PURPOSE:To prevent the folding back of a folded material, and to prevent the jamming of the folded material by providing a stopper provided on the side opposed to the folded material of a support bar, and a paper keep formed on one end of a shaft part supported by the support bar in such a way that the press keep is freely slid. CONSTITUTION:A paper keeping device 4 is mounted on a support bar 1 through a bracket 2, and each two and total four paper keeping devices 2 are mounted on the bracket 2 perpendicular to a table surface A of a table 33. The center part of its shaft 7 is supported by a keeping pressure adjustment handle 6 screwed into a screw 15 provided on the bracket 2, in such a way that the center part of the shaft is freely slid, while a block-like brake shoe 11 is fixed to the end part opposed to the table 33 of the shaft 7. A compressed coil spring 12 is provided, and the keeping pressure adjustment handle 6 is rotated, so as to press the shaft 7, i.e., the brake shoe 11 vertically, and the pressure is thus adjusted. A plurality of plate-shaped stoppers 13 are provided in the width direction between the support bar 1 and the brake shoe 11. |
