PURPOSE:To easily obtain a long continuous pipe by providing plural driving devices capable of giving rotation synchronized with an extruder to a synthetic resin spiral pipe sent out while hot-bonding and turning the side edge portions of a synthetic resin strip. CONSTITUTION:A material 3 extruded through the die 4 of an extruder is directed onto a cantilever beam 2 fixed to a fixing base 1 and also the side edge portion of a spiral pipe being turned and the side edge portion along is hot-bonded 10. The synthetic resin spiral pipe is gradually cooled and made into a long resin pipe of a length of 500m or 100m by using a simple system in which the amount of the material extruded from the extruder is synchronized with the turning parts of a takeover, turning type caterpiller capstan 7 and also of a necessary number of driving devices 8 and 9 provided behind the caterpiller capstan 7 and capable of giving a rotation to the synthetic resin spiral pipe to a length of every 10m, for example. |
