Method using blades and fins to form sheet material into a flower pot cover having inward fins

A method of forming a flower pot or flower pot cover having a plurality of radially inwardly extending fins, the steps of the method comprising:

• providing a male tool having a plurality of radially extending first plates and a plurality of radially extending second plates, each of the first plates corresponding with one of the second plates to define a fin forming pair of plates, the plates movable between an open position wherein each of the first plates is spaced a distance from the corresponding second plate to define a fin-forming space therebetween and a closed position wherein each of the first plates and the corresponding second plate are substantially together;
• providing a blade assembly having a plurality of blades adapted for movement between a storage position wherein the blades are spaced a distance from the male tool and a fin-forming position wherein each blade is disposed in a corresponding one of the fin-forming spaces;
• placing a sheet of material between the male tool and the blade assembly with the blade assembly in the storage position;
• moving each of the blades radially inwardly into the fin-forming position with the plates of the male tool in the open position so as to force a portion of the sheet of material radially inwardly into each of the fin-forming spaces;
• moving the blade assembly to the storage position to withdraw the blades from the fin-forming spaces;
• and
• moving the plates of the male tool to the closed position after the blades have been withdrawn from the fin-forming space to form the portions of the sheet of material disposed in the fin-forming spaces into radially inwardly extending fins.
