Abstract
Sheaths for covering battery electrodes are produced by introducing inner and outer layers of sheath material onto a plurality of adjacent mandrels. As the layers pass along connector sections of the mandrels, they are connected together to form interconnected tubes. The connector sections have an elongate cross-sectional configuration to facilitate such connection. Thereafter, the layers pass along reshaping sections of the mandrels which have a cross-sectional configuration that is different from that of the connector sections and which corresponds to the desired final shape of the tubes.
