Abstract
A flexible belt, made of an elastomeric material, comprising an annular body, delimited by two base surfaces and by two lateral sides; at least one of the base surfaces disposed with a predetermined winding arc around a pulley from which it receives or, to which it transmits, motion by friction. The sides of the annular body are inactive for transmitting the forces by friction. The belt that is for example, flat, is extensible, and it comprises at least one group of three layers in direct contact with one another, each layer of which includes or comprises reinforcing fibers disposed in a single predetermined direction. In the reinforcing structure no inextensible cords are present. The belt may comprise an annular element on at least one of the base surfaces of the annular body, for opposing any lateral shifting relative to the transmission pulley.
