Abstract

The described method and apparatus for collating sheets, serially received in sets of identical sheets, require only one stacker tray. Identical first sheets are stacked partly overlapping each other, followed by second identical sheets that are also stacked partly overlapping each other, etc. The sets thus obtained are separated by pulling out the outermost set, while pressing down the remaining sets. Fig. 1 is an exploded view of how the sheets are stacked in an offset form, alternately from left to right and from right to left, partly overlapping each other. Fig. 2 is a front view of sheets thus stacked. In the simplest embodiment, the sets are separated by hand in the same way as sheets are pulled out of multiple forms.

Method and Apparatus for Collating

The described method and apparatus for collating sheets, serially received in sets of identical sheets, require only one stacker tray. Identical first sheets are stacked partly overlapping each other, followed by second identical sheets that are also stacked partly overlapping each other, etc. The sets thus obtained are separated by pulling out the outermost set, while pressing down the remaining sets. Fig. 1 is an exploded view of how the sheets are stacked in an offset form, alternately from left to right and from right to left, partly overlapping each other. Fig. 2 is a front view of sheets thus stacked. In the simplest embodiment, the sets are separated by hand in the same way as sheets are pulled out of multiple forms. The set beyond the one to be pulled out is pressed down on the stacker tray with one hand (left portion, Fig. 2), while the outermost set is seized with the other hand (right portion, Fig. 2) and pulled out. Seizing the sets is facilitated by providing the tray with a central recess. An apparatus for implementing the above-described method is shown in the perspective view of Fig. 3. The copier, designated as 31, comprises an exposure station 32 for the originals. Beneath copy exit 33, the upper portion of which has been omitted, there is a collator 34 comprising a stacker tray 35 which is either reciprocally movable in steps in a longitudinal direction (one step per copy) or continuously perpendicular to the ...
