    • The printing press includes a printing cylinder and an inking roll operatively positioned on a frame means and characterized by positioning arms engaging the inking roll for pivotal movement of such roll towards and away from the printing cylinder to operative and inoperative positions, respectively. Fluid actuating means operatively engages the positioning arms for moving the inking roll and an adjustment device is present to control the extent of movement of said inking roll. Further adjustment means are provided in the positioning arm engaging one end of the inking roll to aid in operatively positioning the inking roll parallel to the printing cylinder.
    • 印刷机包括可操作地定位在框架装置上的印刷滚筒和着墨辊,其特征在于定位与所述着墨辊接合的臂,用于将所述辊朝着印刷滚筒和远离印刷滚筒的枢转运动转动到操作和非操作位置。 流体致动装置可操作地接合定位臂以移动着墨辊,并且存在调节装置以控制所述着墨辊的移动程度。 在定位臂中设置有进一步的调节装置,该定位臂与着墨辊的一端接合,以帮助将着墨辊平行于印刷滚筒操作地定位。
