Abstract: The invention relates to a method and an apparatus for forming an insertion-side fabric selvedge (35) on a gripper weaving machine, whereby: a) selectively one of several weft threads (3, 4, 43, 44) that are provided on bobbins (1, 2, 41, 42) is positioned in the running path (5) of a gripper (6), while the other weft threads (3, 4, 43, 44) are held outside of the running path, whereby: b) the weft thread positioned in the running path is grasped and inserted into a loom shed by the gripper (6), whereby: c) thereafter the inserted weft thread (3) is beat-up against a binding line (33) by means of a weaving reed (31), whereby: d) the inserted weft thread (3) is cut-off on the insertion side directly after the beat-up, and e) the bobbin-side weft thread end of a respective cut-off weft thread (3) is respectively grasped and held by a different suction chamber of a suction chamber block (10, 20).
Abstract: A method and apparatus for the removal of one or more lateral yarns from a woven industrial textile to prepare it for seaming. The apparatus consists of a movable table, a clamping device to hold the fabric, and a yarn removal device, consisting of a cutter and a combined hooked needle & thread catcher. In operation, the yarn removal device moves both vertically into and out of the fabric plane, and horizontally parallel to the longitudinal yarns. The yarn removal device pierces the fabric at two locations, cuts one or more yarns, and then grasps the cut section(s) to pull them down and out of the fabric plane. The cycle is repeated to form a longitudinal channel of desired length; the device is then moved laterally and the cycle repeated until an open channel parallel with the lateral fabric edge is accomplished.
