Method for producing an elongated protective layer for the shape-forming material of a blank

Abstract

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.

1 . A method of production of a package workpiece in which a protective layer is applied to the frame roll or sheet material to obtain a forming material, which is distinguished by the fact that a protective layer is applied outside the frame roll or sheet material on one side or both sides to form a loose edge, not attached to the frame material, carry out die-cutting or cutting of multilayer material along the contour of the workpiece, in places of obtaining an elongated protective layer die-cutting or cutting is carried out directly at the freely lying edge, taking into account the allowance for elongation of the protective layer of the workpiece.
