Abstract
A warp knitting machine having a main shaft has at least one bar mounted to reciprocate in accordance with a predetermined schedule. The machine also has an electrically activated drive arrangement with a body made of a material that can alter at least one of its dimensions in dependence upon the magnitude of an applied field. The machine also has a control arrangement coupled to the drive arrangement for providing an electrical signal thereto, in accordance with the predetermined schedule and in dependence upon the angular displacement of the main shaft. This electrical signal can establish the applied field with a predetermined timing within each displacement step of the one bar.
Claims19
Warp knitting machine having at least one bar mounted to reciprocate through displacement steps in accordance with a predetermined schedule, a main shaft, and means comprising:
- an electrically activated drive arrangement having a body made of a material which alters at least one dimension in dependence upon an applied field magnitude;
- and
- a control arrangement coupled to said drive arrangement for providing thereto, in accordance with said predetermined schedule and in dependence upon angular displacement of the main shaft, an electrical signal for establishing said applied field with a predetermined timing within each displacement step of said one bar.
