20140076493 | FOOTWEAR PARTS GLUING PROCESS USING POWDER ADHESIVE - A process of gluing footwear parts using a powder adhesive that eliminates the conventional stages of drying required after the application of liquid adhesive to the substrate surface and of cooling to solidify the glue after pressing is disclosed herein. The process comprises the stages of preparing the surface and removing impurities from substrates by applying a slow-drying compound featuring bonding properties; applying the polyurethane-base powder adhesive with a grain size between 30 and 200 microns by dispersing it with pistols removing the excess adhesive; reactivating the powder adhesive applied to the substrate surface at temperatures between 60° and 80° C.; joining the substrate surfaces that received the adhesive, and pressing. | 03-20-2014 |
