PULL MEASURING SYSTEM IN A PULLER FOR EXTRUSION PROFILES EXTRUDED OUT OF AN EXTRUDER

摘要

A pull measuring system used in a puller for extrusion profiles being extruded out of an extruder comprises a divided puller head having its parts supported for pivoting movement with respect to each other about an axis which extends transversely of the direction of pull. In operation a tie bar fixed to the part carrying the clamping grippers for the extrusion profiles acts in the direction of pull on a force detector fixed to the other part which is arranged at a cantilever 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.
