Method and apparatus for adjusting the stitch length on a circular knitting machine.

摘要

A method of and circular knitting machine (20) for producing a knit fabric having more uniform stitches including yarn feeders (76) feeding a plurality of yarns (Y) to stitch forming instrumentalities, the spacing of which affects stitch length and which is subject to change during operation of the knitting machine, a sensor (86) for sensing the tension in the plurality of yarns which changes with changes in the spacing of the stitch forming instrumentalities, and generating a signal indicative of the average tension in the yarns, a comparator for comparing the sensor signal with a pre-set desired tension, a convertor for converting the comparison result into a drive signal, and an adjuster adjusting the spacing of the stitch forming instrumentalities responsive to the drive signal. <IMAGE>
