Flexible reinforced hose is manufactured by applying about a support mandrel (10) at least one layer (12,13)(for 13 - figure 4 (not shown) of plastics material and at least one layer (12,14) of reinforcement material and then subjecting the assembly so formed to a hot moulding process to increase the temperature of the plastics material whereby in the finished product a bond is achieved between component layers in consequence of said hot moulding process. The hose may be used as a suction hose wherein a helically extending metallic structure is embedded in a layer of plastics material. A helically extending high modulus plastics reinforcing structure may be embedded in a layer of plastic material to form the flexible hose. |
