Beschreibung
Zusammenfassung:	A suction belt feed unit is used in printing machines to aid in the stacking of printed sheets. A main belt feed system transfers sheets of paper to the suction unit that has a belt (8) that passes around a roller (10) at one end and has suction elements (15) at the other. As the sheets are deposited singly on the surface of the belt, the suction effect provides braking. The suction elements in the end section are moved by an eccentrically mounted roller. Sheets are transferred (5) onto the stalk (6). ADVANTAGE - Positions sheets accurately on stack.
