Abstract
A push-type metal V-belt for use with V-grooved pulleys is produced with a single formed and fan-folded strip of sheet metal. The folded strip has alternately tight-folded and open-folded portions having less height when viewed edgewise of the open-folded portions. During the forming of the strip, adjacent drive edges are formed so that when folded, these edges are aligned so as to become drive surfaces of the belt. When viewed in a lateral section, the drive surfaces are the outer edges of a substantially trapezoidal surface. Also, during the forming of the strip, a plurality of lateral slots are formed to provide an area or space for housing a plurality of metal bands which maintain the fan-folded strip in a continuous belt or loop configuration.
