Abstract
A device to detect the tension uniformity of a belt in a weft inserting member of a shuttleless loom wherein a belt anchored at its ends to fixed contiguous points and guided by rollers on a movable carriage with reciprocating motion serves to to control a gripper for laying down weft threads. The device comprises a cylindrical anchoring body on which an end of the belt is partly wound, there being interposed between the anchoring body and the belt section an elastic member mounted on the anchoring body and urged by the belt section against the body by the tension in the belt. Upon slackening of the belt, the elastic member displaces the belt section to produce closure of a switch which detects the reduction in the belt tension.
Claims7
A device to detect the tension uniformity of a belt in a weft inserting member of a shuttleless loom of the type having a belt anchored at its ends to fixed contiguous points, guide rollers for said belt, and a movable carriage supporting said rollers and movable with reciprocating motion to control a gripper for insertion of weft threads, said device comprising a cylindrical anchoring body on which one belt end is partly wound, an elastic means mounted on said body and disposed between the belt end and said body, said elastic means having resiliency and tending to displace the belt section wound on said body and serving to displace the belt section in the event of a reduction in the belt tension, and means for detecting such displacement of the belt section.
