Title: Coating method and coating device
Inventor: UEHARA SOUICHI
IPC: B05D1/02
Filed: 1979-05-22
Abstract: PURPOSE: To prevent the pale coating of low density by shutting off the low-density portion only for a short time just before the starting and ending of coating.  
     CONSTITUTION: Before the starting of coating, a shutter 1 and coating material flow-down cock 2 are held fully closed. Upon starting of the coating, the shutter 1 and flow-down cock 2 are fully opened and the coating machine is moved to the right direction as shown by the arrow B. In this case, the high-density layer (a) follows after the low-density layer (b) and therefore uneven coating does not occur. Next, the shutter 1 is closed by leaving the high-density portion just before ending of the coating. Hence, the pale portions at the terminal end of the coating are eliminated. Next, both shutter 1 and flow-down cock 2 are fully closed upon ending of the coating. At the time when the coating machine moves relatively in the direction opposite from the arrow B, that is, in the direction opposite the tangential speed direction of the roll, the shutter covers the low-density part at the start of coating, thence it is fully opened and at the ending of the coating, it is fully closed.
