(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
