Also, production methods to form a board material with a dry blend of thermoplastic particles in powder form and fillers in powder form and to apply a surface layer with a hot-hot lamination process to a core including such board material.

A set of building panels, such as floor or wall panels, having a mechanical locking device at opposite first and second edge portions, such as short edges, configured for horizontal locking of similar or essentially identical panels in an assembled position by means of displacement in an engagement direction, such as a vertical direction, of the second edge portion of a second panel relative the first edge portion of an adjacent first panel. The second edge portion has a locking groove configured to receive a locking element of the first edge portion of an adjacent first panel by means of the displacement. An outer portion of the locking element, such as in a horizontal direction transverse the first edge portion, is configured to cooperate with an inner portion of the locking groove for positioning, such as horizontal positioning, respective upper edge portions of the first and second edge portions during assembling.

A flexible, preferably polymer-based, rectangular floor covering element of double-angling type has six sides: a decorative top face and a bottom face, as well as four edges. The first long edge has a first connection profile with a recess at the bottom face and a tongue overhanging the recess. The second long edge opposite the first long edge has a second connection profile with a protrusion at the bottom face and a groove for receiving the tongue of the first profile. The first short edge is equipped with the first profile and the second short edge is equipped with the second profile. When looking at the floor covering element from above the top face, the edges of the floor covering element are arranged in the following order in the clockwise direction: 1) the first long edge, 2) the first short edge, 3) the second long edge and 4) the second short edge.

Provided is a panel including at least one first coupling part. The first coupling part includes an upward tongue, at least one upward flank lying at a distance from the upward tongue and an upward groove formed in between the upward tongue and the upward flank. The side of the upward tongue facing towards the upward flank is the inside of the upward tongue and the side of the upward tongue facing away from the upward flank is the outside of the upward tongue. At least a part of an upper side of the upward tongue is inclined relative to the plane of the panel, such that the upper side of the upward tongue includes a highest point. The upward tongue has a width, wherein the highest point of the upward tongue is arranged less than 50% of the width from the outside of the upward tongue.

The floor or wall panel has a substrate and a top layer applied thereon. The substrate consists mainly of a mineral material. The panel is provided, on at least two opposite edges, with coupling means that allow two such panels to be coupled together at the respective edges, wherein in the coupled state there is locking in the vertical direction perpendicular to the plane of the coupled panels and in the horizontal direction perpendicular to the coupled edges and in the plane of the coupled panels.

Described is a set of panels (1,2), each panel comprising: ⋅ a top surface (5) and a bottom surface (4); ⋅ a first edge (6) and a second edge (7) parallel to the first edge (6), said edges (6, 7) extending between said top and bottom surfaces (5, 4); ⋅ a first groove (10) provided in the bottom surface (4) of each panel, said first groove (10) extending parallel to and along the first edge (6) of the panel; ⋅ a second groove (11) provided in the bottom surface (4) of each panel, said second groove (11) extending parallel to the first groove (10) along the second edge (7) of the panel; ⋅ a locking profile (3) allowing locking a first panel (1) with its first edge (6) to the second edge (7) of a second panel (2), said locking profile (3) comprising a base (16) and at least three protruding rims (17, 18, 19) extending parallel to one another in the longitudinal direction of the locking profile (3), a first rim (17) pressed in the first groove (10) of a first panel (1) and a second rim (18) situated in between the first and third rims (17, 19) of each locking profile (3) and cooperating with a part of the first panel (1) such that a section (13) of the bottom surface (4) of the first panel (1) is clamped between the first rim and the second rim (17, 18) of the locking profile (3), the third rim (19) configured to fit in the second groove (11) of a second panel (2) thereby locking the second panel (2) to the first panel (1), characterised in that at least the second rim (18) is continuous along the entire length of the locking profile (3). Further described is a method of manufacturing the set of panels.
