<P>PROBLEM TO BE SOLVED: To provide an improved system and method for securing printing plates on a cylindrical drum, and maintaining proper tension on the printing plates. <P>SOLUTION: A method and apparatus of securing and tensioning a printing plate in an apparatus having a rotatable drum includes: a step of securing a first portion of the printing plate to a first receiving device that is coupled to a surface of the drum; and a step of securing a second portion of the printing plate to a second receiving device that is disposed on a rotatable member that extends over a portion of the drum. The rotatable member is rotated so that the circumferential distance between the first receiving device and the second receiving device is about the same as a length of the printing plate. A rotary torque device is coupled to the rotatable member to apply a substantially constant torque on the member and tension the printing plate about the surface of the drum. The rotary torque device adjusts torque on the member, thereby adjusting tension on the printing plate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
