In the production of a brake shoe which comprises a carrier plate 22, an intermediate layer 24 and a friction lining 23, a heat-hardenable composition is mixed with a heat-actuatable adhesive, and the mixture is applied to a fibrous web 7 and is uniformly spread and then dried. An intermediate layer of appropriate size is then obtained from the composition and is subsequently joined to the carrier plate and a powdered friction layer material by pressing and heating to form the finished brake shoe. The intermediate layer may, prior to the application of the friction layer material and of heat and pressure, be bonded to the carrier plate using a solvent which partially activates the adhesive, so that the carrier plate and attached intermediate layer form a unit which can be stored prior to application thereto of the friction layer material. <IMAGE> |
