Title: PRODUCTION OF PACKAGES MADE OF FLEXIBLE MATERIAL AND COMPRISING ONE OR MORE ROUNDED CORNERS AND ONE OR MORE EASY-OPENING INDENTATIONS
Abstract:
A cutting element (400) for a machine for producing packages (100') of flexible material is described, comprising at least one rounded corner (1061,106r) and an indentation for facilitated opening (1031,103r), the cutting element (400) comprising a main body (401) from which a single projecting element (402) projects, wherein the projecting element (402) projects from the main body (401) at a base area (403) of the projecting element (402), the base area (403) comprising a first arched area (404) and wherein the projecting element (402) also comprises an end (406) arranged in the end area of the projecting element (402) and configured so as to form the indentation for facilitated opening (103l, 103r) so that the cutter is adapted for forming a continuous cutting line (t1) that defines at least one first rounded corner (106r,106ra) and an indentation for facilitated opening (103l,103r) of a package (100'). A machine and a method for producing packages are also described.
