METHOD AND APPARATUS FOR THE APPLICATION OF PLASTICS COATINGS

摘要

The invention relates to an apparatus for the application of coatings to surfaces of substrates in the form of paper, paperboard, or plastics foils, preferably for the finishing of print products. The apparatus encompasses a coating unit for the application of coating material in fluid form to the substrate surface, and equipment for smoothing of the film while it is still fluid after it has been applied by means of the coating unit to the substrate surface, where the equipment encompasses equipment for generating a gas stream orientated onto the substrate surface coated with the film, where the gas stream smooths the film with at least partial elimination of undesired structures in the film surface, e.g. depressions, elevations and craters, prior to the hardening of the coating material.
