Warp stop motion detector and circular loom

Abstract

The warp band stop motion (1) for looms, in particular circular looms, comprises a sensor piece (2, 22, 32) that has a passage (3a) for a warp band (K, K1, K2). The sensor piece (2, 22, 32) can be moved back and forth between a preloaded rest position (R) and a working position (A), into which the sensor piece can be moved by a tensile stress (F) of the warp band (K, K1, K2) passing through the sensor piece. A rest position detector (5) detects the presence of the sensor piece (2, 22, 32) in the rest position (R) or the approach of the sensor piece (2, 22, 32) toward the rest position (R). If the rest position (R) of the sensor piece (2, 22, 32) or the approach of the sensor piece toward the rest position is detected, the detector (5) emits a rest position signal (6). A warp band clamping device (15, 16; 16, 17; 34, 35) is provided, between which device and the sensor piece (2, 22, 32) the warp band (K, K1, K2) can be clamped when the sensor piece (2, 22, 32) moves into the rest position (R) thereof.

Description

technical field [0001] The invention relates to a warp thread monitor (Kettböndchenwöchter) for a weaving machine, in particular a circular loom (Rundwebmaschine), with: ) channel, wherein the sensor element can be between a rest position (the sensor element can be pretensioned into this rest position) and an operating position (the sensor element can be moved into this operating position by the tensile stress of the warp thread thread passing through the channel) and a rest position detector, which detects the sensor device present in the rest position or the sensor device approaches the rest position, and sends out a rest position signal when the rest position of the sensor device or its approach to the rest position is detected. [0002] Furthermore, the invention relates to a circular loom, at which a plurality of warp threads can be guided to a circular reed (Rundriet), with a main drive and a control device, wherein the circular loom is equipped with There are warp thre...

Problems solved by technology

[0007] However, it has been shown that simply displaying the ends of the warp yarn ribbons generally does not prevent damage to the circular loom, because the associated warp yarns are Strands move unrestricted around a circular loom) to form loops that become entangled with other warp yarns or wrap around movable parts of a circular loom and which interfere with prescribed movement

The consequences of this unrestricted "flying" warp tape ends in circular looms can be catastrophic and up to cause far-reaching damage to the circular loom
