said central strip region is flat in a transversal direction of the article and has a width measured in said transversal direction;

said right and left ledge regions have respective left and right portions extending parallel to said central flat strip region when said article is placed on top of a cavity and foam is being poured on it, said right and left portions having respective left and right widths in said transversal direction; and

the sum of said left and right portion widths is larger than said width of said central strip region, wherein said left and right widths of said left and right portions solely prevent foam from entering the cavity during pouring of the foam.

2. An article for moulding over according to claim 1, characterized in that the hooks (3) are made in the form of longitudinal rows and the hooks have a Christmas tree shape.

3. An article for moulding over according to claim 1, characterized in that the longitudinal strip (15) comprising hooks stops at a distance from the longitudinal ends of the base, longitudinal end regions (7, 8) thus being formed without hooks over a distance less than 15 mm, to enable the base to be placed at the level of its longitudinal ends directly on the top edges of the walls (13, 14) forming the cavity.

4. An article for moulding over according to claim 1, characterized in that the base is of polyamide 6 and has a thickness of between 0.2 mm and 0.4 mm or the base has a thickness of 0.15 to 0.35 mm and is of polyamide 6-6.

5. An article for moulding over according to claim 1, characterized in that the metallic material is embodied in the form of a metallic resin rib fixed by gluing to the top surface of the base said metallic resin rib including two longitudinal grooves on either side of the resin-base interface to provide good anchoring of the foam.

6. An article for moulding over according to claim 5, characterized in that the resin rib comprises at least 6 g per linear meter of metallic powder for a total weight of metallic resin of at least 10 g per linear meter.

7. A moulded object of foam to which one or more article for moulding over according to claim 1 is fixed by hardening of the foam on the top surface of the base after the foam has been poured in a mould.

8. A mould including a base, the base including a cavity having walls projecting from the base and the top edges of which being adapted to receive an article for moulding over according to claim 1, said article being fixed to a moulded object by solidification of a foam that is poured there over, characterized in that the cavity has two side walls, spaced apart by a distance between 4.5 and 12 mm.

9. An article over which a molding is to be made by pouring foam on it while it is placed on top of a cavity delimited by vertical walls, each having a top surface, said article comprising an element having a central strip region and left and right ledge regions, said element having a top surface and a bottom surface, hooks extending from said central strip region of the bottom surface and magnetically attractable material fixed to said element, wherein said hook strip has a width less than approximately 10 mm, said element includes a material and a thickness such that, when said article is placed on top of the cavity, with the hooks inside the walls and facing the cavity, said bottom surfaces of said ledge regions being in contact with said top surfaces of the vertical walls to provide surface to surface contact between said ledge regions and said vertical walls during the entire foam pour, and said central strip region of said bottom surface, from which said hooks are extending, except said hooks, is the lowest part of the article;

wherein said central strip region is flat in a transversal direction of the article and has a width measured in said transversal direction;

said right and left ledge regions have respective left and right portions extending parallel to said central flat strip region when said article is placed on top of a cavity and foam is being poured on it, said right and left portions having respective left and right widths in said transversal direction; and

the sum of said left and right portion widths is larger than said width of said central strip region, wherein said left and right widths of said left and right portions solely prevent foam from entering the cavity during pouring of the foam.

10. The article of claim 9 wherein said hook strip has a width between approximately 3 and 10 mm.

11. The article of claim 10, wherein said element is flat in shape.

12. The article of claim 10, wherein said magnetically attractable material is fixed on said top surface of said element.

13. The article of claim 9, wherein said element is flat in shape.

14. The article of claim 13, wherein said magnetically attractable material is fixed on said top surface of said element.

15. The article of claim 9, wherein said magnetically attractable material is fixed on said top surface of said element.

16. An article over which a molding is to be made by pouring foam on it while it is placed on top of a cavity delimited by vertical walls, each having a top surface, said article comprising an element having a central strip region and left and right ledge regions, said element having a top surface and a bottom surface, hooks extending from said central strip region of the bottom surface and magnetically attractable material fixed to said element, wherein said hook strip has a width less than approximately 10 mm, said element includes a material and a thickness such that, when said article is placed on top of the cavity, with the hooks inside the walls and facing the cavity, said bottom surfaces of said ledge regions being in contact with said top surfaces of the vertical walls during the entire formation of the moulding to substantially prevent the foam from entering the cavity, and said central strip region of said bottom surface, from which said hooks are extending, except said hooks, is the lowest part of the article;

wherein said central strip region is flat in a transversal direction of the article and has a width measured in said transversal direction;
