PROCESS FOR LAMINATING ALUMINUM SHEETS AND ALUMINUM SHEETS OBTAINED BY THIS PROCESS

摘要

This is a process for laminating aluminum foils comprising the steps of: a) ab) providing a first and a second veneer (1, 2) comprising, each one, two overlapping aluminum sheets between which a lubricant is interposed; c) lubricate one side of a veneer between the first and second veneers; d) couple the first veneer with the second veneer,getting a double veneer, where - d?) the lubricated face is a contact face between the first and second veneers, or where - d ??) the lubricated face is a non-contact face between the first and second veneers, where are in this case, provided the intermediate steps of - - d ???) roll the double veneer, obtaining a double rolled veneer (13) comprising no coils; ±) partially separate the double rolled veneer (13) by unwinding,for a coil, both aluminum sheets from one of the first and second veneers, obtaining an at least partially curled double veneer (18) comprising an end portion (19) consisting of a respective portion of both aluminum sheets of only one of the first veneer and the second veneer; - - d ?????) unwind the double veneer (18) at least partially curled,getting a double veneer; e) laminate the double veneer; f) separate the double veneer,obtaining two aluminum sheets (4, 5) who have, each one, both opaque faces and two aluminum sheets (6, 7), that has, each one, an opaque face and a luminous face.
