Abstract
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.
