The deformations and stresses in an initially straight belt, bent and sheared around a rigid cylindrical drum, are theoretically investigated. The belt is made of a Mooney-type material and reinforced by a cord layer, assumed thin and inextensible. Three types of solutions are obtained, where the actual type is shown to depend on the conditions of the initial application of the belt to the drum.
