PROBLEM TO BE SOLVED: To improve an adhesive property of an electrode active material layer and a current collector by providing a means for preventing acid in paint from sticking to the other surface of a paint unapplied current collector through sublimating or evaporating at drying time of a paint film layer of electrode paint formed on one surface of an electrode current collector. SOLUTION: A paint film layer 5 applied to one surface 2a of an electrode current collector continuously carried from a delivery roller by the use of an applying device 10, is dried by a hot blast in a dryer 20 of the next process. At that time, since the other surface 2b (the reverse) of the electrode current collector moves by sliding on a guide plate 7 fixed in the dryer 20, the hot blast containing an acid evaporated or sublimated from the paint film layer 5 formed on one surface 2a of the electrode current collector does not make contact with it. That is, the guide plate 7 makes close contact with the other surface 2b of the electrode current collector until the drying of the paint film layer 5 so as to function as an acid sticking preventive sheet. As the guide plate 7, a stainless plate is suitable. |
