Abstract
The invention relates to a warp knitting loom with individually driven guide bars that are controlled by a control device. A linear motor is used, resulting in a particularly space-saving and flexible driving apparatus. This motor has at least two driving elements which are each connected to a guide bar and can move back and forth in a common stator with a closed magnetic circuit. Each driving element has at least one drive coil which is connected to the control device and whose winding plane is transversal to the magnetic flux.
Claims11
A warp knitting machine, comprising:
- at least two individually driven guide bars each moveable back and forth in a predetermined direction of movement;
- an electronically controllable linear motor having at least two drive members, each drive member being connected to a respective guide bar, and a common stator having a closed magnetic circuit for guiding the drive members back and forth, the magnetic circuit defining a magnetic flux direction;
- at least two drive coils located in said stator, each drive coil being associated with a respective one of said drive members, the drive coils each having a plane of turn oriented transversely to the magnetic flux direction;
- and
- a control device for controlling movement of said guide bars, the control device being connected to said drive coils to control said guide bar movement.
