Abstract:
A METHOD AND APPARATUS IS PROVIDED FOR CONTINUOUSLY MAKING FIBER REINFORCED PLASTIC PIPE IN WHICH A CONVEYOR TUBE IS FORMED ON AN AXIALLY FIXED HOLLOW ROTATABLE MANDREL. A PLURALITY OF BANKS OF RESIN IMPREGNATED FIBER ELEMENTS ARE WOUND ON THE CONVEYOR TUBE AS IT ADVANCES TO PROVIDE THE PIPE ASSEMBLY. THE TERMINAL END OF THE GENERATED PIPE ASSEMBLY IS SEALED WITH A PLUG. A FLUID UNDER
PRESSURE IS FED THROUGH THE HOLLOW MANDREL AND OUT THE FORWARD END OF THE MANDREL INTO A CHAMBER FORMED BY THE GENERATED PIPE ASSEMBLY, THE PLUG, AND A FLUID SEALING MEANS WITHIN THE PIPE ASSEMBLY BEING GENERATED, THEREBY CAUSING THE PIPE ASSEMBLY TO ADVANCE.
