Narrow surface coating device and method for applying a heat-activatable edge coating by means of hot air or hot gas

摘要

The invention relates to an edge coating device (1) for applying a ribbon-shaped edge strip (4) to narrow surfaces (6) of a workpiece (5), wherein the edge strip (4) can be fastened by heat activation to the narrow surfaces (6), in particular in multiple layers without adhesive or with a hot melt adhesive layer between edge strip (4) and narrow surface (6). The device comprises at least one feed device (7) for the edge strip (4) and a pressing device (9) that presses the heat-activated edge strip (4) against the narrow surface (6) of the workpiece (5). In the case of said edge coating device (1) and the corresponding coating method, an outlet (10) for hot air (16) is arranged in the region of the feed device (7) and/or pressing device (9). The opening applies the hot air (16) under a pressure of one bar or more onto the edge strip (4) and/or onto the heat-activatable layer of the edge strip (4) and/or onto the narrow surface (6) of the workpiece (5), wherein a heating device (3) is in fluidic connection for the hot air with the outlet (10). The heating device (3) brings the hot air (16) to the required activation temperature for the heat-activatable layer of the edge strip (4) or the hot melt adhesive.
