Method and machine for producing a single-walled or multi-walled tubular thermoplastic body

Method and machine for producing a single-walled or multi-walled tubular thermoplastic body

The invention relates to a method for producing at least one single-walled tubular thermoplastic body in a machine (10), a nozzle head (12) extruding at least one tubular preform (14). Said preform (14) is expanded to a predefined dimension in a transverse direction and to a predefined shape in an e...

Zusammenfassung:The invention relates to a method for producing at least one single-walled tubular thermoplastic body in a machine (10), a nozzle head (12) extruding at least one tubular preform (14). Said preform (14) is expanded to a predefined dimension in a transverse direction and to a predefined shape in an expansion process using an expanding mandrel (16), the preform (14) remaining open at the top and bottom. When the at least one preform (14) has cooled off, the expanding mandrel (16) is changed into a non-expanded state and the at least single-walled tubular body is removed from the machine (10).
