Abstract: A device according for coating workpieces of wood, wood materials, plastic, aluminium or the like, includes: a feed device for feeding a coating material; a pressing device for pressing the coating material onto a surface of a workpiece; a conveying device for inducing a relative movement between the pressing device and the respective workpiece; and an activation device for activating an adhesive on a coating material fed by the feed device and/or for activating an adhesive on a surface of a workpiece to be coated. The activation device includes at least one supply line for supplying an activation medium as well as a nozzle body having an activation medium inlet duct and an activation medium outlet region. The activation medium outlet region includes at least one outlet opening. The activation device also includes precisely one closure to close the outlet opening of the activation medium outlet region.

Abstract: A device for coating workpieces preferably consisting at least in parts of wood, wood materials, plastic, aluminium or the like, comprises: a feed device for feeding a coating material; a pressing device for pressing the coating material onto a surface of a workpiece; a conveying device for inducing a relative movement between the pressing device and the respective workpiece; and an activation device for activating an adhesive on a coating material fed in the feed device and/or for activating an adhesive on a surface of a workpiece to be coated. The activation device comprises at least one supply line for supplying an activation medium as well as a nozzle body having an inlet duct and an outlet region. The activation device comprises at least one acoustic element that is configured to reduce the sound pressure resulting from the flow of the activation medium and/or to effect a frequency shift.

Abstract: The present invention discloses a supply system for supplying a coating material to a feed device for feeding a coating material to a machining device, wherein the supply system comprises: a storage device configured to store at least one coating material, and a manipulator configured to transfer coating material between the feed device and the storage device.

Abstract: A hot gas generation device with which a gas flow, for example, an air flow, is heated. This device is used for heating an edge band or another coating material, in particular an adhesive layer provided on this coating material. In this way, the coating material is prepared for being applied to a (wooden) work piece, which may, for example, be plate-shaped.

Abstract: A method for applying powder to a printed sheet includes ejecting air flows from a nozzle bar. The air flows are set in such a way that the air flows which are ejected per meter length of the nozzle bar produce a resultant force acting on the printed sheet of from 0.5 newtons to 16 newtons. A printing press for carrying out the method is also provided.
