Abstract:
1. Method for manufacturing floor elements, which comprise at least a substrate, a decorative element defining at least partially an upper side of a respective floor element, and the floor elements having coupling parts at least at two opposite sides, wherein the floor elements, at least at one of these sides, are provided with an edge portion formed of a synthetic material, and the substrate of each of the floor elements is mainly constructed of a material other than the material of the synthetic material edge portion, wherein the method comprises at least the following steps: producing a semi-finished product comprising at least said substrate, said edge portion and said decorative element; and then performing a machining treatment on said edge portion of the semi-finished product in order to fabricate at least a portion of the coupling part to be formed therein; wherein the coupling parts at said two opposite sides are formed as substantially a male coupling part and a female coupling part, both of which including vertically active locking portions, which, when the coupling parts of two of such floor elements are coupled and cooperate with each other, effect a locking in a vertical direction, perpendicular to a plane of the floor elements, and also include horizontally active locking portions, which, when the coupling parts of two of such floor elements are coupled and cooperate with each other, effect a locking in a horizontal direction, perpendicular to respective sides of the floor elements and in a plane of the coupled floor elements, wherein said coupling parts are configured so as to enable two of the floor elements to be connected to each other at said sides by pushing one of the floor elements with the associated male coupling part, by means of a downward movement, home into the female coupling part of the other floor element; wherein the downward movement used to couple the floor elements, as seen in a cross-sectional view, is generally in a linear direction having a substantially greater vertical component than a horizontal component; wherein said synthetic material edge portion is formed to define an elastically deformable first portion arranged as one of the vertically active locking portions, and a second portion by which the edge portion is adheared to the substrate; wherein said female coupling part defines a projecting end part formed by the substrate and bordering the female coupling part towards a bottom of the female coupling part along a lower side of the respective floor element; wherein said projecting end part defines one of the horizontally active locking portions, said one of the horizontally active locking portions being formed by the substrate; and wherein said horizontally active locking portion is formed to have a horizontally active locking surface, said horizontally active locking surface being under an angle with respect to a horizontal direction of the floor element and arranged for abutment with a locking part defined by said male coupling part of the coupling floor element; wherein, when producing said semi-finished product, said synthetic material edge portion is provided as an insert.
