Abstract

This describes a fabric take-down device (11) for flat knitting machines which is provided with a driving motor (12) and an associated adjusting device (13) to set the torque of the driving motor (12) which determines the take-down pull through the motor current. In order to provide in a fabric take-down arrangement (11) of this character for a substantial starting and controlled pull, and in particular to cater for a finely-sensitized regulation even in the area of small torque values, provision is made for the adjusting device (11) to be constituted by a motor-current regulating system (26) which is provided with inputs (27, 28, 33, 34, 39) for setting the target figures and for at least one actual value taken from the driving motor (12), and the regulating system (26) further has an input (32) for an augmenting shift pulse for a short-term increase in the torque of the driving motor (12) where there is a small target tongue (FIG. 1).
