ABSTRACT:
As the carriage of a flatbed knitting machine traverses the needle bed, a lse generator which comprises a toothed disc and two cycle signallers at its circumference produces pulses in synchronism with the carriage movement and corresponding to the needle cycle for electronic control of the machine. The toothed disc has a tooth pitch which corresponds in whole number multiples with the pitch of the needles in the bed. The pulse generator may be located on the machine frame or on the carriage. In the former case the carriage can have a pick-up which entrains a chain stretched on the machine frame with the toothed disc rotatable jointly with one of the sprocket wheels for the chain. In the latter case the toothed disc, carried by the carriage may be rotated by a coupled pinion which meshes with a rack stationary on the frame and co-extensive with the traverse of the carriage. In each case the pulse generator produces synchronized control pulses without direct scanning of the needles in the bed.
