This paper describes paper feeding and folding system in automatic post-treatment of duplicating work, such as fold, punch and seal treatment. In the paper feeding system, the occurence of miss feeding and piled paper feeding has been confirmed that it would be contributed to the increasing feed resistance, for adhere force of paper each other. This adhere force depends on the static-electric force that is mainly caused by the paper friction, this static-electric force has also been confirmed that it depends on rather the surface condition than the electric resistance of paper.
In the copied paper folding system, there have several kind of unique treatment, such as parallel folding of large size paper, folding back of paper edge, folding down of Z shaped style and rotation of feeding direction etc.
