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 panel wherein this panel consists at least of a substrate on the basis of polyvinyl chloride (PVC), polypropylene (PP) or polyurethane (PU) and a printed decor provided thereon, protected by a transparent synthetic material layer on the basis of PVC, PP or PU, wherein the transparent synthetic material layer is provided with a relief comprising elongate recesses, wherein said elongate recesses over the major part of their length have 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 surface plane of said panel.
A method for manufacturing laminate panels, wherein said laminate panels consists at least of a substrate on the basis of PVC, PP or PU and a printed decor provided thereon, protected by a transparent synthetic material layer on the basis of PVC, PP or PU, wherein the transparent synthetic material layer is provided with a relief comprising elongate recesses, wherein said elongate recesses over the major part of their length have 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 surface plane of said panel,
- wherein in a first step a press element is manufactured showing a surface relief, and wherein in a second step by means of this press element a relief is formed in a surface of the laminate panel, wherein said surface relief of the press element is provided with protrusions, which during pressing form recesses in said surface of the laminate panel, said recesses imitating wood pores, wherein when manufacturing the press element, at least a number of said protrusions is made elongate and as such are formed substantially or essentially by a machining treatment with rotating cutting tools.
A laminate panel wherein this panel consists at least of a substrate on the basis of PVC and a printed decor provided thereon, protected by a transparent synthetic material layer on the basis of PVC, wherein the transparent synthetic material layer is provided with a relief comprising elongate recesses, wherein said elongate recesses over the major part of their length have 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 surface plane of said panel, wherein the substrate comprises fillers and wherein the minimum distance between the respective flank portions, measured in transverse direction and parallel to the plane of said panel, is smaller than half of said maximum distance between these flank portions.
