A set of panels including first and second panels. The first and second panels respectively include first and second edges. The first edge includes a locking strip with a locking element configured to cooperate with a locking groove at the second edge for locking the first edge to the second edge. The locking element includes a first locking surface at a first angle from a plane parallel to the first panel surface and the locking groove includes a second locking surface at a second angle from a plane parallel to the third panel surface. The first angle is different from the second angle such that the first locking surface converges towards the second locking surface at a cooperation part in a locked position. The first locking surface cooperates with the second locking surface at the cooperation part.

A panel includes a top side, a bottom side and a first edge extending between the top and bottom side and having a first coupling part; and a second edge extending between the top and bottom side and having a second coupling part. The coupling parts make it possible to produce a horizontal and vertical lock between two such panels by means of a vertical movement of the one panel with respect to the other panel.

A thermoplastic-based building panel, such as a floor panel. The building panel includes an upper layer arrangement, a lower layer arrangement, and a balancing layer provided between the lower and the upper layer arrangement. The building panel further includes a groove arrangement including grooves.

The building panel includes a groove arrangement, wherein a major portion of the grooves therein is provided in the balancing layer only. A thermoplastic-based building panel including a mechanical locking system for horizontally and/or vertically locking the building panel to an adjacent building panel. The mechanical locking system includes a cooperating surface which is situated in a balancing layer and is configured to cooperate with a cooperating surface of an adjacent building panel.

A set of building panels including a first mechanical locking system at respective first and second opposite edges. The first mechanical locking system including at one of the first or second opposite edges a tongue groove configured to receive a locking tongue of the other of the first or second edges, for vertical locking of adjacent essentially identical panels in an assembled position. The locking tongue includes an essentially horizontal and/or upwards-facing upper surface. A second mechanical locking system is formed on respective third and fourth opposite edges. The second mechanical locking system includes at one of the third or fourth edges a wedge groove configured to receive a displaceable locking tongue, for vertical locking of essentially identical adjacent panels in an assembled position. The displaceable locking tongue is configured to displace in a displacement groove provided in the said other of the third or fourth edge.

A method for manufacturing a floor panel with a substrate and a top layer of laminate, which floor panel, at one or more edges, is provided with a lower edge region, where the laminate extends in one piece from the actual upper surface of the substrate over the lower edge region at least up to a point. The laminate surface is situated at a level in a horizontal plane which intersects the substrate and that the substrate material, at the location of the lower edge region, has the same or a lower density than at the actual upper surface of the substrate material.

A set of floor panels, which is suitable for forming a floor covering in herringbone pattern, wherein these floor panels are oblong rectangular; wherein the long as well as the short edges are provided with mechanical coupling means; and wherein the male coupling part on the short edge can be inserted into the female coupling part on the long edge in one and the same turning movement which is used to insert the male coupling part on the long edge into the female coupling part on the long or short edge.

Panels are shown which are provided with a mechanical locking system allowing perpendicular connection with a snap action. A set of panels including a first and a second panel, an edge of the second panel is insertable into a groove of the first panel, when the panels are arranged essential perpendicular to each other, to obtain a mechanical connection between the first and the second panel, when the second panel is displaced essentially perpendicularly to the first panel.

A thermoplastic-based building panel, such as a floor panel. The building panel includes an upper layer arrangement, a lower layer arrangement, and a balancing layer provided between the lower and the upper layer arrangement. The building panel further includes a groove arrangement including grooves. A thermoplastic-based building panel including an upper layer arrangement and a balancing layer which is a bottom layer of the building panel. The building panel includes a groove arrangement, wherein a major portion of the grooves therein is provided in the balancing layer only. A thermoplastic-based building panel including a mechanical locking system for horizontally and/or vertically locking the building panel to an adjacent building panel. The mechanical locking system includes a cooperating surface which is situated in a balancing layer and is configured to cooperate with a cooperating surface of an adjacent building panel.

A panel may include at a substrate and a top layer provided on the substrate. The top layer may include a motif and a transparent or translucent synthetic material layer provided above the motif. The motif may be a print formed by digitally applying inks on the substrate with the intermediary of one or more primer layers extending underneath the print. The transparent or translucent synthetic material layer may include polypropylene and have a thickness of less than 1 millimeter.

A set of essentially identical panels, such as building panels, provided with a mechanical locking system including a displaceable tongue, which is arranged in a displacement groove with a first opening at a first edge of a first panel. The displaceable tongue is configured to cooperate with a first tongue groove, with a second opening at a second edge of an adjacent second panel, for vertical locking of the first and the second edge. The height of the first opening is greater than a second height of the second opening.
