Abstract
A flat knitting machine including a presser foot assembly comprising a support mounted on the machine for movement along the needle array of the machine and at least one presser foot mounted on the support. The assembly includes a supporting arm carried on the support and itself carrying a slider on which a presser foot is mounted, the supporting arm providing a structure for effecting guided displacement of the slider up-and-down in relation to the needles. Resilient means, such as one or more springs, are arranged to urge the slider and presser foot down, away from the support, so that the presser foot can ride up on the supporting arm against the pressure of the resilient means and thus the whole of the presser foot extending from in advance of the rising needles to the rear of the fully raised needle position is resiliently mounted in the machine.
