Abstract: Method of manufacturing a padding cloth for belts said cloth having a latent curvability property, in which a belt-like cloth having a plurality of thermal shrinkage rates in the widthwise direction is subjected to heat-treatment under a relaxed condition so as to thermally stabilize the portion of the lowest thermal shrinkage rate, while retaining the residual latent shrinkages of the portions of higher thermal shrinkage rates. An adhesive powder is applied on the cloth and is secured firmly thereto by melting. If required, a supporting cloth having an adhesive applied on its upper face is further superposed on the belt-like cloth and is secured firmly to it with the adhesive of the supporting cloth.
