Abstract
A method and apparatus for nest folding at least one smaller document of a collation while folding larger documents of the collation comprises the steps of: providing a buckle chute folder having a plurality of buckle chutes with one of the buckle chutes including a kicker structure adjacent a buckle chute stop; transporting to the buckle chute folder a collation having documents of at least two sizes; feeding the collation into the buckle chute having the kicker structure; buckling the larger of the documents into a nip of fold rollers as the lead edge of the collation hits the buckle chute stop; bouncing the smaller of the documents out of the buckle chute as the larger of the documents enter the nip of the fold rollers; and completing the first fold of the larger documents with the smaller documents nested within the first fold.
