摘要： A method of xeroprinting in which a master sheet is secured to a drum to create a drum-sheet unit. The drum-sheet unit is installed in a master-creating apparatus where a xeroprinting master is created on the master sheet. The drum-sheet unit is then removed from the master-creating apparatus and installed in a xeroprinting apparatus. The xeroprinting apparatus forms a visible image on the xeroprinting master. The visible image is transferred and fixed to a receiver sheet. This method may be used to make color prints. Several color separation xeroprinting masters are created and the toned images created from them are superimposed in registered alignment with each other onto a receiver sheet to create a multicolor print.

摘要： A recirculating document feeder for use with an electrostatographic apparatus for producing precollated or post-collated simplex or duplex copies from simplex or duplex original documents with a transport arrangement which simplifies operational control over the feeder and reduces the potential of damage to the original document sheets. The document feeder comprises a hopper for holding a stack of original document sheets. A transport mechanism is provided for respectively transporting an original document sheet along a path in which such sheet is removed in one direction from the stack hopper and delivered in such direction to an exposure station; or a path in which such sheet is removed in a direction opposite to the one direction from the stack hopper, turned over, and delivered to the exposure station. The transport mechanism is selectively controlled to carry out delivery of document sheets depending upon whether the original documents in the stack hopper are simplex or duplex. Further, an original document sheet is selectively clamped to a transport mechanism at the exposure station for recirculation or passed directly back to the hopper to respectively carry out pre-collation or post-collation copying.
摘要翻译：一种用于静电放映装置的再循环文件馈送器，用于通过传送装置从单面或双面原始文件生产预先胶合或后整理的单面或双面复印件，其简化了对馈送器的操作控制，并降低了对原稿的损坏的可能性。送纸器包括用于保持原稿的堆叠的料斗。提供了一种传送机构，用于沿着沿着一个方向从纸堆料斗中取出纸张的路径分别输送原稿，并以这种方向被输送到曝光站; 或者将这种片材从与料斗料斗一个方向相反的方向上移除的路径翻转并被输送到曝光站。选择性地控制传送机构，以根据堆栈料斗中的原始文件是单面还是双面的方式执行文件片材的传送。此外，将原始文件片选择性地夹持在曝光站处的运送机构用于再循环，或者直接返回到料斗以分别进行预对核或后对核复制。

摘要： An electrographic apparatus has a photoconductor in the form of an endless web, and latent images are formed on one side of the web. The photoconductor is advanced along a path past three development stations at which latent electrostatic images on the web can be developed with colored developer material from the stations. The web is mounted for travel along a path spaced from the three development stations with the latent images of the photoconductor facing the development stations as the web passes the development stations. A plurality of back-up rollers positioned on the side of the web opposite from the development stations can engage the web to move the web out of its path of travel spaced from the development stations into a position relative to any single one of the development stations so that a latent image can be developed by such station. The three development stations are located with respect to each other and the web to enable two of the back-up rollers to be moved to bring the web into a position relative to only two of the development stations so that said two of the development stations simultaneously apply developer material to latent images on the photoconductor with the web continuing to be spaced from the other development station. High productivity is achieved, and operation of the development stations can be stopped fast and reliably.
摘要翻译：电摄影装置具有环形纤维网形式的光电导体，并且在幅材的一侧上形成潜像。光电导体沿着通过三个显影站的路径前进，在该开发站处，可以利用来自站的彩色显影剂材料显影幅材上的静电潜像。当幅材通过显影台时，幅材被安装成沿着与三个显影站间隔开的路径移动，其中感光体的潜像面向显影站。位于幅材与显影台相对侧的多个支撑辊可以与纸幅相接合，以使纸幅从与显影台间隔开的行进路径移动到相对于任何一个显影站的位置从而可以通过这样的站来开发潜像。三个开发站相对于彼此和网络定位，以使得两个后备辊能够被移动，以使得网幅相对于仅两个开发站站的位置，使得所述两个开发站同时将显影剂材料应用于感光体上的潜像，其中纸幅继续与另一显影台间隔开。实现高生产率，快速，可靠地停止开发站的运行。

摘要： A sheet to be clamped includes registration holes at its edges. The leading and trailing ends of the sheet are superimposed, then positioned and clamped with respect to a cylinder by means of a clamping bar. The sheet is tensioned by use of an adjustable tensioner rod. Vernier-type scales on the sheet and cylinder aid in measuring and setting the desired tension. A longitudinal edge of the sheet is located by pins suitably located on the cylinder. In alternative embodiments, the clamping bar and tensioner rod are combined in a unit, or the clamping bar is formed in split sections to receive the sheet therebetween.

摘要： An endless imaging web is supported by a large diameter drum and at least one small diameter roller. First and second electrostatic images are created and toned on the same portion of the web as it is backed by the drum. The toners are of different color to create a multicolor image on the imaging web. The multicolor image is transferred to a receiving sheet, which receiving sheet is separated from the web as the web passes around the small diameter roller. Two small diameter rollers can be also provided which facilitate single-pass duplexing.

摘要： An endless transfer web is supported by a large diameter drum and at least one small diameter roller. Two or more imaging drums are positioned in transfer relation to the transfer web where it is backed by the large drum. Different color toner images are transferred in registration to the web to form a multicolor image which is transferred to a receiving sheet. The receiving sheet is separated from the web as the web passes around the small roller. The imaging drums can be electrophotosensitive drums with separate electrophotographic stations or drums which hold masters, for example, xeroprinting masters on their periphery.
