摘要： A charging device comprises a housing defining a charging chamber. Two tensioning shafts are mounted on opposite ends of the housing. The charging device comprises a control grid attached to the grid tensioning shafts, thus substantially covering the chamber opening. The control grid is comprised of a conductive material capable of being stretched along its length. As a result, the grid becomes flat when opposing rotating forces are applied to the two tensioning shafts.

摘要： A sheet handling system for a sheet transport path of a reproduction apparatus having a sheet skew correction system being fed image substrate sheets in the process direction by a sheet transport system, wherein it is desired to positively feed and yet effectively deskew a wide range of different lengths of sheets in the process direction. A plurality of identical but independent sheet transport units may be provided spaced along the sheet transport path in the process direction engageable with a sheet being fed through sheet transport path for positively feeding even very short sheets from one sheet transport unit to another and to the skew correction system. Yet these sheet transport units provide independently automatically disengageable nips for automatically releasing even a very long sheet from any unit when that long sheet is in the skew correction system. A different selected number of the sheet transport units are disengaged in response to a different sheet length control signal. A single stepper motor rotating a common camshaft in each unit may be used to reliably lift all the idlers of all the nips to be disengaged.

摘要： A corotron assembly comprising a coronode for generating an electrostatic field and including an electrically nonconductive protective guard having a U-shaped base member forming a channel for receiving the coronode wherein a plurality of finger elements are provided, extending from the sidewalls such that the coronode is recessed between the finger elements. Each finger element is further provided with a spherical radii tip for reducing the attenuating effects of the finger elements on the electrostatic field generated by the coronode.

摘要： A sheet handling system for correcting the skew and/or transverse position of sequential sheets, especially those moving in a process direction in a sheet transport path of a reproduction apparatus to be registered for image printing, of the type in which the deskewing and/or side registration is accomplished by partially rotating the sheet with a transversely spaced pair of differentially driven sheet steering nips. The effective range of sheet size capabilities of such systems may be increased without steering nip slippage or other problems by applying a control signal proportional to the width of the sheet to a system for automatically increasing or decreasing the transverse spacing between the pair of sheet steering nips, so as to provide a much wider spacing for larger sheets yet still be able to handle small sheets. This may be provided as shown by automatically engaging only a selected pair of steering nips out of a selectable plurality of different fixed position sheet steering nips and disengaging the others by lifting their idlers out of the sheet path with cams rotated by a stepper motor with a rotation controlled by the sheet width signal.
摘要翻译：一种纸张处理系统，用于校正顺序纸张的偏斜和/或横向位置，特别是在要注册用于图像打印的再现设备的纸张传送路径中沿处理方向移动的顺序纸张的偏斜和/或横向位置，其中偏移和/或侧面对准是通过以横向间隔开的一对差动驱动的片状转向辊隙部分地旋转片材来实现的。可以通过将与片材的宽度成比例的控制信号施加到系统来自动增加或减小一对片材转向辊隙之间的横向间隔，可以增加这种系统的片材尺寸能力的有效范围，而不会产生转向辊隙滑移或其他问题，以便为较大的片材提供更宽的间隔，但仍然能够处理小片材。这可以被提供，如通过仅仅从可选择的多个不同的固定位置片材转向辊隙中选择的一对转向辊隙自动地接合而提供的，并且通过用步进电动机旋转的凸轮将它们的惰轮提升出纸张路径，旋转由纸张宽度信号控制。
