Abstract

Selon l'invention, on comprime un produit métallique d'épaisseur ≦1 mm entre un relief allongé étroit (2,3) et une succession de reliefs (10) et de creux (11) alternés disposés en face de ce relief étroit (2,3), les dénivellations entre lesdits reliefs (10) et creux (11) alternés étant transversales par rapport audit relief étroit (2,3) et l'effort de compression étant tel que les épaisseurs minimales dudit produit métallique après compression soient comprises entre 0,01 et 0,15 mm. Ce procédé permet d'obtenir des lignes de déchirement sans aspérités blessantes.
L'invention concerne aussi les produits obtenus, elle est particuliè­ rement intéressante dans le domaine de l'emballage. According to the invention, a metal product of thickness ≦ 1 mm is compressed between a narrow elongated relief (2,3) and a succession of alternating reliefs (10) and recesses (11) arranged opposite this narrow relief (2 , 3), the differences in level between said alternating reliefs (10) and recesses (11) being transverse with respect to said narrow relief (2,3) and the compression force being such that the minimum thicknesses of said metal product after compression are between 0.01 and 0.15 mm. This process makes it possible to obtain tear lines without injurious asperities.
The invention also relates to the products obtained, it is particularly advantageous in the field of packaging.
