PROCESS AND APPARATUS FOR THE STOCKING (STORAGE) OF (PACK) BLANKS AND FOR FEEDING THESE TO A FOLDING UNIT OF A PACKAGING MACHINE

摘要

: (in conjunction with Figure 2) 1. Process and apparatus for the stocking (storage) of (pack) blanks and for feeding these to a folding unit of a packaging machine. 2.1. 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. 2.2. Especially favourable 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. 2.3. 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).
