  • Patent number: 4053343
    Abstract: In a continuous method of making pipe from fiber elements coated with a thermosetting resin, the coated fiber elements are wrapped around a resin saturated conveyor tube which becomes an integral part of the finished pipe assembly. The method of manufacture employs a first mandrel section and a second mandrel section in alignment therewith and longitudinally spaced therefrom by a gap. A tube of resin-absorbent material is applied to the first mandrel section, a thermosetting resin is applied to the tube as it passes over the gap in an amount sufficient to saturate the tube. The resin is at least partially cured prior to its arrival onto the second mandrel section where it provides the conveyor tube for the application thereto of a plurality of bands of continuous fiber elements coated with a thermosetting resin composition.
