The invention relates to a method for producing a textile sheet heating element (1), wherein a warp-knit is formed and in one and the same operation, heating conductors (4) are laid as warp threads by warp-knitting. At intervals from one another, contact conductors (5) that touch the heating conductors (4) are introduced as weft threads or weft thread groups. In order to produce the sheet heating element (1), use is made of a warp-knitting machine or Raschel machine, the production rate of which is varied depending on the loop formation. The warp-knitting machine or Raschel machine has a magazine weft insertion system having feed chains (11) for feeding weft threads and a weft carriage (12) for inserting weft threads. Both the feed chain (11) and the weft carriage (2) are stopped for predetermined times depending on the loop formation.
