ABSTRACT:
An improved apparatus and method are disclosed for winding into a spiral roll the positive (186) and negative (241) plates of small cylindrical batteries. The originally flat positive and negative pasted plates are conveyed through stations at which they are automatically wrapped with strips of separator material (24, 84). Then the wrapped plates are stacked in a staggered pattern and conveyed to a winding station (78). There the stack of plates is wound into a spiral roll around an arbor (332) surrounded by three driven rolls (322, 324, 326) over which a guide belt (366) is run. As the spiral roll is formed, the driven rolls move radially outwardly from the arbor under the control of a mechanism (362, 402-430) which ensures that the final roll diameter will be within desired tolerances. The outermost layer of plate wrapping material is thermally sealed (104, 105) to the roll to prevent its unwinding; and then a further mechanism (432-478) automatically ejects the completed roll from the arbor.
