Abstract

La présente invention concerne un dispositif d'emballage par torsion qui emballe de manière fiable même une pluralité d'articles qui doivent être emballés, et les tord pour les fermer sans que les articles qui doivent être emballés, ne changent de position sur une feuille continue. Un dispositif d'emballage par torsion (1) comprend une unité de transport (3) qui transporte une feuille continue (S) vers le bas, et un mécanisme de torsion rotatif (4) qui saisit le milieu de la feuille continue et la tord. Le mécanisme de torsion rotatif (4) comprend : des éléments de torsion (43a, 43b) qui prennent en sandwich la feuille continue formée dans un tube entre ces derniers et rendent cette dernière plate ; une unité d'entraînement en rotation (6) qui fait tourner les éléments de torsion (43a, 43b) tandis que la feuille continue est prise en sandwich entre ces derniers ; un dispositif de coupe (91) qui coupe la feuille continue prise en sandwich entre les éléments de torsion (43a, 43b) ; et une unité de maintien d'emballage (7) qui maintient, sous les éléments de torsion (43a, 43b), la feuille continue (S) dans laquelle est enveloppé l'objet qui doit être emballé.
