Abstract: Inner wrappings (20) for cigarette groups (21) or the like, as part of the pack, should be as effectively sealed against aroma and moisture losses as possible. For this purpose, side tabs (34, 35) for forming side walls (27, 28) are connected to one another in a sealed manner in the region of overlapping strips (37, 38), to form a bonding strip (36). The bonding strip (36) extends over part of the height or length of the inner wrapping (20), so that an opening flap (29) can be freed from the inner wrapping (20).

Abstract: For supplying a sufficient quantity of prefabricated blanks (21) to packaging machines (20), blank stacks (22) are brought up to the packaging machine (20) on a stack pallet (25). By the use of at least one stack conveyor (27), the blank stacks (22) are taken off from the stack pallet (25) in succession and conveyed to a blank magazine (23) of the packaging machine (20).

Abstract: For supplying sheet-like material to packaging machines and other processing machines, a rotating circular conveyor (32) is installed within a production or packaging plant. Reel carriers (34) rotate continuously in its conveying rail (33). Reels are automatically picked up in the region of a loading station (36, 36a, etc) and, after rotation about a vertical axis, are automatically taken off from the reel carrier at an unloading station (71) by being stripped off.

Abstract: For testing cigarettes, a test head confronts end faces of the cigarettes. Light beams emitted by a light transmitter are transmitted through those cigarettes having a tobacco deficiency. The transmitted light exits from sides of the defective cigarettes and is received by a transversely arranged receiver responsive to light transmitted through the cigarette paper.

Abstract: In order to separate out defective cigarettes (29) in an economical way, cigarettes are tested in the region of magazine shafts (11a, 11b, etc.; 12a, 12b, etc.) of a cigarette magazine (10). The defective cigarettes (29) identified are conveyed beyond a lower main pushing-out plane (22) and are separated out below this. For this purpose, supporting members (carrying webs 32) for the cigarettes are movable up and down at the bottom end of the magazine shafts.

Abstract: In the production of packs, especially hinge-lid packs, from rigid packaging material (thin cardboard), hitherto individual blanks have been supplied in stacks and introduced into the packaging machine in succession. To make the handling of the blanks easier and to increase the storage capacity, the blanks (23) are now connected to one another via residual connections (25) into a continuous web of material (24) wound as a reel (30). Within the packaging machine, the blanks are severed from the web of material (23) in succession, specifically as a result of the elimination of the residual connections, preferably by being torn off. The residual connections (25) are formed in a region of the blanks (23) or in the region of folding tabs of the latter which, in the finished pack (hinge-lid pack), are concealed by other folding tabs, that is to say are on the inside.

Abstract: Hinge-lid packs consisting of a pack part (11) and a hinged lid (12) articulated on said pack are well known as cigarette package. The hinge-lid packs have the standard international dimensions. For pack contents (cigarette group 10) which do not entirely fill the interior space of the hinge-lid pack a large-area projection (28; 40, 41) is disposed in the region of a pack rear wall (14) and/or a pack front wall (16). Said projection projects into the interior of the hinge-lid pack and rests against and provides support for the pack's contents (cigarette group 10). The projection (28; 40, 41) can be produced by means of embossing or by folding.

Abstract: The testing of cigarettes before their packaging is appropriately carried out in the region of magazine shafts (13, 14) of a cigarette magazine (10). To bring a layer (38) of cigarettes of a cigarette group (16) into an exact position for carrying out testing, they are temporarily received in a transverse slide (29) which causes the cigarettes to be aligned as a result of a transverse movement.

Abstract: In the production of packs (10), especially cigarette packs, it is necessary to allow glue spots for bonding folding tabs together to set or harden sufficiently before the packs are discharged from the packaging machine. For this purpose, the packs (10) are introduced temporarily into a drying turret (13).To ensure that the drying turret (13) has a large a capacity as possible, it is equipped with pairs of two drying pockets (25, 26) located next toone another, such pairs of drying pockets (25, 26) being distributed at a short distance from one another along the periphery of the drying turret (13), specifically in a plane which differs slightly from the radial plane. During the pushing of the packs (10) into and out of the drying pockets (25, 26), closing stamps (40) or revenue stamps (41) can be attached.

Abstract: To transfer reels (11) to supporting journals (15, 16) of a reel-changing device (12) of a packaging machine (10), the supporting journal (15) is axially displaceable. As a result, the reel can be delivered in the working plane or run-off plane without any transverse displacement and held in the receiving position, while the supporting journal (15, 16) penetrates into a central orifice (42) in the reel (11) as a result of axial displacement.

