APPARATUS FOR REMOVING SCALE ADHERED TO SURFACE PART OF REVERSE DIRECTION THREE ROLL-TYPE COATING ROLL AND PREVENTING OVERFLOW OF SOLUTION, COMPRISING BENT PLATE SEPARATED FROM SOLUTION PICK-UP ROLL AND BELT-TYPE WOOL FABRIC

摘要

PURPOSE: Provided is an apparatus for removing the scale adhered to the surface part of a reverse direction three roll-type coating roll and preventing the overflow of a solution without line stop for reducing the coating defect due to scale and the working hindrance due to the bubble of solution. CONSTITUTION: The apparatus comprises a bent plate(50) which is separated and located at the upper part between a solution pick-up roll(3) and a solution thickness control roll(2) and has a sponge adhered to the lower part; a belt-type wool fabric(22) having a roller(23) whose one side is fixed to the bent plate and which is mounted at its one side and rotates by the rotation force delivered from the rotation axis(32) of the solution pick-up roll. Preferably the apparatus comprises further a ventilator(24) and an inhalator(25) which receive the belt-type wool fabric from between them to squeeze the solution.
