ABSTRACT:
A weft thread insertion arrangement for the weft thread magazine of a warp knitting machine has a warp thread laying insert carriage. The carriage, in conjunction and cooperation with the main shaft of the warp knitting machine, is driven between two forwarding devices for forwarding the laid weft threads to a needle bed. The arrangement has a drive assembly including a computer and a servomotor. The computer has at least one data storage device for taking up the data associated with at least one movement path formula. A sensor is provided for determining the number of revolutions and the angular displacement position data of the main shaft, which is fed back to the computer to enable it to compute the required drive speed of the servomotor.
