Abstract

A lamination apparatus uses pneumatic balancing force(s) to eliminate or reduce unevenly distributed forces applied on the lamination rollers. The lamination apparatus includes a first lamination roller, a second lamination roller positioned parallel to the first lamination roller, and a repositioning device configured to adjust a gap between the first lamination roller and the second lamination roller. The lamination apparatus further includes one or more pneumatic devices configured to apply forces on the first lamination roller and/or the second lamination roller.

Claims (26)

1 . A lamination apparatus, comprising:

a first lamination roller comprising a first rigid axle shaft having two opposite ends fixed on a frame of the lamination apparatus via two respective bearings;

a second lamination roller positioned substantially parallel to the first lamination roller and comprising a second rigid axle shaft having two opposite ends fixed on respective sliders or the frame of the lamination apparatus via two respective bearings;

a repositioning device configured to adjust a gap between the first lamination roller and the second lamination roller; and

one or more pneumatic devices configured to apply pneumatic forces on the first lamination roller or the second lamination roller in a direction that is substantially perpendicular to an axle of the first lamination roller or an axle of the second lamination roller for balancing lamination forces.

2 . The lamination apparatus of claim 1 , further comprising:

at least one wheel coupled to each of the pneumatic devices.

3 . The lamination apparatus of claim 2 , further comprising:

a distribution roller positioned between the pneumatic device and the first lamination roller or the second lamination roller, wherein the distribution roller is in contact with (i) the at least one wheel coupled to the pneumatic device and (ii) the first lamination roller or the second lamination roller during lamination.

4 . The lamination apparatus of claim 1 , wherein:

the pneumatic devices include a first set of pneumatic devices distributed along a length of the first lamination roller and configured to apply forces on the first lamination roller and a second set of pneumatic devices distributed along a length of the second lamination roller and configured to apply forces on the second lamination roller.

5 . The lamination apparatus of claim 1 , wherein:

one or more of: the first lamination roller, a core of the first lamination roller, the second lamination roller, or a core of the second lamination roller, are made of metal.

6 . The lamination apparatus of claim 3 , wherein the distribution roller is a hollow metallic roller.

7 . The lamination apparatus of claim 3 , wherein the distribution roller is a solid plastic roller.

8 . A lamination apparatus for laminating flexible films, comprising:

a first lamination roller comprising a first rigid axle shaft having two opposite ends fixed on a frame of the lamination apparatus via two respective bearings;

a second lamination roller positioned parallel to the first lamination roller and comprising a second rigid axle shaft having two opposite ends fixed on respective sliders or the frame of the lamination apparatus via two respective bearings; and

one or more pneumatic devices configured to apply balancing forces on the first lamination roller or the second lamination roller in a direction that is substantially perpendicular to an axle of the first lamination roller or an axle of the second lamination roller, wherein for balancing lamination forces.

9 . A lamination apparatus, comprising:

a first lamination roller comprising a first rigid cylindrical core;

a second lamination roller comprising a second rigid cylindrical core and positioned parallel to the first lamination roller;

a repositioning device configured to adjust a gap between the first lamination roller and the second lamination roller;

one or more pneumatic devices configured to apply pneumatic forces on the first lamination roller or the second lamination roller in a direction that is substantially perpendicular to an axle of the first lamination roller or an axle of the second lamination roller;

a wheel coupled to each of the pneumatic devices; and

a distribution roller positioned between (i) the pneumatic device and (ii) the first lamination roller or the second lamination roller, wherein the distribution roller is in contact with (i) the wheel coupled to the pneumatic device and (ii) the first lamination roller or the second lamination roller during lamination.
