Abstract

A finishing apparatus for ductwork having a duct body with at least one open end. The finishing apparatus includes an operation platform for selectively supporting the ductwork and a first wrapping mechanism integrated with the operation platform, the first wrapping mechanism including a first dispenser for dispensing a first film. The finishing apparatus further includes a first cutting mechanism integrated with the first wrapping mechanism. In operation, the first wrapping mechanism selectively dispenses the first film adjacent to and against the open end of the ductwork as the ductwork is moved a predetermined distance down the operation platform. The first cutting mechanism selectively cutting the first film after the ductwork has moved the predetermined distance down the operation platform.

Claims (39)

1. A finishing apparatus for ductwork, said ductwork defining a duct body having at least one open end, said finishing apparatus comprising:

an operation platform, said operation platform selectively supporting said ductwork;

a first wrapping mechanism integrated with said operation platform, said first wrapping mechanism including a first dispenser for dispensing a first film therefrom;

a first cutting mechanism, said cutting mechanism being integrated with said first wrapping mechanism; and

wherein said first wrapping mechanism selectively dispenses said first film adjacent to and against said open end of said ductwork as said ductwork is moved a predetermined distance down said operation platform, said first cutting mechanism selectively cutting said first film after said ductwork has moved said predetermined distance down said operation platform.

2. The finishing apparatus according to claim 1 , wherein:

said operation platform includes a plurality of rollers; and

said first wrapping mechanism is pivotally disposed adjacent to said rollers so as to be substantially beneath said ductwork when said ductwork is moving down said operation platform.

3. The finishing apparatus according to claim 1 , wherein:

said first wrapping mechanism includes a first vacuum assembly, said first vacuum assembly being selectively operable to cause a vacuum to be applied to said first film.

4. The finishing apparatus according to claim 1 , wherein:

said first wrapping mechanism includes a first cutting knife, said first cutting knife being selectively moved between a first position where said first film cannot be cut, and a second position where said first film can be cut.

5. The finishing apparatus according to claim 4 , wherein:

said first cutting knife defines a wavy blade edge.

6. The finishing apparatus according to claim 1 , further comprising:

a frame assembly disposed above said operation platform, said frame assembly supporting a second wrapping mechanism and a second dispenser for dispensing a second film therefrom; and

wherein said second wrapping mechanism further includes a second cutting mechanism for selectively cutting said second film.

7. The finishing apparatus according to claim 6 , wherein:

said second wrapping mechanism includes a second vacuum assembly, said second vacuum assembly being selectively operable to cause a vacuum to be applied to said second film.

8. A method of sealing a duct body having at least one open end, said method comprising the steps of:

positioning said duct body on an operation platform;

integrating a first wrapping mechanism with said operation platform, said first wrapping mechanism including a first dispenser for dispensing a first film therefrom;

arranging a first cutting mechanism adjacent said first wrapping mechanism;

moving said duct body to a predetermined position on said operation platform, said first wrapping mechanism selectively dispensing said first film adjacent to and against said open end of said duct body; and

engaging said first cutting mechanism to cut said first film after said duct body has moved to said predetermined position.

9. The method of sealing a duct body according to claim 8 , said method further comprising the steps of:

forming said operation platform from a plurality of rollers; and

pivotally disposing said first wrapping mechanism adjacent to said rollers so as to be substantially beneath said ductwork when said ductwork is moving down said operation platform.

10. The method of sealing a duct body according to claim 8 , said method further comprising the steps of:

arranging a first vacuum assembly adjacent to said first wrapping mechanism, said first vacuum assembly being selectively operable to cause a vacuum to be applied to said first film.

11. The method of sealing a duct body according to claim 8 , said method further comprising the steps of:

integrating a first cutting knife with said first wrapping mechanism, said first cutting knife being movable between a first position where said first film cannot be cut, and a second position where said first film can be cut.

12. The method of sealing a duct body according to claim 11 , said method further comprising the steps of:

forming said first cutting knife to have a wavy blade edge.

13. The method of sealing a duct body according to claim 8 , said method further comprising the steps of:

disposing a frame assembly over said operation platform, said frame assembly supporting a second wrapping mechanism and a second dispenser for selectively dispensing a second film therefrom; and

integrating a second cutting knife with said second wrapping mechanism.

14. The method of sealing a duct body according to claim 8 , said method further comprising the steps of:

integrating a second vacuum assembly with said second wrapping assembly, said second vacuum assembly being selectively operable to cause a vacuum to be applied to said second film.
