Beschreibung
Zusammenfassung:	An apparatus for merging webs for the production of an electrode assembly for a secondary battery includes first and second webs of base material wound on a first spool and a second spool, respectively. The apparatus also includes first and second rotating assemblies configured to move the first and second webs of base material along a first web merge path and a second web merge path, respectively. The first and second rotating assemblies are configured to control a tension of the respective web of base material in a down web direction along a portion of the respective web merge path located between the respective spool and rotating assembly. The apparatus also includes a receiving member configured to receive the first and second webs of base material at first and second web merge locations, respectively, such that the second web of base material overlays the first web of base material.
