PROBLEM TO BE SOLVED: To improve the uniformity of dryness of a coating film formed in a web.SOLUTION: A dryer 100 has: hot air supply means 110; and hot air jet means 120 which jets hot air supplied from the hot air supply means 110 to a surface (a rear surface) of a web 10 which is opposite to a coating film formation surface (a front surface). The hot air jet means 120 has hot air spray width restriction means 121. The hot air spray width restriction means 121 restricts a hot air spray range so that a width of the hot air sprayed to the rear surface of the web becomes narrower than a width of the web. The structure prevents the hot air sprayed to the rear surface of the web from coming around to the surface from the outer side of the web.SELECTED DRAWING: Figure 1 |
