摘要： A system for duplicating images wherein a copy sheet is delivered to a first gripper of an impression cylinder. A first image is transferred to one side of each sheet, and each sheet is then released by the first gripper and delivered to a reversing means. A second gripper includes means for engaging the trailing edge of each sheet and the sheets are thus re-fed to the impression cylinder by this second gripper, trailing edge first. The re-feeding is in synchronism with the second image whereby this second image is transferred to the opposite side of each sheet. The second gripper is provided with inverting means to accommodate the re-feeding. In addition, separate gripper means are provided on the second gripper for engaging the trailing edge of a succeeding sheet whereby the second gripper simultaneously engages the trailing edge of one sheet and the formerly trailing edge of a previously introduced sheet.

摘要翻译： 一种用于复制图像的系统，其中复印纸被传送到压印滚筒的第一夹持器。 第一图像被转印到每个纸张的一侧，然后每个纸张被第一夹持器释放并且被递送到换向装置。 第二夹持器包括用于接合每个片材的后缘的装置，并且片材因此被第二夹持器首先重新馈送到压印滚筒。 重新进给与第二图像同步，由此将该第二图像转印到每张纸的相对侧。 第二夹持器设置有反转装置以适应再进给。 此外，在第二夹持器上提供单独的夹持装置，用于接合后续片材的后缘，由此第二夹持器同时接合一片的后缘和先前引入的片的先前后缘。

摘要： A master cylinder for an offset or the like printing press includes an arcuate master receiving surface extension section mounted on the cylinder for movement between an inoperative position into the interior of the cylinder and an operative position adjacent the tail end of the stationary master receiving surface of the cylinder. When in the operative position the extension section increases the length of the master sheet receiving surface of the cylinder to accommodate longer than "standard" length master sheets. The extension section is mounted for sliding movement on arcuate guides formed by the movement of a predetermined radius extending from a point off center with respect to the central axis of the cylinder. A locking assembly is included to secure the section in either position. A tail clamp for longer masters is provided on the free end of the extension section. The standard tail clamp is also mounted for movement from an inoperative position adjacent the tail end of the stationary master receiving surface of the cylinder to a position within the cylinder to permit movement of the extension section to an operative position. In a preferred embodiment, a pivotal assembly within the cylinder is coupled both to the extension section and the standard tail clamp to move the latter into an inoperative position simultaneously with the movement of the extension section to an operative position and vice versa.
