<p>A push-type metal V-belt for use with V-grooved pulleys is produced from a single formed and fan-folded strip of sheet metal. The folded strip (10) has alternately tight-folded and open-folded portions (16 and 12) of differing heights when viewed edgewise of the open-folded portions. During the forming of the strip, adjacent drive edges are formed such that, when folded, these edges are aligned so as to become drive surfaces of the belt, the drive surfaces comprising the outer edges of a substantially trapezoidal surface. During the forming of the strip, also, a plurality of lateral slots (34, 36) are formed to provide a space for housing a plurality of metal bands (46) which maintain the fan-folded strip in a continuous-loop configuration.</p> |
