Abstract: The invention relates to a trimming device (21), in particular for a coating device (10) for coating narrow surfaces (12) of planar workpieces (11), having a cutting tool (22) by means of which a cutting movement (S) can be performed in order to trim a narrow-surface coating material (13), wherein the cutting tool (22) comprises a cutting region to which the narrow-surface coating material (13) can be transported in a direction of movement (B), wherein an adjusting device (23) is provided by means of which an adjusting movement (W) of the cutting tool (22) can be controlled in order to trim the narrow-surface coating material (13), wherein the adjusting movement (W) has at least one directional component directed in the direction of movement (B) of the narrow-surface coating material (13), as well as to a coating device (10) for coating narrow surfaces (12) of planar workpieces (11) with a narrow-surface coating material (13), and to a method for trimming a narrow-surface coating material (13) with a trimming

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.
