ABSTRACT:
A process for producing a clutch friction plate in which a plurality of friction material segments are bonded to an annular flat face of an annular core plate so that oil channels are formed between the segments, the process including: a step of forming a plurality of strip-shaped friction materials by cutting a band-shaped friction material along its longitudinal direction; a step of aligning and holding portions, corresponding to the segments, of leading edge parts of the materials in positions above the core plate while positioning the portions in the peripheral direction and in the direction along one diameter of the core plate; a step of forming the segments by cutting off the leading edge parts of the materials positioned above the core plate along a cutting-off line that includes at least an arc line that follows the outer periphery of the core plate, and a step of pressing and bonding the segments onto the face coated with an adhesive.
