Abstract: Disclosed are apparatuses and methods for forming films having uniform thicknesses across the entire width of the film. The films are also disclosed. The apparatus for forming the film includes a first nip roller and a second nip roller, each of the first nip roller and the second nip roller being configured to compress the powder as it passes between the first nip roller and the second nip roller and thereby form the film, whereby in the absence of a force counteracting the pressure of the passage of the powder between the first nip roller and the second nip roller the first nip roller is deflected to a greater degree than the second nip roller. Furthermore, the first nip roller and the second nip roller are each associated with one or more eccentric bearings that rotate to apply force vectors to the first nip roller and the second nip roller.
