Floor panels which are provided with a mechanical locking system including an extruded flexible tongue in a sidewardly open groove which during a vertical folding motion is bent horizontally. A tongue adapted for being received in a sidewardly open groove of a floor panel, wherein the tongue, which is an elongated extruded section, when received in the groove is bendable in a plane substantially parallel with a front face of the floor panel, such that the tongue is at least partially resiliently displaceable inside said sidewardly open groove in said plane during locking of the floor panel with another floor panel and wherein a vertical protrusion, serving as a friction connection between the tongue and the groove, is arranged at an upper or lower part of the tongue, wherein a total width of tongue varies in a longitudinal direction of the tongue.

A set of panels for covering floors, ceilings or walls is disclosed. Specifically, sets of panels including a plurality of panels joined with a mechanical locking at their adjacent edges. Each of the panels includes at least two pairs of parallel side edges. When the panels are installed in rows, the adjacent edges of two adjacent panels in one row are locked to one another and the adjacent panels of the adjacent rows are locked to one another. Locking provides connecting while preventing movement spacing the locked panels apart in a direction perpendicular to the coupled side edges by a translation in the plane of the bottom surface of the panels, and preventing movement spacing the locked panels apart in a direction perpendicular to the coupled side edges by a translation in a plane perpendicular to the bottom surface of the panels.
