A sheet processing device can prevent a folded sheet bundle from being opened upon accumulation to prevent a reduction in accumulation amount thereof. The sheet processing device includes a pair of pressing rollers pressing a folding loop of a folded sheet bundle in a thickness direction, a support unit mounted to a device frame and supporting a plurality of rows of the pressing roller pairs such that intervals therebetween in the row direction are reduced stepwise, and a gripper member that makes the folding loop of the folded sheet bundle pass through the support unit in a direction that the intervals of the plurality of rows of pressing roller pairs in the row direction are reduced stepwise. The folded sheet bundle passes through the support unit by the gripper member to cause the folding loop to be sequentially pressed by the plurality of rows of pressing roller pairs.
A sheet processing device that presses a folded sheet bundle, comprising:
A sheet processing device that presses a folded sheet bundle, comprising:
A sheet processing device that presses a folded sheet bundle, comprising:
A sheet pressing method of a sheet processing device including a device frame, a pair of pressing members that press a folding loop of a folded sheet bundle in a thickness direction thereof, a support unit that is mounted to the device frame and supports a plurality of rows of the pressing member pairs such that intervals therebetween in the row direction are reduced stepwise, and a moving member that makes the folding loop of the folded sheet bundle pass through the support unit in a direction that the intervals of the plurality of rows of pressing member pairs in the row direction are reduced stepwise, wherein the moving member conveys the folded sheet bundle so as to make the folding loop of the folded sheet bundle pass through the support unit for stepwise pressing of the folding loop.
