<p>PURPOSE:To enable to connect stably a sealing gasket by contriving strengthening of bonding force, by a method wherein an annular piece is arranged at a predetermined position of the inside of a revolving frame, a fibrous reinforcement and a synthetic resin binder are supplied while the frame is being revolved, and simultaneously with removal of an air bubble those materials are clamped and cured for formation. CONSTITUTION:A plurality of pieces of annular pieces 2 is arranged on an appropriate position of the inner circumference of a tubular frame 1. A resin tank 9, a resin carrier 10 and a glass bobbin 11 are mounted on a truck 8. The truck 8 performs reciprocating motion. When the frame 1 arrives at a predetermined revolving speed by a revolving wheel 4, resin is fed to a resin blow-off port 5 from the resin tank 9 through piping 12 by the resin carrier 10, and on the other hand, glass fiber is led to a roving cutter 6 from the bobbin 11, both of which are supplied within the frame 1 and a glass fiber.resin mixture 15 accumulated on the inside of the frame 1 is formed. Removal of an air bubble from an accumulated layer is performed through centrifugal force and at the same time clamping and curing are performed. With this construction, in case of application of the titled method to a coupling of a Hume concrete pipe for build-up, a protrusion piece for reinforcement of bonding force and a protrusion ring for connection of a gasket for sealing can be provided unitarily.</p> |
