ABSTRACT:
A pull measuring system used in a puller for extrusion profiles being extruded out of an extruder comprises a divided puller head (14) having its parts (30,31) supported for pivoting movement with respect to each other about an axis (32) which extends transversely of the direction of pull. In operation a tie bar (39) fixed to the part (31) carrying the clamping grippers for the extrusion profiles acts in the direction of pull on a force detector (34) fixed to the other part (30) which is arranged at a cantilever (13) of a carriage. In this manner the pull prevailing in operation and being transmitted by the puller to the extrusion profiles can be sensed reliably and accurately under any operating conditions.
