Apparatus for generating layers on a carrier foil

Apparatus for applying layers of polymerization layers and metallized layers to a carrier foil (3) comprising a cylinder supported for rotary motion in these directions, a first roll supplying said carrier foil so that it substantially passes around said cylinder, a second roll receiving said carrier foil in a first direction mounted adjacent said cylinder, a first vacuum chamber extending about said drum, a second vacuum chamber extending about said drum with a metallization device mounted therein, first and second polymerization means mounted in said first vacuum chamber so as to apply a polymerization layer to said foil before and after said metallization, a diaphragm system comprising a continuous screening belt traveling with the carrier foil about said cylinder and for generating lateral displacement of said diaphragm, groups (13, 14) of guidance rollers (15-17) are mounted between the metallization device in the second vacuum chamber and the first and second polymerization means in the first vacuum chamber;

• and control devices which as a function of the rotary direction of the drum, cause a displacement of the guidance rollers (17) of each group that are mounted adjacent the metallization device.
