ABSTRACT:
Process and apparatus for the stocking (storage) of (pack) blanks and for feeding these to a folding unit of a packaging machine. The supply of packaging material to a packaging machine is especially difficult in the processing of blanks made of cardboard. Supply becomes easier if blanks joined together via residual connections are conveyed as a web of material in the packaging machine. Especially favorable storage of blanks (11) connected to one another is possible if the web of material (19) so formed is arranged in a zigzag-shaped manner as a result of oppositely directed folding and the blanks are stacked in this way. The stacks (15) formed can be kept in stock in a space-saving way and fed to an extraction station, in which the web of material (19) is drawn off from the stacks (15) and restored to the extended state. Appropriately, a plurality of stacks (15) is connected to one another, specifically via vertical web portions (23) from one stack to another, to form a continuous web of material (19).
