Abstract

An article over which a moulding is to be made, aid moulded-over article comprising a base 2 having a top surface 6 and a bottom surface 4, hooks 3 extending from the bottom surface 4 of the base and metallic material fixed on the top surface of the base, the hooks 3 being disposed in a region in the form of a longitudinal strip, the base is flat in shape, the hook strip has a width less than 12 mm, preferably between 3 and 10 mm, and the flat base 2 is of a material such and of a thickness such that it can undergo deformation to follow the shapes of top edges of walls on which the article for moulding over is intended to be placed by its bottom surface

Claims

1. An article over which a moulding is to be made, said article comprising a base (2) having a top surface (6) and a bottom surface (4), hooks (3) extending from the bottom surface (4) of the base and metallic material fixed on the top surface of the base, the hooks (3) being disposed in a region in the form of a longitudinal strip (15), characterized in that the base is flat in shape, the hook strip has a width less than 10 mm, preferably between 3 and 10 mm, and the flat base (2) is of a material such and of a thickness such that it can undergo deformation to follow the shapes of top edges of vertical walls on which the article for moulding over is intended to be placed by its bottom surface.

2. An article for moulding over according to claim 1, characterized in that the hooks (3) are made in the form of longitudinal rows, the number of rows preferably being less than or equal to 3, 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, particularly over a distance of some millimeters, preferably 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, particularly by forming two longitudinal reinforcements on either side of the resin-base interface to provide good anchoring of the foam, and anchoring patterns can also be provided at the outer surface of the metallic resin rib.

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 in the base of which there is made a cavity having walls projecting from the base and on the top edges of which there is intended to be placed an article for moulding over according to claim 1, said article being intended to be fixed to a moulded object by solidification of a foam that is poured there over, characterized in that the cavity has two side walls, preferably parallel, spaced apart by a distance between 4.5 and 12 mm.

9. A method of manufacturing a moulded object according to claim 7, comprising a moulded-over article having hooks projecting towards the exterior of the moulded object, characterized in that it comprises:

a) forming at the base of a mould a cavity comprising two side walls spaced apart preferably by a distance of between 4.5 and 12 mm;

b) placing an article for moulding over according to claim 1 on the outer top edges of the two side walls, the hooks being directed towards the interior of the cavity formed by the two side walls at the base of the mould, then

c) pouring liquid foam into the mould so that it will be fixed on the top surface of the moulded-over article by solidification without being able to penetrate to the interior of the cavity to damage the hooks.

10. A method according to claim 9, characterized in that it consists also in placing the longitudinal end edges of the base on walls of the cavity, particularly two longitudinal end walls, when the article for moulding over is placed on the cavity.

11. A method according to claim 9, characterized in that longitudinal end regions of the base have no hooks, particularly over a longitudinal distance of some millimeters to some centimeters, particularly less than 15 mm.
