Abstract

A flat knitting machine includes a device for adjusting the retractor elets for the needles in the cam systems on the carriage of the machine for the setting of the stitch tension. In order to simplify the tension adjusting mechanism and simultaneously to produce a sensitive setting mechanism, there is provided on the carriage a single electrical stepping motor, with position sensor, for counterbalanced adjustment of the leading and of the trailing retractor elements of each cam system.
