    • There is provided a rotary die cutter for effecting a punching and scribing on a sheet which is fed between a die cylinder and an anvil cylinder disposed in parallel with said die cylinder. The die cylinder is adapted to be rotated in a predetermined direction and provided on its peripheral surface with a knife and a scribing rule. The anvil cylinder is adapted to be rotated in the opposite direction to the die cylinder and provided on its peripheral surface with an anvil for receiving the knife and the scribing rule. There is a mechanism for adjusting the clearance between the die cylinder and the anvil cylinder. A blade carrier is disposed adjacent to the anvil cylinder and slidable in the axial direction of the anvil cylinder. A cutting blade capable of cutting the anvil surface is attached to the blade carrier in such a manner as to move toward and away from the axis of the anvil cylinder. A staged gear type speed changing device is interposed between the driving mechanisms for the die cylinder and the anvil cylinder for and is adapted to change the velocity of the anvil cylinder with respect to that of the die cylinder over a plurality of stages at a fine step.
    • 提供了一种旋转模切机,用于在被供给在与所述模具缸平行设置的模具缸和砧座缸之间的片材上进行冲压和划线。 模具圆筒适于沿预定方向旋转,并且在其外周表面上用刀和划线规则设置。 砧筒适于沿着与模具缸相反的方向旋转并且在其外周表面上设置有用于接收刀的砧座和划线规则。 存在用于调节模具缸和砧筒之间的间隙的机构。 叶片载体邻近砧筒设置并可在砧筒的轴向上滑动。 能够切割砧座表面的切割刀片以使得朝向和远离砧座圆柱体的轴线移动的方式附接到刀片托架。 分级齿轮式变速装置设置在用于模具缸和砧座缸的驱动机构之间,并且适于在多个阶段以精细步骤改变砧筒相对于模具缸的速度 。

    • Flexographic printing press for printing on the corrugated board sheets passing between the printing cylinder provided with a form plate on its peripheral surface and the receiving roll. Flexographic ink stored between a doctor roll and an anilox roll, which are rotated in the opposite directions as these rolls contact each other, is supplied to said form plate via said anilox roll to thereby carry out a printing operation. Said anilox roll is driven by said printing cylinder at same peripheral speed. Said doctor roll is driven by a speed change drive mechanism for reducing the peripheral speed of said doctor roll when the rotational speed of said anilox roll is increased, and increasing the peripheral speed of said doctor roll when the rotational speed of said anilox roll is decreased. The preferred speed change drive mechanism consists of a differential gear means having an output shaft connected to said doctor roll, a motor for driving said differential gear means and means for transmitting the force of rotation of said anilox roll to said differential gear means.
    • 柔性版印刷机,用于印刷在波纹板上,在其外周表面上设置有成形板的印刷滚筒和接收辊之间。 存储在刮辊和网纹辊之间的柔性油墨通过所述网纹辊被供给到所述成形板,从而进行打印操作。 所述网纹辊以相同的圆周速度由所述印刷滚筒驱动。 所述刮刀辊由变速驱动机构驱动,当所述网纹辊的旋转速度增加时,用于降低所述刮刀辊的圆周速度,并且当所述网纹辊的旋转速度减小时提高所述刮刀辊的圆周速度 。 优选的变速驱动机构包括具有连接到所述刮刀辊的输出轴的差速齿轮装置,用于驱动所述差速齿轮装置的马达和用于将所述网纹辊的旋转力传递到所述差动齿轮装置的装置。
