Method for wrapping a plurality of articles

A method for wrapping a plurality of articles, comprising steps of:

• forming a closed-loop structure, either by attaching on a first face of a length of flexible material a face of at least one flat and rigid element and by attaching an opposite face of said flat and rigid element, to a second face of an end portion of the length of flexible material, so as said closed-loop structure is a closed-loop cover carrying the flat and rigid element,
• or by attaching both ends of a length of flexible material to respective parts of a support, so as said closed-loop structure is formed by a sequential assembly of said length of flexible material and said support, wherein at least one flat and rigid element is optionally attached on a first face of said length of flexible material,
• enclosing said plurality of articles within the closed-loop structure,
• folding the closed-loop structure either along the at least one flat and rigid element attached on the first face of the length of flexible material, if the at least one flat and rigid element is present, or along at least one of the parts of the support to which said ends of the length of flexible material are attached, and
• attaching a folded portion of the closed-loop structure to an adjacent surface of the closed-loop structure, so as said closed-loop structure tightly wraps said plurality of articles.
