Device for transferring film

Abstract

A device for transferring a film is provided. The device includes a roller transferring a film; a balancing unit connected to the roller by fixed supporters, the fixed supporters being disposed on both sides of the roller; and springs disposed on both sides of the balancing unit, wherein, if the film is out of balance, the balancing unit restores balance to the film by vibrating the both sides of the balancing unit. That is, if a film becomes out of balance during the transfer of the film, the device may restore balance to the film with the aid of the balancing unit which can vibrate on both sides of the balancing unit due to the springs.

1 . A device of transporting a film, the device comprising:
 a roller transporting a film;   a balance unit connected with the roller by fixed supports installed at both sides of the roller; and   springs installed at both sides of the balance unit,   wherein the balance unit compensates a balance of the film by oscillating the both sides of the balance unit up and down when the film is out of balance.   
   
   
       2 . The device of  claim 1 , wherein the balance unit comprises:
 a compensating bar connected with the fixed support; and   a fixed bar connected with a lower part of the compensating bar by a spindle,   wherein both sides of the fixed bar is connected with both sides of the compensating bar by the springs, and the both sides of the compensating bar oscillates up and down.   
   
   
       3 . The device of  claim 2 , wherein the spindle comprises;
 a bearing; and   an axle connecting the compensating bar to the fixed bar through the bearing.   
   
   
       4 . The device of  claim 2 , wherein the fixed bar is connected with a middle lower part of the compensating bar by the spindle. 
   
   
       5 . The device of  claim 1 , further comprising,
 a spindle connecting the roller to the fixed supports,   wherein the spindle is spaced a predetermined distance apart from a central axis of each of the springs.
