Abstract

L'invention concerne un dispositif de formation d'une pluralité de bandes (12a-b) de sacs (14a-b), tels que des sacs scellés sur 3 côtés, en particulier des stickpack, ou des sacs scellés sur 4 côtés, en particulier des sachets, à partir d'au moins une bande de matériau (16a-b), comprenant une pluralité de modules fonctionnels (20a-b) montés dans une direction de bande (18a-b) le long de chacune des bandes (12a-b), lesquels modules fonctionnels sont destinés à effectuer respectivement au moins une opération pour former les sacs (14a-b). L'invention comporte une unité de support (22a-b) qui est destinée à supporter au moins une partie des modules fonctionnels (20a-b) le long de la direction de bande (18a-b) et/ou dans une direction de rangée (26a-b) transversale à la direction de bande (18a-b) à des distances (24a-b) réglables les unes par rapport aux autres.
