<p>PURPOSE:To eliminate wrinkles of a sheet of paper, by forming helical grooves in a circumferential surface of each roll so that the opposite sides of the paper may be pulled outwardly, in an apparatus for delivering a sheet of paper through two paper delivering rolls by rotating the rolls. CONSTITUTION:The paper delivering apparatus delivers the paper through the paper delivering rolls 1, 2 by the rotation of the rolls 1, 2. For example, the paper delivering roll 1 includes a roll shaft 3, a metal roll body 4 secured thereto, and a thin sheath 5 secured to the outer circumference of the roll body 4. The roll body 4 is formed with the clockwise helical groove 6 in the right hand circumferential surface and the counterclockwise helical groove 7 in the left hand circumferential surface. On the other hand, the paper delivering roll 2 is constructed similarly to the roll 1 except that its helical grooves 11, 12 are reversed to the corresponding helical grooves 6, 7. Accordingly, the paper can be delivered with the opposite sides thereof pulled outwardly of the paper delivering rolls 1, 2.</p> |
