Claims8
A toothed belt comprising an elastomeric or plastic continuous band, a reinforcing structure embedded in said band, a toothing on at least one face of the band and a covering for the toothing, characterized in that said covering is constituted by at least two layers of fabric doubled together with a layer of elastomeric or plastic material interposed therebetween, whereby said covering is an extremely rigid layer which is substantially non-deformable by flexion stresses in comparison with the elastomeric or plastic material forming the toothing.
