Abstract
The present invention provides a patterning unit of a warp knitting machine having a holding member with a stator of a linear pulse motor disposed thereon and a plurality of moving elements provided at arbitrary intervals on the holding member with parts of the moving elements being constructed as guide points. A control method increases reliability and accuracy of positioning the moving elements and eliminates erroneous operation such as step-out by providing a position sensor and by exciting movement of the moving elements on a step by step basis based upon positions of the moving elements sensed by the position sensor. The control method includes providing the moving elements each with a linear motor coil assembly for functioning in conjunction with the stator to move the moving elements along the holding member.
