Definitions

  • the score line in the region of the tear-open part, in which the core wall 3 has its arcuate course in the end section of the tear-open part 26, the score line most suitably has a polygonal course, as is illustrated in FIG. 2. This does not rule out that the transitions at the polygonal corners are each formed by sections with a very small radius of curvature.
