Abstract
Process and apparatus for folding or shaping a continuous material web (10) made of thin packaging material. In this case, the material web (10) is directed through a shaping subassembly (27) which uses fixed shaping elements, namely shaping webs (46, 47 and 50, 52) and a mating web (53), to deform the material web (10) during transportation of the same.
Claims13
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;
- and
- d) 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).
An apparatus for producing a cigarette pack (11) of the soft-pack type 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) which run in the longitudinal direction of the material web (10) and which form a double-layer border-side folded strip (13) and a continuous Z-fold (12), said apparatus comprising:
- a) means for continuously conveying the material web (10) through a shaping section which has a beginning and an end which are respectively defined by first (24) and second (28) deflecting rollers for the material web (10);
- b) means for transporting the material web in the shaping section (10) past a first shaping element (44) for producing lateral, upwardly directed legs (42, 43) of the material web (10);
- and
- c) a shaping subassembly (27),
- d) the material web (10) with said upwardly directed legs (42, 43) being transported through said shaping subassembly (27) which applies the folds (12, 13) to the material web (10) in regions of the legs (42, 43), respectively,
- e) wherein said shaping subassembly (27) has stationary folding elements comprising:
- first (46) and second (47) shaping webs spaced one above the other for making the folding strip (13);
- and
- third (50) and fourth (52) stationary shaping webs spaced one above the other, and
- a mating web (53) which extends into a region between the third and fourth shaping webs (50, 52), for making the Z-fold (12).
