Problems solved by technology

It may specifically occur that the liquid curtain of the coating stock breaks at the ends when the ends of the plates guided past the curtain bend downwards
Moreover, when the front part of the board guided past the curtain is bent downwards, there is a risk that the front part of the board is bumped during contact with the output conveyor
Thus the coating process is interrupted

Embodiment Construction

[0031] refer to Figure 2-Figure 12 Those skilled in the art will recognize that these figures only show essential components and are not true to scale. For example, the transport device is substantially longer than the part to be coated, and the part to be coated is significantly thinner relative to its length. In existing prototypes, each of the two conveyors is e.g. longer than 4 meters, and the part to be coated is a wooden board from which a floor is made, in particular a layer with a thickness of only 6-10 mm and a length of more than 2 meters shape board. The gap between the two conveyors of the prototype is about 50 cm.

[0032] Below, based on figure 2 The general structure of the device according to the invention is explained. Figure 3-Figure 12 The diagrams are mostly the same, so in the following explanations of these figures, only a few differences are mentioned.

Abstract

The invention relates to an installation (10) and a method for curtain-coating panel-shaped components (60), as well as components that have been produced using such a method. The installation comprises a device (40) for producing a liquid curtain (42) of coating material, an inlet conveyor device (20) and an outlet conveyor device (30). Said outlet conveyor device (30) and / or the inlet conveyor device (20) can be height-adjusted.

Description

technical field [0001] The present invention relates to a device and a method for curtain-coating of plate-shaped parts, such as MDF panels (MDF: Medium Density Fibreboard) or HDF panels (HDF: High Density Fibreboard). Background technique [0002] Several devices and methods for coating the surface of plate-shaped parts are known from the prior art. A coating device is known, for example, from WO 2009 / 074174 A1 of the same applicant, in which the raw material is transferred to the application belt by means of application drums. Afterwards, the application belt is pressed onto the plate-shaped part to be coated by means of a pressure drum, whereby the liquid coating material is transferred from the coating belt to the surface of the part to be coated. Thus, the conveyor belt together with the coating belt guides the plate-shaped part through the device. A disadvantage of this drum-based application method is that the transferred coating includes a corrugated surface due to...
