ABSTRACT:
The guide bars of a warp knitting machine include a compensation means which allows the guides on the guide bar to pass more precisely between the gaps in the needles of an associated needle bed. The compensation means is located between a pattern wheel follower and a push rod which is rotatably attached at one end to the guide bar. An adjustable lever is attached at one end to the push rod and at the other end to a rotatable pin. The rotatable pin is associated with a housing which contains an eccentric roller cam. The eccentric roller cam is directly connected to the rotatable pin and is displaceable in direct response to the rotation of the rotatable pin. A short rod having an angled face is adapted to make contact with the eccentric roller cam. The other end of the rod is pivotally connected to one end of the push rod by a ball joint. When the guide bar is displaced from one needle bed to another the push rod and accordingly, the lever follow that motion. The motion of the lever rotates the rotatable pin which in turn displaces the roller cam. The displacement of the roller cam forces the push rod forward thereby compensating for the assymetric movement of the guide bar.
