Description

  The present invention relates to a packaging method and a packaging machine for manufacturing a packet including a group of different kinds of articles.

  In the following description, for the sake of simplicity, cigarette (cigarette) hinged lid packets will be described, which are merely non-limiting examples.

  A group of fewer than 20 cigarettes instead of the usual group of 20 cigarettes (in a 3 row) to commemorate special events (such as the launch of a new cigarette brand or a commemorative celebration) And special cigarette packets have been proposed that include one or more promotional items. For example, one format includes a group of 13 cigarettes (in two rows) and a lighter (with brand name) (ie a lighter with the cigarette trademark), and other formats , A group of 5 cigarettes (in a row), a lighter (with brand name), and a metal cigarette case (with brand name).

  However, this type of special cigarette packet is manufactured by a standard packaging machine that is not designed to handle groups of dissimilar items (ie cigarette groups and lighters, or cigarette groups, lighters, and cigarette cases). It is impossible to do and requires a special packaging machine that is significantly different from the standard format and is therefore very expensive to manufacture and maintain.

  Patent Document 1 describes a cigarette packaging machine. In the embodiment of FIG. 4 of this patent document, each sheet of the wrapping wheel receives a cigarette envelope group at a first station and is equivalent in size to the cigarette envelope group at a second feeding station. It is adapted to receive either other cigarette envelopes or other items having a thickness. The group of either two cigarette envelopes or one envelope group of cigarettes and another item is then transferred to the subsequent wrapping wheel where the blanks are folded around the group. Thus, an outer package is formed.
