PURPOSE:To obtain economically the title friction disc having oil grooves as deep as the thickness of the friction material and being high in the yield of friction material, by bonding friction material segments obtained by consecutively cutting a friction material tape to a core plate one by one. CONSTITUTION:An annular core plate 2 with its bonding face (a) being directed upward on a first conveyor 61 is transferred to a turntable 5 by a loading/ unloading mechanism L and the turntable 5 is rotated. An adhesive is applied to the bonding face (a) of the core plate 2 by a first adhesive application mechanism C1 and a plurality of friction material segments formed by cutting a friction material tape 41 and transferred from a cutting roller 44 are bonded to the bonding face (a) by pressing one by one by a first friction material segment bonding mechanism A1. After the plate 2 is reversed by a reversing mechanism R to turn the other bonding face (b) upward, an adhesive is applied, like the above, to this face (b) by a second adhesive application mechanism C2 and a plurality of segments are bonded to this face by a second friction material segment bonding mechanism A2 to obtain the title friction material disc 1 having a plurality of segments 3 on both the bonding faces (a) and (b) of the annular core plate 2 and oil grooves as deep as its thickness.
