METHOD AND APPARATUS FOR TENSIONING A PRINTING FORM |
摘要 |
A method and apparatus of securing and tensioning a printing form in an apparatus having a rotatable drum includes securing a first portion of the printing form to a first means for receiving that is coupled to a surface of the drum, and securing a second portion of the printing form to a second means for receiving 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 means and the second receiving means is about the same as a length of the printing form. A rotary torque means is coupled to the rotatable member to apply a substantially constant torque on the member and tension the printing form about the surface of the drum. The rotary torque means adjusts torque on the member which adjusts tension on the printing form.
