ABSTRACT:
In a process and apparatus for producing TPE foam profiles, material is heated up in a conveying zone at a temperature of 180.degree.-210.degree. C. and a pressure of 100-200 bar. The melt then passes through a two-stage shear process consisting of two spaced shearing sections separated by a homogenizing section in which the melt and water are intimately mixed, with the melt being exposed to a further homogenizing section in which the melt is intensively mixed and homogenized prior to being extruded through a profile die.
