Abstract

914,850. Extruding tubes. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. April 10, 1961 [April 12, 1960; Jan. 12, 1961], No. 12878/61. Class 87(2). Tubes of thermoplastic material extruded horizontally are internally cooled by direct contact with a cooling liquid supplied through an insulated duct passing through the mandrel of the die. In the die illustrated cooling liquid from insulated pipe 3 passes through holes 6 in interval sizing device 5 to contact the inner wall of extruded tube 7.
