Abstract
Floorboards provided with a mechanical locking system including a locking strip protruding from a first edge of a first floorboard. The locking strip is provided with a locking element configured to cooperate with a locking groove at a lower side of a second edge of a second floorboard for locking the first edge and the second edge in a horizontal direction. The first edge and the second edge are configured to be assembled by a vertical downward motion of the second edge towards the first edge. The second edge is provided with a calibrating groove adjacent the locking groove. Also, a method for producing a mechanical locking system.

Floorboards including a mechanical locking system, the mechanical locking system comprising a locking strip protruding from a first edge of a first floorboard,
- wherein the locking strip includes a locking element configured to cooperate with a locking groove at a lower side of a second edge of a second floorboard for locking the first edge and the second edge in a horizontal direction,
- wherein the first edge or the second edge includes a tongue configured to cooperate with a tongue groove at the other of the first edge or the second edge for locking of the first edge and the second edge in a vertical direction,
- wherein the first edge and the second edge are configured to be assembled by a vertical downward motion of the second edge towards the first edge,
- wherein a core of the first floorboard comprises a plastic material and a core of the second floorboard comprises a plastic,
- wherein at least said second edge is flexible, wherein said second edge includes a calibrating groove adjacent said locking groove,
- wherein the calibrating groove is open towards the locking groove, and
- wherein the calibrating groove is configured such that the second edge is bendable downwards until a locking position in which the tongue enters into the tongue groove is reached.
Floorboards including a mechanical locking system, the mechanical locking system comprising a locking strip protruding from a first edge of a first floorboard,
- wherein the locking strip includes a locking element configured to cooperate with a locking groove at a lower side of a second edge of a second floorboard for locking the first edge and the second edge in a horizontal direction,
- wherein the first edge or the second edge includes a tongue configured to cooperate with a tongue groove at the other of the first edge or the second edge for locking of the first edge and the second edge in a vertical direction,
- wherein the first edge and the second edge are configured to be assembled by a vertical downward motion of the second edge towards the first edge,
- wherein a core of the first floorboard comprises a plastic material and a core of the second floorboard comprises a plastic,
- wherein at least said second edge is flexible, wherein said second edge includes a calibrating groove adjacent said locking groove,
- wherein the calibrating groove is open towards the locking groove, and
- wherein the calibrating groove being adapted to allow the second edge to be pushed towards a sub-floor on which the floorboards are adapted to be arranged to a position wherein the tongue can enter into engagement with the tongue groove.
