Abstract
A method for manufacturing a laminate panel, where in a first step a press element is manufactured showing a surface relief. In a second step by means of the press element a relief is formed in a surface of the laminate panel, where the surface relief of the press element is provided with protrusions, which during pressing form recesses in the surface of the laminate panel. The recesses imitate wood pores. When manufacturing the press element, at least a number of the protrusions is made elongate and as such are formed substantially or essentially by a machining treatment with rotating cutting tools.
Claims20
A laminate floor covering comprising floor panels, wherein said floor panels consist at least of a substrate and a decor provided thereon, protected by means of a transparent synthetic material layer,
- wherein the synthetic material layers of the floor covering are provided with a relief comprising elongate recesses, wherein a said elongate recess has a cross-section which is provided with inclined lateral flanks,
- wherein these lateral flanks both have a flange portion with an inclination of more than 60° and less than 90°, and that the maximum depth over which said flank portions extend is larger than the maximum distance between the respective flank portions, measured in transverse direction and parallel to the plane of said floor covering;
- wherein said maximum depth is 0.1 millimeter or more;
- wherein the deepest point of said recess is located above the horizontal plane in which the decor extends locally;
- wherein said lateral flanks at the entrance of said recess and above the respective inclined flank portion are made with a rounding, wherein said rounding has a radius of less than 0.2 millimeters;
- wherein the length of said recess is at least 10 times the aforementioned maximum distance between the respective flank portions.
A method for manufacturing laminate floor panels for a laminate floor covering,
- wherein in a first step a press element is manufactured showing a surface relief, and
- wherein in a second step by means of said press element a relief is formed in surfaces of the floor panels, said floor panels consisting at least of a substrate and a decor provided thereon and protected by means of a transparent synthetic material layer,
- wherein said surface relief of the press element is provided with protrusions, which during pressing form chamfers in said surfaces of the floor panels, as such providing a floor covering comprising elongate recesses, wherein a said elongate recess has a cross-section which is provided with inclined lateral flanks,
- wherein these lateral flanks both have a flange portion with an inclination of more than 60° and less than 90°, and that the maximum depth over which said flank portions extend is larger than the maximum distance between the respective flank portions, measured in transverse direction and parallel to the plane of said floor covering;
- wherein said maximum depth is 0.1 millimeter or more;
- wherein the deepest point of said recess is located above the horizontal plane in which the decor extends locally;
- wherein said lateral flanks at the entrance of said recess and above the respective inclined flank portion are made with a rounding, wherein said rounding has a radius of less than 0.2 millimeters;
- wherein the length of said recess is at least 10 times the aforementioned maximum distance between the respective flank portions.
A heterogeneous vinyl floor covering comprising floor panels, wherein said floor panels consist at least of a substrate and a decor provided thereon, protected by means of a transparent synthetic material layer,
- wherein the synthetic material layers of the floor covering are provided with a relief comprising elongate recesses, wherein a said elongate recess has a cross-section which is provided with inclined lateral flanks,
- wherein these lateral flanks both have a flange portion with an inclination of more than 60° and less than 90°, and that the maximum depth over which said flank portions extend is larger than the maximum distance between the respective flank portions, measured in transverse direction and parallel to the plane of said floor covering;
- wherein said maximum depth is 0.1 millimeter or more;
- wherein the deepest point of said recess is located above the horizontal plane in which the decor extends locally;
- wherein said lateral flanks at the entrance of said recess and above the respective inclined flank portion are made with a rounding, wherein said rounding has a radius of less than 0.2 millimeters;
- wherein the length of said recess is at least 10 times the aforementioned maximum distance between the respective flank portions.
