Abstract
A method for wrapping a cardboard box with a wrapping sheet, includes: providing a cardboard box with a continuous edge delimiting an opening of the box; providing a wrapping sheet; coupling the box and the sheet; placing on a supporting surface the box coupled to the sheet so that the opening of the box is opposed to the supporting surface; positioning a closing system on the continuous edge of the box so as to define a closed chamber that is comprised between the box and the closing system; supplying air inside the closed chamber so as to make the box adhere to the sheet.

Method for wrapping a box with a wrapping sheet, the method comprising:
- providing a cardboard box (100) having a base (101), lateral walls (102) connected to said base (101) and a continuous edge (103) which is defined by said lateral walls (102) and delimits an opening (104) of said box (100);
- providing a wrapping sheet (200) having a main portion (201) with an internal surface (211) and an external surface (221) opposed to each other;
- joining said internal surface (211) of said main portion (201) to said base (101) of said box (100), to couple said box (100) to said sheet (200);
- placing said box (100) coupled to said sheet (200) on a supporting surface (11) so that said opening (104) of said box (100) is opposed to said supporting surface (11);
- positioning a closing system (20) on said continuous edge (103) to define a closed chamber that is comprised between said box (100) and said closing system (20);
- supplying a gaseous material inside said closed chamber so that said base (101) of said box (100) adheres to said main portion (201) of said sheet (200).
Apparatus for wrapping a cardboard box (100) with a wrapping sheet (200), the apparatus comprising:
- a main frame (10) having a supporting surface (11) configured to support said box (100) coupled to said sheet (200) at a base (101) of said box (100);
- at least one closing system (20), arranged to face said supporting surface (11), movable relative to said supporting surface (11) and configured for positioning on a continuous edge (103) of said box (100) delimiting an opening (104) opposed to said supporting surface (11), in order to define a closed chamber comprised between said box (100) and said closing system (20);
- a pneumatic blower (40), connected to said closing system (20) and configured to supply a gaseous material inside said closed chamber.
