Abstract
In a system for controlling a puller assembly (3) for withdrawing an extruded section as it exits from an extruder, in which the puller assembly (3) is moved in withdrawing direction by means of a drive mechanism (9), the actual speed with which the extruded section (1) is withdrawn is sensed by means of a tachometer (34) and is delivered to a speed controller (32) for controlling the speed of the drive mechanism (9) for the puller assembly. Optimum pulling force may be adjusted by providing follower means (11, 12) between the puller assembly (3) and the drive mechanism (9), said follower means being acted on by an actuator (15) for permitting relative movement between a drive member (8) and the puller assembly. The relative movement of a follower (11) is delivered via a displacement detector (30) to the speed controller (32) as a disturbance factor.
