    • To close the gaps (6) which result between the end or edge sections (7) of the gravure printing plates (2) when the latter are clamped on form cylinders (1) of rotary gravure presses, the gap (6) is covered with a cover element (8) in which at least that surface region which lies on the end or edge sections (7) of the gravure printing plate (2) and covers the gap (6) is deformable under pressure and can therefore be matched up with the surface contour in the gap region, the cover element is pressed onto the surface of the gravure printing plate, the resulting gap cavity is filled with a curable filling compound and, when curing of the filling compound is complete, the cover element is removed. It is particularly advantageous to use cover elements which are in the form of hollow bodies and which are filled with a pressure-generating and pressure-transmitting medium, and the pressure exerted on the deformable surface of the cover element which lies on the gravure printing plate, and hence also the surface contour of the closed gap, can be controlled via the internal pressure in the cavity of the cover element.
    • 为了封闭在凹版印刷版(2)的端部或边缘部分(7)之间产生的间隙(6),当缝隙(6)夹在旋转凹版印刷机的成型滚筒(1)上时,间隙(6)被覆盖 覆盖元件(8),其中至少位于凹版印刷版(2)的端部或边缘部分(7)上并覆盖间隙(6)的表面区域在压力下可变形,因此可与 间隙区域中的表面轮廓,盖元件被压在凹版印刷版的表面上,所得到的间隙空腔填充有可固化的填充化合物,并且当填充化合物的固化完成时,除去盖元件。 特别有利的是使用中空体形式的盖元件,其中填充有压力产生和压力传递介质,并且施加在位于凹版印刷板上的盖元件的可变形表面上的压力 ,并且因此也可以通过盖元件的空腔中的内部压力来控制闭合间隙的表面轮廓。

    • Apparatus for clamping printing plates for rotary printing presses, having one or more clamping strips which are arranged so that they are laterally displaceable in a cylinder recess, which grip under an end region of the plate to be clamped and whose outer contour has a curvature corresponding to the cylinder curvature and is bordered by a pressure surface which engages a bent-over edge claw of the plate to be clamped, an insertable, resilient strip being inserted between the pressure surfaces of the clamping strips and a compression strip which is adjustable radially with respect to the cylinder circumference, wherein the clamping strip is adjustable in the clamping direction of the printing plates by means of two or more hydraulic cylinders which are supported at their rear and on the adjacent cylinder wall.
    • 用于夹紧用于旋转印刷机的印版的装置,具有一个或多个夹持条,其被布置成使得它们在气缸凹部中可横向移位,该夹紧条夹持在要夹紧的板的端部区域下方,并且其外轮廓具有对应的曲率 相对于圆筒曲率并且由与要夹紧的板的弯曲边缘爪接合的压力表面接合,可插入的弹性条插入夹紧条的压力表面和压缩条之间,压缩条可径向调节, 相对于圆筒圆周,其中夹持条可以通过两个或多个液压缸在其印刷版的夹紧方向上可调节,所述液压缸在其后部和相邻的气缸壁上被支撑。
