Abstract
A method for producing a textile sheet heating element includes forming a knitted material and, in one and the same work step, inserting heat conductors as warp threads. Contact conductors that touch the heat conductors are inserted spaced from one another as weft threads or weft thread groups. A warp knitting machine or Raschel machine is used to produce the sheet heating element. The production speed of the knitting or Raschel machine is varied as a function of stitch formation. The warp knitting machine or Raschel machine has a magazine weft insertion system with feeding chains to feed in weft threads and a weft carriage to insert weft threads. Both the feeding chain and the weft carriage are paused for preset periods as a function of stitch formation.
Claims16
A method to produce a textile sheet heating element, comprising:
- forming a knitted material and, in one in the same work step, inserting heat conductors as warp threads in a knitting process and inserting contact conductors that touch the heat conductors at spacings from one another as weft threads or weft thread groups;
- using a warp knitting machine or Raschel machine to produce the sheet heating element and varying a production speed of the warp knitting machine or Raschel machine as a function of stitch formation and, wherein the warp knitting machine or Raschel machine has a magazine weft insertion system with feeding chains to feed in weft threads and a weft carriage to insert weft threads;
- and
- pausing both the feeding chain and the weft carriage for preset times as a function of stitch formation.
A magazine weft insertion system for a warp knitting machine or Raschel machine for use in a knitting process to make a knitted material, comprising:
- feeding chains to feed in weft threads and a weft carriage to insert weft threads in a knitted material;
- and
- a control unit to pause the weft carriage and the feeding chains for preset times during the knitting process as a function of stitch formation in the knitted material.
