<P>PROBLEM TO BE SOLVED: To manufacture a battery electrode plate without producing an excess electrode material portion which lowers the safety of an electrode plate and without disposing of the excess portion. <P>SOLUTION: A removal mechanism 20 comprises a bobbin holder 26 for holding a thread 25, a tensile force control mechanism 28 for controlling the tensile force of the thread 25, an intermediate holder 27, and a recovery unit 29 for recovering a removed excess portion in the width direction, 3a. The thread 25 of the removal mechanism 20 abuts on the side of a collector 2 at an angle of less than 90 degrees with respect to the plane of the collector 2, and its component force in the horizontal direction of compressive force toward the inside is set to a value greater than 0.1 [kgf] but not large enough to cause wrinkles or breakage in an electrode plate 21 depending on a material of the collector. The excess portion in the width direction, 3a, is thereby peeled off and then recovered by the recovery unit 29 for reuse. The excess portion in the width direction, 3a, of an electrode plate 1 is removed and recovered through the removal mechanism 20, whereby an electrode plate 21 is obtained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
