Abstract
In the production of packs, especially hinge-lid packs, from rigid packaging material (thin cardboard), hitherto individual blanks have been supplied in stacks and introduced into the packaging machine in succession. To make the handling of the blanks easier and to increase the storage capacity, the blanks (23) are now connected to one another via residual connections (25) into a continuous web of material (24) wound as a reel (30). Within the packaging machine, the blanks are severed from the web of material (23) in succession, specifically as a result of the elimination of the residual connections, preferably by being torn off. The residual connections (25) are formed in a region of the blanks (23) or in the region of folding tabs of the latter which, in the finished pack (hinge-lid pack), are concealed by other folding tabs, that is to say are on the inside.
