Aligning Paper Tray

Tray 1 receives paper or copy sheets of different lengths and widths, one size group at a time, in the direction of arrow 2, aligns their trailing edges and repositions one of their side edges.

Rear tray wall 9 is used to stop sheets of width x. Pairs of moveable stops 3,4 and 5,6, being actuated independently by solenoids 7 and 8 via mechanical linkages, stop sheets of widths y and z, respectively. Solenoids 7 and 8 are controlled by paper size. Thus, the leading edges of variably wide sheets are aligned at line 10.

To reposition a side edge of the fed-in sheets to a predetermined position, e.g., line 11, tray 1 is moved horizontally, as shown by arrow 12, for a fixed distance. After the alignment is completed, the stacked sheets can be refed into the machine.
