摘要:
The invention relates to a method for applying forces and motions to warp threads (1, 1') of a weaving machine, comprising the following steps: deflecting the warp threads (1, 1') via a thread-deflecting element (2), which is supported in such a way that the thread-deflecting element can be pivoted about a pivot axis (3); applying spring forces to the thread-deflecting element (2) by means of more than three force application points (5) along a first line (6), which extends parallel to the pivot axis (3), wherein the spring forces are applied by at least one spring element (4); applying a specified forced-oscillation motion (38) to the thread-deflecting element (2), wherein said motion (38) is applied by a drive means (7) via a drive element (8), wherein the forces on the thread-deflecting element (2) are supported partially on at least one spring element (4) by means of the thread-deflecting element (2) and partially on the drive means (7) by means of the drive element (8). The invention further relates to a corresponding device.

Deflecting device (3) for a chain composed of tenter clips (1) having running rollers (2) for transporting a moving material web, having a sprocket (4) and having a guide rail (5) with at least two tracks (6.1, 6.2) for the running rollers (2) of the tenter clips (1). The two tracks (6.1, 6.2) are each arranged on two sides, facing away from one another, of the guide rail (5), parallel to the rotation axis of the sprocket (4). The guide rail (5) has at least one curved section (5.2) for deflecting the chain. Provided in the region of the curved section (5.2) of the guide rail (5) are connecting elements (8, 9, 10) via which the guide rail (5) is connected to the deflecting device (3). A plurality of connecting elements (8, 9, 10) are embodied such that at least a part of the curved section (5.2) of the guide rail (5) is radially displaceable with respect to the sprocket (4).

The invention relates to a weaving machine having a device for forming a leno selvedge (1), comprising a first guiding apparatus (12.1), which is designed as a linear guide, for guiding a first leno needle (11.1) and comprising a first needle drive (13.1). The device also comprises a second guiding apparatus (12.2), which is designed as a linear guide, for guiding a second leno needle (11.2) and comprises a second needle drive (13.2). The two guiding apparatuses (12.1, 12.2) and the two needle drives (13.1, 13.2) are fastened to a carrier (14) that can be driven in a longitudinal direction of the leno needles (11). The leno needles (11) can be driven in two planes (15.1, 15.2) that are parallel to each other by means of the carrier (14) and by means of the needle drives (13). The two planes (15.1, 15.2) extend in a weft direction (5) of the weaving machine and in the longitudinal direction of the leno needles (11). In addition, a thread-guiding element (16) is present, which has two guiding contours (17.1, 17.2) that extend parallel to the longitudinal direction of the leno needles (11). The thread-guiding element (16) is arranged in a region between the shedding elements (8) and the two planes (15.1, 15.2) of the leno needles (11).
摘要:
For weaving pattern formation of a woven fabric having weft threads (3), warp threads (1) and effect threads (2), data sets (20) are generated according to a method, in which data values of weft numbers (30) and of positions of weave points (P) of an effect thread (2) with the weft threads (3) in the pattern repeat (29) are derived. Said data sets (20) are supplemented by further data values (31, 32, 33, 34) which are derived from the weaving pattern, in such a way that they form a point paper design (28) for a weaving pattern with additional weft effects. In a weaving machine having devices for displacing effect threads (2) in the weft direction (12), the weaving pattern formation is derived from the data sets (20) of said point paper design (28).
