塗布装置
Document Type and Number:
Japanese Patent JP3615637
Kind Code:
B2
Abstract:
A coating method and coating apparatus capable of providing a coated film (7) of improved surface properties free from any streak and color shading and facilitating coating on a sheet material (1) of an increased width without causing enlargement of the apparatus and thus complicating its structure. A swirling motion imparting mechanism (33) and an orifice (39) are arranged at a connection between a liquid feed pipe (20) and a coater (10). Swirling motion is imparted to coating liquid discharged from a pump (23) and then a flow velocity of the coating liquid is immediately increased to a level as high as 200 cm/s or more, the liquid then being fed into a pocket (12) of the coater (10) within 0.1 second or less. This permits shearing to act on the coating liquid, to thereby effectively prevent a variation in viscosity of the coating liquid and flocculation thereof, so that the coated film (7) may be improved in surface properties.
