a method and apparatus is disclosed for simultaneously creating a pair of stacks of nested sinuous spring strips . this apparatus includes first and second generally circular forming drums onto which a feeder mechanism is operable to sequentially and alternately pass each of the spring strips from over a forming mandrel onto the top surface of the first and second generally circular forming drums . a first stripper mechanism is then operable to strip a first one of the strips onto a first stacking drum and for stripping a second following one of the strips onto a second stacking drum . a second stripper mechanism is then operable to strip those stacks from the stacking drums onto a pair of discharge chutes .
