ABSTRACT:
A punch for a pattern card for textile machines, for instance shedding machines or automatic knitting machines, having a step-by-step transport device and a centering device for pin wheels arranged on a shaft, for the transport of the pattern card. In order to increase the punching output and reduce the noise level, the step-by-step transport device comprises a stepping motor, and a coupling is arranged between the stepping motor and the shaft, and a centering wheel, which cooperates with a lever which simultaneously actuates the coupling, is fastened on the shaft.
