Abstract: A molding apparatus of a wet friction material has a pair of guide posts vertically extending on a molding apparatus main body. The pair of the guide posts passes through fifteen stages (sixteen pieces) of molding dies. A pair of pantograph-type open-close mechanisms is attached to opposite side surfaces of the molding dies. Thus, the molding dies are piled up on each other so as to come near to each other (mold clamping) and move apart from each other (mold opening).

If the molding dies are slid at a speed of 200 mm/sec, it takes only 3.75 seconds (50 mm*15/200 mm=3.75 sec). It takes a double of that time or 7.5 seconds, that is a half of the time of a related art.
