Abstract: The disclosure relates to a stitch press movement mechanism for a knitting machine having at least two needlebeds. The movement mechanism is based upon the rotational movement of a serrated wheel in engagement with a single rack. The movement or change of positions of the stitch press slide blocks is accomplished by the interaction and cooperation between a lever attached to the stitch press and a lug and a raised bearing surface located on the serrated wheel. The stitch press movement mechanism disclosed is particularly advantageous because it eliminates a number of the blows or jolts received by the fragile stick press slide blocks and thus promotes longer equipment life.
