  • a convex part not shown which increases pressing force F against the side wall 30e while the box 30 is conveyed in the conveyance path 26 may be formed in at least one of the pair of pressing wall surfaces 28d.
  • each embodiment has been described on the assumption that the box 30 is a cigarette package SP which provides a hinge-lid round corner box.
  • the present invention can be applied to shaping of a square box having no round corner 36, cigarette packages SP other than the form of hinge-lid, and boxes 30 for uses other than cigarette package SP.
  • the box 30 when the box 30 is a round corner box, since it has folding lines 46 for forming the round corner 36, pre-folding of the inner and outer side flaps 40e, 40f is performed with less intensity compared with a case of a square box. For this reason, the restoring force against pre-folding of the inner and outer side flaps 40e, 40f tends to increase in the case of a round corner box compared with a square box. Therefore, when the box 30 is a round corner box, due to the concerned restoring force, bonding defects and, by extension, defective shaping of the box 30 is more likely to occur than in the case of a square box.
  • the packaging machine 1 can assume various forms without being limited to the above described configurations, provided that it includes a conveyor 28 having the above described means.
  • a heater not shown may be provided in the conveyance path 26 to promote bonding of the box 30 through drying.

    le trajet de transport (26) présente une paire de parois de transport (28a) pour maintenir entre elles la boîte (30) par la paire de parois latérales (30e), et inclut un transporteur (28) pour transporter la boîte (30) tout en la maintenant entre les parois de transport (28a) ;
    la paire de parois de transport (28a) incluent respectivement des surfaces de paroi de pression (28d) pour presser sensiblement une région d'application de colle (48 ; 50) des parois latérales (30e) ; et
    au moins l'une des surfaces de paroi de pression (28d) inclut un moyen (56 ; 58 ; 60) pour réduire une longueur efficace totale de la surface de paroi de pression (28d) le long de l'axe longitudinal (32) pour qu'elle soit inférieure à une longueur totale de la paroi latérale (30e) de la boîte (30) ; dans laquelle
    la boîte (30) prend une forme cuboïde, et inclut en outre une paroi avant (30a), une paroi arrière (30b), une paroi supérieure (30c), et une paroi inférieure (30d), et
    le moyen (56 ; 58; 60) est formé dans une portion de la surface de paroi de pression (28d) faisant face à au moins une partie d'extrémité de la paroi latérale (30e) de la boîte (30).
  2. Machine d'emballage (1) selon la revendication 1, dans laquelle
    la surface de paroi de pression (28d) présente une partie entaillée (56) qui n'est pas en contact avec la partie d'extrémité de la paroi latérale (30e) pendant que la boîte (30) est transportée dans le trajet de transport (26), et
    la partie entaillée (56) constitue le moyen (56 ; 58 ; 60).
  3. Machine d'emballage (1) selon la revendication 1 ou 2, dans laquelle
    la surface de paroi de pression (28d) présente une largeur (W) s'étendant dans une direction traversant le trajet de transport (26), et la largeur (W) est plus courte qu'une longueur totale de la paroi latérale (30e) pour réaliser le moyen (56 ; 58 ; 60).
  4. Machine d'emballage (1) selon l'une quelconque des revendications 1 à 3, dans laquelle
    la surface de paroi de pression (28d) présente une partie concave (58) qui n'est pas en contact avec la paroi latérale (30e) pendant que la boîte (30) est transportée dans le trajet de transport (26), et
    la partie concave (58) constitue le moyen (56 ; 58 ; 60).
  5. Machine d'emballage (1) selon l'une quelconque des revendications 1 à 4, dans laquelle
    le moyen (56 ; 58 ; 60) est formé en tant qu'une partie incurvée (60) dans la portion de la surface de paroi de pression (28d), et
    la partie incurvée (60) prend une forme arquée séparée de la paroi latérale (30e) pendant que la boîte (30) est transportée dans le trajet de transport (26).
  6. Machine d'emballage (1) selon l'une quelconque des revendications 1 à 5, dans laquelle
    le transporteur (28) comprend :
    une paire de courroies (28a) qui forment la paire de parois de transport (28a) ; et
    une pluralité de galets à couronne (62) qui guident les courroies (28a) le long du trajet de transport (26).
  7. Machine d'emballage (1) selon l'une quelconque des revendications 1 à 6, dans laquelle
    au moins l'une des surfaces de paroi de pression (28d) inclut une partie convexe qui augmente une force de pression (F) contre la paroi latérale (30e) pendant que la boîte (30) est transportée dans le trajet de transport (26).
