The slab has three independent parts such as a blade (1), a plastic or metal base (2) and cross-piece (3), where the plastic or metal base is sandwiched between the cross-piece and the blade. The cross-piece is directed transversely with regard to the blade, and the blade, base, and the cross-piece are assembled mechanically by a set of fasteners (4) such as staple type fasteners. The cross-piece is directed perpendicular to the blade, and is provided in contact with the blade. An independent claim is also included for an assembly for manufacturing a slab. |
