This invention relates to a paper sheet bending apparatus in a bag making machine. The apparatus of this invention is adapted to automatically adjust width sizes of a plurality of guide plates for bending a paper sheet by making use of the computer. The computer comprises a main computer including first memory means for storing sizes of various kinds of bags to be manufactured, and a correction value command computer connected to the main computer and including second memory means for storing a plurality of conditions of the paper sheet. By making use of this correction value command computer, fine adjustment of the guide place can be easily made. The main computer is connected to drive motors with an encoder through control units, etc. The output shaft of the drive motor is joined to the guide shaft laterally and axially supported by the frames. A screw body combined in one body with the guide plate for bending a paper sheet is movably provided in a horizontal direction on the guide shaft. A plurality of guide shafts and control units are provided in correspondence with the number of guide - 1 - 2 plates. The plurality of control units are connected to the main computer through a signal transfer unit. An employment of such a configuration makes it possible to automatically carry out an adjustment of width sizes of respective guide plates in a short time, and to manufacture high accuracy bags with a square bottom. - 2 -
