<p>The present invention relates to a cantilever type roll-to-roll device. The purpose of the present invention is to provide a spiral vibration preventing structure of the cantilever type roll-to-roll device capable of absorbing vibration generated when a roll rotates at high speeds to prevent a transmission of vibration by spirally installing a vibration absorbing pad on a guide holder utilized to couple the roll and a bearing to a cantilever beam of the cantilever type roll-to-roll device, preventing damage to the roll and a rupture of the roll by preventing a resonance phenomenon that the vibration generated in the roll is transmitted to the cantilever beam, and improving workability by stably rotating at super precision when processing a super precise film. In the cantilever type roll-to-roll device composed of the roll formed into a shaft type for precise rotation having one end from which a coupling unit with a decreased diameter is integrally extended, the ring-shaped bearing to couple the coupling unit of the roll, the flange-shaped guide holder having a coupling piece wherein a coupling groove to couple and fixate the bearing, and the cantilever beam on which the guide holder is joined and fixated; the present invention is characterized by including a spiral guide groove on an outer circumference of the coupling piece of the guide holder in a circumferential direction, and the spiral vibration absorbing pad to be inserted and joined to the guide groove.</p> |
