ABSTRACT:
Apparatus for performing a friction material includes a friction material-charging device for charging an appropriate amount of a friction material into a cavity in an intermediate die member receiving a lower die member therein; a leveling device including a base having a plurality of narrow bars depending from the base, a first elevator mechanism for vertically moving the base, so that when the base is moved downward, the narrow bars are inserted into the cavity, and a device for imparting a horizontal reciprocal movement to the base when the base is moved downward, so as to level the friction material by the narrow bars; a recess-pressing device including a push rod, and a second elevator mechanism for vertically moving the push rod, so that when the push rod is moved downward, the push rod is inserted into the cavity in the intermediate die member so as to press the friction material into the recess; and a pressing device including a third elevator mechanism for vertically moving an upper die member, so that when the upper die member is moved downward, the upper die member is fitted in the cavity in the intermediate die member so as to press the friction material.
