PURPOSE:To enhance bonding strength by mounting the second bonding body capable of relatively approaching and separating with respect to the first bonding body and drawing both ends of the strip like member wound around a molding drum near to each other on a slit when approaching the first bonding body to bond the same in an abutted state. CONSTITUTION:At first, a strip like member K is wound around the cylindrical part of a molding drum 47 but, at this time, a slight gap S is left between both ends of the strip like member and superposed on the slit of the cylindrical part. Next, the first and second bonding bodies 58, 81 are allowed to approach each other to draw both ends of the strip like members near to each other on the slit to mutually bond the same in an abutted state. Herein, since the first bonding body 58 is arranged inside the molding drum 47, and the second bonding body 81 is arranged outside the molding drum 47, the inner and outer surface parts of the strip like member are respectively drawn near by the first and second bonding bodies and both ends of the strip like member are certainly and strongly bonded on the molding drum. |
