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.

In a process for packaging cigarettes by combining them into cigarette groups and wrapping them in a blank of packaging material, wherein a group is conveyed and introduced into a pack pocket of a folding turret, taking with it the blank provided in a plane transverse relative to the conveying direction of the group, and the group is conveyed further, the blank is folded, and wherein the folding turret (31) is preceded by a group turret (28) which conveys the cigarette groups (21) into the group pockets (64), the articles being pushed into a pocket (64) in the direction of the longitudinal axis of the cigarettes and parallel to the rotational axis of the group turret (28), and being pushed out in an axially transverse direction, the improvement comprising the steps of:
- conveying cigarette groups (21) in group pairs (21a, 21b) in two tracks located next to one another;
- providing the pockets (64) with an axial length which is greater than twice the longitudinal length of the cigarettes;
- and, in the region of a pushing-in station (27), pushing two cigarette groups (21a, 21b) in succession into a common pocket (64) in such a way that the cigarette groups (21a, 21b) are arranged inside the pocket (64) at a distance from one another in the axial direction, wherein a first cigarette group (21a), distant from an inlet side pushing-in orifice (68) of the pocket, is pushed into the pocket (64) in a first pushing-in stroke, and the second cigarette group (21b) adjacent the pushing-in orifice (68) is pushed into the pocket (64) in a second pushing-in stroke.
Apparatus for packaging cigarettes combined into cigarette groups, by wrapping them in at least one blank of packaging material, and including a folding turret, a group turret, a pushing-in station, a pushing-out station and mans for conveying and introducing a cigarette group into a pack pocket of the folding turret, taking with it the blank provided in a plane transverse relative to the conveying direction, and during its further movement the blank being folded, said apparatus comprising means for combining the cigarettes (25) into individual cigarette groups (21) in group pockets (64) in the region of the group turret (28) preceding the folding turret (31) in the conveying direction, means for pushing the cigarettes (25), in the region of the pushing-in station (27), into several pockets (64) simultaneously in the longitudinal axis direction of the cigarettes and, means, in the region of the pushing-out station (29), for pushing cigarette groups out of one of the pockets in the axially transverse direction, the pockets having, in a direction parallel to the rotational axis of the group turret (28), an axial length greater than twice the longitudinal length of a cigarette group so that each pocket can receive in the axial direction two cigarette groups (21a, 21b) located next to one another;
- and means for, during each pushing-in stroke, pushing two cigarette groups (21a), to be distant from a pushing-in orifice (68) of the pockets (64), into two first pockets (64a, 64b) located at the rear in the conveying direction, and pushing two different cigarette groups (21b), to be adjacent the pushing-in orifice (68), into two different pockets (64c, 64d) located at the front in the conveying direction.
