Method of extruding plastic materials.

摘要

The invention relates to an apparatus for extruding plastic materials, in particular for extruding foam plastics, which is equipped with a calibrating device, which has at least one take-off for the plastics material and at least one calibrating die or unit, and is provided with a calibrating table as well as with a device for controlling the take-off rate of the plastics material, the invention providing that there is arranged upstream of the take-off a device for measuring a foam internal pressure which outputs measured values which are used for controlling the take-off rate of the plastics material.
