Abstract
Resistance to tooth chipping in toothed belt in which rubber teeth are covered by a tooth cloth, is improved by providing for residual elongation of the tooth cloth so that it does not float or separate from the rubber teeth when tooth-deforming forces are applied, and by providing the tooth cloth with sufficient breaking strength so that the product of its breaking strength and its elongation are at least equal to a specified value.
