Abstract

Process and apparatus for producing packs (10) with a wrapper (12) which is provided with glue locations in the region of folding tabs and walls. For the task of providing wrappers (12) for articles, in particular pack groups (29), consisting of paper or similar materials, folding tabs, closure tabs and walls are to be connected to one another by glue. The blanks for the wrapper (12) are severed from a continuous web (24). Glue locations, namely glue strips and glue patches, are applied onto the web (24) by a fixed glue unit (41) during a conveying movement. The glue used is a hot-melt material which hardens after being applied onto the web (24) and is activated by heat in the region of folding units, in particular of folding turrets (30), and in the region of a pack tower (36).
