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.

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.
[5] Starting the second fold
Again, the opposing drives of drum and in-feed rolls
cause a loop, this time in the other direction.
