Abstract
A presser foot, for a knitting machine having independently operable needles located in opposed needle beds, has a leading portion and a trailing portion extending rearwardly from the leading portion. The leading portion comprises a member with a smooth surface adapted to contact knitted loops when the presser foot is in use, the forward part of this smooth surface being higher than the rearward part and the two parts having a smooth transition between them. This member is adapted to resist deformation by the forces applied by knitted loops and is so shaped that the inclination of the forward part of said smooth surface which first contacts the knitted loops during relative movement of machine needles and presser foot, in use, is inclined to the direction of said relative movement at an angle less than 35.degree.. The trailing portion of the presser foot, at the location where it departs from the leading portion, is at a level substantially the same as or higher than the level of the rearmost stitch-contacting section of said leading portion. The trailing portion is adapted to be resiliently deflected in an upward direction by the forces applied to it, in use, by knitted loops.
