Claims
- 1. An apparatus for fitting a covering material over a supporting insert, said apparatus comprising:
- a stuffing bracket for stuffing the supporting insert into the covering material;
- a material holding assembly comprising a plurality of blades upon which said covering material is placed;
- first means for moving said blades back and forth along a first axis;
- second means for moving said blades back and forth along a second axis perpendicular to said first axis;
- said stuffing bracket and said material holding assembly being movable with respect to each other from a spaced apart position to an insert position where said covering material is fitted over said supporting insert;
- means for selectively moving said stuffing bracket and said holding assembly between said spaced apart position and said insert position;
- a bench on which said stuffing bracket and said holding assembly are mounted; and
- a pivoting arm interconnecting said holding assembly and said bench and operable to permit said holding assembly to be pivoted from an installing position that allows a worker to install said covering material to said holding assembly to a stuffing position for stuffing said stuffing insert into said cover by said stuffing bracket.
- 2. The apparatus of claim 1 wherein each of said blades includes a tip, said tip further including at least one rolling body rotatably attached to said tip, said covering material being passable along said at least one rolling body.
- 3. The apparatus of claim 1 wherein said blades having a low friction surface.
- 4. The apparatus of claim 3 wherein said material is a polymerized material.
- 5. The apparatus of claim 4 wherein said polymerized material is polyethylene.
- 6. The apparatus of claim 3 wherein said material is a metal.
- 7. The apparatus of claim 6 wherein said metal is aluminum.
- 8. The apparatus of claim 1 wherein each of said blades of said holding assembly includes a driver for moving said blades to expand said covering material positioned thereon.
- 9. The apparatus of claim 8 wherein each said driver includes means for limiting the movement of said blade associated therewith whereby the movement of said blade is limited to the maximum size to which said covering material may be expanded.
- 10. The apparatus of claim 1 wherein said first means for moving comprises a driver.
- 11. The apparatus of claim 10 wherein said driver is a pneumatic driver.
- 12. The apparatus of claim 11 wherein said first means for moving further comprises an electronic control system.
- 13. The apparatus of claim 10 and including means for selectively positioning said stuffing bracket and its associated insert and said material holding assembly at selected positions between said first position and said second position.
- 14. The apparatus of claim 13 wherein said means for selectively positioning said stuffing bracket and said material holding assembly includes a programmer for selectively positioning said stuffing bracket at predetermined positions.
- 15. The apparatus of claim 13 wherein said means for selectively positioning said stuffing bracket and said material holding assembly includes a manually-operable control knob and a control board, said control knob being movable upon said control board to select positions for said stuffing bracket and said material holding assembly.
- 16. The apparatus of claim 13 including a pre-set timer that provides for a pre-set increment of stop time before the relative motion of the stuffing bracket and said material holding assembly restarts.
- 17. The apparatus of claim 1 wherein said stuffing bracket further includes a ledge upon which an end of said insert may be rested.
- 18. An apparatus for fitting a covering material over a supporting insert, said apparatus comprising:
- a stuffing bracket for stuffing the supporting insert into the covering material;
- a material holding assembly comprising a plurality of blades upon which said covering material is placed;
- a first means for moving said blades back and forth along a first axis;
- a second means for moving said blades back and forth along a second axis perpendicular to said first axis;
- said stuffing bracket and said material holding assembly being movable with respect to each other from a spaced apart position to an insert position where said covering material is fitted over said supporting insert;
- means for selectively moving said stuffing bracket and said holding assembly between said spaced apart position and said insert position; and
- a pivoting arm connected to said holding assembly and operable to permit said holding assembly to be pivoted from an installing position that allows a worker to install said covering material to said holding assembly to a stuffing position for stuffing said stuffing insert into said cover by said stuffing bracket.
- 19. An apparatus for fitting a covering material over a supporting insert, said apparatus comprising:
- a stuffing bracket for stuffing the supporting insert into the covering material;
- a material holding assembly comprising a plurality of blades upon which said covering material is placed;
- means for moving said blades back and forth along an axis;
- said stuffing bracket and said material holding assembly being movable with respect to each other from a spaced apart position to an insert position where said covering material is fitted over said supporting insert;
- means for selectively moving said stuffing bracket and said holding assembly between said spaced apart position and said insert position;
- a bench on which said stuffing bracket and said holding assembly are mounted; and
- a pivoting arm interconnecting said holding assembly and said bench and operable to permit said holding assembly to be pivoted from an installing position that allows a worker to install said covering material to said holding assembly to a stuffing position for stuffing said stuffing insert into said cover by said stuffing bracket.
