(C) Cross Folding
Cross folding refers to performing the double
parallel, letter, or other types of folds for the
sheets of paper folded using the single folding
method.
Cross folding can be used if, for example, the
sheet of A3-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 105g/m
2
.
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 broken down.
Note:
Press the crease hard using the hand. Do not
stack too many sheets of paper on the paper feed
table.
