Abstract
A scissors mechanism for cutting the weft thread in a shuttleless loom performs an excess stroke to bring the scissors mechanism, which is combined with a clamping mechanism, as close to the weft thread insertion gripper as possible in order to reduce weft thread waste. For this purpose, the fixed scissors blade is tiltable between a working position and a rest position in a plane extending substantially perpendicularly to the weft thread insertion direction. The movable scissors blade cooperates with a clamping arm for clamping the weft thread just prior to its cutting. For this purpose the movable scissors blade carries a clamping jaw next to its cutting edge and the clamping jaw cooperates with a clamping plate attached to a clamping arm coaxially mounted with the movable scissors blade. An excess stroke motion of the entire mechanism moves the clamp formed by the clamping jaw and the clamping plate into a position close to the gripper guide track after the weft thread has been clamped in the scissors clamp.
