Segment-type wet friction material, its manufacturing apparatus and its manufacturing method

Abstract

In manufacturing a segment-type wet friction material, each segment piece in a guide is pushed out and mounted on a rotating plate. Cut portions at opposite outer peripheral corners of the segment piece are fitted and engaged with two positioning pins so as to position the segment piece on the rotating plate. The segment piece is sucked by a pair of positioning suction holes located thereunder so as to be fastened. The rotating plate is turned 18 degrees and such operation is repeated until twenty segment piece are charged in a ring shape. Then, each two suction heads of a sucking/moving mechanism sucks surfaces of each segment piece. At the same time, a sucking operation of the positioning suction holes is stopped. Then, the twenty segment pieces arranged in the ring shape is lifted by the sucking/moving mechanism and moved in parallel to a core metal with an adhesive coated on an entire surface thereof. The twenty segment pieces are pressed to the core metal so as to adhere thereto.
