Operation
As fanfold paper is output from the swinger, the assisting arms respond to the
actions of the swinger, and fold the paper at the perforations. The transfer
belts press the paper, stacking it on the elevator table. As paper accumulates
on the elevator table, the table lowers to keep the height of the paper uniform.
NOTE: The assisting arms are not activated when the head-to-tail length of
the sheet is 7 to 8.5 inches.
