    Abstract: The present invention provides an improved multi-mold apparatus for manufacturing friction members, with each mold composed of a set comprising a first (top) mold, a second (bottom) mold, and a frame mold. The apparatus is capable of correcting any misalignment in the mountings of the plurality of molds and accurately aligning the molds by movably supporting at least one of the first mold, the second mold and the third mold by first, second and frame bases, respectively, so that the base and molds are movable laterally, in a direction perpendicular to the direction of advance. Projections are formed on one of the first mold and either the frame mold or the back plate and bonding through-holes are formed on the remaining mold or the back plate, so that the projections engage the holes so as to align the first mold and the frame mold accurately.
