ABSTRACT:
A precompact of flowable brake-lining composition is formed in an intermediate die by pressing the material in a direction perpendicular to the generatrices of the curved surfaces between which the material is pressed, whereupon the intermediate die is swung onto the hot-pressing die and the precompact transferred between synchronously driven rams into the hot-pressing die. A horizontal ram effects the final hot pressing of the precompact, advantageously directly bonding the same to a brakeshoe.
