ABSTRACT:
A method of carrying preforms of frictional material, in which a preform 2 of a frictional material is carried so as to be put into a heat middle mold 8b of a heat mold 8 after the frictional material is preformed with a preforming mold 1, the preforming upper mold 1a is moved down so that the preform 2 held in a preforming middle mold 1b is pushed from above into a through storage hole 4a of a carrier 4, and the heat upper mold 8a is moved down after this carrier 4 is carried to above the heat middle mold 8b so that the preform 2 is pushed into the heat middle mold 8b from the lower portion of the storage hole 4a of the carrier 4.
