Abstract

PURPOSE:To forcibly press a sheet folding part uniformly on the whole, by setting up a conveying direction selector device in a folding roller pair holding a sheet in between so as not to be contacted even at the time of operation leading it into the folding pair, and forming a roller outer circumferential surface of the said folding roller pair into a flat surface. CONSTITUTION:When a twofold mode is being selected, a deflector 22 is selected to the side of a pair of folding rollers 21 and 25 (a full line position), while the sheet S conveyed to a conveying passage 15 comes into contact with a stopper 16 or 17 at its tip end and positioned right. And, a loop is formed in a center part of the sheet S, and the sheet is held between paired folding rollers 13 and 21, thus a fold P is formed in the central part of the sheet S. Next, it is guided by the deflector 22 and fed to these rollers 21 and 25, then pinched by a nip part consisting of these folding rollers 21 and 25 having the outer circumferential surface formed on the flat surface. And, the twofold sheet S is forcibly pressed uniformly at the fold P on the whole and fed to a conveying passage 29.
