The disclosure relates to a method for producing an extruded sheet, which includes: a) providing calcium carbonate (CaCO) powder; b) providing polyvinyl chloride (PVC) powder; c) providing additives as stabilisers; e) heating the mixture until the PVC softens to form a kneadable mass and the CaCOat least partially bonds to the PVC; f) cooling the mass; g) conveying the mass to an extruder; h) melting and extruding the mass by means of an extruder and moulding into a sheet by means of a slotted nozzle; i) pressing the still-warm sheet to a desired final thickness by means of at least two calendar rolls; and j) at least one layer of a pigmented lacquer is applied to the upper side; and k) an additional lacquer is applied to the pigmented lacquer to increase the scratch resistance.

Method for producing an extruded sheet

The disclosure relates to a device for locking two interconnected floor panels that are identically embodied and includes a core, an upper side and a lower side, and a first lateral edge (I) and a second lateral edge (II) opposite the first lateral edge. On the upper side, the first lateral edge (I) of the first floor panel abuts against the second lateral edge (II) of the second floor panel. A horizontal groove extending into the core is embodied in the second lateral edge (II), with an upper wall, an inner wall and a lower wall, the lower wall being formed from a lower lip projecting on the first lateral edge (I), which, on the outer end thereof, has a projection that is oriented towards the upper side and has a first locking edge, and at least one locking element is inserted in the region of the connection point of the two floor panels. An outwardly projecting spring is provided on the second lateral edge (II), and includes a step forming a spring tip on the outer end thereof, and on the end thereof facing the core, a second locking edge extending in the vertical direction (V), the locking edge being the outer wall of a vertical groove open towards the lower side, in which the projection engages. The locking takes place, in the vertical direction, by means of the spring tip engaging in the horizontal groove, and in the horizontal direction, by means of the locking element supported on the first locking edge of the projection and on the second locking edge of the spring. The disclosure is characterised in that the locking element is compressible in the vertical direction (V) and not compressible in the horizontal direction.
