ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a label made by the woven fabric technique and a method of making the label, the label being provided with non-folded cut longitudinal sides and with foldable cut narrow sides running transversely to the longitudinal sides. The labels have a backing fabric formed from at least two warp threads and one ground weft thread and having a plurality of embroidery weft threads of fusible thread material forming a figure.
2. Description of the Prior Art
As is known the labels are woven in the form of bands in a broad fabric composed of fusible yarns, a repeat being provided for each band. The broad fabric consists of a backing fabric consisting of warp threads, a ground weft and of embroidery wefts which are led over the entire web breadth and which form a figure of the label. The bands are subsequently cut out of the textile web in the form of strips running in the warp direction on their longitudinal side, the backing fabric and the embroidery wefts being severed. If a thermal cutting device is used for this purpose, the fusion of the backing fabric and of the embroidery weft threads gives rise to the known hard and rough fusion edges which are very thick and unpleasant.
FIG. 1
shows a version of a label known from WO 9302246. The label has, as is customary, a quadrangular shape with longitudinal sides
1
and narrow sides
2
. The label consists of the backing fabric
3
and embroidery wefts which, in one region of the label, produce a figure such that there is in each case an edge of backing fabric on the narrow sides. The label is woven in such a way that the warp threads
4
run parallel and the weft threads
5
transversely to the longitudinal sides
1
of the label. The longitudinal sides of the label are cut by a thermal cutting device. The backing fabric and the embroidery wefts are thereby fused together, so that the disturbing fusion edge
6
is formed. The label according to
FIG. 1
is folded on the narrow sides (only one fold illustrated), so that the fusion edge
6
is free. In this prior art, to avoid the undesirable fusion edges, the fusion edge is machined by a pressing and/or vibrating tool for non-cutting shaping, this being labor-intensive, but still not affording the desired effect.
The same problem is also addressed in EP-A-0 389 793, in which it is referred to as useless to experiment at the fusion edges (column 1, lines 42 to 54). Instead, a complicated method is postulated, whereby the labels are produced in a two-stage method. In a first method stage, a semi-finished product with a cut longitudinal side and with greater breadth is produced. In a second method stage, the semi-finished product is folded at the margin to the final breadth and bonded adhesively on the rear side. Such a label is illustrated in FIG.
2
and is folded on the longitudinal sides in order to cover the fusion edge
6
. This label may also be provided with end folds
7
. The label is fastened on the narrow sides, so that the longitudinal sides
1
come into contact with the skin and an article of clothing. This side should have as soft an edge as possible, so that the article of clothing feels pleasant to wear and in order to avoid damage to the article of clothing and places on the human body where friction occurs. In order to achieve this, it is proposed, in EP-A-0 389 793, to provide a fold on the label in each case on the free longitudinal sides having the fusion edge and on the narrow side.
Apart from the complicated and costly production, it is also considered a disadvantage that the warp threads of the backing fabric run in the longitudinal direction of the label and the number of these is fixed, so that labels can be produced only in a specific quality, and that, for folding, the label has to be woven as a semi-finished product with larger dimensions. The folding of the longitudinal side having the fusion edge formed by the fused ground wefts and embroidery wefts leads to very thick and uncomfortable margins on the labels. If, in addition, an end fold is provided, the label consists of four layers in this region, and this is unacceptable to the user and the wearer.
If, as described in EP-A-0 546 485, the textile web is severed by means of a mechanical cutting device and a number of longitudinal threads are removed at the separating point by mechanical means, a fringed edge is formed on the longitudinal side of the label. It is considered a disadvantage that a margin consisting of backing fabric must likewise be provided in order to form the fringed edge, so that, for folding, the label has to be woven as a semi-finished product with larger dimensions and a special outlay is necessary in order to form the fringed edge. In addition to the complicated production method, another disadvantage is that further longitudinal threads may come loose at the fringed edge, so that the label becomes useless or unsightly.
The known method for the production of labels have the disadvantages that the folding of the longitudinal side necessitates a higher outlay in terms of adhesive bonding, and that, because of the dimensions of the semi-finished product, the weaving breadth of the weaving machine is utilized to only a restricted extent or there is a relatively large amount of waste.
SUMMARY OF THE INVENTION
The invention is intended to remedy this. The object on which the invention is based is to improve a label.
This object is achieved, according to the invention, by means of a label having two first non-foldable sides and two second foldable sides running transversely to the foldable sides. The label is made by the woven-fabric technique, with at least two warp threads and a ground weft thread for the backing fabric and also with a plurality of embroidery weft threads for making a figure. The embroidery thread is provided of fusible thread material. The embroidery wefts form the figure which runs parallel to and at a distance from the first non-folded sides of the backing fabric, and the non-folded sides are formed by cutting, outside the region of the figure, in the backing fabric.
It was found, surprisingly, that, by the longitudinal side being arranged transversely to the warp threads and by the embroidery weft threads being arranged at a distance from the longitudinal sides, and with production being carried out in the simplest possible way, the cut edge on the non-folded longitudinal side of the label is soft and skin-friendly and wearing comfort is improved appreciably because the cut edge produced by the ground wefts has virtually no brows. The cut edges can be covered by the narrow side being folded, with the result that the label is further improved. Since the weft threads run parallel to the longitudinal side of the label, a uniform appearance is achieved over the entire length of the label, because the weft threads cover the rear side uniformly.
A method for the production of labels is characterized, according to the invention, wherein a broad fabric is produced with fusible thread material by the woven-fabric technique with at least two warp threads and with a ground weft for the backing fabric, and also with a plurality of embroidery wefts for providing a figure. The broad fabric is separated after weaving by cutting the broad fabric into a set of strips lying next to one another. The broad fabric is woven in such a way that a plurality of labels lie next to one another with their first non-folded side in the weft direction and with their second foldable side in the warp direction. The broad fabric is cut along the second side in order to produce strips with transversely lying labels succeeding one another in the direction of run of the broad fabric.
The further advantages which can be achieved by means of the method according to the invention are to be seen in that labels of different length and breadth are woven on the same type of weaving machines. Labels with a weave repeat can be woven up to a weaving breadth of about 115 cm, so that only a small amount of waste occurs. The weft density in the ba
