Coating apparatus and coating method

The mounting is formed by grinding an integrally molded material with accuracy of the mum order. An upper portion of the mounting is an L-shaped holding portion on which a slot die is positioned. An upper face of the holding portion contacts a lower facer of the slot die, and a side face of the holding portion contacts a rear face of the slot die. The lower and rear races of the slot die and the upper and side faces of the holding portion are formed to have such a straightness for the total length that the unevenness thereof may be in 5 mum. Thus the slot die can be held with high accuracy, and the clearance accuracy between the lips and a web can be increased.
