Abstract
A knitting machine is comprised of a first pair of cooperating flat needle beds and a second pair of cooperating flat needle beds positioned behind the first. Cam slides are provided with cams for controlling the motions of the needles in the needle beds. The cam slides are mounted for travel in a single direction along a closed path extending around the two pairs of needle beds. At least one, but preferably all, of the cam slides is provided with cam arrangements capable of causing needles to perform normal-knitting motion, loop-delivery motion for loop transfer and also loop-acceptance motion for loop transfer. As the cam slide makes one trip in one direction along one pair of needle beds, it can cause loops to be transferred in both directions during the single trip. When a switchover to normal knitting is to be made, the cam slide need not be replaced but is merely reset for normal knitting.
