Abstract: A long length of large plastic sheet tubing is stored in a cardboard storage cartridge having a hollow, box-like, flattened housing with a large circular opening in the top wall and a large circular opening in the bottom wall aligned with the first opening. A hollow center core is integral with the top wall and is present within the cartridge, and it is of generally cylindrical form. Both the top and bottom walls of the cartridge are of generally square form, and the top wall has downturned side flanges that have a height slightly greater than the height of the hollow center core. A long length of large plastic sheet tubing is loaded into the cartridge when the bottom wall is opened and the cartridge is inverted, where the plastic sheet tubing is folded lengthwise or compressed into the area bounded by the hollow center core and the side flanges and the top and bottom walls of the cartridge housing. Means are provided for sealing the bottom wall to the cartridge to confine the plastic sheet tubing therein.

Abstract: Apparatus is mounted on the rear of a riding lawn mower for utilizing a large supply of large size plastic sheet tubing to form plastic bags as needed for receiving the grass cuttings being discharged from the lawn mower, so that the mower operator need not leave his seat on the lawn mower in order to seal the plastic bag after it is full of cuttings, and to discharge the bag away from the lawn mower. This apparatus is vertically mounted. The grass cuttings are blown to the top of the apparatus into a first air-release funnel. Beneath this funnel is a supply of large plastic sheet tubing folded lengthwise into an annular cartridge. A throttle section is positioned beneath the cartridge for collapsing the sheet tubing into a rope-like formation. Then a pair of vertically-spaced sealing tape dispensers serve to seal the rope-like formation at two locations. Then a cutter severs the plastic to complete sealing the top of a filled bag and for sealing the bottom of the next plastic bag to be filled.
