  • Patent number: 6596119
    Abstract: This invention relates to a manufacturing method and a manufacturing apparatus of friction plate for clutch. The present invention intends to provide the manufacturing method and the manufacturing apparatus of friction plate for clutch which can adhere the plural friction material segments to the core plate in shorter time period than that in the conventional art. The manufacturing method comprises a step for containing plural friction material segments 2 on a one surface 70a of a holding body 4 circumferentially; and a step for making the one surface of said holding body 4 and an adhering surface of a core plate 8 coated with an adhesive agent come near to each other, and for adhering the friction material segments 2 held by said holding body 4 to the adhering surface of said core plate 8 by urging.

  • Patent number: 6499579
    Abstract: A wet type friction member includes a core plate, a plurality of segmental friction units and oil grooves. The segmental friction units are bonded on the core plate at intervals in a ring-shaped manner. The oil grooves are demarcated and formed by facing end surfaces of neighboring two pieces of the segmental friction units, and connect an inner peripheral side of the core plate with an outer peripheral side thereof. At least one of the facing end surfaces of the segmental friction units have a cut-off portion, which is cut off inwardly, at an inner peripheral side end of the facing end surfaces and/or an intermediate portion thereof. The oil grooves are provided with a major-width portion of a wide groove width by the cut-off portion at an inner peripheral side opening of the oil grooves and/or an intermediate portion thereof.
