MECHANICAL STRIPPING OF SACRIFICIAL LAYER

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.
