Abstract
A process for opening folded proof sheets, particularly for their positioning on the conveyor plate of a thread stitching machine, involves moving a stack of the proof sheets along devices which separate the individual sheets until they reach the point where they are all opened. The separating devices comprise blown air suction plates which cause the free outer corner of the adjacent sheet to be drawn up by the suction effect of air jets and thus separated from the rest of the stack. The portion of the sheet which was separated is then guided away from the next blown air suction plate to permit the next proof sheet to be opened.
