The invention relates to a device on circular knitting machines for taking thread along in the form of a circumferential toothed ring.

In the previously known circular knitting machines there is, in spite of the above, the sinker cam part protruding, toothed knife ring the possibility that the thread between the fixed Can get sinker lock part and the rotating knife ring as a result of the required bearing play. Attempts have been made to avert this risk by using circular knitting machines with double-edge transfer plates a special switch-off device is provided, which then switches off the circular knitting machine, if the thread is below the sinker lock part to behind the double-edge transfer sinkers got.

The risk of entering the space between the sinker lock part and the rotating knife ring usually occurs at the point in time when a first stocking is completely knitted and the Thread is stripped from the needles in preparation for the beginning of the next knitting process. After this a stocking has been knitted, the toe part of the same is made by means of a single thread with the Thread guides in connection, this thread is not incorporated into the stocking. For loosening the stocking from the circular knitting machine this thread is now severed or cut, so that a loose There is a thread end that can enter the space between the sinker lock part and the knife ring.

The invention is now based on the object of creating a device on circular knitting machines, by means of which with security a penetration of the thread into the caused by the bearing play Space between sinker lock part and knife ring is prevented.

This object is achieved according to the invention by arranging one over the outer edges of the sinker lock cap and of the sinker part projecting shoulder and by arranging one of the webs the dial overlapping projection on the toothed ring.

The invention is explained below, for example, with reference to the drawings. It shows

In Fig. 1 shows a multi-system circular knitting machine 10 with tongue ring 11 and needle circle 12 and a first row of thread guides 13 and a second row of thread guides 14. On the needle circle 12, the dial 15 is arranged with a fixed sinker lock cap 16, which carries a knife and a clamp 17. As shown in Figure 2, dial 15 has vertical webs 21, 22 which support double-edge transfer sinkers 23 for radial reciprocating movement under the action of sinker member 24 located in the sinker cap.

It is a To the toothed ring 31 with the dial to toothed ring 31, as in the F i g. 1-6, to rotate, pins 36 are arranged in pairs at locations around the circumference of the toothed ring, spaced apart to rotate with dial 15. The ring gear 31 has a lower surface 32 31 arranged around it. The pins 36 are provided with lower ones that can rest on the webs 21 and are provided on 5 head parts 37 which are relatively enlarged outer stand between the webs 21 corresponds so that the circumference of the webs 21 protrudes.
