Abstract
A method of producing a reinforced plastics toothed belt having a fabric cover on the toothed side of the belt. Formed between a molding wheel and a molding wheel cover is a mold cavity into which the liquid plastics material, the reinforcing wires, and the strip of fabric are introduced. The strip of fabric, which is resiliently extensible in its longitudinal direction, is wetted, in the unextended state, before being introduced into the mold cavity, with an adhesive agent which hardens by drying and softens again under the temperature of the liquid plastics material. After the drying of the adhesive agent, the strip of fabric is introduced into the mold cavity and is placed on the teeth of the molding wheel. In the mold cavity, the strip of fabric is heated on meeting the liquid plastics material, is made resiliently extensible again as the adhesive agent softens, and is pressed into the grooves between the teeth of the molding wheel by the plastics material.
