Claims12
A method for forming a sheet of material into a flower pot or flower pot cover, the steps of the method comprising:
- providing a male die having a male die surface;
- providing a female die having an opening formed through a portion thereof and having a plurality of lower fingers, the opening defining a female die surface and the lower fingers being adapted to extend inwardly form the perimeter of the opening generally toward the center of the opening;
- placing a sheet of material having an upper surface and a lower surface between the male die and the female die with at least a portion of the sheet of material disposed over the opening of the female die;
- moving an upper ring having a plurality of upper fingers into a pleat-controlling position wherein each upper finger engages the upper surface of the sheet of material between two of the lower fingers;
- and
- moving the male die through the upper ring and into a forming position wherein the male die is disposed in the opening of the female die with a least a portion of the sheet of material being disposed generally between the male die surface and the female die surface;
- wherein each lower finger engages the lower surface of the sheet of material between two corresponding upper fingers, and cooperates with the two corresponding upper fingers to form a pleat in the sheet of material between the lower finger and each of the corresponding upper fingers as the male die and the female die form the sheet of material into a flower pot or flower pot cover.
