Abstract
The crossing thread supply system for the weaving machine employs a rotatable bobbin carrier and a thread tensioning means for controlling a thread pay-out from a bobbin on the carrier as a function of thread tension. The tensioning means employs a control lever which is pivotable under the influence of the paid-out thread and a pivoting lever which engages via a pawl with a ratchet wheel connected to the bobbin carrier. The control lever serves to pivot the pivoting lever when moved to an innermost position. This disengages the pawl from the ratchet wheel to permit indexing of the ratchet wheel and bobbin carrier.
