Patent number: 4139997Abstract: A patterning device employs an elongated strip which is fixed between an operating element, such as a guide bar of a warp knitting machine, and a fixed support point. In addition, the patterning device has a displacing element in the form of a rotatable eccentric or a reciprocally mounted roller which is used to deflect the strip between two points intermediately of the length of the strip so as to exert a pulling force on the guide bar. The amount of deflection of the strip determines the amount of movement of the guide bar. The guide bar can be returned by way of a spring or by a second strip which is deflected in similar manner as the first strip by a displacing element. In one embodiment, a single displacing element is used for deflecting purposes while in other embodiments, a multiplicity of displacing elements are used. The strips may be attached directly to the guide bar or indirectly, for example, over a pivotally mounted lever.Type: GrantFiled: March 4, 1977Date of Patent: February 20, 1979Assignee: Sulzer Brothers LimitedInventor: Peter Riesen

Steering compensation means for guide bars utilized in warp knitting machines having two needle beds
Patent number: 4034582Abstract: 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.Type: GrantFiled: July 16, 1976Date of Patent: July 12, 1977Assignee: Karl Mayer Textilmaschinenfabrik GmbHInventor: Johann Oppolzer -
