Patent ID: 8617257

Claim:
A device for stacking a successive tape-shaped separator and a sheet electrode, the device sequentially stacking the separator and the sheet electrode while folding the successive separator to form a stacked body, and the device comprising: a stacking stage which holds a leading end of the tape shaped separator and on which the sheet electrode and the separator are sequentially stacked; separator reciprocating means for reciprocating the tape-shaped separator above the stacking stage with the stacking stage being as a center; and a folding guide member which comes close or moves apart relative to the stacking stage along is perpendicular direction to a moving direction of the separator so as to cover sides of both ends of the stacked sheet electrode, the sides being in the moving direction of the separator, and which guides folding of the separator accompanied by a reciprocal movement of the separator at both ends of the sheet electrode, wherein the separator is folded by the folding guide member which is configured to cover and protect an end portion of the sheet electrode when the separator is folded.
