Abstract

A device for the control of a flat-bed knitting machine for the positional determination at lift reversal of the carriage assembly driven by a reversible motor has a phase-shifted pulse generator device on the carriage assembly which can be moved back and forth and a stationary pulse generator board device in the area of the needle bed arrangement. With such a device a reproducible lift reversal can be performed in the area of the ends of the needle bed as well as at any desired location along the needle bed arrangement, the pulse generator board device has a pulse generator board extending along a needle bed of the needle bed arrangement. During lift reversal the pulse sequences of a pulse generator associated with the pulse generator board are detected in a calculator unit and compared with the pulses associated with the locations for the beginning or alternatively, the end of the lift reversal which have been preset by a program, and the calculator unit performs a speed change during the detection of the lift reversal pulses in dependence an overrun set by the program and the present working speed.
