Varnish application process, apparatus for making this application process and use of such process

摘要

The present invention relates to a method for the application of lacquer to edges on plates and sheets, especially of the porous type, which are used within the furniture industry, where by changing the CAD reference dimension of the edge profile lacquer dosing unit it is possible to apply differentiated amounts of lacquer to predetermined areas. The invention also relates to a system for the application of lacquer to the edges on plates and sheets, especially of the porous type used in the furniture industry. Among other things, the system comprises one or more application rollers (9), possibly with a groove (10) in the surface of the individual roller (9) which can correspond to the edge profile (18) to which the lacquer is to be applied. The CAD reference can also be changed in the profile groove (10) of the application roller (9), or in both the roller (9) and the dosing unit (11). By using several units or application rollers (9) in succession, a particularly fine surface is obtained by allowing the application roller (9) which is placed last in the direction in which the work piece (18) is fed, to rotate in the opposite direction, whereby the excess lacquer is removed while at the same time a very well-defined thickness of lacquer is achieved. The method and the system are especially applicable in the lacquering of chipboards and similar porous plates, which are not homogeneous.
