Apparatus and method for continuously producing reinforced plastic pipe using transfer film

An apparatus for continuously manufacturing a reinforced plastic pipe using a transfer film, the apparatus being capable of winding an outer circumferential surface of a rotating base mold with a resin-impregnated glass fiber depending on a filament winding method and hardening the same to continuously manufacture a reinforced plastic pipe to a predetermined length depending on setting, the apparatus comprising:

• a shaft tube configured to have a certain length and a hollow tubular shape, front and rear ends of which are opened, supported by a frame part, and configured to rotate at a rotational speed depending on setting by a driving part;
• a base mold configured to have a tubular shape having an outer circumferential surface of any one of a variety of cross-sectional shapes comprising a circle, a polygon and an oval and to rotate integrally with the shaft tube with respect to the shaft tube as a central axis;
• a transfer film supply part configured to rotate in the same manner as the shaft tube while supplying a transfer film that covers a longitudinal outer circumferential surface of the base mold and winds the longitudinal outer circumferential surface in close contact therewith from the rear to the front, wherein an end of the transfer film in close contact in the front is introduced into an opened hollow on a front end side of the shaft tube from a front edge of the base mold and passes through a rear end of the shaft tube;
• and
• a transfer film draw-out part disposed in the rear of the shaft tube and configured to grasp an end of the transfer film, which has passed through the hollow, and to forcibly withdraw the same backward at a speed depending on setting so as to move the transfer film in close contact with the outer circumferential surface of the base mold forward at a speed depending on setting,
• wherein the reinforced plastic pipe is continuously manufactured while moving the reinforced plastic pipe, which is wound and molded on a film, forward according to forward movement of the transfer film in close contact with the outer circumferential surface of the base mold.
