PROBLEM TO BE SOLVED: To improve a degree of freedom for a profile of an oil groove and a manufacturing yield for manufacturing of friction material segments when manufacturing friction plates of clutches by bonding a plurality of friction material segments so as to form oil grooves on a circular surface of a circular core plate. SOLUTION: A manufacturing method and system for friction plates of clutches comprises a process for forming a plurality of strip-shaped friction plates 22 and 23 by making a cut on a beltlike friction plate 21 along its longitudinal direction, a process for retaining sections corresponding to friction material segments 17 and 18 among heads of the strip-shaped friction materials 22 and 23 at an upper position of the circular core plate 16 while aligning the sections to a peripheral direction of the circular core plate 16 and a direction along one diameter line, a process for forming the friction material segments 17 and 18 by separating the head sections of the strip-shaped friction materials 22 and 23 stayed in a positioned state at an upper position of the circular core plate 16 with a cut-off line 24 including at least an arc line 24a along an outer periphery of the circular core plate 16, and a process for bonding a circular surface 16a in an applying state of a bonding agent by pushing the friction material segments 17 and 18.
