ABSTRACT:
Thread clamp for a warp end tying-in machine. In such a clamp, cam control means mechanically related to the remainder of the machine are provided for positively opening the clamps in order that the thread may be inserted therein without hindrance. The clamp is thereupon permitted to close and the mechanical means retracted therefrom in order that the clamp may be held in closed condition solely by the tension of adjustable resilient means applied thereto. With the mechanical means remaining inoperative with respect to the clamp, same is moved through a conventional operating cycle and back to its point of beginning. Mechanical means are thereupon again activated to open the clamp against the urging of said spring whereby the thread may be removed without restriction therefrom.
