Abstract: Systems and methods are provided herein for removing alternate material from a foil while minimizing the amount of alternate material particles that are deposited on the surface of an active material. For example, a web may comprise an active material on a first portion of a foil and an alternate material on a second portion of the foil. One or more brushes may be used to remove the alternate material from the second portion of the foil. As the one or more brushes remove the alternate material from the second portion of the foil, a vacuum may be used to capture the alternate material that is removed from the second portion of the foil. In such an example, the resulting web no longer has alternate material on the second portion of the foil and has reduced alternate material particles on the surface of the active material.

Abstract: Systems and methods are provided herein for applying sacrificial material to otherwise uncoated areas of a foil to provide uniform pressure during calendering. For example, one or more portions of a foil may be coated with an active material while other portions of the foil may be coated with an appropriately selected alternate material. After the active material and the alternate material are applied to the foil, the foil may be dried and then calendered. During calendering, the compressive force of the rollers can cause the portion of the foil coated in the active material to stretch a similar amount to the portions of the foil coated in the alternate material. The resulting calendered web has minimal wrinkles due to the similarity of the stretching of the foil coated in the active material and the foil coated in the alternate material.
