ABSTRACT:
A draw-roll assembly is movable downwardly on guide rods from a working position into a filament take-up position. A slightly heavier counter weight connected with the draw-roll assembly by means of a cable ensures that the draw-roll assembly stays in the upper position even upon failure of a pneumatic control and also that the movement forces are limited substantially to the difference between the weights. An electro-pneumatic control controls the movement speed of the draw-roll assembly from the filament take up position into the working position.
