Unit for packaging products

摘要

In a unit by which groups of cigarettes are packed in rigid type packets, the single packet is fashioned from a flat diecut blank folded around the group. An assembly consisting of one blank and one group is directed along a predetermined path and conveyed ultimately into a folding station with the blank still presenting two lateral flaps to be bent over and flattened; the station comprises two folders each presenting a fixed shoe of helical geometry around which a belt is looped slidably and positioned to engage a respective lateral flap as the assembly advances along the relative folding path, the active branch of the loop running in a direction concurrent with that of the advancing assemblies.
