A knitting machine has a lowering cam which acts on the butts of the needles to lower the needles in an active stroke. A stop cam associated with the lowering cam acts on the butts to decelerate the needles at the end of the stroke. The relative positions of the lowering cam and the stop cam can be adjusted in two mutually transverse directions to ensure smooth engagement of the butts with the stop cam.
