ROLL PRESS APPARATUS AND MANUFACTURING METHOD FOR COMPRESSED STRIP-SHAPED ELECTRODE PLATE

A roll press apparatus (100) forms a compressed strip-shaped electrode plate (1) by roll-pressing a strip-shaped electrode plate (1Z) including an active material portion (11Z) and an active material absent portion (12Z) and including a tensile-force-ratio adjustment mechanism (140) adjusting a tensile force ratio (τd / τu) of an upstream active material absent portion tensile force (τu) applied to an upstream side (EUH) and a downstream active material absent portion tensile force (τd) applied to a downstream side (EDH) of an inter-roll active material absent portion (12Zb) held in a non-compressed state between a pair of press rolls (110, 120) in an active material absent portion (12Z) of the strip-shaped electrode plate (1Z).
