Abstract
An attachment for a warp knitting machine is disclosed. The attachment produces a patterned effect on fabric knitted by the warp knitting machine. The warp knitting machine includes at least one warp beam, a thread separating mechanism, a knitting mechanism, and a first tensioning mechanism positioned between the warp beam and the knitting mechanism. The attachment includes a moveable supplemental tensioning mechanism operatively connected to the knitting machine for cyclically varying the tension on first and second groups of threads disposed on opposite sides of the supplemental tensioning mechanism. A mechanism is provided for cyclically moving the supplemental tensioning mechanism in first and second directions about a neutral position to alternately tension the first and second groups of threads.
