THE CORRUGATE WINDS THE PROFLIE OF SPIRAL FORM IN THE PIPE AND THE PLASTIC PIPE FORMATION SYSTEM WHICH IT REINFORCES

摘要

A plastic pipe reinforced with a spiral type profile wound on a corrugate pipe is provided to mold an integral reinforced plastic pipe by supplying a spiral reinforced profile to a groove part. A plastic pipe reinforced with a spiral type profile wound on a corrugate pipe for evenly molding an inner diameter part(34) and spirally molding a projection part(32) and a groove part at the outside diameter comprises an extruder, a spiral profile molding device, and a reinforced plastic pipe. The extruder spirally supplies a reinforced profile(41) with an argyle type to a groove part. The spiral profile molding device spirally molds the reinforced profile with a spring and has a guide and a friction roller to supply the reinforced profile extruded from the extruder to a spring molder. The reinforced plastic pipe has the groove part and the reinforced profile integrally connected to a pipe molding device through a guide roller(43) from the outside diameter of the reinforced profile.
