Abstract

A system for continuously storing and releasing flexible web material in an endless loop for a copier is disclosed. The web 1 can be a photoreceptor or a lithographic master or an intermediate or a support for originals being recirculated for pre-. collation copying. It could also be utilized for buffer storage of a long, magnetic tape endless ioop. This system is suitable for any application in which it is desirable to store a relatively long segment of a web in a compact yet controlled

WEB LOOP STORAGE (ConVd)

A system for continuously storing and releasing flexible web material in an endless loop for a copier is disclosed. The web 1 can be a photoreceptor or a lithographic master or an intermediate or a support for originals being recirculated for pre~. collation copying. It could also be utilized for buffer storage of a long, magnetic tape endless ioop. This system is suitable for any application in which it is desirable to store a relatively long segment of a web in a compact yet controlled

manner, releasing only that portion of the web which is to be processed at any given time. Unlike systems in which the stored portion of the web loop is dumped into a bin where it may be subjected to uncontrolled bending, twisting or contact, the present system provides positive support and control over the bending and spacing of all of the web at all times.

As shown, the web 1 is stored by stacking it in a series of supported and controlled moving ioops which continually take in and feed out the desired amount of the web 1 to the desired process unit 2. The unused portion of the web 1 is maintained in a stacking unit 3 which is shown in a side view in Figure 1 and a partial top view in Figure 2. The stacking unit 3 generally consists of four sets of moving loop hangers 4 and two shuttle roll pair assemblies S and 6. The loop hangers 4 are spaced along and recirculate endlessly on supporting belt 7 at opposite sides of the web I at the desired top and bottom positions of the web loops which they define, The web I is weaved onto the loop hangers 4 by the input shuttle 5 at the input end of the stacking unit 3. The web is thus supported from its sides at e...
