Apparatus for producing packs with bevelled or rounded longitudinal edges

An apparatus for producing essentially cuboid cigarette packs of the hinge-lid type, with bevelled longitudinal edges, from a blank made of thin cardboard and having regions for forming a pack front wall, rear wall, side tabs for side walls, hinge-lid-wall portions and a bottom wall, said apparatus comprising a shaping punch means (58), movable up and down, for pressing the blank (20) into a vertical pocket (47), open at the top, of a folding turret (46), the pocket (47) and the shaping punch means (58) having corresponding mating shaping surfaces in the form of a pocket bottom (62) and a punch plate (59), respectively, which have bevelled regions at their sides, such that, simultaneously, side tabs (25,33) are erected and the bevelled longitudinal edges (38,39) are formed between the rear wall and the side walls;

• said shaping punch means (58) having on its radially inner end an upright pressing leg (86) which presses a vertical blank leg (45) into an upright position relative to a horizontal blank leg (44), said vertical blank leg (45) containing the bottom wall (22) and the front wall (21) with its side tabs (24), and said horizontal blank leg (44) containing the rear wall (23) and the hinge-lid wall portions (30, 31, 32, 33, 34, 35, 36);
• and radially-movable side tab former means (88) for folding the side tabs (24) into a position transverse relative to the upright front wall (21), thereby forming the bevelled longitudinal edges (37) between the front wall and the side walls.
