摘要： A reversing or turning assembly of a sheet-processing machine includes an impression cylinder having a circumferential surface for transporting sheets thereon for printing the sheets in a printing nip associated with the impression cylinder. Gripper devices are provided for gripping the printed sheets at a respective trailing edge thereof and for lifting the gripped sheets off the impression cylinder for reversing the gripped sheets. The circumferential surface of the impression cylinder is formed with recesses in a region thereof occupied by the trailing edge of the sheets, for permitting the gripper devices to penetrate or dip into the recesses to grip the sheet trailing edge. The recesses have a position being variable in circumferential direction of the circumferential surface of the impression cylinder for adapting to different sheet formats.

摘要： A machine processing printing-material sheets contains a first sheet transport drum and a second sheet transport drum disposed immediately after the first sheet transport drum in a sheet transport direction. The first sheet transport drum has gripper systems which describe a gripper flight circle during its rotation and a drum profile deviating substantially from a circular shape with outer contour regions running between the gripper systems and set back from the gripper flight circle. The second sheet transport drum has a sheet support surface with pneumatic grooves formed therein. The sheet support surface is composed of a first and second comb segments each with segment prongs. The pneumatic grooves are introduced into the segment prongs of at least one of the comb segments. The pneumatic grooves are preferably introduced both into the segment prongs of the first comb segment and into the segment prongs of the second comb segment.
摘要翻译：机械加工印刷材料板包含第一片材传送滚筒和在片材传送方向上紧邻第一片材传送滚筒之后的第二片材传送滚筒。第一片材传送滚筒具有夹持器系统，其在其旋转期间描述夹持器飞行圆圈，并且滚筒轮廓基本上从圆形形状偏离，其中外轮廓区域在夹持器系统之间延伸并从夹持器飞行圆圈返回。第二片材输送滚筒具有在其中形成有气动槽的片材支承表面。片材支撑表面由每个具有片段插脚的第一和第二梳状部分组成。气动槽被引入至少一个梳状段的分段插脚中。气动槽优选地被引入到第一梳状部分的分段插脚中并进入第二梳状部分的分段插脚。
