Device for Z-Shaped Folding of a Separator and Method for Producing an Electrode Separator Arrangement

A device (10) for z-shaped folding of a ribbon-like separator (1) extending in a longitudinal direction (x) for an electrode separator arrangement of an individual battery cell, comprising:

• two stamps (3) for clamping the ribbon-like separator (1) in the longitudinal direction (x);
• brackets (5) disposed between the two stamps (3) which have a same spacing in relation to each other in the longitudinal direction (x) and which each have a respective strut (6) in a transverse direction (y) running transversely to the longitudinal direction (x);
• and
• rails (4) moveable in a vertical direction (z) transversely to the longitudinal direction (x) and transversely to the transverse direction (y);
• wherein, when seen in the longitudinal direction (x), the struts (6) are disposed alternately above and below a clamping position of the ribbon-like separator (1) in the vertical direction (z);
• wherein the brackets (5) are received shiftably in the longitudinal direction (x) on the rails (4) running in the longitudinal direction (x);
• wherein the struts (6) are formed to be heatable and/or wherein the device (10) further comprises a cutting device for severing the ribbon-like separator (1) in a region of the struts (6) in a position of the two stamps (3) moved as close to each other as possible.
