Abstract
The present disclosure provides an efficient technique for manufacturing laminates for secondary batteries each having a separator and electrodes, which in turn enables continuous and efficient manufacturing of laminate type secondary batteries. An apparatus for manufacturing a laminate for a secondary battery of the present disclosure includes an electrode roll of a long electrode web rolled into a roll shape; a separator roll of a long separator web rolled into a roll shape; a lamination mechanism for laminating the separator web fed out from the separator roll and the electrode web fed out from the electrode roll while causing the separator web to be bent or curled to form a protruding portion extending across an entire width of the separator web so that the protruding portion is disposed so as to oppose to the electrode web; and a cutting mechanism for cutting at least the electrode web portion in a laminated article of the separator web and the electrode web at a position where the protruding portion has been provided.
