A method and a mould for blow-moulding hollow bodies, such as pipes, provided with integral pre-fabricated annular bodies, such as end flanges (6, 7), pipe attachments (8) and reinforcement tubes (9), according to which the bodies are positioned inside a passage (3) in the mould (4). The tubular melt (2) is lowered from the extruder (10) down into the passage (3), and thus also through the annular bodies (6-9) therein, whereupon the melt is blow-moulded inside the passage. |
