Abstract (en)
The present invention is a method for producing an elongated protective layer for the shape-forming material of a blank, in which a protective layer is applied onto a web fed base material or sheet base material. The protective layer is applied beyond the edges of the web fed base material or sheet base material on one side or two sides in order to form a free edge that is not fastened to the base material. The multi-layer material is then cut or punched along the outline of a blank. In the places where an elongated protective layer is produced, the cutting or punching is done directly along the free edge, taking into account a margin for the elongated portion of the protective layer of the blank. The invention protects the end faces of a material for a shapeable container.
