Abstract
A vastly improved folder/gluer is disclosed. This folder/gluer: is much more reliable, produces better folds, runs faster, and can be modified much easier, than prior art folder/gluers. These features are achieved by using a vacuum conveyor with overhead folding elements. Furthermore, the top of the article to be folded is never touched by another conveyor.
