On a buckle folder, the sheet is laid fl at on a feed table and then enters the fold plate assembly where it comes to
a stop against the stationary sheet stop. A series of buckles then forms throughout the sheet. The buckles within
the fold plate are kept very small by the narrow channel design.
The buckles at the end of the fold plate, however, will be larger. The fold plates and fold rollers are confi gured
such that the large buckle will always form downward, where it can be grabbed by the fold rollers and compressed
into a fold.
In the diagram below, fold plate #1 is angled upwards. Because of this and the confi guration of the fold rollers,
sheets fed into the #1 plate will always be folded up (i.e. so that the “up” surface of the sheet is folded into contact
with itself).
Likewise, because fold plate #2 is angled down, sheets fed into it will be down-folds; the “down” surface of the
sheet will be folded into contact with itself. This diagram shows the plate #2 defl ector in position. In this case, the
sheet does not enter plate #2, and produces a single fold.
