TENSIONLESS ROLL TO ROLL APPARATUS AND METHOD FOR TRANSPORTING A MATERIAL USING THE SAME

摘要

A tensionless roll to roll apparatus and a transfer method for therewith are provided to prevent a film from expanding due to tension by transferring the film in a tensionless way. A tensionless roll(100) to roll apparatus includes an unwinding roll(11), a winding roll(14), and a conveyer unit(20). The unwinding roll winds a film, and then unwinds the film to transmit to the winding roll. The winding roll winds the film unwound from the unwinding roll. The conveyer unit is arranged between the unwinding roll and the winding roll and transmits the film from the unwinding roll to the winding roll in a tensionless way.
