摘要： A sheet guide apparatus for use in a rotary printing press which is adapted for the smear and mark free transfer of sheets between two sheet holding and transfer systems, such as a pair of sheet-carrying cylinders or a sheet-carrying cylinder and circulating sheet conveyor. The sheet guide apparatus includes a sheet guide having a guide surface disposed beneath the transfer area, and a pneumatic system for blowing a positive pressure air stream in the direction of a transfer area or tangent point between the sheet holding and transfer systems. A further pneumatic system optionally may be provided for drawing or blowing air through apertures in the guide surface.
摘要翻译：一种用于旋转印刷机的片材引导装置，其适用于在两片片材保持和转印系统之间的片材的涂抹和标记自由转印，所述片材保持转印系统例如一对片材承载圆筒或载纸圆筒和循环片材输送机。纸张引导装置包括具有设置在转印区域下方的引导表面的纸张引导件，以及用于沿着纸张保持和转印系统之间的转印区域或切点的方向吹送正压气流的气动系统。可以提供另外的气动系统，用于通过引导表面中的孔拉伸或吹入空气。

摘要： An apparatus for fixing a sheet on the surface of an electrically conductive cylinder of a printing machine for processing sheets, in particular, a sheet-fed offset printing machine. The apparatus includes an electrode that extends over the width of the cylinder for creating an electric field for adhering the sheet to the surface of the cylinder and an air directing device for directing pressurized air streams against the sheet and preliminary positioning the sheet onto the cylinder prior to being acted upon by the electric field. Various alternative embodiments of the sheet fixing apparatus are disclosed.
摘要翻译：一种用于将片材固定在用于处理片材的印刷机的导电圆柱体的表面上的装置，特别是单张胶版印刷机。该装置包括在气缸的宽度上延伸的电极，用于产生用于将片粘合到气缸的表面的电场;以及空气引导装置，用于将加压空气流引导到片材上，并将片材预先定位在圆筒上被电场所影响。公开了片材定影装置的各种替代实施例。
