ABSTRACT:
An apparatus for erecting flat blanks into three-dimensional box parts has a machine frame, a bin on the frame holding a stack of the blanks with a lower surface of a lowermost blank largely exposed at a base of the stack, an erecting unit on the frame spaced downstream in a transport direction from the bin, and a conveyor on the frame. The conveyor has at least two spaced endless conveyor elements having upper stretches extending horizontally underneath the bin in the direction, respective suction boxes generally level with the upper stretches, and a drive for advancing the elements in the transport direction. An extractor on the frame underneath the bin includes a vertically displaceable vacuum-operated suction head engageable with the lower surface of the lowermost blank for pulling same out of the bin and setting it on the conveyor.
