Devices for turning sheets in a rotary printing machine are described.The devices have a storage drum for handing sheets,which are each held by a holding device,and a turning drum is disposed downstream of the storage drum and has a holding device for engaging a rear edge of the sheet to be turned.An operation of detaching the sheet to be turned from the storage drum and carrying it along by the turning drum leads to the formation of a pressure reduction in an area formed between the sheet to be turned,the storage drum and the turning drum.The pressure reduction is compensated for by supplying ambient air,blast air and/or compressed air.The turning device has a channel and/or a passage orifice connected to an inner chamber of the turning drum.Via the channel and passage orifice air can be sucked and blown into the reduced-pressure area
FIG.1 is a diagrammatic,side-elevational of an exemplary embodiment of a turning device for sheets according to the invention

The cylinder bearer rings are engaged with substantial engagement pressure.They are subject to substantial shock loading which occurs when the clamping grooves in the printing cylinders roll off against the associated cylinders.The bearer rings.Thus,have a limited life and have to be replaced from time to time.The bearer rings are usually located on the facing ends of the printing cylinders.Inside of the side walls of the printing press.To replace the bearer rings,it is thus necessary to disassemble the printing cylinder as well.Replacement of the bearer rings,thus,is very time-consuming and labor intensive.
To permit replacement of a cylinder bearer ring without disassembly of the respective cylinder from the printing machine,the cylinder bearer ring is constructed as a composite element assembled of two parts 1,9;one of the parts has a central,generally U-shaped cut-out to surround the shaft of the associated cylinder,the width of the cut-out being at least as large as the width of the cut-out being at least as large as the width of the diameter of the shaft; the other part,9,fits into the cut-out and is formed with a central part-circular recess to surround the shaft.The two parts 1,9
When interfitted,surround the shaft and form a continuous circular outline and thus a continuous bearer ring.The parts are secured together by bolts.Preferably,the engaging surfaces of the parts are formed with planes which are inclined with respect to a plane parallel to the facing side of the rings,so that,as the two parts run off against the associated bearer ring,there is no sudden transition of one part with respect to the other since the inclined surfaces will overlap axially.The cut-out is positioned at a circumferential region opposite that where the groove of the cylinder is located.

在转动印刷机械中,翻转板的设备是可以被描绘的.该设备为操作板设置了一个储存鼓,这个操作板的每一步操作都是通过控制装置实现的,一个翻转鼓沿着储存鼓顺序排列同时还有一个操作装置与薄板后边缘衔接,从而实现翻转.薄板与薄板之间的分离操作是为了实现翻转.
分离板的翻转操作可以通过储存鼓实现,同时通过翻转鼓向前运动,从而在储存鼓和翻转鼓的同一空间里实现压缩版的构成和薄板翻转.压缩版可以通过周围的空气、强气流或者压缩空气进行补偿.翻转装置的通道或者通路孔与翻转鼓的内腔相连.途径通道或者通路孔的空气可以被吸或是吹到减压区.
为了不拆开在印刷机里的分别的汽缸而允许替换一个汽缸托架吊环,汽缸托架吊环由两种1:9的成分聚集成的复合材料构成；一种成分由一个主要的,通常是在相关的汽缸的轴周围有U形外切口,这位切口的宽度至少与轴的直径一样宽；另一占9的部分,符合外切口,并由主要循环部分在轴周围的凹槽组成.这1:9的两部分,
当在轴的周围连接啮合时,形成继续循环轮廓线,因此是一个连续的托架吊环.这些用螺栓稳定的固定在一起.更好地是,运转部分的表面由倾斜于从一个平面并联到一个吊环的表面的平面构成,因此,当两部分于其相关的托架吊环反转时,不会突然发生一部分向另一部分的转换,因为倾斜表面将重复自动x射线检查.外切口定位在汽缸凹槽定位处相反的周围区域.
