Abstract
When a sheet bundle is being conveyed by any one pair of plural pairs of rollers independently movable toward and away from the bundle sheet, before the bound portion of the sheet bundle passes the pair of rollers, the pair of rollers on the downstream side nearest to the bound portion are separated from the sheet bundle, and the pairs of rollers more downstream than that pair convey the sheet bundle. Thereby, it happens less often that the pairs of rollers gather the air collected between adjacent ones of the sheets of the sheet bundle to the bound portion to thereby cause a slack to the sheets, and the occurrence of wrinkles or twists in the sheet bundle can be reduced. Also, the pair of rollers are separated from the sheet bundle before the bound portion passes the pair of rollers, whereby it happens less often that the pair of rollers are damaged by the bound portion, and the sheet bundle can be conveyed smoothly.
