ABSTRACT:
A treatment apparatus for a textile material e.g. a wet tow, has a machine with guide rolls arranged in two rows for the meander-like guidance of the endless textile material. In order to obtain uniform material tension at each of the, for example, top guide rolls, these are not only electrically driven individually but also are subjected to a specific torque, determined by measuring the actual longitudinal tension in the length of material at, for example, the first and last guide rolls, by electronic comparison of the measured data, and by utilization of the positive or negative measuring result for controlling the torque of the incorrectly turning guide roll.
