Problems solved by technology

However, flexible wrappers cannot be weakened along the final edges of the flexible wrapper prior to folding, because the flexible wrapper, once weakened, is no longer convenient for handling on a packaging machine, and because the wrapper cannot be determined with sufficient accuracy in advance. The exact position of the edge of the

Embodiment Construction

[0025] Figure 1-Figure 3 Reference numeral 1 in generally indicates a soft pack defined by a substantially parallelepiped-shaped soft pack of cigarettes having a rectangular cross-section.

[0026] A cigarette pack 1 comprises: a parallelepiped-shaped inner wrapper 2 containing groups of cigarettes 3 wrapped in a soft (i.e. non-rigid) foil inner wrapper 4; and a cup-shaped outer wrapper 5, which The package includes a soft (ie, non-rigid) outer wrapper 6 wrapped around the inner package 2 to cover the five walls of the inner package 2 (ie, leaving the top wall of the inner package 2 exposed).

[0027] The outer packaging 5 is cup-shaped (i.e. open at the top), is in the form of a rectangular parallelepiped, and comprises a bottom wall 7 and four side walls 8 which are divided into two larger side wall 8 and two smaller side walls 8 . Four longitudinal edges 9 are defined between the side walls 8, that is, each longitudinal edge 9 defines a boundary between two adjacent side...

Abstract

The present invention discloses a method and unit of processing the edges (9) of a soft package (5), the method including the steps of folding a soft wrapping (6) about an article (3) to form the soft package (5) having a number of edges (9), each defining the boundary between two adjacent walls (8) of the soft package (5); and, once the soft wrapping (6) is folded about the article (3), subjecting the soft package (5) to a shaping process to shape the soft wrapping (6) along at least one edge (9) to obtain a sharp edge (9) and to square the soft wrapping (6) along the edge (9).

Description

technical field [0001] The invention relates to a method and a unit for processing the edges of flexible packaging. [0002] In the following description, for the sake of simplicity and by way of non-limiting example only, soft packs of cigarettes are referred to. Background technique [0003] Flexible packs of cigarettes comprising: a parallelepiped-shaped inner pack comprising a group of cigarettes wrapped in a flexible (i.e. non-rigid) inner wrapper or foil; and an outer pack comprising a A soft (ie, non-rigid) outer wrapper that wraps around the inner package to cover the five walls of the inner package (ie, leaving the top wall of the inner package exposed). [0004] Along the longitudinal edges, the inner wrapper wraps around the end cigarettes of the group of cigarettes and thus tends to be rounded (ie curved, thereby forming rounded edges). Consequently, when the outer wrapper is wrapped and folded around the inner package, it is not possible to obtain a sharp, cle...
