Abstract

A loom picking mechanism comprises a picking spring such as a torsion rod 1, and a picking spring tensioning system comprising a clutch 11, 12, a cam disc 8 which is mounted to be freely rotatable and is connected to be rotated by the clutch 11, 12, and a pivoted cam follower lever 3 cooperating with the cam disc 8 to actuate a picking element 4 engageable with the shuttle 5, the cam disc shaving a cam section (such as a depression) which is so shaped that the cam disc is accelerated by the picking spring energy released during the pick so that the driven part 11 of the clutch leads the driving part 12 of the clutch and thereafter the spring is partially stressed for the next pick by the momentum of the cam disc as the cam follower moves out of the depression. <IMAGE>
