Abstract
A process for merging webs for the production of an electrode assembly for a secondary battery, the process comprising: moving a first web comprising a population of first components for electrode sub-units, the first components delineated by corresponding weakened patterns, and a population of first conveying features. Moving a second web comprising a population of second components for the electrode sub-units, the second components delineated by corresponding weakened patterns, and a population of second conveying features. Conveying a receiving member, the receiving member comprising a plurality of projections. Receiving the first web on the receiving member. Overlaying, the second web on the first web such that the first components are aligned with the second components and the conveying features of the second web are engaged by the plurality of projections on the receiving member. The second web merge location being spaced from the first web merge location.
