Abstract:
A process for producing a cigarette pack (11) from at least one thin-walled blank which is to be severed from a continuous, longitudinally extending material web (10) being continuously transported in a direction, the blank having folds (12, 13) running in the longitudinal direction of the material web (10) which form a double-layer border-side folded strip (13) and a continuous Z-fold (12), said process comprising the steps of:a) making the folds (12, 13) of the material web (10) in a shaping section having a beginning and end formed by first (24) and second (28) deflecting rollers, respectively, for the material web (10);b) arranging the first deflecting roller (24) to guide by deflection the non-folded or partially folded material web (10) into the shaping section, and arranging the second deflecting roller (28) to guide the material web (10), provided with the folds (12, 13), out of the shaping section;c) in a first portion of the shaping section following the first deflection roller (24) in the transport direction, shaping the continuously transported material web (10) into an intermediate folded position forming lateral, upwardly directed legs (42, 43) of the web; andd) guiding the lateral, upwardly directed legs (42, 43) of the material web (10) through a shaping subassembly (27) in which the upwardly directed legs (42, 43) form the border-side folded strip (13) and the Z-fold (12) by means of stationary folding elements (46, 47; 50, 52, 53).
