A process for preparing photosensitive resin cylinders which-comprises winding a photosensitive resin sheet on and around the surface of a cylinder without any material overlapping of or spaces between the edge portions of the wound resin sheet, and applying to the cylinder under rotation a roll rotating in contact with the surface of the resin sheet while heating so as to join the edge portions of the resin sheet to one another by melting and to make uniform the thickness of the resin sheet. |
