Method and device for measuring at least one physical characteristic of the extruded product on a continuous extrusion machine in operation

摘要

This method is of the type employing means 12 altering one of the operating parameters and means 14 processing data coming from the measurement means. The method consists in temporarily interrupting the feeding of a hopper 15 in which a store of raw material is formed, in measuring during the aforementioned interruption, on the one hand, the variation in the weight of the material flowing through the hopper and, on the other hand, at least the linear speed of the product 4 being extruded, and in employing the result of these measurements to determine an operating characteristic and accordingly alter the operation of the extruder.
