Loom for producing woven goods or material with an incorporated cover thread

Abstract

In order to improve a loom for producing woven material (10) with an incorporated cover thread (12), it is proposed to provide a laying device for at least one cover thread (12) and also a warp-laying device (9) with warp-laying elements (14) for laying further warp threads (8). The warp-laying device (9) is designed such that it can make the further warp threads (8) penetrate from a starting position through the upper shed (5) to the lower shed (4), or through the lower shed to the upper shed, and therefore the weft-insertion device (7) crosses the further warp threads (8). The laying device has at least one cover-thread guide (13) which, in the starting position of the warp-laying device (9), can be displaced transversely to the warp threads (2) by way of a transverse-movement means.

Description

[0001]This application claims priority from PCT Application No. PCT / EP2011 / 059494 filed Jun. 8, 2011 which claims priority from European Application No. EP 10165399.6 filed on Jun. 9, 2010, which applications are incorporated herein by reference.TECHNICAL FIELD [0002]The invention relates to a loom for producing woven material with an incorporated cover thread.BACKGROUND OF THE INVENTION [0003]A loom of the above mentioned type is known from CH 490 541. Therein, attachment threads are arranged by means of feed needles while weaving a ribbon. There are no suggestions whatsoever as to how the ribbon needle loom could carry out in advantageous manner the weaving in of a conductive thread, particularly of an antenna thread. A similar technology has been independently disclosed in U.S. Pat. No. 3,796,234.[0004]From WO 2007 / 071077 A1 it is known to incorporate a conductive thread in disparate ways by having the feed needle arranged on a shaft that is oriented transversely to the warp dire...

AI Technical Summary

Benefits of technology

The invention provides a loom that can produce woven material with an incorporated cover thread without significantly changing the material. The loom has a unique design that allows for the cover thread to be tied off even with a transverse movement of the cover thread guide, resulting in a seamless appearance on the finished material. The loom also has a warp-laying device with additional warp threads that can be moved and placed in different positions on the material. This avoids the issue of the cover threads becoming a part of the backing fabric and changing the structure. The warp-laying device also has transverse moving means that allow it to move back and forth over the warp threads. Overall, the invention provides a loom that can easily and efficiently produce woven material with cover threads.

Problems solved by technology

In this manner the loom is able to apply a cover thread without noticeably changing the woven material—in contrast to the loom of JP 2005 / 015954 A. Due to the fact that the loom comprises—in addition to and independently of the laying device for the at least one cover thread—a warp-laying device with a plurality of warp-laying elements arranged adjacent to each other for laying additional warp threads, the disadvantage of JP 2005 / 015954 A that the cover threads become a part of the backing fabric and thus change the structure is avoided.
