Abstract: An electronic computer control for a hydraulic actuator for shifting a needle bar to different transverse positions in a tufting machine. The computer control directs the hydraulic actuator to be driven in response to the predetermined stitch pattern information in the computer control circuit, which determines the amount of relative tansverse shifting of the needle bar for each stitch location, in such a manner that the needle bar is shifted transversely only a needle gauge, or a multiple needle gauge, at a time and only while the needles are out of the backing fabric. The computer control also controls the velocity of the transverse movement of the needle bar in a gradual manner to minimize any shock created by the transverse movement of the needle bar upon the tufting machine.
