  • Publication number: 20070042885
    Abstract: The invention relates to a packaging machine. There are packaging machines known that form a planar material in order to produce a package. Thereby, the planar material is formed, i.e. folded, wrapped, deep-drawn or the like. The planar material is commonly provided as a plastic film, especially with a plurality of layers of different materials. To produce a package, the planar material is scored along a score line such that for example easy open features are applied to the packaging. Conventionally, large quantities of the unscored planar material is stored on rolls. According to the state of the art, in a first step, the material to score is unrolled, then scored, and finally rolled up again on a roll. This procedure can not easily be adapted to the production of different kind or forms of packages.
