Method for manufacturing panels, and floor panel obtained hereby
A method for manufacturing panels includes at least the step of covering one or more side edges of a relevant panel, and moving the panel with its respective side edge relatively beyond an application device. The application device includes at least one nozzle, positioned in the plane of the panel when viewed at an angle of less than 90° to the corresponding side edge. A floor panel includes a covered side edge.
1 . A method for manufacturing panels, wherein the method includes at least the step of providing a covering or treatment including substance on one or more side edges of a relevant panel,
wherein the panel with its respective side edge is moved relatively beyond an application device,
wherein the application device comprises at least one nozzle,
wherein at least one nozzle viewed in the plane of the panel is positioned at an angle of less than 90° to the relevant side edge, and treats said relevant side edge with said substance;
wherein the substance is a water-repellant substance located upon at least a portion of a surface area of the relevant side edge and forming a discrete film or layer on the relevant side edge;
wherein the substance is applied by the at least one nozzle as an emulsion or dispersion, and then the panel undergoes a drying treatment with a drying device to form said film or layer.
2 . The method according to claim 1 , wherein first and second nozzles of said at least one nozzle are positioned at an angle of less than 90° to the relevant side edge and another relevant side edge, respectively.
3 . The method according to claim 2 , wherein the first and second nozzles are arranged in such a way that a first nozzle operates in a direction with a component which is opposite to the movement of the said panel and the second nozzle operates in a direction with a component which is parallel to the movement of the said panel.
4 . The method according to claim 3 , wherein at least one of the first and second nozzles is active both on the respective side edge and each time on one of the side edges adjacent to the respective side edge.
5 . The method according to claim 1 , wherein the covering or treatment includes another substance that is water-repellent.
6 . The method according to claim 1 , wherein the panel comprises a substrate with a decorative top layer applied to it.
7 . The method according to claim 6 , wherein the covering or treatment is applied at least near the edge of the decorative top layer on the relevant side edge.
8 . The method according to claim 1 , wherein the panel at least at the relevant side edge and an opposite side edge is provided with profiled edges comprising mechanical coupling parts, which enable two such panels to be coupled together at the corresponding side edges.
9 . The method according to claim 1 , wherein the panel in its upper surface adjacent to the side edge concerned is provided with a lower edge area.
10 . The method according to claim 1 , further comprising the step of sucking back an excess amount of substance through a suction line.
11 . The method according to claim 1 , wherein the substance penetrates the relevant side edge.
12 . The method according to claim 1 , wherein the at least one nozzle sprays or jets the substance onto the relevant side edge.
