Abstract
A core plate, which has been punched in a core plate punching step, is conducted a surface roughing stepand a cleaning step. After coating both surfaces of the core platewith adhesive in an adhesive coating step, the core plateis put on a friction member, which has been punched in a friction member punching step, in a piling step, and a piled bodyis conveyed to a drying and curing step. The core plateis heated by high-frequency heating to dry and cure the adhesive. The core plateand the friction memberare heated and pressured by the hot press, and the friction plateis completed. Since high-frequency heating is adopted, an apparatus can be downsized, working time can be reduced and production efficiency can be enhanced.
