An apparatus has first and second coating nozzles for applying a liquid coating material respectively to two sides of a running flat material web, and has first and second rigid supply line sections for supplying the coating material to the respective coating nozzles. At least one of the coating nozzles is transferable from a working position to a maintenance position and back. In the working position, throughflow channels in the supply line sections communicate with one another to provide a throughflow of the coating material to the coating nozzles. When transferring at least one of the coating nozzles from the working position to the maintenance position, the rigid supply line sections are automatically moved relative to one another so that the throughflow channels therein are interrupted so as to interrupt the flow of the coating material to this coating nozzle.

Devices and methods for preparing a slurry for coating onto a substrate. The devices and methods of the present disclosure relate to providing a slurry in a closed volume with at least one passage. The slurry includes a solvent, a powder, and a binder. The slurry can also include a dispersion agent. The slurry is forced repeatedly under high pressure through the at least one passage in a first flow direction and then back through the at least one passage in a second flow direction, opposite the first flow direction. The forcing homogenously disperses the powder and the binder within the solvent. Both sides of the substrate are then coated simultaneously with the slurry extruded from the closed volume after the forcing. Curing of the coated slurry includes freeze drying to preserve the porosity of the slurry on the substrate.

To provide a palette, etc. on which an article is placed, including: a foamed synthetic resin-base material; and a polyurea-resin coating layer covering a front surface of the base material; and manufactured by a method including: injecting a polyurea-resin coating material onto a front surface of a foamed synthetic resin-base material; and drying the coating material after the injecting. The injecting may have injecting the coating material onto all surfaces of the base material. A thickness of the coating material formed on a front surface of the base material in the injecting may be controlled proportionally to an expansion ratio of the foamed synthetic resin. The thickness of the coating material may be controlled by adjusting a speed of conveyance of the base material and/or a distance between an injection port for the coating material and the base material. Heating-pressing the base material may further be included before the injecting.

A coating apparatus can be used to concurrently coat both sides of a substrate while assuring a VOC free atmosphere outside the equipment. The coating apparatus can be used in-line, where flat materials and substrates that are typically carried along a conveyer may enter the coating apparatus, usually without requiring the substrate to be moved into any other configuration. The coating apparatus may be configured to permit the user to perform any number of treatment steps while providing isolation between the steps. The substrate can be partially suspended by the coating apparatus to permit both sides to be treated at the same time. A vacuum system, including redundant perimeter negative pressure venting ducts, can create a vacuum perimeter wall around the moving, treated material to ensure a VOC free atmosphere outside the coating apparatus.
