PROBLEM TO BE SOLVED: To shorten the production cycle by forming a connecting part in the final adhesion process following a temporary sticking process or in the process of blanking after the completion of the final adhesion process. SOLUTION: To stick and fix a friction material to the upper surfaces of a large core plate 1 and a small core plate 2, an adhesive for final adhesion is applied, and after the adhesive is dried, an adhesive for temporary adhesion is applied [process (A)]. Secondly, a friction material segment 4 for the small core plate 2 and a friction material segment 6 for a large core plate 1 are blanked from a friction material tape 3 and pressurized by a pressing device to perform temporary adhesion [process (B)]. Heat and pressure are simultaneously applied to the product where temporary adhesion is completed by a final adhesion device to perform final adhesion of the friction material to the core plate [process (C)]. Lastly, in the process (D), after the end of final adhesion, a connecting part 5 is blanked by a punch so that the large core plate 1 and the small core plate 2 are formed and separated as two kinds of friction plates different in diameter to which the friction material is stuck. |
