<p>PURPOSE:To enable the efficient production of a spigot in wide thickness, by a method wherein a mold for a spigot, inserted into an end of a composite straight pipe, is caused to turn together with the pipe, and a mixture of curing resin and a filler is fed between the mold and a molding roll for molding the outer wall of the pipe end to be molded thereat. CONSTITUTION:Rotary shaft of retainers 1 and 2 turn a composite straight pipe 7 in a condition to insert a forward end part 5a of a mold 5 for a spigot into an end 7a of the composite pipe 7. A molding roll 8 is positioned outside the pipe end 7a and on a rotary shaft 9. A mixture of curing resin and a filler is supplied in each constant amount into a space between a staged part 5b of the mold 5 for spigot, wherearound a fibrous reinforcing material 12 soaked with the curing resin is wound, and the molding roll 8, and is wound in a uniform thickness around a reinforcing layer to form a pipe end part.</p> |
