Abstract
A method for manufacturing rectangular panels, wherein the panels have a substrate and a top layer. The panels are provided with a first pair of opposite edges, namely a first edge, and an opposite second edge. The method includes the steps of applying a liquid on at least a part of the first edge. The liquid penetrates the respective edge to a certain depth. The method further includes applying varnish on at least a part of the first edge while the liquid on the first edge is still wet.
Claims20
A method for manufacturing panels, wherein the panels are rectangular, either square or oblong, wherein the panels comprise a substrate and a top layer,
- wherein the panels are provided with a first pair of opposite edges, namely a first edge and an opposite second edge, wherein the method comprises steps of:
- applying a liquid on at least a part of the first edge, wherein the liquid penetrates to a certain depth in the first edge,
- applying lacquer on at least a part of the first edge while the liquid on the first edge is still in a wet state.
A panel, wherein the panel is rectangular, either square or oblong,
- wherein the panel comprises a substrate and a top layer,
- wherein the panel is provided with a first pair of opposite edges, namely a first edge and an opposite second edge,
- wherein the panel comprises coupling parts on the first pair of opposite edges, so that the panel can be coupled on the first edge of the second edge of another such panel,
- wherein a surface of at least one of the first edge and the second edge of the panel comprise a film,
- wherein the film has a thickness less than 50 micrometres.
A panel, wherein the panel is rectangular, either square or oblong,
- wherein the panel comprises a substrate and a top layer,
- wherein the panel is provided with a first pair of opposite edges, namely a first edge and an opposite second edge,
- wherein the panel comprises coupling parts on the first pair of opposite edges, so that the panel can be coupled on the first edge of the panel to the second edge of another such panel,
- wherein the coupling parts comprise locking elements so that in a coupled state, locking occurs in a direction perpendicular to a surface of coupled panels and/or locking occurs in a plane of the coupled panels and perpendicular to coupled edges;
- wherein the coupling parts on the first pair of opposite edges are configured as overlapping, so that during coupling on the first pair of opposite edges, coupling with pretension is obtained;
- wherein the panel is provided with a second pair of opposite edges, namely a third edge and an opposite fourth edge,
- wherein the panels comprise coupling parts on the second pair of opposite edges so that the panel can be coupled on the third edge of the panel to the fourth edge of another such panel,
- wherein the coupling parts comprise locking elements so that in the coupled state, locking occurs in the direction perpendicular to the surface of the coupled panels and/or locking occurs in the plane of the coupled panels and perpendicular to the coupled edges;
- wherein the coupling parts are configured as overlapping on the second pair of opposite edges, so that during coupling on the second pair of opposite edges, coupling with pretension is obtained;
- wherein each of the first edge, the second edge, the third edge and the fourth edge comprises a sealing face, substantially perpendicular to an upper surface of the panel,
- wherein in the coupled state of the panel with the first edge of the panel against the second edge of another such panel, the sealing face of the first edge of the panel is in contact with or is close to the sealing face of the second edge of the other such panel;
- wherein in the coupled state of the panel with the third edge of the panel against the fourth edge of another such panel, the sealing face of the third edge of the panel is in contact with or is close to the sealing face of the fourth edge of the other such panel;
- wherein the sealing faces of the third edge and of the fourth edge from each of the four corner points of the panel towards the middle of respectively the third edge and the fourth edge, at least over a certain distance from the respective corner point, are provided with an impregnating agent and/or a coating;
- wherein an average concentration of the impregnating agent and/or coating over a defined distance is higher than the average of the concentration of impregnating agent and/or coating on the sealing faces in the middle of the first edge and the second edge.
