Abstract

A fabric take-up apparatus for a circular knitting machine includes a set of delivery rolls for flattening and delivering the flattened fabric to take-up means which winds the flattened fabric into a roll, sensing means for sensing the tension in the fabric and for generating electrical signals indicative of fluctuations in tension from a predetermined, desired tension in the fabric, variable speed drive means for driving the delivery rolls, and control means for controlling the variable speed drive means responsive to the electrical signals generated by the tension sensing means.
