Abstract

Nozzle for producing tubular thermoplastic profiles between a fixed mandrel and a sleeve clamped against the outlet end of the injection barrel. The sleeve is supported by rollers between tracks on the sleeve and its clamping cage resp. Roller support reduces the friction inhibiting adjustment of the extrudate concentricity w.r.t. the mandrel, allowing simple threaded thrust bolts to be used instead of more powerful pneumatic or hydraulic systems to adjust the extrudate concentricity.
