Description of knitting machine
Yarn guide
Active thread clamp The active thread clamp is found under the friction feed wheel. It is integrated
in the lateral safety door. The thread clamp is positioned in such a manner that
each track of the friction feed wheel is arranged corresponding to a track of the
thread clamp. In all there are 8 tracks available.
Lateral yarn guide
Lateral yarn guide
In the case of a friction feed wheel sometimes a problem appears:
When a thread is not knitted over a longer period of time it is possible that the
friction feed wheel releases some threads because of the friction and thereby
the lateral yarn tensioner swivels so mush outwards that the machine stops.
This hinders the thread clamp. If the yarn tensioner swivels over the angle by
approx. 45 degree, the clamp closes automatically. If the thread is knitted
again the yarn tensioner swivels inwards and the clamp is open.
Lateral yarn tensioner
Lateral yarn tensioner The lateral yarn tensioner has two tasks:
In the case of a yarn breakage the side yarn tensioner swivels outwards and
switches off the knitting machine. On the upper end of the yarn tensioner a
magnet is fixed that releases a contact in the lateral safety door without
touching it.

Function Description
Control the thread Switch off the knitting machine in case of a thread
break or yarn end.
Tension the thread When the yarn carrier moves on the yarn tensioner,
it can hold the threads that are not yet being knitted
in a tensioned state. The yarn tensioner swivels and
holds the threads tensioned.
