    Abstract: A duplicating machine for duplicating printed material from selected master cards onto a workpiece comprises a master card feed station including a feed device for feeding cards to a print station and a workpiece feed station including a device for feeding workpieces to a moistening apparatus and to the print station. Also provided is a card reading device for detecting predetermined information characteristics stored on an adjacent master card in a stack and for determining whether the printed material on that card is to be duplicated. If the material is to be duplicated the reading device provides a signal to a control system that actuates the workpiece feed device for feeding the workpiece to the print station. As the workpiece is fed from its feed station, it actuates an envelope feed detector which provides a signal that operates a common drive arrangement that actuates the moistening apparatus and the master card feed device whereby the master card and a moistened workpiece arrive at the print station for duplicating the printed material from the master card onto the workpiece. If the printed material on the card being read is not to be duplicated, the reading device provides another signal that operates the common drive arrangement so that only the master card is fed to the print station whereby the printed material is not duplicated.

    Abstract translation: 用于将选定的主卡打印的材料复制到工件上的复印机包括一个主卡进纸台，该主卡进纸台包括一个用于将纸张供给到打印站的进给装置和一个包括用于将工件供给润湿装置和打印装置的工件进给台 站。 还提供了一种用于检测存储在堆叠中的相邻主卡上的预定信息特征并用于确定该卡上的打印材料是否被复制的读卡装置。 如果要复制材料，则读取装置向控制系统提供信号，该控制系统致动工件进给装置，以将工件送入打印站。 当工件从其进料站进给时，其致动包络进料检测器，其提供操作共同的驱动装置的信号，其驱动润湿装置和主卡进给装置，由此主卡和润湿的工件到达打印站 用于将打印材料从主卡复制到工件上。 如果正在读取的卡上的打印材料不被复制，则读取装置提供操作公共驱动装置的另一个信号，使得只有主卡被馈送到打印站，从而印刷材料不被复制。
