Abstract

In a continuous method of extruding fibre-reinforced, thermosetting resins, where the resin is hardened in the extrusion head, the material is fed forwards in such a way that no transmission of heat released in the thermosetting reaction takes place backwards along the material. In the preferred appts., a cooled zone is incorporated between the entry and exit portions of the extrusion head.
