Abstract

An installation for the treatment and further processing of thermoplastics comprises a screw-type compounding unit, downstream of which is disposed an intermittently drivable processing unit. Provision is made for a control unit which is connected with a drive of the screw-type compounding unit and with the drive of a metering device and with a drive of the processing unit. The control unit is designed for triggering the drives by the cycle time of the processing unit, the drives having identical run-up times and identical deceleration times.
