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

A roll press apparatus forms a compressed strip-shaped electrode plate by roll-pressing a strip-shaped electrode plate including an active material portion and an active material absent portion and including a tensile-force-ratio adjustment mechanism adjusting a tensile force ratio of an upstream active material absent portion tensile force applied to an upstream side and a downstream active material absent portion tensile force applied to a downstream side of an inter-roll active material absent portion held in a non-compressed state between a pair of press rolls in an active material absent portion of the strip-shaped electrode plate.
