METHOD FOR PRODUCING A SHAPED SHEET OF WRAPPING

Described herein is a method for producing a shaped sheet of wrapping (10), including a hollow portion (10A) and a perimetral edge (10C) that extends along a pre-set profile (K), said method comprising the steps of:- laying a sheet of wrapping (100) on a treatment surface (50) having a forming cavit...

Zusammenfassung:	Described herein is a method for producing a shaped sheet of wrapping (10), including a hollow portion (10A) and a perimetral edge (10C) that extends along a pre-set profile (K), said method comprising the steps of:- laying a sheet of wrapping (100) on a treatment surface (50) having a forming cavity (50A);- forming said sheet of wrapping (100) within said forming cavity (50A) so as to reproduce the shape said hollow portion (10A) thereon, without subjecting said sheet of wrapping (100) to deformation by stretching;- cutting said formed sheet of wrapping (100) along said pre-set profile for producing said perimetral edge (10C) and obtaining said shaped sheet of wrapping (10).The method is characterised in that the cutting step envisages the use of a laser beam according to a particular cutting mode.
