A circular knitting machine is described which has a needle cylinder (), at least one cylinder cam segment (), a dial arrangement () having a dial () and at least one dial cam segment (), an axis of rotation (), which is coaxial with the needle cylinder () and the dial arrangement (), and at least one thread guide element () intended to guide a thread (). The cylinder cam segment () together with the thread guide element (), and the dial cam segment () are rotatable about the rotational axis () relative to one another. The needle cylinder (), and the dial arrangement () together with the thread guide () are moreover disposed displaceable relative to one another and parallel to the rotational axis (). According to the invention, the thread guide element () is mounted moveable on the cylinder cam segment () (FIG.).

Circular knitting machine having at least one moveable thread guide

The invention relates to a yarn changer for knitting machines, with 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) 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 in such operative connection through a reverse-coupling mechanism (114-120) 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 invention moreover concerns a knitting machine equipped with the yarn changer, especially a rib circular knitting machine, in which a yarn catcher cooperating with the yarn changer is built into the dial.
