Abstract (en)
[origin: EP2743072A1] The method involves arranging multiple creasing tools (3-6) having tool pairs on the respective shafts (20,21,30,31) in a working position. Each tool is formed of an elevation and a recess which are arranged mirror-symmetrical relative to an imaginary center plane of the tool pairs. One of the tool pairs engaged with the shafts in a meshing state, is shifted from the working position to the new working positions, for introducing two spaced grooves (61,62) in a conveying direction of a creasing device (1). Independent claims are included for the following: (1) a creasing apparatus for introducing two spaced grooves in sheets of a printing material; and (2) a print processing apparatus.
