Abstract
A method for manufacturing a friction plate in which a plurality of frictional material segments are adhered to a substantially annular core plate. The method previously registers the frictional material segments to adhesion positions, and presses the core plate to which adhesive agent is applied and the frictional segments to perform temporary adhesion. Further, an apparatus for manufacturing a friction plate in which a plurality of frictional material segments are adhered to a substantially annular core plate. The apparatus comprises a member for registering the frictional material segments while holding the frictional material segments in a state arranged in the adhesion positions.
