Continuous production of insulating hose comprising outer protecting layer, inner gliding layer, and insulating middle layer, comprises extruding heat insulating foam hose. Hose is cut to form two parallel axial cut surfaces, and then spread flat. Inside of hose is supplied with gliding agent, and then it is fed back into hose mould. Cut surfaces are joined together. A process for the continuous production of an insulating hose comprising an outer protecting layer, an inner gliding layer, and an insulating middle layer, comprises extruding a heat insulating foam hose. The hose is cut to form two parallel axial cut surfaces, and is then spread out flat. The inside of the hose is supplied with a gliding agent, and then it is fed back into the hose mould. The cut surfaces are joined together and the outside of the hose is supplied with a seamless mantle layer. The gliding material contains reinforcing fibres and reflects infra-red radiation. |
