Abstract (en)
The method involves separating blanks (24-27) from a material web by successively attached partial sections (40, 41), where the material web is moved in a web direction. A recess, a set of notches (42-45) and a set of tearing notches (46-49) are located at areas at which the partial sections meet one another. The recess and the notches exhibit rounded contours. One of the partial sections is bent, where the partial section and one of the corresponding notches or the recess is simultaneously used. An independent claim is also included for a tool for producing a blank, comprising a blade.
Abstract (de)
Bei der Herstellung von Zuschnitten (3, 4) aus bahnförmigem Material (1) werden im Material nacheinander Teilschnitte (5, 6) angebracht. Um unvermeidliche Toleranzen der gegenseitigen Lage der Teilschnitte auszugleichen, sind an den Stellen, an denen sich die Teilschnitte treffen Ausnehmungen (9, 10) angeordnet.
