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.
Claims11
A method for reinforcing a shoe upper, comprising:
- applying a reinforcing material onto a receiving surface through a shaped cut-out;
- heating said reinforcing material on said receiving surface;
- transferring said heated reinforcing material from said receiving surface to a shoe upper by applying a shoe upper thereagainst;
- and
- cooling said upper during the application of pressure between said upper and said reinforcing material on said receiving surface.
A method for reinforcing a shoe upper, comprising:
- applying a powdered reinforcing material onto a permeable receiving surface through a shaped cut-out so as to define a three-dimensional configuration of powder on said permeable receiving surface;
- heating said powdered reinforcing material on said permeable surface so as to fuse said powder into a molten three-dimensional said fused configuration, for a bubble free product;
- cooling said heated molten configuration by chilling means during pressure of a shoe upper thereon, to effectuate release of said configuration from said permeable receiving surface;
- and
- pressing a shoe upper onto said configuration of reinforcing material for securement thereto.
A method of utilizing a fusible powder which is adaptable to change the stiffness or decorative characteristics of a substrate, comprising:
- arranging a partial peripheral partition of diminishing thickness towards the ends thereof onto the bottom side periphery of a cut-out on a stencil means;
- depositing a fusible powder in a holding means having said stencil means therewith;
- sweeping said fusible powder by a blade means through said cut-out in said stencil means;
- receiving said fusible powder on a receiving surface arranged beneath said stencil means;
- accumulating said fusible powder in a three-dimensional configuration on said receiving surface within the confines of said partial peripheral partition disposed on the bottom of said cut-out which raises only that partially partitioned portion of the cut-out of said stencil from said receiving surface for subsequent application of said powder after further treatment thereof, to a substrate to effectuate changes of its stiffness or decorative characteristics;
- transferring said receiving surface to a heating means to fuse powder configuration thereon and then transferring said receiving surface to a cooling means to cool said fused configuration prior to the application of said powder to a substrate;
- pressing a substrate onto said fused configuration of powder on said receiving surface, so as to join them together, thereby changing the characteristics of said substrate therewith.
