Abstract
A feed device which can feed a friction material mixture into a mold so that its thickness will be uniform in the mold to improve the quality and stability of the friction member obtained by heating and pressure-molding the material mixture in the mold. The feed device has a feeder for feeding a friction material mixture supplied from a constant-feed device at a constant rate to a designated area. The feeder comprises a main conveyor and sub-conveyors provided right under the delivery end of the main conveyor and inclined with respect to the main conveyor. The material mixture is partially dropped from the delivery end of the main conveyor onto the sub-conveyors, and fed to the delivery ends of the sub-conveyors and dropped into a mold having a hood. The shape of the delivery end of the feeder can be adjusted substantially to the arcuate shape of the mold cavity. By further moving the feeder and the mold relative to each other in the X-axis direction, the thickness of the material fed into the mold will be even more uniform.
