Abstract: A belt having a rear face and a front surface, which is opposite the rear face, is suitable to be coupled to at least one pulley and has a plurality of nubs, which project from a band portion, in which cords are embedded; the nubs have the same shape and sizes as one another, are arranged along a plurality of rows parallel to a longitudinal axis of the belt, and are longitudinally spaced apart from one another with a constant pitch; each nub ends, in a longitudinal direction, with two end portions opposite one another and is provided with an intermediate portion, which joins the end portions to one another and has two sides, which are parallel to the longitudinal axis.
