(C) Cross Folding
Cross folding refers to performing the double parallel,
letter, or other types of folds for the sheets of paper
already folded in the single fold.
Cross fold ing can be used if, for example, a sheet of
ledger size paper folded using the double parallel
folding method is still too large to be enclosed in
envelope.
Note:
The maximum weight of paper that can be used for
cross folding is 28lb bond.
This requirement, however, varies according to the
following conditions:
Paper type; Paper size;
Whether grains run lengthways or sideways;
Temperature and relative humidity;
Printing condition.
The folding position may be displaced to a greater
extent than when the paper is folded using a regular
fold method, or a corner of the folded paper may be
folded inside as indicated in the figure. These,
however, do not mean that the machine has
malfunctioned.
Note:
1.) Move the paper feed rollers on both sides to
proper position in advance so that all of the
rollers can feed paper stock.
2.)
Flatten the crease hard using the hand. Do
not stack too many sheets of paper on the
feed table.
3.)
Use paper support guide(s) to 15 help hold
paper down
