Abstract:
An apparatus for the continuous production of a twin wall pipe has mold block halves supplied in pairs to form a mold, and a pipe head, which has an external nozzle for the extrusion of an external hose and an internal nozzle for the extrusion of an internal hose. A support air and venting channel which is annular-cylindrical and concentric with respect to the center longitudinal axis of the pipe head opens out between the external nozzle and internal nozzle.
