Abstract
Abstract Apparatus for generating layers on a carrier film wherein a plurality of glow polymerization layers and intervening metal layers are applied to a carrier foil 3 on a continuous process. The carrier foil is passed over a drum 4 and conducted through a first vacuum system wherein glow polymerization electrodes apply glow polymerization layers to the foil then the foil passes through a vacuum lock into a second vacuum chamber wherein a metallization device 10 is situated so as to apply a metallization layer. Then the foil passes through a second vacuum lock to the first vacuum chamber wherein a second polymerization layer is applied over the metallization layer. A diaphragm strip 19 also passes over the foil and is continuously used during the polymerization and metallization steps.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
189 words
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.

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.
Claim 3
Dependent Claim
131 words
A device according to claim 1, characterized in that, for covering the parts of the foil not to be coated, at least one continuous screening belt strip is provided in the first and second vacuum chambers and such belt strip is conducted so it is moving around the cylinder in the area of metal coating and polymerized layers; and said belt strip is mounted in the second vacuum chamber which containing the metallization device can be moved to two positions which are laterally displaced with respect to each other, with each allocated to one rotary direction of the cylinder and said belt strip mounted in the first vacuum chamber is always moved in a lateral direction which lies between the two positions of the belt strip in the second vacuum chamber.
Claim 4
Dependent Claim
43 words
A device according to claim 2, characterized in that two screening belt strips are mounted in the first vacuum chamber to move around the cylinder in the area of one polymerization segment (5) and forming closed loops surrounding the respective rollers (2, 12).
Claim 5
Dependent Claim
66 words
A device according to claim 2, characterized in that the polymerization means include two glow electrodes in the first vacuum chamber, said glow electrodes partially enclosing the cylinder in the form of concentric ring segments and extending between respective vacuum locks and a deflection roller for the removal or, respectively, the application of the foil; and in said glow electrodes being narrower than the carrier foil.
