Abstract
Floorboards are shown, which consist of a core and a surface layer and are provided with decorative joint edges which are formed by removing the surface layer.
Claims37
A system for making a decorative joint portion at two adjoining joint edges of laminate floorboards that are adapted to be joined together at a vertical joint plane, wherein each of the floorboards comprises:
- a wood-fiber based core and a laminate surface layer arranged on substantially an entire portion of an upper side of the core and connectors arranged at said adjoining joint edges for joining the floorboards with each other in the vertical or horizontal direction,
- the laminate surface layer forming a horizontal plane,
- wherein at one of said adjoining joint edges, the laminate surface layer does not extend to the vertical joint plane so that a portion of the core adjacent the vertical joint plane is exposed and the exposed portion of the core is essentially parallel to the horizontal plane.
A laminate floorboard, comprises:
- a wood-fiber based core;
- a laminate surface layer arranged on an upper side of the core;
- and
- connectors arranged at opposite joint edges of the floorboard for joining the floorboard with an essentially identical floorboard in the vertical or horizontal direction,
- the surface layer forming a horizontal plane,
- wherein at least one of the joint edges of the floorboards an impregnated part of the core is exposed, and
- a substantially vertical surface extends between the exposed impregnated part of the core and the connector at the at least one joint edge.
A system for making a decorative joint portion at two adjoining joint edges of laminate floorboards, wherein each of the floorboards comprises:
- a wood-fiber based core and a laminate surface layer forming a horizontal plane and arranged on an upper side of the core and connectors arranged at said adjoining joint edges for joining the floorboards with each other in a vertical or horizontal direction, and
- a groove is formed in the laminate surface layer adjacent to at least one of said adjoining joint edges, the groove has a bottom surface and at least one lateral surface, the lateral surface extending to the horizontal plane and having a first angle to the horizontal plane, the bottom surface having a second angle to the horizontal plane, said first angle being greater than said second angle, and the bottom surface being formed in the core.
A floorboard system comprising a plurality of floorboards, each of the floorboards comprising:
- a core made of wood-fiber based material and a surface layer which is arranged on an upper side of the core, the surface layer having a substantially planar outer surface facing away from the core and extending in a horizontal plane,
- each of the floorboards comprising connectors at opposing edges thereof for connecting the floorboard to an adjacent one of the floorboards in a vertical direction and along a vertical joint plane,
- wherein at a portion of each of the floorboards adjacent at least one of the connectors, a portion of the core is not covered by the surface layer so that the portion of the core is exposed when the at least one connector is connected to a connector of an adjacent floorboard, and the exposed portion extends horizontally in a plane that is essentially parallel to the horizontal plane.
A laminate floorboard comprising a core made of wood-fiber based material and a laminate surface layer arranged on an upper side of the core and connectors arranged at opposite joint edges of the floorboard for joining the floorboard with an essentially identical floorboard in the vertical or horizontal direction, the laminate surface layer forming a horizontal plane, and the laminate surface layer comprising an upper layer and an underlying layer,
- wherein at a portion of the floorboard adjacent at least one of the opposite joint edges, the underlying layer is exposed and the exposed portion extends horizontally in a plane that is essentially parallel to the horizontal plane, and
- wherein the exposed underlying layer is visible from the upper side of the floorboard when the floorboard and an adjacent floorboard are connected.
