Abstract

Improvements in the extrusion processes of bars and profiles of thermoplastic materials, with areas of different density section, these areas of different density being arranged around each other, in juxtaposed or superimposed form, using a foamable plastic and an expanding agent, which is essentially characterized in that the plastic stream sometimes divides into at least two partial streams and joins again before foaming, heating at least one of the partial streams up to or above the evaporating temperature of the expanding agent and the other or the other partial streams being maintained at a temperature below the evaporating temperature of the blowing agent.
