Abstract: The invention relates to a blank (1), a method and a machine (11) for realising the blank (1). The blank (1) is constituted by four lengths (5) which are consecutively joined to form a structure (2) or frame (6) which can be folded around one or more flat articles (4) or tiles to be packed. The machine (11) and the method for realising the blanks (1) include supplying identical panels of cardboard which are joined to constitute a continuous strip (10) and which are subsequently cut to correspond to lengths of sides of the tiles. Each length (5) is joined to a consecutive length (5) by deposits (7a) of glue.
