Abstract:
A packaging machine (1) includes a conveyance path (26) for forming a box (30) by folding a blank around the periphery of a plurality of smoking articles, and for conveying the box (30) to a subsequent processing stage. The box (30) includes a longitudinal axis line (32) and a pair of lateral walls (30e) extending along the longitudinal axis line (32) and having inner and outer lateral wall parts (34a and 34b) bonded to each other. In the conveyance path (26), the pair of lateral walls (30e) are positioned to extend in a direction crossing the conveyance path (26). The conveyance path (26) is provided with a conveyor (28) including a pair of conveyance walls (28a) between which the box (30) is held at the pair of lateral walls (30e), the conveyor (28) conveying the box (30) being held between the conveyance walls (28a). The pair of conveyance walls (28a) include respective pressing wall surfaces (28d) that substantially press the lateral walls (30e). At least one of the pressing wall surfaces (28d) has means (56, 58, 60) for making a total effective length (L) of the pressing wall surfaces (28d) along the longitudinal axis line (32) smaller than an entire length (La) of the lateral walls (30e).
