Abstract
A method of applying a configuration of reinforcing/stiffening material in powder form to a receiving surface, for subsequent fusing, cooling and pressing to a shoe upper. The method comprises the utilization of a deposition station, a heating station and a press station. A tension receiving belt receives the configuration of powder through a cut-out in the bottom of a swept container. The receiving belt is supported from beneath during the deposition activity. The receiving belt is shuttled in timed steps to the successive stations for melting the powder and subsequent adhesion of the melted powder to an unreinforced shoe upper in a displaceable frame.
