<P>PROBLEM TO BE SOLVED: To solve problems seen in a manufacturing device of an electrode group for a nonaqueous secondary battery that peeling-off or missing of an electrode mixture layer occurs due to a force of the electrode mixture layer of an electrode plate acting in the direction of being peeled off from a current collector, since a movable nip roller and a fixed nip roller are constituted at a nip roller part in which a positive electrode plate and a negative electrode plate are retained so as not to be fallen off by tension generated in a transport path during the time until being wound around a winding core, and prevented from slipping off by strong pressing, however, at this time, the electrode mixture layer of the electrode plate is deformed into a shape of a pressing roller along the shape of an elastic body of a driving roller. <P>SOLUTION: In the manufacturing device of the electrode group for the nonaqueous secondary battery, the nip roller part 5 is equipped, and the positive electrode plate 8 and the negative electrode plate 9 come into line contact with each other in a state not being deformed at the nip roller part 5. <P>COPYRIGHT: (C)2009,JPO&INPIT |
