DE LA RUE GIORI S.A. LAUSANNE/SWITZERLAND ABSTRACT SHEET-FEEDER The sheet-feeder (B), designed as a buffer store, has a magazine (24) for receiving vertically stacked sheets and having a base (26), which leaves free an edge strip (R) of the sheet stack (S). Along this edge strip there moves an endless belt (18), articulated on which are separating elements (1), provided with a curved suction surface, followed by a plurality of spacers (11). The edge strip of the lowermost sheet is bent away downward from the remaining stack as it is sucked against the curved suction surface, and has the following spacers engage over it, on which the remaining stack is supported. After passing of a separating element by the edge strip, this edge strip bears against the undersides of the spacers, bent away completely from the remaining stack. From this position, in which the endless belt (18) is briefly at a standstill, the edge strip is fed by adjustable suction heads (31) to a conveyor belt (35), the grippers (37) of which draw the lowermost sheet out from underneath the stack and transport it away.
