Abstract
An improved presser foot device for straight bar knitting machines with double V needle beds, characterized by the fact that means are provided whereby the presser foot can be moved by the program controller of the machine automatically from one to another of two preselected hold down levels, one of which is appropriate for 'rib border' knitting and the other for 'jersey' knitting. A specific shape of presser foot is also disclosed, comprising a thin, flat configuration including a first wide section located towards the advancing end of the presser foot, a second markedly narrower section connected to the first section at an abrupt change in width and trailing the first section with respect to the advancing direction of the presser foot, and a third section trailing the second section, the third section being wider than the second section and connected to the latter along a gradually tapered section.
