Abstract

Verfahren zum Betreiben eines Saugbandvorschubmechanismus, der einen Überdrucklufttrennvorrichtung (40) haben kann, während der Zeit eines Zyklus, in dem kein Vorschub stattfindet, um einen Bogen von einem Bogenvorratstapel (15) zu trennen, wobei das Verfahren Rütteln der obersten Bogen im Stapel (15) durch Aktivieren der Unterdruckluft und/oder der Überdrucklufttrennvorrichtung (40) während der Zeit des Zyklus, zu der kein Vorschub stattfindet, aufweist.

Figure 00000001
A method of operating a suction belt feed mechanism, which may have a pressurized air separator (40), during the period of a no-feed cycle to separate a sheet from a sheet supply stack (15), the method of shaking the top sheets in the stack (15 ) by activating the vacuum air and / or the overpressure air separation device (40) during the time of the cycle at which no feed takes place.
