ABSTRACT:
Disclosed is a sheet folding module for use in a sheet processing apparatus in which individual sheets are either separated from a continuous web or are stored in the processing apparatus as a stack of separate sheets in a sheet feeding module, and in which the individual sheets are fed along a feed path toward other sheet processing components, with the individual sheets being folded or left unfolded depending on the length thereof. The folding module has at least one buckle chute and a plurality of feeding and folding rollers which cause sheets to be folded which are long enough to be fed into the buckle chute and still remain under the control of a pair of rollers adjacent the entrance to the buckle chute. The buckle chute has a sheet ejecting mechanism which includes a movable back stop means which can be positioned in the path of movement of sheets or withdrawn from the path of movement of streets, and a movable sheet ejecting means which is operable to eject any sheets from the buckle chute which are too short to reach the normal position of the back stop and still remain under the control of the feed rollers.
