  • Apparatus for manufacturing spiral electrode assembly
    Patent number: 6692542
    Abstract: A separator is inserted into a slit formed in a winding core. A negative electrode plate made of thin metallic foil is fed toward the winding core as being held around the circumferential surface of a tape suction drum that is rotatably supported. The tape suction drum and the winding core are brought in mutual contact under pressure with their respective axes in parallel, and the winding core is driven to rotate, so that the tape suction drum is synchronously rotated with the winding core, by means of the frictional force acting between them, whereby the negative electrode plate held on the tape suction drum is wound onto the winding core together with the separator.
