Abstract

According to the invention the labels (22) are produced in a broad woven fabric (21) comprising ground warp yarn (4) and ground weft yarn (5) for a ground woven fabric (11), embroidery weft yarn (12) which forms a figure and code weft yarn (10) which forms a barcode, said yarn being distinguishable from the ground warp yarn only in a light outside the visible spectrum. In the broad woven fabric (21) several labels (22) are produced whose longitudinal sides (1) adjoin each other in the weft direction and remain unfolded and whose lateral sides (2) are adjacent to each other in the warp direction and can be folded. The embroidery weft yarn (12) and the code weft yarn (10) extend parallel to each other and at a distance from the longitudinal sides (1) so that the backs of the labels (22) are evenly covered and thus uniformly transparent. The broad woven fabric (21) is cut along the lateral sides (2) into strips (25) each consisting of transverse labels (22) which are situated one behind the other in the warp direction. The labels (22) are then separated into individual labels by cuts along their longitudinal sides (1), which produces soft cutting edges (16) in the ground woven fabric (11) which do not irritate the skin.

Claims

1. A woven label made from fusible thread material, comprising:

a ground fabric formed from ground warp threads and ground weft threads, said ground fabric having nonfolded longitudinal sides and foldable narrow sides; and

code weft threads which make an invisible bar code and, when observed in visible light, are essentially visually identical to the ground weft threads and can be distinguished from the ground weft threads when exposed to radiation taking effect outside the visible range and which are tied in the ground fabric,

wherein the longitudinal sides are oriented transversely to the ground warp threads and the code weft threads run parallel to and at a distance from the longitudinal sides, said code weft threads floating below the ground fabric and being led onto the top side of the ground fabric in order to form a bar code.

2. The label as claimed in claim 1, wherein the label has embroidery weft thread which form a figure and run parallel to and at a distance from the longitudinal sides, said embroidery weft threads floating below the ground fabric and being led upward to form the figure.

3. The label as claimed in claim 2, wherein the ground fabric has margin regions and the floating embroidery weft threads are removed in the margin regions of the narrow sides of the label.

4. The label as claimed in claim 2, wherein the label has marginal regions folded on the narrow sides.

5. The label as claimed in claim 1, wherein the ground fabric has margin regions and the floating code weft threads are removed in the margin regions of the narrow sides of the label.

6. The label as claimed in claim 5, wherein the label has marginal regions folded on the narrow sides.

7. The label as claimed in claim 1, wherein the label has marginal regions folded on the narrow sides.
