摘要

The roto-welding of e.g. a synthetic tube in a roto-forming mold has synthetic material introduced into the mold, for roto-molding with simultaneous fusion of the main container and the outer wall of the tube or of an auxiliary container in the mold. This integrates the contacting zones simultaneously with formation of the inner walls of the main container.
