Abstract (en)

The present invention provides a take-up control method and a take-up control device both for use in an electronic pattern knitting machine, which are effective to automatically perform take-up of the knitted fabric under a proper, and stabilized take-up tension even though the pattern of the knitted fabric is changed, in which by means of a take-up control unit (6), a control mode of a take-up servo motor (5) is settable to one of modes including a torque control mode, in which the take-up servo motor (5) is rotated so that a take-up tension of the knitted fabric may be constant, and a position control mode in which the take-up servo motor 5 is rotated at a certain angle of rotation relative to the rotation of the knitting unit (2), and, in the event that a change is made to a second pattern while the knitted fabric having a first pattern is being produced under the position control mode, the position control mode is automatically switched over to the torque control mode to enable a knitted fabric having the second pattern, changed under the torque control mode, to be automatically performed.
