摘要： A duplicating system for producing collated copy sets from precollated information. The precollated information is stored on a reversibly driven and reversibly developed web member which is driven past a first copy transfer station when moving in a first direction and past a second copy transfer station when driven in a reverse direction. A development station is positioned in the path of the web to develop the precollated information thereon when the web is moving in either direction. Copy sheets are fed by a first transport past the first transfer station to produce copies thereof when the web is moving in a first direction. Copies are fed by a second transport past the second transfer station to produce copies from the developed web member when the web is moved in a reverse direction. The copies are fed to a first copy receiving tray face down when the web is moving in one direction and to a second copy receiving tray face up when the web is moving in a reverse direction. In this manner, two stacks or sets of copies are reproduced in collated order from the precollated information on the web. Upon repeating the steps of the duplicating process additional copy sets in precollated order can be obtained. The web may take the form of a lithographic master, a magnetic tape, flexographic master or a xeroprinting master.
摘要翻译：用于从预分类信息生成整理副本集的复制系统。预分解信息存储在可逆地驱动和可逆地展开的卷材上，当沿相反的方向驱动时，其沿第一方向移动并经过第二复印传送站时被驱动经过第一复印传送站。当纸幅沿任一方向移动时，显影台被定位在纸幅的路径中以便展开其上的预分解信息。当纸幅沿第一方向移动时，复印纸通过第一传送装置通过第一传送站进行馈送以产生其副本。当纸幅沿相反方向移动时，副纸通过第二传送站进给，以从展开的卷筒纸部件产生副本。当纸幅沿相反的方向移动时，当纸幅在一个方向上移动时，这些纸张面朝下地被馈送到第一复印接收纸盘，并且当纸幅向相反方向移动时，副本被朝下放到第二复印接收盘。以这种方式，从网络上的预分解信息按照整理顺序复制两个堆叠或一组拷贝。在重复复制处理的步骤之后，可以获得预分层次序的附加拷贝集。纸幅可以采用平版印刷母版，磁带，柔版印刷母版或印刷母版的形式。
