ABSTRACT:
In the production of profiles from rubber and/or plastic mixtures, the throughput of the extruder should be kept constant. To this end, an identification of the mixture of material to be processed is fed in the form of a code to a computer system in which the characteristic mixture properties and the set-point operating values for a given profile to be made by the extruder are stored in memory. During the extrusion process, at least one operating variable, preferably the pressure occurring in the mixture of material being processed, is measured continuously, the difference between a measured value at a given time and the corresponding set-point value of the operating variable stored in memory is formed, and this difference is used as a control variable for a governing system for the speed or rpm of the extruder which is operated by the computer system.
