Title (EN) A METHOD AND AN APPARATUS FOR APPLYING A SEALING STRIP TO A WEB OF PACKAGING MATERIAL
(FR) PROCÉDÉ ET APPAREIL PERMETTANT D'APPLIQUER UNE BANDE DE SCELLEMENT SUR UNE BANDE DE MATÉRIAU D'EMBALLAGE
Abstract:
(EN) There is described a method of applying a sealing strip (11) onto a web (4) of packaging material within a strip application apparatus (10) comprising a conveying phase during which the web (4) is advanced along a web advancement path (P); an application phase during which a first longitudinal portion (27) of the sealing strip (11) is applied onto a longitudinal edge (19) of the web (4), a sealing phase during which the first longitudinal portion (27) of the sealing strip (11) is sealed onto the longitudinal edge (19), a control phase during which a correct alignment or a misalignment of the sealing strip (11) with respect to the web (4) is detected and/or determined. The control phase comprises at least an imaging sub-phase during which an image of at least a second longitudinal portion (31) of the sealing strip (11) and at least one reference marker (29) of the strip application apparatus (10) is acquired, a determination sub-phase during which the acquired image is analyzed to determine at least a first transversal distance (d1) between the reference marker (29) and a longitudinal border (57) of the second longitudinal portion (31); and an analysis sub-phase during which the correct alignment or the misalignment is evaluated as a function of at least the first transversal distance (d1).
(FR) La présente invention concerne un procédé d'application d'une bande de scellement (11) sur une bande (4) de matériau d'emballage à l'intérieur d'un appareil d'application de bande (10) comprenant une phase de transport au cours de laquelle la bande (4) est avancée le long d'un trajet d'avancement de bande (P), une phase d'application au cours de laquelle une première partie longitudinale (27) de la bande de scellement (11) est appliquée sur un bord longitudinal (19) de la bande (4), une phase de scellement au cours de laquelle la première partie longitudinale (27) de la bande de scellement (11) est scellée sur le bord longitudinal (19), une phase de commande au cours de laquelle un alignement correct ou un mauvais alignement de la bande de scellement (11) par rapport à la bande (4) est détecté et/ou déterminé. La phase de commande comprend au moins une sous-phase d'imagerie au cours de laquelle une image d'au moins une seconde partie longitudinale (31) de la bande de scellement (11) et d'au moins un marqueur de référence (29) de l'appareil d'application de bande (10) est acquise, une sous-phase de détermination pendant laquelle l'image acquise est analysée pour déterminer au moins une première distance transversale (d1) entre le marqueur de référence (29) et une bordure longitudinale (57) de la seconde partie longitudinale (31) ; et une sous-phase d'analyse au cours de laquelle l'alignement correct ou le désalignement est évalué en fonction d'au moins la première distance transversale (d1).
