    • Device for fastening a flexible printing plate on a plate cylinder of a rotary printing press includes a tensioning bar disposed axially parallel with the plate cylinder in a cylinder gap formed in the plate cylinder, a clamping bar swivellably fastened to the tensioning bar, a cam shaft supported in respective end walls of the plate cylinder, a first and a second cam pair carried by the cam shaft, first and second spring assemblies, respectively, cooperating with the first and the second cam pairs, the cam shaft being rotatable in one direction for actuating the first cam pair to shift the tensioning bar via cam rollers and against a force of the first spring assemblies into a printing-plate take-up position, and for actuating the second cam pair to open the clamping bar via pins attached thereto against a force of the second spring assemblies so that a trailing end of the printing plate is insertable into the open clamping bar, the cam shaft being rotatable in a direction opposite to the one direction for initially actuating the second spring assemblies to close the clamping bar and for then actuating the first spring assemblies to shift the tensioning bar into a printing-plate tensioning position.
    • 用于将柔性印版紧固在旋转印刷机的印版滚筒上的装置包括:张紧杆,其设置成与印版滚筒轴向平行地形成在印版滚筒中的气缸间隙中,夹紧杆可转动地固定到张紧杆上,凸轮轴 支撑在印版滚筒的相应的端壁中,由凸轮轴承载的第一和第二凸轮对,分别与第一和第二凸轮对配合的第一和第二弹簧组件,凸轮轴可沿一个方向旋转, 致动第一凸轮对以经由凸轮辊移动张紧杆,并抵抗第一弹簧组件的力到印刷板卷绕位置,并且用于致动第二凸轮对以通过连接到其上的销通过夹紧杆打开夹紧杆 第二弹簧组件的力,使得印版的后端可插入打开的夹紧杆中,凸轮轴可沿与 用于初始致动第二弹簧组件以关闭夹紧杆并且然后致动第一弹簧组件以使张紧杆移动到印刷板张紧位置的一个方向。
