Abstract
A device for the offset control of the needle beds of a flat-bed knitting machine has a servomotor for the adjustment of one of the needle beds in relation to the other and has a position control circuit controlling the servomotor. So that it is possible in such a device, after an unintentional shut-down of the machine during knitting, to exactly reconstruct or reset the original or the about to be set position of the movable needle bed without damaging the knitted fabric present in the machine just produced, an actual value transducer device performing a set point/actual value comparison is provided, having an incremental transducer, the high resolution and accuracy of which is many times finer than the needle gauge and which aditionally has reference marks at least at the interval of the needle gauge of the needle bed but with the same high degree of accuracy, and an absolute value transducer, the resolution of which is at least the same as, preferably higher than the distance of the reference marks of the incremental transducer.
