    • The invention pertains to a device (1) for the rotative scoring of flat printed products in order to prepare a bending line, particularly in a brochure cover that is supplied in the form of a sheet (2), with said device featuring at least one pair of scoring tools (11.1, 11.2) that consists of a scoring knife (12) and an assigned scoring matrix (13), with the scoring tools (12, 13) being arranged on a first and a second scoring shaft (14.1, 14.2) that are arranged parallel to one another and driven in opposite directions, and with said device also featuring at least one pair of transport rollers (30) that is arranged axially adjacent to the pair of scoring tools (11.1, 11.2) and consists of a first and a second transport roller (31, 32) that effectively clamp the sheet (2) between one another with respect to its transport, wherein it is proposed that the first transport roller (31) is arranged on the first scoring shaft (14.1) and the second transport roller (32) is supported independently of the scoring tools (12, 13). The axial spacing of the at least one pair of scoring tools (11.1, 11.2) can be adjusted in accordance with the desired scoring depth without affecting the at least one pair of transport rollers (30). The load on the scoring shafts (14.1, 14.2) is significantly reduced because bending due to an excessively narrow adjustment of the transport rollers (31, 32) is prevented.
    • 本发明涉及用于平面印刷产品的旋转刻痕的装置(1),以便制备弯曲线,特别是在以片材(2)的形式供应的小册子盖中,所述装置具有至少一个 由刻痕刀(12)和分配的刻痕矩阵(13)组成的一对刻痕工具(11.1,11.2),其中所述刻痕工具(12,13)布置在第一和第二刻划轴(14.1,14.2 ),它们彼此平行布置并且沿相反方向被驱动,并且所述装置还具有至少一对传送辊(30),所述至少一对传送辊(30)轴向地邻近所述一对刻痕工具(11.1,11.2)布置,并且由 第一和第二输送辊(31,32),其相对于其输送物有效地夹住纸张(2),其中提出第一输送辊(31)布置在第一刻划轴(14.1)上, 并且第二输送辊(32)被独立地支撑 得分工具(12,13)。 至少一对打分工具(11.1,11.2)的轴向间距可以根据所需的打分深度进行调节,而不影响至少一对输送辊(30)。 由于防止由于输送辊(31,32)的调节过小而导致的弯曲,所以刻划轴(14.1,14.2)上的载荷显着降低。
