摘要

Improvements in heating means of extrusion machines of synthetic thermoplastic resins, essentially characterized by subjecting the heating tube that constitutes the indicated means, to an alternative thermal regime, considered in the forward direction of the thermoplastic material inside, of heat receiving phases, that is, in which the heating resistors supply heat to the pipe, and other phases of heat transfer, in which said pipe is the one that gives heat to the external environment.
