ABSTRACT:
A shuttleless loom is equipped with a displacement device for the control member or rail of the clamping device of the gripper, whereby the control rail can be displaced in parallel to the thread inserting motion of the gripper. This displacement of the control rail permits the proper presentation and transfer of the weft threads into the clamping device of the gripper even if the weft thread fan contains a substantial number of weft threads. This control rail displacement in the direction of the thread insertion into the loom shed takes place at each picking or inserting movement of the gripper and is substantially synchronous with the gripper motion after a thread transfer. When the number of threads in the thread fan is relatively small, the displacement device can be switched off.
