1. An apparatus for manufacturing a bagged electrode with a first electrode of a battery interposed between a pair of separators, the apparatus comprising:
a conveying unit configured to convey the first electrode in a manner interposed between a pair of long separator materials unwound from a pair of rolls;
a first bonding unit configured to bond the pair of long separator materials outside the first electrode along a conveyance direction without stopping conveyance of the first electrode and the pair of long separator materials;
a second bonding unit configured to bond the pair of long separator materials outside the first electrode along a direction intersecting the conveyance direction without stopping conveyance of the first electrode and the pair of long separator materials; and
a separating unit configured to cut the pair of long separator materials along the direction intersecting the conveyance direction to cut off the bagged electrode without stopping conveyance of the first electrode and the pair of long separator materials,
wherein
the second bonding unit includes a pair of rotators including thereon a pair of tooth members that engage each other and configured to rotate with conveyance of the first electrode and the pair of long separator materials, the pair of rotators interposing and crimping the pair of long separator materials therebetween to bond the pair of separator materials,
each of the pair of tooth members of the second bonding unit is provided in two rows of teeth in the direction intersecting the conveyance direction, and the pair of tooth members are provided on respective peripheral surfaces of the pair of rotators, and
a cutting blade is arranged between the two rows of teeth on one of the rotators of the second bonding unit.
