Abstract
A transfer apparatus for folding boxes including suction heads disposed on a carrier and for holding the folding boxes by negative pressure. To enable adjusting the suction heads to a format of folding boxes to be manipulated, the suction heads have a plurality of cup-shaped suction devices, individual ones of which can be adjusted out of the working position into a position of repose and which can be blocked off from the negative pressure. To this end, the adjustable suction devices are mounted on necks displaceable in carriers, and the necks can be arrested in two positions.
