Abstract
Process and apparatus for fabricating a pneumatic rubber fender comprising a cylindrical body of a combination of a plurality of rubber and reinforced rubber layers, both of the terminal ends of which are closed so that compressed air can be sealed therein. In the fabrication process, the cylindrical body of a non-vulcanized rubber fender, one end of which is closed by a first end plate, is firstly formed on a fabrication drum provided with a cylindrical portion and an end plate portion closing one end of the cylindrical portion. The connection of a second end plate with an opened free end of the above-mentioned cylindrical body of the non-vulcanized rubber fender is carried out in such a condition that the above-mentioned opened free end is turned back while the cylindrical body of the non-vulcanized rubber fender is mounted on the fabrication drum. After completion of the above-mentioned connecting operation, the non-vulcanized rubber fender is withdrawn from the fabrication drum and thereafter subjected to the vulcanizing operation.
