The manufacturing of footwear includes the joining of components. The joining may be accomplished with adhesive. The adhesive, such as a polyurethane, is applied as a single-sided adhesive to a footwear component. The application of the adhesive can contaminate the system that is applying the adhesive with intentional over spray of the footwear component. The over spray ensures adequate coverage of the footwear component to allow a sufficient bond. A masking platform of the system masks portions of the system to limit the contamination caused by the over spray. Additionally, material brushes and scrapers may engage with components of the system to remove or limit adhesive contamination on those components. A vision system maps a surface of the footwear component to ensure the adhesive is applied for the specific article.

An improved assembly method in making a shoe, and an applied correction solution. In the method, according to the porosity or the density of a material to be bonded, correction solutions of different concentrations are added to a TPU binder of a single viscosity, so as achieve the viscosity of the TPU binder, and to overcome the problem of storage and management of various types of binders, and the assembly steps can be simplified.

Systems apply a material (e.g., adhesive) to an article (e.g., a component in an article of footwear) with a multiple-nozzle tool. A first nozzle of the multiple-nozzle tool is effective to provide an edge application of the material that is consistent in application of the material. A second nozzle of the multiple-nozzle tool is effective to provide a greater material coverage application than the first nozzle. The second nozzle may be implemented to apply the material at an interior area from the edge at which the first nozzle applies the material, in an exemplary aspect.

A smart oven includes a box body unit, a heating unit and a feed unit. The box body unit includes a box body that has a first inner wall surface, two second inner wall surfaces, two third inner wall surfaces, and a heating chamber having a chamber opening that faces downward. The heating unit includes a plurality of upper radiation heating lamps disposed above the chamber opening, and a plurality of outer radiation heating lamps disposed in proximity to the second and third inner wall surfaces. The feed unit includes a carrier platform that is movable relative to the box body between a material-placing position and a material-operating position, in which the carrier platform is distal from and closes the chamber opening, respectively.
