Production apparatus of multilayer coating film

摘要

The coating construction has flexibility corresponding to the number of layers of multiple coating layers, by which a multilayer coating film can be produced with small film thickness without adherence of dust to a film surface, a drying fault such as unevenness induced by drying-wind on the film surface, or a coating fault such as a level variation and a streak. The multilayer coating film has a coating surface state of high quality with coating thickness deviation of 3% or less. A coating device is constructed in which at least a feed roller, a coater and a dryer are integrally incorporated in a casing, and the coating device is given a function as an independent device, whereby the production apparatus of the multilayer coating film can be constructed by only appropriately placing as many coating devices as the number corresponding to the number of layers of the multiple coating layers formed on a web between a delivery device and a winder.
