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 th

Embodiment Construction

[0020]FIG. 1 shows a loom according to a first example of the present invention as a schematic view to explain the basic movement. In a gripper loom, the warp threads 2 for producing a ribbon fabric 10 form an upper shed 5 and a lower shed 4 for inserting a weft-thread by means of a weft-insertion needle 7 or a gripper. A reed 1 is arranged in a conventional manner in order to rest against the inserted weft-threads against the previously produced woven material 10.

[0021]The warp-laying device 9 is dipped in through the upper shed 5 into the lower shed 4. At the same time the reed 1 moves backward. The warp-laying device 9 can be moved in the direction of the reed 1 and also downwards into the lower shed 4. In the embodiment presented here, the warp-laying device 9 follows the movement of the reed 1. However, the warp-laying device can also be switched off or it can be dipped in at variable frequencies depending on the bonding.

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...
