Device for processing rubber mixtures, has flow channels, where respective flow channel has channel constriction before entry in end channel, where foreign bodies are restrained in channel constriction

摘要

The device has two flow channels (1), where the respective flow channel has a channel constriction (11,12) before entry in an end channel. The foreign bodies (10) are restrained in the channel constriction. The height dimension (H1) of the channel constriction amounts to 0.5 to 2 millimeters. The height dimension corresponds to the diameter of conventional foreign bodies occurring in rubber compounds.
