Abstract

The impulse generators at the variable speed drives for the warp beams provide signals for comparison with the impulse generator at the main drive to determine how much yarn is to be drawn by the warp beams according to the knitting cycle, with visual indications and manual setting. This controls the yarn length feed to give a consistent fabric quality and yarn tension.
