Xerox 2750 manual Starting the second fold, Accordion fold compensating panels

Page 32

The drum continues to rotate clockwise, stopping at the point [4], where the distance between the folded edge (C) and the lower fold roll again equals the selected accordion panel width. At this point the drum reverses [5], this time developing a down-going loop (D) which in turn becomes trapped by the lower fold roll to make the second fold.

[5] Starting the second fold

Again, the opposing drives of drum and in-feed rolls cause a loop, this time in the other direction.

The clockwise/counter-clockwise sequence then repeats until the entire document is folded, the last fold being positioned (in the standard accordion fold program) to deliver two equal-width compensating panels.

Accordion fold compensating panels

These may be aligned with either the left or right edges of the packet, depending on the combination of panel width, S, and the overall length of the document.

The end panels of the accordion fold are narrower than the selected panel width (S), unless the length of the document - as measured automatically by the bridge and in-feed system - happens to be an exact multiple of width S.
