Abstract

Procedure and apparatus for the manufacture of profiles of lightened thermoplastic materials, of any shape, including complex shapes, the procedure characterized in that it consists, immediately after leaving a conventional extrusion machine, of delaying and/or paralyzing the expansion in areas determined by blowing or spraying, in the periphery of the extrudate, differentially, a fluid at a temperature lower than the softening temperature of the thermoplastic material.
