Method and installation for manufacturing a floor covering product and floor covering product obtained hereby

1. A method for manufacturing a floor covering product, said method comprising the steps of:

forming a single- or multilayered substrate by extruding of synthetic material-based material in a layer shape;

laminating at least one continuous film to said substrate;

impressing said at least one continuous film using a roller being provided with a relief on its surface;

wherein the substrate and said at least one continuous film form a material web, and that this material web is bent around said roller as the at least one continuous film is impressed by the roller, the substrate being located radially away from the relief of the roller and the continuous film being radially closer to and facing the relief, such that the cooperation between the relief and the at least one continuous film takes place at least over an arc-shaped part;

wherein at least the continuous film, when bent around said roller, is subjected to bending having a radius of 40 cm or more;

wherein said at least one continuous film comprises a decor layer and that this film, prior to laminating, is subjected to controlled stretching in order to stretch the decor to a greater or lesser extent, in the width and/or length, such that the decor is adjusted in function of the desired final result.

2. The method according to claim 1 , wherein the synthetic material is selected from following materials consisting the group of: polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PET) and polyurethane (PUR).

3. The method according to claim 1 , wherein the at least one continuous film comprises a printed film.

4. The method according to claim 3 , wherein the impressions are in register with the décor.

5. The method according to claim 1 , wherein the roller is applied with, seen along the circumference, at least two segments, which each are provided with a relief, wherein in circumferential direction the distance between at least two of these segments is adjustable in order to change the “repeat” with which the impressions are realized.

6. The method according to claim 1 , wherein the material, which is moving along with the roller, of the material web is maintained in contact with the roller at least for 3 seconds.

7. The method according to claim 1 , wherein the material web is supplied to the roller in a heated condition and that the roller is cooled.

8. The method according to claim 1 , wherein the floor covering product is provided with a translucent wear layer.

9. The method according to claim 1 , wherein the substrate is a multilayered substrate.

10. The method according to claim 1 , wherein the continuous film has one or more of the following characteristics:

a thermoplastic synthetic material film;

a PVC film, PU film, PP film, or PET film;

an oriented polypropylene film; and

a hard PVC film on the basis of PVC without plasticizer or with an amount of plasticizer of less than 5 percent by weight.

11. The method according to claim 1 , wherein the impressions are provided in the upper side of the floor covering product in the same continuous process after laminating the continuous film onto the substrate.

12. The method according to claim 1 , wherein the lamination is applied by a belt press.

13. The method accordingly to claim 1 , wherein the continuous film is directly adjacent the relief of the roller.

14. A method for manufacturing a floor covering product, said method comprising the steps of:

forming a single- or multilayered substrate by extruding of synthetic material-based material in a layer shape;

laminating at least one continuous film to said substrate;

impressing said at least one continuous film using a roller being provided with a relief on its surface;

wherein at least the continuous film is bent around said roller with the continuous film facing the relief, such that the cooperation between the relief and the continuous film takes place at least over an arc-shaped part;

wherein the substrate and said continuous film form a material web, and that this material web is bent around said roller as the continuous film is impressed by the roller, the substrate being located radially away from the relief of the roller and the continuous film being radially closer to the relief;

wherein the material, which is moving along with the roller, of the material web is maintained in contact with the roller at least for 3 seconds; and

wherein at least the continuous film, when bent around said roller, is subjected to bending having a radius of 40 cm or more.
