Abstract:
1. A method for the manufacture of a molding composition from a raw material melt which is charged with an additive including the steps of plasticising a flow of a raw material selected from the group consisting of a liquid composition, a viscous liquid composition, a gooey pasty composition, a granulate and an elastomer strip within a cylinder of a conveyor apparatus containing at least one of a rotating screw and a reciprocating screw into a raw material melt; passing the melt through a passage section arranged inside the cylinder and disposed downstream of the screw; metering an additive through a plurality of metering elements placed in the passage section wherein the step of metering the additive includes passing the additive from a supply passage through an annular passage extending between the cylinder and the passage section and in communication with the metering elements for metering of the additive from the annular passage into the raw material melt through the metering elements, and wherein each metering element of the plurality of metering elements is arranged in a spaced apart relationship to a neighboring metering element of the plurality of metering elements such that the plurality of metering elements are distributed around the periphery of the passage section; mixing of the raw material melt with the additive subsequent to said step of metering to produce a molding composition, with the molding composition being present as a homogeneous mixture of the raw material melt with the additive; and discharging of the molding composition from the conveyor apparatus.