Abstract: In order to control the pressing-on time of sealing jaws in the sealing of folding tabs consisting of sealable packaging material, a cam element, of which the cam part or cam body 17 has a cam recess 20 of irregular shape, is used. A sensing member (tracer roller 16) is adjustable relative to the cam element as a function of the working speed of an associated packaging machine, so that different regions of the cam element which guarantee an always constant pressing-on time of sealing jaws 12 take effect.

Abstract: A packaging machine for simultaneously producing cigarette packs in two parallel production tracks. Each track comprises a cigarette magazine, a feeding conveyor, a folding turret, a drying turret and a discharge conveyor which feeds a transverse path common to both tracks. The turrets and conveyors of each track are mounted on opposite sides of a supporting stand with the magazines and conveyors being transversely offset relative the mid-plane of the machine so that the cigarettes of the two tracks are always arranged, fed and discharged in the same orientation of the cigarettes.

Abstract: Inner wrappings (20) for cigarette groups (21) or the like, as part of the pack, should be as effectively sealed against aroma and moisture losses as possible. For this purpose, side tabs (34, 35) for forming side walls (27, 28) are connected to one another in a sealed manner in the region of overlapping strips (37, 38), to form a bonding strip (36). The bonding strip (36) extends over part of the height or length of the inner wrapping (20), so that an opening flap (29) can be freed from the inner wrapping (20).

Abstract: A pack consisting of a shell (10) and a slide (11) and intended for receiving cigarettes (cigarette blocks 12, 13) has an octagonal cross-section of the shell (10), with longitudinal edges (27) which each consist of two individual edges (28and 29) joined to one another by means of a strip of material (30) going across the angle. As a result, side tabs (16, 17) of the slide (11) have less width, and there is a corresponding saving of material.

Abstract: In (cigarette) packs, sealing and consequently aroma and moisture preservation are unsatisfactory, particularly because of a lack of sealing of an inner wrapping (tin foil blank 13). With the external appearance and constructive design of a (soft-cup) pack being maintained, the inner wrapping is sealed off by means of bonding strips in specific regions of the overlap or fold. Of particular importance here is a bonding strip (23) in the region of a continuous longitudinal overlap 20 which ensures a considerable increase in leak-proofing.

Abstract: An inner wrapping for cigarette shoulder boxes is designed in such a way that, on the one hand, maximum moisture and aroma retention is guaranteed, but on the other hand the design of the inner wrapping is in keeping with processing by machine and favorable handling. The upper wall of the inner wrapping (25) is provided with an extraction orifice (28) which leads up to one of the ends of the cigarettes (24) and which is covered by a closing flap (35) which in the closed position covers the edge regions of the orifice.

Abstract: Hinge-lid packs for cigarettes or other pack contents are very expensive in respect of material consumption. A saving of material is achieved as a result of bevelled longitudinal edges (26,27) and lid longitudinal edges (28,29), while preserving the storage capacity, because, in particular, side tabs (31,32) and lid side tabs (33,34) of the side wall (13) and of the lid side wall (18,19) are made with less width and hence save material.

Abstract: For the easier removal of the contents, particularly of cigarettes (32), of a flip-top packet, fold lines are pre-shaped (central fold line 33, continuation fold lines 35, 36) in the region of a front wall (13) and of a collar front wall (29) in a manner such that by application of pressure via side walls (21) the front wall (13) with the collar front wall, when the flip-top packet is open, are brought into a position which is V-shaped in cross-section.

Abstract: In the packaging of cigarettes and similar articles, it is necessary to test for proper formation, in particular for a sufficient tobacco content. This test is preferably carried out in the region of shafts 12 or shaft groups 15, 16 of a cigarette magazine 11. A test block 38 with test plungers 39 takes effect at one end of the cigarette (tobacco side). On the opposite side, grab members for each tested cigarette are provided, in particular needles 41 the points 42 of which penetrate into the cigarettes or into a filter 43 of the latter. The defective cigarettes are drawn out of the group by retracting the needles.

Abstract: Packaging machines have to, on the one hand, achieve high levels of output but, on the other hand, take into account the sensitivity of the cigarettes to mechanical stresses. A two-track configuration of the packaging machine doubles the output at a given speed (number of strokes). By the special designing of a cigarette magazine (26) in conjunction with a group turret (28), it is accomplished that the formation of cigarette groups (21) and the insertion into the pockets (64) of the group turret (28) can be performed within adequately set stroke times at a high output of the packaging machine.
