PURPOSE:To provide a continuous valcanizing device for a valcanized rubber sheet, by which the quantity of the valcanized rubber sheet to be scrapped is reduced by making a pitch, by which a pattern of the joint part of a carrying belt is transferred periodically on the surface of the rubber sheet, longer. CONSTITUTION:A continuous valcanizing device 1 continuously valcanizes a waterproof sheet in such a manner that an un-valcanized rubber sheet 7 is put on a belt 3 for carrying, and is made to pass through the inside of a valcanizing can 2. The continuous valcanizing device 1 consists of the valcanizing can 2, the endless form carrying belt 3 which continuously circulate- moves between the inside and outside of the valcanizing can 2, a winding/ rewinding member 5 comprising a drum to take up the moving endless form carrying belt 3 while doubly overlapping, and a drum to rewind the endless form carrying belt 3, and a moving member 6 which brings the endless form carrying belt 3 into contact with one of the drums to assist the double winding. |
