Abstract
In a pick finder, a gear which is driven by a motor sits on a sleeve, which has thereon a tooth of a single-tooth coupling. For tensioning the return spring which effects engagement of the coupling, the gear has on the front side an annular control cam surface with recesses and cams, and rigid rollers can be brought into contact therewith through axial movement thereof with respect to the shaft. Based on the size and the placement of the respective rollers, engagement thereof with the cam surface on the gear rotated by the drive motor of the pick finder will move the sleeve into a position for pick finding or for slow-speed run of the weaving machine with the shed-forming machine. At the same time, the return spring is tensioned by the force of the motor.
