Cross Folding:
Cross folding refers to performing the double parallel, letter, or other
types of folds on single-folded sheets of paper.
Example:
11” × 17” sheet is folded in half, and then cross-folded to letter size to
fit into a standard # 10 envelope.
Note:
The maximum weight of paper that can be used for cross folding is 28#.
However, the following variables may affect performance of the paper
stock being folded: paper type, paper size, grain direction, printing
quality, as well as the relative humidity and temperature of the operating
environment.
On occasion, fold displacement may occur, causing a corner of the
folded paper to be folded inside as indicated in the figure at the right. In
these cases, additional fine adjustment may need to be made to the fold
tables to eliminate the problem.
Tip:
To aid in the cross-folding procedure, press the crease of the
single-folded stock flat before attempting to cross fold.
