ABSTRACT:
A method for controlling an automatic sheet connecting and feeding apparatus in which folded sheets, each of which is folded zigzag in the form of a stack of sheets, are conveyed successively by a plurality of conveying means to a processing means. In order to connect the bottom sheet of a first one of the folded sheets to the top sheet of a second folded sheet following the first folded sheet the top sheet is lifted with a suction device. The step of lifting the first folded sheet includes the steps of pushing the suction device against the top sheet to suction and retain the top sheet, moving the suction device in parallel with the surface of the top sheet and moving the suction device in a direction perpendicular to the surface of the top sheet.
