Disclosed is a gravure coating apparatus including: two frames; a first support shaft which is installed between the two frames; a rotary spline which is installed between the two frames and in parallel with the first support shaft; and multiple gravure roller modules which are installed to be fitted with the first support shaft and the rotary spline; in which the multiple gravure roller modules receive rotational force from the rotary spline and move independently along the first support shaft.

A tandem system of metering and donor rolls is used to apply two different adhesives to a fully adhesive backed multilayer sheet to produce variably distributed adhesives and properties. Each of the two adhesives is unique and is cured differently to create a layer of adhesive that has differing adhesive properties on the sheet. A clear adhesive is applied to a top portion of cards before they are cut from the sheet and has a higher tackiness than the adhesive applied to the rest of the cards on the sheet in order to reduce glue buildup on blades cutting the cards from the sheet.

A girth weld coating machine has an application head rotatable about a pipeline. A reservoir of coating material is carried on the application head and progressively dispenses coating material on to the girth weld. The coating material is applied to the pipe surface by a roller to spread and distribute the coating over the surface.

Any system described herein may be implemented in the context of an autonomous drywall installation robot. For example, an autonomous drywall installation robot may include one or more components such as a series of nested carriages, one or more drywall attachment mechanisms, one or more drywall positioning and fastening mechanisms, etc. In various other embodiments, any system described herein may be configured to utilize two or more robots described herein to work in conjunction toward one or more common goals. In one illustrative example, a first and second drywall installation robot may be configured to work in conjunction to: (1) lift a panel (e.g., a stone panel, tile, piece of drywall, sheetrock, gypsum board, or other construction board, etc.); (2) position the panel in a desired area; and (3) secure the panel in the desired area.

A system for applying a product (3) by roller is disclosed. The system has an applicator roller (1) for applying a product (3) on a substrate (4) and a first dosing roller (2) for dosing said product (3) on the surface of the applicator roller (1), wherein the system comprises at least one second dosing roller (2) configured to fine-tune the dosing performed by the first dosing roller (2), thereby adjusting the amount of product (3) dosed on the surface of the applicator roller (1).

An automated mobile paint robot, according to particular embodiments, comprises: (1) a wheeled base; (2) at least one paint sprayer; (3) at least one pump; (4) a vision system; (5) a GPS navigation system; and (5) a computer controller configured to: (A) generate a room painting plan using one or more inputs from the GPS navigation system, vision system, etc.; (B) control movement of the automated mobile paint robot across a support surface: (C) use the vision system to position the wheeled base in a suitable position from which to paint a desired area using the at least one paint sprayer; and (D) use the at least one pump to activate the at least one paint sprayer to paint a swath (e.g., swatch) of paint from the suitable position.
