Abstract
The Raschel machine is provided with locking belts which are fixed relative to a plane perpendicular to the shogging motion. In addition, the yarn laying-in comb and at least one guide bar for the stitch yarns are movable not only in a plane perpendicular to the shogging direction but also in a plane parallel to the shogging direction. The motion of the laying-in comb allows large underlaps without risk of faulty lapping of the yarns.
Claims4
A Raschel warp knitting machine comprising
- a plurality of needles;
- a plurality of parallel lapping belts for guiding pattern yarns to said needles;
- first means for selectively shogging said belts in a shogging direction parallel to said belts;
- a yarn laying-in comb for laying the pattern yarns into said needles, and comb being mounted for orbital motion perpendicular to said shogging direction;
- at least one guide bar having needle guides for guiding stitch yarns to said needles, said guide bar being mounted for oscillation perpendicular to said shogging direction;
- and
- means for driving said comb for a uniform selectable shogging distance in said shogging direction.
