  • Patent number: 9393717
    Abstract: In a processing plant for producing plastics material granulate, the start-up takes place in such a way that a screw machine is firstly driven by means of a drive device and then plastics material to be processed is fed by means of a metering device into the screw machine. At least one conveying position of the plastics material in the screw machine is determined by means of a control device by evaluating at least one measuring signal. Depending on the conveying position determined, a granulating device is activated and put into operation. The method according to the invention allows a direct start-up of the processing plant without the use of a start-up valve. This ensures an easy and safe start-up of the processing plant.

  • Patent number: 7004743
    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.
