Abstract
For the wrapping of articles, especially cigarette packs (10) in an outer wrapping (11) consisting of film material or the like, a high output is required. The cigarette packs (10) come from the preceding packaging machine in a close-packed row (42). Two cigarette packs (10) at a time are pushed upwards out of the close-packed row (42) into pockets (30, 31) of a folding turret (29). During the pushing-in movement, a blank (12, 13) is laid round the respective cigarette packs (10) in a U-shaped manner. The two blanks (12, 13) are separated from a common web of material (47) and fed to the cigarette packs (10) via conveying rollers in an exact position transverse relative to the pushing direction.

In a process for wrapping packs (10) in blanks (12, 13) which are first laid around the packs in a U-shaped manner and whose projecting tabs (16, 17, 20-23) are then folded, in which process two packs (10) are simultaneously pushed into pockets (30, 31) of a folding turret (29) by a pusher, a blank (12, 13) at the same time being taken up in a U-shaped manner, the blanks (12, 13) being separated from a common web of material (47) and being conveyed in the correct position into the path of movement of the packs (10) in front of the pusher, the improvement comprising the steps of:
- deforming the blanks (12, 13), or the web portion for forming the blanks, in front of the pusher in the region of said path of movement of the packs (10), in a wave-shaped manner, to reduce the necessary distance between the packs (10) to be wrapped simultaneously;
- conveying the blanks into the path of movement of the packs (10);
- pushing out the packs (10), to be pushed simultaneously into pockets (30, 31) of the folding turret (29), from a close-packed row (42) of packs (10) in a transverse direction relative to the packs and
- pushing the packs into the pockets (30, 31).
In an apparatus for wrapping packs (10) into blanks (12, 13) and which comprises:
- a pusher for the pushing of packs (10) into pockets (30, 31) of a folding turret and during which pushing the blanks are folded around the packs (10) in a U-shaped manner and are ready-folded in the region of the folding turret;
- conveying members, in the form of rotatable conveying rollers (48-50), for conveying a region of web of material (47), corresponding to a corresponding number of blanks (12, 13), to the packs (10) for simultaneous wrapping of two packs (10);
- and a separating member for severing the blanks from the web of material (47), the improvement comprising guiding means for guiding the web (47) or blanks (12, 13) in a conveying path which runs around several conveying rollers in a wave-shaped manner in front of the pusher and the path of movement of the packs (10) to be wrapped.
