    • Apparatus for cyclically printing information on a moving web utilizes a stationary printing head at a printing station along the path traversed by the moving web and a roller which guides the web and sweeps the web across the printing head in the direction opposite to web advancement so that there is substantially no relative movement between the web and head as printing occurs. The roller is supported for sweeping movement back and forth over the printing head by means of a pivotal linkage driven by a crank which causes the guided web to engage the head during a sweep in one direction only. A cyclic drive for the linkage includes an eccentric gear set to modulate the speeds of the roller and web.
    • 用于在移动幅材上循环打印信息的装置利用沿着由移动幅材穿过的路径的印刷站处的固定打印头和引导纸幅的辊,并且在与纸幅前进方向相反的方向上将纸幅扫过打印头,使得 当印刷发生时,在幅材和头部之间基本上没有相对移动。 支撑辊通过由曲柄驱动的枢转联动器在打印头上前后移动,这使得被引导的纸幅仅在一个方向上的扫描期间啮合头部。 用于联动的循环驱动器包括偏心齿轮组,以调节辊和腹板的速度。

    • An ink transfer system for a rotary printing press wherein a helically grooved transfer roll is provided for effectively transferring toward a plate cylinder an ink volume consistent or equal to the usage requirements at any given point or area on the roll surface as determined by the printed image. The transfer roll has the ability to simultaneously transfer ink reversely back onto the fountain roll by reason of its helical grooves being in light contact with a relatively slowly rotating fountain roll. An offset groove and ball arrangement is provided for one of the distribution rolls in the printing press chain of rollers so as to smoothly oscillate the roll for a more even distribution of the ink transversely of each roll in the ink train. The inner face of each fountain roll mount is slightly relieved so as to direct ink away from the outermost ends of the fountain roll thereby substantially preventing fountain leakage.
    • 一种用于旋转印刷机的油墨传送系统,其中设置有螺旋槽的转印辊,用于有效地向印版滚筒传送与印刷图像确定的辊表面上任何给定点或区域上的使用要求一致或相等的墨水量 。 转印辊具有通过其相对缓慢旋转的喷墨辊轻轻接触的方式将油墨反向同时转印到喷墨辊上的能力。 为辊子的印刷机链中的一个分配辊设置偏移槽和球布置,以便平滑地摆动辊子,以便在油墨列中横向于每个卷轴的油墨均匀分布。 每个喷墨辊支架的内表面略微松开,以便将油墨从墨斗的最外端引导出来,从而基本上防止喷泉泄漏。
