An apparatus for folding agricultural storage bags (20) includes a frame (22) having an annular pad (70) mounted about the lateral periphery thereof. Pivotally mounted within and extending outwardly from the frame above the annular pad (70) are a plurality of upper arms (110). A plurality of lower arms (126) are similarly mounted below the annular pad (70) and are positioned between the upper arms (110). Mounted within the frame (22) above the upper arms (110) is a platform (26) for supporting a quantity of flexible tubular material. Mounted to the frame above the platform (26) is an advancing mechanism (50). The upper and lower arms (110 and 126) are actuated alternately to form the length of flexible tubular material into a plurality of folds each extending parallel to the annular pad (70).
