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.
Claims19
In a warp knitting machine, a jacquard control arrangement comprising:
- a control means for providing electrical command signals signifying a jacquard sequence;
- at least one guide bar;
- a plurality of guides supported by said guide bar and displaceable effectively by at least one needle space;
- and
- a plurality of piezoelectric transducers coupled to said control means and separately mounted at corresponding ones of said guides for displacing said guides in response to said electrical command signals, said piezoelectric transducers each comprising a deflecting transducer having one end attached to the guide bar and another end rigidly attached to a corresponding one of said guides, said deflecting transducers being mounted between the guides and the guide bar.
