Abstract
A sheet supplying unitsupplies sheets S one by one. A knife-type folding unitfolds the sheet. A first sensordetects the sheet entering the folding position. A second sensordetects the sheet passing through the opening. A timermeasures a time interval from end of sheet detection by the second sensor to start of sheet detection by the first sensor. A sheet feed interval change unitcalculates a reduction amount of the sheet feed interval using the measured values of the timer and changes the sheet feed interval based on the reduction amount each time a predetermined number of the sheets are folded.
