    • A sheet-fed, high-production, multi-purpose printing press assembled from a group of especially constructed components, including frames, cylinders, sub-assemblies, printing modules and removable and interchangeable segments, each being adapted to be assembled in a wide variety of combinations with the others to produce various simple configurations, to perform single printing functions with high efficiency, as well as various more complex configurations to perform a variety of printing functions and/or combinations of functions (in some cases including concurrent printing and collating); and the method of manufacturing a wide variety of different printing presses with diverse printing functions which involves the steps of first manufacturing a plurality of said especially constructed frames, cylinders, modules and other components, each constructed in such a manner that they may be combined together in a wide variety of configurations, and then assembling a wide variety of different printing presses from said especially constructed components; and with all of the printing functions and/or combinations of functions, including multicolor printing and/or perfecting, and/or concurrent printing and collating, being accomplished with each sheet passing through the press only once. The basic press structure includes a printing couple consisting of a standardized, especially constructed, lower printing cylinder, having a single work area, and an especially constructed large printing cylinder, having an effective diameter which is a whole multiple, greater than one, of the effective diameter of the lower printing cylinder, and having a number (equal to the whole multiple) of work areas, in each of which one of a variety of the especially constructed removable and interchangeable segments may be mounted. One of a variety of different printing surfaces may be carried in each of the various work areas on the cylinders of the printing couple, in a wide range of combinations. The printing couple is mounted in an especially constructed frame structure appropriate to the size of the large printing cylinder and constructed so as to provide a plurality of module mounting positions, at each of which one of a variety of especially constructed printing modules may be mounted in cooperative relationship with the large printing cylinder. The various especially constructed printing modules, in turn, are so constructed that they may each be mounted in any required module mounting position. The said printing modules provide means for mounting other printing surfaces and/or inking or inking and dampening rollers in cooperative relationship with the work areas of the large printing cylinder. The press includes especially constructed feeder means on one side of the printing couple and especially constructed delivery means on the other side of The printing couple, and selectively controllable means are available for causing sheets to be fed to every revolution, or to other than every revolution, of the lower printing cylinder, for causing a sheet to be carried through the bite of the printing couple, once or more than once, as it passes through the press and for causing the sheets to be delivered with a selected printed surface face-up. The efficiency and high productivity of the various configurations of the press are enhanced through the provision of a variety of especially constructed components which perform selectively controllable coordinating and control functions, so that maximum utilization is made of each revolution of the large printing cylinder in terms of the application of images to the sheets being printed, or concurrently printed and collated, in the light of the printing function or combination of functions being performed.

    • A roll for applying uniform pressure has a stationary inner structure mounted between two supporting shafts. A cylindrical outer structure surrounds the stationary inner structure and is rotatably mounted on the shafts. A plurality of inner rollers is disposed in a slot formed in the inner structure and contacts a colinear series of locations along the inside of the outer structure. An inflatable bag is disposed within the slot and, when inflated with a fluid, applies a uniform pressure to the inner rollers. These rollers prevent the outer structure from deflecting and cause it to apply a uniform pressure to an opposing surface.
    • 用于施加均匀压力的辊具有安装在两个支撑轴之间的固定内部结构。 圆柱形外部结构围绕固定的内部结构并且可旋转地安装在轴上。 多个内辊设置在形成在内部结构中的槽中,并且沿着外部结构的内部接触共线系列的位置。 充气袋设置在槽内,当用流体充气时,向内辊施加均匀的压力。 这些辊防止外部结构偏转并使其对相对的表面施加均匀的压力。
