ABSTRACT:
There is provided a warp knitting machine with a jacquard control mechanism. Piezoelectric transducers are provided to each individual guide of a guide bar. These transducers can displace the guides by the application of a control potential. In particular, the piezoelectric transducers are formed as deflecting transducers. These transducers can comprise a plate-like carrier upon which there is provided at least one active layer of piezoelectric material. A holding arrangement of the guide bar can rigidly support one end segment of the plate, whose other end can carry the guide. This gives rise to a very easily constructed jacquard arrangement.
