Patent ID: 7691303

Claim:
A method of manufacturing a projections-seating base member in which plural projections are formed in a spaced arrangement on a first surface or a second surface of a base member or on both said first surface and said second surface, said method comprising: preparing said base member; preparing a metal mold which comprises a reference surface and plural projection-shaping die parts, said plural projection-shaping die parts having ring-like protruding sections projecting from said reference surface and surrounding hollow spaces which are shaped to match with the profiles of said projections; placing a thermoplastic or thermosetting sheet-like molding material on said base member; pressing said metal mold against said molding material placed on said base member and pressurizing said molding material at least with said ring-like protruding sections without cutting said molding material, so as to bond portions of said molding material which are pressurized with said ring-like protruding sections to said base member, and so as to form and shape said projections from said molding material which is opposed against the insides of said hollow spaces surrounded by said ring-like protruding sections; and leaving on said base member said molding material which is opposed against said plural projection-shaping die parts and stripping off said molding material other than said molding material which is opposed against said plural projection-shaping die parts.
