Abstract
A housing, having therein only one, driven, rotatable drum, receives sheet paper for in-folding or Z-folding, selectively. Abutments, within the housing, delimit travel of the leading edge of the paper, causing the paper to buckle, there behind, and form a nip or fold; the latter is directed between the drum and a guide to one of the abutments, causing the paper to fold again. Then the fully folded paper is discharged from the housing. One of the abutments is retractable, to accommodate a Z-fold, or extendable to enable an in-fold.
