Abstract: A cushioning conversion system (10) and method wherein a stock roll storage rack (14) is used to support at least one and preferably a plurality of stock rolls (21) at the same level as the stock roll holder (19) of a cushioning conversion machine (12). The stock roll storage rack (14), which stores the stock rolls (21) in a substantially horizontal array, enables an operator to easily load the machine (12) without having to lift a stock roll (21) to the height of the stock roll holder (19). Also, plural stock roll storage racks (14) can be used interchangeably, whereby one can be loaded with stock rolls (21) by an attendant while the other is used to load stock rolls (21) onto the cushioning conversion machine (12). The stock roll storage rack (14) includes a stand (70) and a stock roll storage shelf (72) vertically adjustable on the stand (70) to match the height of the storage shelf (72) to the height of a stock roll holder (19) on the conversion machine (12).
