Abstract

PURPOSE: To uniformly vulcanize an inner and an outer layer and to shorten a vulcanizing period, by a method wherein the inner layer is pre-vulcanized previously before the outer layer is extruded and coated, where a laminated rubber long object consisting of a plurality of the inner layers and other layers is vulcanized continuously.
CONSTITUTION: Unvulcanized rubber is extruded to an outer circumference of a mandrel 2 to form an inner layer 3, a wicker work coating of steel wire being applied to an outer circumference of the inner layer. A wickerwork-coated unvulcanized rubber formed object 13 is fed to a pre-vulcanizing device 7 whereat it is pre- vulcanized by overheated steam fed through a charging port. A pre-vulcanized rubber 11 is coated on an outer circumference thereof to form an outer layer 5. The resultant product is fed to the vulcanizing device where the outer layer 5 and the inner layer 3 are vulcanized completely. Afterwards, the work is solidified by cooling.
