A floor panel with a substrate and a decorative layer of wood veneer with a thickness of 1 millimeter or less and provided on the substrate. The decorative layer is provided on the substrate by means of a glue layer which is situated between the substrate and the decorative layer. The glue layer comprises hard particles with an average particle size which is at least one third of the thickness of the wood veneer. Methods for manufacturing such floor panels are provided.

A method and device for inserting a tongue in an insertion groove in a panel. The method includes displacing a first tongue to an end position of a tongue queue, which comprises tongues under compression, in a tongue queue device, compressing the first tongue, displacing the tongues in the tongue queue by compression forces from the tongues under compression, displacing a second tongue, which is at a front position of the tongue queue, to an inserting device, displacing the second tongue into an insertion groove in a panel by said inserting device.

A set of subfloor panels including a joint configured to be glued is provided. The joint includes a tongue at a first edge of a first panel and a tongue groove at a second edge of a second panel. The tongue and the tongue groove are configured for positioning of the first panel relative to the second panel in a vertical direction, wherein a lower lip of the tongue groove extends beyond an upper lip of the tongue groove. An element protrudes from the lower lip and an underside of the first edge includes an element groove. The element and the element groove are configured for positioning of the first panel relative to the second panel in a horizontal direction. The lower lip includes a first impact surface, and the first edge includes a second impact surface. The first impact surface is configured to cooperate with the second impact surface.

Building panels provided with a mechanical locking system including a tongue, at first edge of a first building panel, cooperating with a tongue groove, at a second edge of an adjacent second building panel, for vertical locking of the building panels and a method for producing such building panels. The method includes the step of forming the tongue of material of the first edge. The insertion groove may have a sidewall at a third edge, which is adjacent the first edge, and may be open at a fourth edge, which is opposite the third edge.

A set of subfloor panels including a joint configured to be glued is provided. The joint includes a tongue at a first edge of a first panel and a tongue groove at a second edge of a second panel. The tongue and the tongue groove are configured for positioning of the first panel relative to the second panel in a vertical direction, wherein a lower lip of the tongue groove extends beyond an upper lip of the tongue groove. An element protrudes from the lower lip and an underside of the first edge includes an element groove. The element and the element groove are configured for positioning of the first panel relative to the second panel in a horizontal direction. The lower lip includes a first impact surface, and the first edge includes a second impact surface. The first impact surface is configured to cooperate with the second impact surface.

A set of essentially identical floorboards each including a front face and a rear face extending in the horizontal plane, a core, and a surface layer, a mechanical locking system is arranged at least at two opposite edges for connecting a floorboard with an adjacent floorboard in a horizontal and a vertical direction, said mechanical locking system being configured for connecting the floorboard with the adjacent floorboard by vertical folding, wherein one of said opposite edges is provided with a horizontally extending protrusion at an upper edge, and wherein said protrusion is configured to overlap a surface groove at an upper edge of the other of said opposite edges, such that two connected and adjacent floorboards have upper overlapping edges.

Floor panels are shown, which are provided with a mechanical locking system including a flexible tongue in a displacement groove. The flexible tongue may be formed from the core material of the floor panels and inserted during production into the displacement groove. The locking system may be locked with vertical folding.

A panel for wall-, ceiling- or floor coverings is provided, the panel comprising an upper side, a lower side, and front ends, defining a circumference of the panel in the installed state, and at least one front end is protruded with respect to the circumference by a detachable protruding lip formed at the lower side, one horizontal locking groove at the lower side, characterized in that the protruding lip has a predetermined break-off surface. Furthermore, methods are provided for manufacturing wall-, ceiling- and/or floor coverings comprising or consisting of a plurality of the panels.

A set of essentially identical panels, such as building panels, provided with a mechanical locking system including a displaceable tongue arranged in a displacement groove having a first opening at a first edge of a first panel. The tongue is configured to be displaced in the displacement groove along a displacement axis to attain a locking state wherein a first portion of the tongue cooperates with a first tongue groove having a second opening at a second edge of an adjacent second panel, for vertical locking of the first and the second edge. A second portion of the tongue is configured to cooperate with the second edge of the adjacent second panel via an elongated element for vertical unlocking of the first and the second edge.

Ceramic and stone tiles are shown, which are provided with a locking system including a separate strip part connected to vertical and horizontal grooves formed in the tile edge. A set of ceramic or stone tiles including a first tile provided with a first edge and a second tile provided with a second edge wherein the tiles are provided with a locking system for locking the first edge to the second edge in a horizontal direction parallel with a tile surface and in a vertical direction perpendicular to the horizontal direction, said locking system includes a first and a second tongue and a strip part provided with a first and a second locking element.
