  • Patent number: 9440374
    Abstract: The invention relates to a device (1) for producing polymer agglomerates, comprising a compounder (2) having a housing (21) and a twin screw (22) arranged therein as well as a plurality of material inlets (3, 4) for admission of a polymer and additives, tempering units for heating the mix comprising polymer and additives, at least one degassing unit (5) and an outlet (23) and an agglomerating vessel (11) having an agglomerating tool (8) and a cooling tool (10). The agglomerating vessel (11) is connected via a connection channel (6) to the outlet (23) of the compounder (2), wherein the twin screw (22) of the compounder (2) is designed as a co-rotating twin Screw (22) and the agglomerating tool (8) of the agglomerating vessel (11) is arranged in the fall direction of the mix below the connection channel (6) and comprises mutually engaging rotors (81) and stators (82) for producing agglomerates of defined particle size. The invention further relates to a method for producing polymer agglomerates.

  • Patent number: 5067312
    Abstract: In a device for packaging objects in stretch film, the film (3) intersects the supporting face determined by the conveyor track (1), and the conveyor track (1) is at least partially of a width which is smaller than that of the objects (2) to be packed, in such a way that the latter project at the longitudinal sides relative to the conveyor track (1) and the part of the film situated below the supporting face can wrap around the bottom longitudinal edges against and on the edge areas of the bottom side of the objects to be packed.
