A method for dividing a board into a first panel and a second panel, the board being a laminated board, such as a floor element, comprising a core provided with a decorative surface layer and, preferably, a balancing layer, wherein the method comprises the step of forming a first vertically open groove through a rear side of the board and an offset second vertically open groove through the front side of the board, and wherein the method comprises the step of displacing the board in a feeding direction against a fixed tool and dividing the board by the fixed tool (22, 22b, 22c), wherein the fixed tool (22, 22b, 22c) is a carving tool, the fixed tool comprising several carving teeth, arranged for forming at different vertical and/or horizontal positions along the feeding direction, each carving tooth being fixed in an adjustable tool holder, and the fixed tool comprising several non-rotating and fixed chip-removing surfaces located after each other along the feeding direction, the method comprises the step of forming, by the fixed tool (22, 22b, 22c), a first horizontally extending groove that extends horizontally under the front side and/or the rear side of the board, said step of forming the first horizontally extending groove comprising removing chips, wherein the first horizontally extending groove extends from the second vertically open groove towards the first vertically open groove, or wherein the first horizontally extending groove extends from the first vertically open groove towards the second vertically open groove, and the method further comprises the step of removing the chips created by the forming, preferably by several compressed air nozzles. wherein the method comprises the step of forming a first vertically open groove through a rear side of the board and an offset second vertically open groove through the front side of the board, and wherein the method comprises the step of displacing the board in a feeding direction against a fixed tool and dividing the board by the fixed tool (22, 22b, 22c), wherein the fixed tool (22, 22b, 22c) is a carving tool, the fixed tool comprising several carving teeth, arranged for forming at different vertical and/or horizontal positions along the feeding direction, each carving tooth being fixed in an adjustable tool holder, and the fixed tool comprising several non-rotating and fixed chip-removing surfaces located after each other along the feeding direction, the fixed tool comprising several carving teeth, arranged for forming at different vertical and/or horizontal positions along the feeding direction, each carving tooth being fixed in an adjustable tool holder, and the fixed tool comprising several non-rotating and fixed chip-removing surfaces located after each other along the feeding direction, the method comprises the step of forming, by the fixed tool (22, 22b, 22c), a first horizontally extending groove that extends horizontally under the front side and/or the rear side of the board, said step of forming the first horizontally extending groove comprising removing chips, wherein the first horizontally extending groove extends from the second vertically open groove towards the first vertically open groove, or wherein the first horizontally extending groove extends from the first vertically open groove towards the second vertically open groove, and wherein the first horizontally extending groove extends from the second vertically open groove towards the first vertically open groove, or wherein the first horizontally extending groove extends from the first vertically open groove towards the second vertically open groove, and the method further comprises the step of removing the chips created by the forming, preferably by several compressed air nozzles.
