Abstract
A method and an apparatus for manufacturing Z-folded cell stacks. First and second cell components are alternately stacked while a separator web is inserted in between in a Z-shaped or meandering manner and is subsequently wrapped one more time around the cell stack thus obtained. Wrapping is performed at least in part in parallel with a previously obtained cell stack while stacking of the next cell stack is performed. A supply of the separator web required for wrapping is provided in a separator buffer storage, is cut off and held at the trailing end, in the conveying direction, with a separating gripper and is fed with the separating gripper during wrapping.
