Abstract
Methods for inserting a folded film into another folded film include combining the films without unfolding or folding either of the folded films. In particular, one or more implementations of a method of combining folded films involves directing a first folded film in a first direction and separating first and second halves of the first folded film. The method also involves directing a second folded film in a second direction generally perpendicular to the first direction. Additionally, the method involves inserting the second folded film between the first and second halves of the first folded film. Furthermore, the method involves redirecting the second folded film into the first direction while between the first and second halves of the first folded film.
