Abstract

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.
