ABSTRACT:
There is disclosed an apparatus for separating sheets at the bottom of a stack comprising two contrarotating suction drum assemblies (14,15:17) and a suction pipe (18) extending between the two assemblies. In order to ensure that the edges of the lowermost sheet are fully separated from the sheet above before the sheet is extracted from the bottom of the stack, one assembly has a central suction drum (14) having suction outlets (25) and the other assembly (17) has suction outlets (29) to draw the edges of the lowermost sheet in their central regions downwardly from the sheet above. Two pairs of contrarotating double ended fingers (32) are mounted on either side of the drum assemblies to enter the stack above the lowermost sheet where the central region has been drawn downwardly and to move along the edges of the stack towards the ends of the stack to separate the edges of the lowermost sheet from the sheet above. The drum assembly (15) has two outer suction drums (15) which rotate at twice the speed of the central drum section ( 14) and have suction ports (33) activated when the fingers (32) have separated the edges of the lowermost sheet to draw the lowermost sheet out of the bottom of the stack.
