Multi-component nozzle for merging at least one flowable additive component with at least two flowable, plastics-forming, especially foam-forming, main components in order to initiate the reaction by mixing

摘要

For the merging of at least one flowable additive component with at least two flowable plastics-forming, especially foam-forming, main components in order to initiate the reaction by mixing, a multi-component nozzle having a central valve pin (57) and a coaxial pin sleeve (62) is used, the feed of the additive component being controlled by means of the valve pin (57).
