Abstract
A pick-finding mechanism is arranged between a weaving machine and a shed-forming machine. A sleeve of a gear sits rotatably on a shaft, which gear is driven by the weaving machine. A single-tooth coupling can transmit forces from the gear to a sliding sleeve which is secured by a key to the shaft and can be moved axially of the shaft by a switch lever. The shaft can be driven through a multiple-tooth coupling by a motor and a drive gear. The switch lever serves to couple and uncouple the couplings. To find the pick, the single-tooth coupling is disengaged and the multi-tooth coupling is engaged. The weaving machine and dobby can be driven together in phase and in both directions by the motor at slow speed, by simultaneously engaging both couplings. This slow or creeping speed permits observation of the functioning and stopping of the machines in any desired position at any time.
