PROCESS FOR PRODUCING RUBBER TUBE AND RESIN COATING DEVICE USED THEREIN

摘要

This invention relates to a process and a device for producing a rubber tube. It is the subject of this invention to provide a process and a device for efficiently producing a rubber tube having a smooth outside surface, and this subject is achieved by a process and a device characterized in that a molten synthetic resin is heated from the inner circumferential side immediately before it flows from a die along the periphery of a rubber material layer. This invention can be used for the efficient production of a rubber tube having a smooth outside surface.
