Abstract
An arrangement for scoring continuously transported flat workpieces to be folded along scored lines is composed of scoring tools fastened to shafts that are parallel to each other. One part of the scoring tools features a groove and the other part features a ridge. The groove and the ridge follow a helical path over external cylinders defined by the tools and engage with each other in the contact region of their cover lines. In order to set lengths of the scored lines, a tool part is composed of a package of tightly compact, discoid segments that carry the scoring tools. At least one part of these segments can be retained on the shaft in a manner permitting rotation, and located at different angles, in order to be able to form two scored lines with only one pair of scoring rolls. A cylindrical saucer-type segment forming a second scoring tool is retained on each shaft. One of the cylindrical saucer-type segments is provided with a helical ridge and the other cylindrical saucer-type segment is provided with a helical groove. The helical ridge and the helical groove engage with each other in the contact region of their cover lines of the external cylinder defined by the same.
