A box (1) for a pack of cigarettes has the shape of a hollow body dimensioned to receive a pack of cigarettes, the hollow body being delimited by at least four surfaces (2, 3, 4, 5) forming the walls of the body and a surface (6) forming a bottom constituted by a prolongation of one wall of the body and connected to that one wall by a bend line (7). The surface (6) forming the bottom of the body is prolonged by a flap (8) connected to the surface forming the bottom by a bend line (9) permitting ...

A method of forming groups of cigarettes, each group being defined by at least one layer of cigarettes arranged side by side. The layer is fed continuously at a given speed and by means of a conveying seat along a given annular path extending through an unloading station. At the unloading station where the layer is transferred from the seat to a group forming pocket (6) by orienting the seat with respect to the path as a function of the relative position of the seat and the pocket (6) at least a...

An installation for manufacturing and packaging cigarettes consists of a production station (10) and a packaging station (11). The production station (10) consists of a plurality of, especially two, manufacturing machines (12, 13) positioned in a special way in relation to one another. The cigarettes produced by the two manufacturing machines (12, 13) are processed by a common packaging machine (14), in order to produce cigarette packets.

A method of checking cigarettes, whereby cigarettes are fed in steps along a gravity channel in the outlet of a hopper, and are successively arrested substantially at a checking station where a checking device determines the density of the open ends of the cigarettes and emits at least one control signal indicating the density; and the control signal is optimized by determining the position of the cigarette in the checking station with respect to the checking device.

Individual assembly of cigarettes from cut tobacco and preformed cigarette paper tubes is facilitated by providing charges of cut tobacco in cartridges. An extension in the form of a hollow tube is provided at one end of the cartridge to enable the sheath enclosing the tobacco to be removed and the tobacco discharged into the paper tube. Specific equipment to effect the assembly also is described.

When testing the cigarettes (10, 11) of cigarette groups (16, 17) in pockets (13, 14) of a conveyor, particularly a cigarette turret (12), difficulties relating to adequate spacing of the testing members (29 . . . 32) from one another arise when the cigarettes (10, 11) have an especially small diameter. In order to make undisturbed testing by means of moving the testing members (29 . . . 32) near to the end faces of the cigarettes (10, 11) nevertheless possible, these are tested successively in ...

The supply of web-like packaging material to high-performance packaging machines has hitherto involved a high outlay in terms of labor. The packaging material in the form of reels (13) has to be fed to the packaging machine conveyed up to a working journal (11, 12). Manual involvement has hitherto been needed for this. However, according to the Disclosure, the fully mechanical transfer of reels (13), from a reel stock (15) to one of two working journals (11, 12) a transport journal (20) mounted ...

Filter tipped cigarettes are produced by dividing a continuous tobacco stream into alternate sections having respective lengths corresponding to a double cigarette filler and a double filter portion. The double filter portion sections are removed from the stream to leave spaced double filler sections which proceed to a position where double filter portions are inserted in the gaps left by the removed sections. The stream of alternating tobacco sections and filter portions is continuously wrapped...

A device and method for loading a cartridge with pre-formed tubular wrappers for cigarette manufacture. The device provides for dispensing pre-formed tubular wrappers from a container to a cartridge without directly touching the wrappers.

Cigarettes are made with a filler comprising an outer annulus of tobacco surrounding a core of a tobacco or other material different from that in the outer annulus. The annulus tobacco is showered onto a conveyor to form a layer which is then bent into a U-section. Core material is fed into the longitudinal recess in the layer, after which further tobacco is showered on to the layer plus core to enclose the core in tobacco the core may be formed by showering the core material onto a separate con...
