Method of and device for controlling fabric take-up in circular knitting machine

摘要

A take-up control device (6) includes a control mode setting means (11) capable of setting a control mode for a take-up servo motor (5) to one of a torque control mode, under which the take-up servo motor (5) is driven so as to maintain a winding tension of the knitted fabric at a constant value, and a position control mode, under which the take-up servo motor (5) is driven at a constant angle of rotation relative to revolutions in the knitting unit (2). This take-up control device (6) is operable to initiate the take-up of the knitted fabric under the torque control mode and to shift the control mode from the torque control mode to the position control mode, after a take-up condition under the torque control mode is determined as stabilized by a stabilization determining means (15), to perform an automatic take-up of the knitted fabric.
