The crossing thread supply system has four bobbin pairs which are disposed on rotatable disk-shaped elements. Each bobbin pair is guided downwardly through a tube which rotates with a respective rotatable element in non-rotatable relative relation. The tube extends obliquely so that all of the tubes deliver the respective thread pairs to twisting disks located in a relatively narrow lane.

Crossing thread supply system for a weaving machine

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.

The heddle carrying rods are provided with open ended axially extending slots in each end. Connectors are provided having longitudinal edges complementary to the longitudinal edges of the slots to define a tongue and groove connection. One end of a connector may be slidably connected in the slot with the opposite end having a locking configuration to retain the connector in the slot for preventing the removal of heddles from the rod, a bevelled end piece configuration to facilitate the insertion of heddles on the rod or an identical symmetrical configuration for insertion into a slot in another rod to facilitate transfer of heddles from one rod to another.
