Abstract
A method for producing a multi-layered hose by electrostatically applying a thin resin layer on the inner surface of a tubular rubber outer layer. The resin can be applied by spraying resin powder from a bar nozzle inserted into an opening of the tubular outer layer, and the applied resin can be heated by an induction or dielectric heating source placed inside the tubular outer layer. The resin can be applied only to the hose body portion and not to edge portions which are to be attached to mating pipes, or a thinner layer of resin can be applied on the edge portions than on the body portion. An intermediate layer containing dielectric material or at least one of electrically conductive and magnetic material can be formed between the tubular outer layer and resin inner layer.
