A method and apparatus for weaving a three-dimensional fabric involves inserting simultaneously a parallel weft yarns into the sheds between multiple warp yarn layers and selectively inserting at least one group of binder yarns between parallel spaced warp yarns. The group of binder yarns are moved relative to the warp yarns between weft insertions. The yarns may be moved between more than two positions relative to the warp yarns during weaving of the fabric so as to insert binder yarns. In one embodiment the binder yarns are moved such that they extend in a direction that is not orthogonal to the warp yarns.

A heddle (10) is provided for weaving strip-shaped warp yarn. Said heddle (10) includes a heddle shaft (12) formed by two shaft parts (13). Said shaft parts (13) are placed on top of each other in a respective end section (15) of the heddle shaft (12) and interconnected. The end eyelets (16) of the heddle (10) are also in said end section (15). To form a yarn eye between both shaft parts (13), two separate warp yarn guiding bodies (20) are placed therebetween. To determine the position of the warp yarn guiding body (20) with respect to the heddle shaft (12), at least one shaft projection (22) is produced by stamping and subsequent bending or embossing each shaft part (13) for each warp yarn guiding body (20). Said shaft projection (22) engages in an associated recess (25) of the warp yarn guiding body (20), and a bonding connection is produced.

A heddle (1), preferably for the processing of tape-like material, includes at least two bands (2, 3), which form the heddle shaft (24). At least one component (6, 7), which limits a thread eye (8), or one of the two bands (2, 3) has at least one fastening element (9, 10), which connects the component and the band. The two bands (2, 3) make mutual contact above and below the thread eye (8) at joins (13, 14). At least one join (13, 14) is spaced from the thread eye (8) by a distance A, which is, at the most, half as great as the distance (D) between the thread eye (8) and the end loop (17) nearest in each case to the join (13, 14).

An apparatus for detecting a break in a warp yarn in a loom includes a heald, a heald frame, a carrier rod, a sensor, a controller and a signal line. The heald is made of a resin material for guiding a warp yarn. The heald frame performs a shedding operation of warp yarns and has the carrier rod for supporting a plurality of the healds. The sensor is provided in the heald for sensing a deformation of the heald caused by a tension of the warp yarn and outputting a signal. The controller is provided for determining a condition of the break in the warp yarn based on the signal of the sensor. The signal line electrically connects to the sensor and the controller.

A heald in accordance with the invention is preferably fabricated of a round wire, said wire having a center section (9). This section has an octagonal cross-section that is defined by two legs that are connected to each other by a thin strip. In so doing, the heald body (2) may be split to accommodate a thread eye insert (6). The thread eye insert (6) is preferably secured with the use of an adhesive in the resultant opening (16).
摘要:
This process includes steps consisting in manufacturing an eyelet for guiding a warp yarn, making, in a threadlike element, an opening for receiving the eyelet, and placing and immobilizing the eyelet in the opening. During manufacture of the eyelet at least two projecting tabs offset from each other along its edge and perpendicularly to the principal faces of this eyelet are formed on this outer edge. During the placement of the eyelet in the opening, a part of the edge of the opening is inserted between the tabs. As a variant, the tabs can be provided on the edge of the opening.
