DEVICE FOR PRODUCING PIPES

摘要

The invention relates to a device (10) for producing pipes. Said device (10) comprises an extruder head (12) and a cooling mandrel (28) which is positioned downstream of the extruder head (12) in the direction of production of the pipes (arrow 30) and has vacuum grooves (36) embodied on its outer jacket surface (34). The vacuum grooves (36) are connected to a vacuum source (42) provided for at that end section (44) of the cooling mandrel (28) which is located downstream in the direction of production of the pipes (arrow 30). The extruder head (12) and cooling mandrel (28) house only a power supply line (48) for the vacuum source (42).
