Abstract
Device contains a source of polymer melting, a mixer connected with the unit of introduction of additives, which contains a source of fusion of additives, metering and pressuring gear pumps with drives and control system of the frequency of rotation by the drive of pressure pump with the sensor of pressure control in the melt conduit of additives. The metering pump is located upstream of the pressuring pump on the motion of the fusion of additives, and pressure sensor - at the outlet from the metering pump.
