摘要： A system for decurling a sheet which is being advanced in a predetermined path within a printing machine includes a mechanism for generating a flow of room ambient air. The decurling system further includes a mechanism for directing the flow of room ambient air onto the sheet. Moreover, the decurling system includes a decurler adapted to apply mechanical force to the sheet after the flow of room ambient air has been directed onto the sheet by the directing mechanism. Finally, a mechanism is included for rotating the sheet to advance the sheet to the decurler in a direction substantially perpendicular to the direction of the predetermined path.

摘要： A printing apparatus places multiple images on a sheet, either by re-feeding the sheet through a duplex path back to a marking device, or by feeding the sheet to successive marking devices. An edge position detector upstream of the marking device determines the location of the sheet so that an image may be precisely placed on the sheet. The system ensures that images on both sides of a sheet are in registration with each other.
摘要翻译：打印设备通过将片材通过双面路径重新馈送回到标记装置，或者通过将片材馈送到连续的标记装置，将多个图像放置在片材上。标记装置上游的边缘位置检测器确定片材的位置，使得可以将图像精确地放置在片材上。该系统确保纸张两面的图像彼此对齐。

摘要： An idler system that is both self-centering and self-aligning with a drive roll. The idler assembly consists of a pair of rolls connected by a shaft, the shaft being supported in a housing. The housing is retained by a resilient spring member which member allows the axis of rotation of the idler rolls to pivot in more than one plane simultaneously. This pivoting causes the axis of rotation of the idler assembly to align parallel with the drive roll axis. The single spring also provides an even loading of the normal force across the width of the drive nip. As a result of the alignment and even loading, skewing of a sheet is prevented as it is driven through the nip formed by the drive roll and the idler roll. The resilient spring mounting also allows for easy replaceability of the idler assembly and the housing is easily locatable between tabs formed in the frame of the machine for mounting the idler assembly therein. The housing provides a guide from the mounting frame into the nip and from the nip into the downstream paper path for increased capacity to handle curled and/or damaged cut sheet media.
摘要翻译：一个惰轮系统，既可以自动定心，也可以使用驱动辊自动对准。惰轮组件由一对由轴连接的辊组成，轴被支撑在壳体中。壳体由弹性弹簧构件保持，该构件允许惰辊的旋转轴线在多于一个平面中同时枢转。该枢转导致惰轮组件的旋转轴线与驱动辊轴线平行地对准。单个弹簧还提供穿过驱动压区宽度的法向力的均匀加载。作为对准和均匀加载的结果，当通过由驱动辊和惰辊形成的辊隙驱动时，防止片材的偏斜。弹性弹簧安装件还允许惰轮组件的易于更换，并且壳体可容易地定位在形成在机器框架中的凸片之间，以将惰轮组件安装在其中。壳体提供从安装框架到辊隙和从辊隙到下游纸路径的引导件，以增加处理卷曲和/或损坏的切割片介质的能力。
