Embodiment Construction

[0036] As previously stated, the present invention relates to a method for coating a product on a substrate (112) and a system using said method.

[0037] Figure 1a , 1b and 1c show the sequence of applying varnish for a coating system corresponding to a varnishing machine comprising two successive heads, wherein in the first coating head (111) the first coating roller ( 122 ) rotates in the same direction as the advancement of the substrate ( 112 ), while the second coating head ( 122 ′) rotates in the opposite direction, ie in the opposite direction to the movement of the substrate ( 112 ). In this sequence, the ridges produced on the leading (118) and trailing (119) edges of the substrate can be seen, produced in varnishing machines of the state of the art. In this type of machine, the substrate (112) is transported thanks to conveyor belts or transport rollers (124).

[0038] In connection with this type of coating head (111, 111'), dispensing rollers (121, 121') are ar...

Abstract

The present invention seeks to solve one or more of the drawbacks explained previously by means of a method for applying a product by roller on a surface of a substrate (112) transported horizontally with respect to an application head (111, 111'), which comprises moving the application head (111, 111') immediately from a lowered position of the application head (111, 111'), wherein the application roller (122, 122') applies product in a predetermined position of the surface of the substrate, to a raised position of the application head (111, 111'), wherein the application roller (122, 122') does not apply product; or vice versa. The invention also relates to the application system using said method.

Description

technical field [0001] The invention relates to a method for coating a fluid product or material, such as varnish or glue, on a substrate by a roller, and to a coating system. Background technique [0002] The flat varnishing or gluing of mass-produced furniture and similar components is carried out in varnishing and gluing lines. These lines consist of several machines, each capable of performing an operation of a previously selected process. [0003] The process of varnishing flat surfaces, such as panels and / or boards of furniture, is generally carried out with varnishing machines and drying tunnels. In the same way, the gluing of the planes is carried out with a gluing machine. [0004] The application of varnish or glue is established by means of rollers arranged on the head, which can also be carried out respectively by means of at least two combined rotating rollers. [0005] The first roll, called the "coating roll", is responsible for coating the product on the s...
