Claim:
1. A stacked cell manufacturing method comprising the steps of: executing zigzag-folding of a band-like separator on a table by a zigzag-folding mechanism; alternately feeding a positive-plate and a negative-plate onto the separator as folded back by a positive-plate feeding-mechanism, and a negative-plate feeding-mechanism every time the separator is folded back by the zigzag-folding; and alternately stacking the positive-plate and the negative-plate on the table with the separator interposed therebetween, wherein a positive-plate transfer head as a part of the positive-plate feeding-mechanism, and a negative-plate transfer head as a part of the negative-plate feeding-mechanism are set so as to alternately undergo a linearly reciprocating transfer between a position for an electrode-plate stacking work and standby positions of the positive-plate transfer head and the negative-plate transfer head feeding an electrode-plate in a horizontal direction at least on the table by respective transfer mechanisms in the step of stacking, a direction of a horizontal and reciprocating transfer between the position for the electrode-plate stacking work and the standby positions of the positive-plate transfer head and the negative-plate transfer head feeding the electrode-plate on the table made by the positive-plate transfer head and the negative-plate transfer head is set to coincide with a folding-back direction of the zigzag-folding of the separator, and a force caused by the horizontal and reciprocating transfer between the position for the electrode-plate stacking work and the standby positions of the positive-plate transfer head and the negative-plate transfer head feeding the electrode-plate alternately made by each of these transfer heads is imparted to the separator guided onto the table by the positive-plate transfer head and the negative-plate transfer head, respectively, thereby executing the zigzag-folding while the separator is drawn onto the table, set to hold down to the table by a zigzag-folding clamp and securing a valley-folding of the zigzag-folding of the separator, and the positive-plate transfer head and the negative-plate transfer head alternately feed the positive-plate and the negative-plate, respectively, onto the table, while executing the zigzag-folding of the separator.
