Abstract
Process and apparatus for forming cigarette packs having rounded or beveled longitudinal edges includes forming the contoured edges on a flat blank at a shaping station as a preliminary shaping step. The shaping station includes a shaping mandrel or plate having rounded or beveled edges and shaping rollers or strips for wrapping the blank about the plate to produce the desired longitudinal edges contours.

Process for producing cigarette hinge lid packages, having a pack part (13) and a lid (14), from one common longitudinally-extending blank (11) with areas for the forming of a front wall (15), a bottom wall (16), a rear wall (17) and narrow side walls from pack side tabs (18, 19) folded over each other, as well as a lid top wall (22), a lid front wall (23), a lid rear wall (21), and lid side walls from lid side tabs (26, 27) folded over each other, characterized by the following steps:
- fixing the spread-out blank (11) in a shaping station (31) by lowering a shaping plate (39, 95) from above onto the blank (11);
- choosing the shaping plate (39, 95) to have the total length of the front wall (15), bottom wall (16), rear wall (17), lid rear wall (21), top wall (22) and lid front wall (23) areas of the blank;
- after lowering of the shaping plate (39, 95) onto the blank (11), moving fixed longitudinally folding rollers (32, 33;
- 100, 101), rotatable about axes extending in the longitudinal direction of the blank (11) while resting against it, from a position below the shaping plate (39, 95) to a position around lateral shaping edges (40, 41 or 96, 97) of the shaping plate, and pressing the blank (11) against the shaping edges (40, 41 or 96, 97);
- and
- selecting the shaping edges (40, 41;
- 96, 97) to be rounded in an arc shape, or beveled.

- after lowering the shaping plate (39, 95) onto the blank (11), moving folding strips (103, 104) from a position below the shaping plate laterally against lateral shaping edges (96, 97) of the shaping plate, while taking along and shaping of the pack side tabs (18, 19) and the lid side tabs (26, 27) of the blank (11);
- and
- choosing the shaping edges (96, 97) to be rounded in an arc shape, or beveled.
