Knitting machine

The invention relates to a knitting machine, in particular circular knitting machines, the circumferential bathing cylinder of which is provided with grooves or seat braids, in which Knitting needles are arranged so that they can be pushed longer, which in the course of the Striokrorganges either by their own Working feet and / or with the help of τοη actuating means, like s.B. Between · töeeern, Ibisterstässern and the like are operated, which also have working fie those in a lock jacket of a sole system are performed, this Sohlofisystem from stationary and / or movable visual parts.

Existing known designs τοη SehloSteile in Lock jacket, in particular τοη circular knitting machine, are

designed in such a way that individual sole parts on working feet yon hadels, intermediate pods, pattern pods and the like, gate to all with lükeicht on those exercising them Act puncture. For this reason »became Bis now on an exact construction of the work »™ or stitch pulling edges of these lock parts no special Attention directed. This latsaehe expressed it unfavorably in the mechanical stress of the actuated ! Bearings, especially with knitting needles. As long as the course of the working feet did not exceed the usually used speed, the existing speed was known construction of the knitting needles and especially the hooks of these needles designed in such a way that the claim was within the το »material goal given strength limits.

However, there will be ways of increasing performance Clay knitting machines wanted. One of these possibilities is to increase the number of streak systems, however is this possibility through the bath cylinder limited available construction space. His second way of increasing performance is based in an increase in the speed of the Hadelsy! loader, through which you can also see the speed of movement of the Elevated working feet in the lock system of the knitting machine. This increase in speed has shown that the existing construction of individual lock parts unrolling is and that these are not up to the requirements at increased speeds.

The invention avoids this iaclittile. The invention
