APPARATUS AND METHOD FOR TRANSFER AND TENSION-CONTROL OF FLEXIBLE SUBSTRATE IN ROLL-TO-ROLL PRINTING EQUIPMENT

摘要

The present invention relates to an apparatus and method for flexible substrate transfer and tension control in a roll-to-roll printing machine, and more particularly, to a method and apparatus for flexible substrate transfer and tension control in a roll- To a flexible substrate transfer and tension control apparatus and method for a roll-to-roll printing machine. According to the present invention, there is provided an apparatus for absorbing a change in tension due to thermal deformation of a flexible substrate between printing units, and precisely controlling the tension of the flexible substrate by correcting the feeding speed of the flexible substrate in each printing unit Thereby minimizing the influence of thermal deformation and maintaining the best print quality.
