Abstract
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.
Claims16
A unit for packaging products in respective flat diecut blanks generating packs of substantially parallelepiped appearance, wherein at least one edge portion of the blank is folded in such a way as to establish a respective face of the pack, comprising:
- means by which to fold the edge portion as the products advance along a predetermined folding path in a predetermined direction, runner means forming part of the folding means capable of movement in a direction concurrent with that of the advancing products and disposed in contact with the edge portion of the blank during the course of the folding step, the folding means including respective means for guiding the runner means, the guide means associated with the runner means at opposite sides of the edge portion of the blank.
A unit for packaging products in respective flat diecut blanks generating packs of substantially parallelepiped appearance, wherein at least one edge portion of the blank is folded in such a way as to establish a respective face of the pack, comprising:
- means by which to fold the edge portion as the products advance along a predetermined folding path in a predetermined direction, runner means forming part of the folding means capable of movement in a direction concurrent with that of the advancing products and disposed in contact with the edge portion of the blank during the course of the folding step, wherein the runner means comprise a plurality of needle rollers generating a relative folding surface that winds helically at least in part, and designed to enter into contact with the edge portions.
