US 5,675,993 A · Patterning method and device in warp knitting machine

Abstract

A patterning method and device has yarn guides for guiding pattern yarns in a warp knitting machine and divisional fall plates for knitting pattern yarns in a fall plate structure individually drive-controlled through drive devices. The device comprises any number of moveable bodies having yarn guides, the bodies being installed for movement along a row of knitting needles by the drive devices. For patterning, the moveable bodies are moved through a desired distance along the row of knitting needles so as to be positioned for patterning, thereby providing a patterning zone for pattern yarns corresponding to the number of yarn guides. Thus, it is possible to effect a free varigated patterning which is comparable with the patterning effect provided by the Jacquard control. Further, it possible to attain the knitting of a fall plate structure, in addition to the patterning by the aforesaid yarn guides, by moving any number of the moveable bodies having yarn guides and/or any number of moveable bodies having divisional fall plates by the drive devices to produce a fall plate-like action, without requiring a device of large scale.

Dependent claims

A patterning device for a warp knitting machine having a row of knitting needles, the patterning device comprising:

at least one moveable body;
a yarn guide mounted on each of said at least one movable body for introducing a pattern yarn to said row of knitting needles to perform patterning;
a holding member extending in a direction of said row of knitting needles slidably supporting said at least one moveable body for movement along said holding member, said holding member being disposed to support said at least one moveable body such that said yarn guide is cooperative with said row of knitting needles;
driving means for moving said movable bodies along said holding member, said driving means including a linear motor having a stator and a movable element moveable relative to said stator, said stator being mounted to one of said holding member and said at least one moveable body and said moveable element being one of mounted to and formed in another one of said moveable body and said holding member;
and
said at least one moveable body being moveable along said holding member by said driving means over a range of displacement, required for a pattern, by signals from a control section driving said linear motor.
