Abstract: Mechanism for controlling sheet manipulators, including sheet guides, in a perfector press, when the press shall be switched from obverse-obverse to obverse-reverse printing, or vice versa. A first printing cylinder and an adjacent transfer cylinder of the press have linkages pivoted about the respective cylinder axes and swingable, relative to the cylinders, in coordinated and partly overlapping motions. The linkage of the first printing cylinder repositions a sheet guiding plate by crank, link and guide units. It also repositions the sheet gripping mechanism of the first cylinder and, with lost motion, that of the transfer cylinder. Exact positioning of all mechanisms are provided by detent and release means in the transfer cylinder.

Abstract translation: 当印刷机从正面转向正反转印刷时，在整体印刷机中控制纸张操纵器（包括纸张引导件）的机构，反之亦然。 压力机的第一印刷滚筒和相邻的传送滚筒具有围绕相应的滚筒轴线枢转的联接件，并且可相对于滚筒以协调的和部分重叠的运动摆动。 第一印刷滚筒的连接通过曲柄，连杆和引导单元重新定位片材引导板。 它还重新定位了第一个气缸的纸张夹紧机构，并且随着运动而转移到传送滚筒的位置。 所有机构的精确定位由传动滚筒中的定位和释放装置提供。
