Fabric winding device for a circular knitting machine.

摘要

Two nip rolls (2, 3) are mounted between two arms of a stirrup (17) articulated about an axis (18) integral with a second stirrup (21) articulated about an axis (22). Said rolls are given by a motor (25) and the knitted fabric is rolled about a winding bar (4) driven by a motor (14). Two force sensors (28, 29) measure respectively the tension exerted by the knitted fabric (1) between the roll (3) and the bar (4) via the stirrup (21) articulated about the axis (22) and the tension exerted by the knitted fabric (1) between the roll (2) and the knitting machine needles via the stirrup (17) articulated about the axis (18). As the tensions of the knitted fabric are merged with the axes (18, 22), the tensions applied to those axes do not generate any torque to the levers articulated to said respective axes so that the motors (14, 25) set by the sensors (28, 29) adjust independently the tensions in the knitted fabric ends upstream and downstream of the rolls (2, 3).
