PURPOSE: To accurately and easily fold cut paper double in a post-process by preliminarily forming a fold to the cut paper. CONSTITUTION: The drive roller 4 connected to a paper feed motor 3 and a paper press roller 5 are supported in a mutually pressurized state. The drive roller 4 is formed from material quality having elasticity and a projection 5a is formed to the paper press roller 5 over the entire periphery thereof at the center position in the axial direction of the roller 5. When roll paper 13 is sent to the nip between the drive roller 4 and the paper press roller 5, the roll paper 13 is pressed by the projection 5a and a fold is applied to the roll paper 13. By adjusting the position of the fold so that the fold is set to the center line in the lateral direction of the roll paper 13, an accurate center position is marked on the cut paper cut in a post-process. |
