Strickmaschine und Fadenwechselvorrichtung

摘要

A yarn changer for knitting machines has swinging yarn fingers (22c, 22d), which comprise finger bodies and guide bodies (66c, 66d) having cutting and clamping elements (69, 71) slidable on the finger bodies, and with an opener (121) and closer (122) for the cutting and clamping elements both associated with all yarn fingers in common. In order to reduce the number of moving parts and the noise occurring in operation of the yarn changer, the opener (121) and closer (122) are coupled together to move in opposite directions by a mechanism (114-120) so that they can be actuated in common by an associated cam track (102) acting on a control member (114). The control member (114) is preferably only in the working range of the cam track (102) when a yarn change is to be effected. The mechanism coupling the opener and closer may comprise a two-armed lever (116) or a pinion meshing with two racks. The yarn changer may be incorporated in a circular knitting machine with a dial and a yarn catcher cooperating with the yarn changer is built into the dial.
