ABSTRACT:
A coating die is disclosed, in which a slit-like spacing 29 is formed between a pair of die elements 25, 27 arranged in opposed relation to each other. A band-shaped electrode sheet 23 is movable along the length of the spacing 29. The sides of the slit-like spacing along the width of the electrode sheet 23 are enclosed. An electrode piling agent is supplied from an external source into the die element pair 25, 27 through supply flow paths 47, 49. Discharge ports 47a, 49a of the supply flow paths 47, 49 are open to the slit-like spacing 29. The portion of the spacing 29 downstream of the discharge ports 47a, 49a in the direction of movement of the electrode sheet 23 has a thickness equivalent to the thickness of the electrode sheet 23 plus the thickness of the electrode piling agent coated on the two sides of the electrode sheet 23. The portion of the spacing 29 upstream of the discharge ports 47a, 49a has a thickness substantially equal to the thickness of the electrode sheet 23. The job of coating the electrode piling agent on the two sides of the electrode sheet can thus be performed with high accuracy.
