    • 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。

    • A method and apparatus for splitting wood slabs substantially along the wood grain into longitudinal-grain wood strands are provided. The apparatus comprises a rotating disc splitter having a pair of parallel rotary shafts each having centered thereon and secured thereto a series of spaced apart circular discs, means for counter rotating the shafts to pull a slab of wood between the series of discs and to split the slab into strands, and a series of floating spacer rings on each shaft interspaced between the discs, the floating spacer rings being positioned on either side of the shafts adapted to permit the spacer rings to move away from the discs when a slab is being split therebetween. The method comprises inserting an end of a slab of wood between counter rotating discs, a first series of discs pushing first sections of the slab in one direction perpendicular to the direction of travel of the slab and perpendicular to the axes of the counter rotating discs, a second series of discs interfitting with the first series of discs pushing second sections of the slab between the first sections in an opposite direction to the one direction thus causing splitting to occur between first sections and second sections of the slab and forming strands, and guiding the first sections and second sections of the slab downstream of the counter rotating discs to issue as substantially straight strands from the counter rotating discs.
    • 提供了一种用于将木材基本上沿着木纹分割成纵纹木线的方法和装置。 该装置包括具有一对平行旋转轴的旋转盘分离器,每个平行的旋转轴各自具有中心并固定在其上的一系列间隔开的圆盘,用于反转旋转轴以在一系列盘之间拉动木板并将 并且在每个轴之间的一系列浮动间隔环间隔在盘之间,浮动间隔环位于轴的任一侧上,适于当板在其间分开时允许间隔环远离盘移动 。 该方法包括将木板的一端插入反向旋转盘之间,第一系列盘沿垂直于板坯行进方向的一个方向推动板坯的第一部分并垂直于反转盘的轴线, 与第一系列光盘相互配合的第二系列光盘将第一部分之间的板坯的第二部分沿与一个方向相反的方向推动,从而在板坯的第一部分和第二部分之间产生分裂并形成绞线,并且引导 反向旋转盘下游的板坯的第一部分和第二部分从反向旋转盘发出为基本上直的股线。
