Abstract
A method and a device for joining rubber sheets. A pressing disk having a shape that a cutting disk is cut at an edge thereof by about 0.7 mm to 1.0 mm joins with pressure edge parts of unvulcanized rubber sheets which are stackably aligned with one another and clamped. The cutting disk cuts the joined edge parts of the rubber sheets. Another pressing disk having a shape that the edge of the cutting disk is cut by about 0.7 mm to 1.0 mm is moved on the cut edge parts along the cutting line in the same manner as the cutting disk, thereby securely joining the joined parts by pressing them again.
