A mask sheet fixed to a mask frame includes a first zone in which a plurality of holes are arranged, a second zone outside the first zone and including an edge of the mask sheet, a third zone between the first zone and the second zone and fixed to the mask frame, and a plurality of grooves arranged in the second zone.

A portable coating device for applying a coating solution onto a solar panel includes a supply module for supplying the coating solution, a base, a spraying module disposed on the base, a transmission module disposed at two opposite ends of the base, an arc bracket, and an applicator. The base spans the solar panel and moves thereon through the support of the transmission module. The arc bracket is disposed at the bottom of the base and has a plurality of seepage openings, and an inner surface of the arc bracket faces the spraying module. The applicator includes a porous material that deforms under pressure. The applicator is assembled to the base and supported by the arc bracket.

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.
