<P>PROBLEM TO BE SOLVED: To solve a such problem that paste containing a high polymer material is fiberized to become clayey when receiving shearing force by a pump or the like and can not be properly applied as a result. <P>SOLUTION: The high polymer material has a characteristic of hardly being fiberized when used at a temperature equal to or below a glass transition point and by taking the advantage of the characteristic, the pump 22 and a part of piping 26 in the upstream side is covered with a cooling device 128, and the paste PA is applied from a coating apparatus while keeping the temperature of the paste PA passing through the pump 22 to equal to or below the glass transition point of the water repellent material by the heat exchange in the cooling device128. <P>COPYRIGHT: (C)2008,JPO&INPIT |
