Abstract

1,157,558. Profiled tubes. REIFENHAUSER K.G. 29 Aug., 1967 [23 May, 1967], No 39491/67. Heading B5A. Profiled thermoplastic tubes are continuously produced by extruding a tube 18 through nozzle 16 and conveying it between opposed die-halves 30 on endless chains 20, the nozzle having an extension 34 projecting into the diehalves and having plugs 40, 42 blocking the tube, there being a pressure line 60 in the extension opening into the dies between the plugs at 58, and the annular nozzle 16 being spaced from the dies. Plug 42 nearest the nozzle 16 may have a chamber 44 for circulation of coolant, supply line 52 and return line 50 running through the extension 34 for connection to a coolant circuit. The dies may be profiled to any desired shape e.g. having corrugations, longitudinal grooves, helical grooves, &c.
