Abstract
An apparatus and method of applying a finish or paint coating in a prefinishing or finishing line to a fencing panel or picket that disguises the screen-back texture of the engineered wood substrate. After paint or similar coating is applied (such as by one or more spray nozzles) to a face to a fence picket or fencing product or component, the fence picket passes under a roller, brush, or roller brush or similar paint applicator while the paint is still wet. The roller/brush removes some of the paint and applies an angled pattern to the face, which disguises the screen-back texture of the substrate.
Claims12
An apparatus for applying paint or coating to a wood or engineered-wood panel or component on a prefinishing or finishing line, comprising:
- one or more first applicators configured to apply a coating or paint to a top face of a wood or an engineered-wood panel or component conveyed on the prefinishing or finishing line with a direction of travel and a lateral axis orthogonal to the direction of travel;
- and
- a second applicator with a longitudinal axis, said second applicator extending across the prefinishing or finishing line at an acute first angle with respect to said lateral axis, and configured to apply an angled pattern with linear elements at an approximate second angle with respect to the direction of travel in the applied coating or paint as the wood or engineered-wood panel or component moves past the second applicator on the prefinishing or finishing line;
- wherein the second applicator comprises a roller, brush or roller brush that comes into contact with the applied coating or paint on the face of the wood or engineered-wood panel or component;
- and
- wherein additional paint or coating is applied by the second applicator.
