Abstract

Designed for a screw press to polymerise rubber mixtures, in conjunction with a vacuum chamber, an adjustable ring space is provided at the point where the diameter of the screw increases on entering the vacuum chamber zone. The purpose is to prevent material dwelling in the space and vulcanising when the screw press is stopped and to allow adjustment according to the degree of plasticity required.
