of the loom, which is ready to execute the weaving steps of the weft yarns in a plurality
of colours and the warp yarns in plain colour, after that a set up program has made
it readable by the loom control system.
- then, finally, the weaving is effected under said readable format file obtaining a
woven fabric that has a background colour distinct from the colours of the geometric
figures and that contains geometric figures of the parts making up the product, reproducing
said images.
[0029] It is apparent that, in addition to an easy cut of the many components on the fabric,
owing to the clear difference between the neutral background and the contour of the
cut portions, the graphic elements are certainly centred on the component of fabric
cut portion, with high precision of the final product.
[0030] A flow-sheet that describes the succession of the operations of the method for making
fabric cut portions with an ornamental effect thereon is shown in figure 6. The operations
start with the creation of a mask comprising the contours of the parts of the product.
This mask is an image file obtained with a photo editing commercial program. Then,
the images to paste are chosen, taken from an image archive. The images chosen, then,
are pasted in the mask on desired parts of fabric. The resulting image file is saved
and translated into in a file of data that are sent to the loom. Then, the loom carries
out the weaving steps obtaining a fabric roll with portions ready to be cut having
thereon the chosen graphic elements arranged in the desired way.
[0031] Another application of the method for making fabric cut portions with an ornamental
effect thereon is shown in figure 7, illustrating a roll 1 comprising the parts 10
making up the lining of an armchair that are cut from the fabric following the contours
of such parts. The figure shows the graphic elements 4 that, as in the case of a pair
of trousers, have been obtained directly by means of weaving according to the present
method.

according to the conceptual point of view, so that others, by applying current knowledge,
will be able to modify and/or adapt for various applications such an embodiment without
further research and without parting from the invention as defined by the claims,
and it is therefore to be understood that such adaptations and modifications will
