Abstract

A method of cutting a window covering having a longitudinal axis and a second axis substantially perpendicular to said longitudinal axis to a specified length includes providing a cutting apparatus including a base having a cutting surface. The cutting apparatus has a cutting blade slidably mounted thereon for sliding along a movement axis toward and away from the cutting surface. The window covering is then positioned atop the cutting surface of the base and the cutting blade is moved along the movement axis and toward the cutting surface to cut the window covering to the specified length. The movement axis has a first component extending substantially perpendicular to the longitudinal axis of the window covering and substantially perpendicular to the second axis of the window covering and a second component extending substantially parallel to the second axis of the window covering.

Claims

1. A method of cutting a window covering to a specified length, said window covering including a headrail, a bottom rail and window covering material extending between said headrail and said bottom rail, said window covering having a longitudinal axis and a second axis substantially perpendicular to said longitudinal axis, the method comprising:

providing a cutting apparatus including a base having a cutting surface, said cutting apparatus having a cutting blade slidably mounted thereon for sliding along a movement axis toward and away from said cutting surface;

positioning said window covering atop said cutting surface of said base so that said headrail, said bottom rail and said window covering material are arranged side-by-side atop said cutting surface; and

moving said cutting blade along said movement axis and toward said cutting surface to cut said window covering to said specified length, said movement axis including a first component extending substantially perpendicular to the longitudinal axis of said window covering and substantially perpendicular to the second axis of said window covering and a second component extending substantially parallel to the second axis of said window covering, wherein said window covering is positioned atop said cutting surface during the positioning step so that said cutting blade simultaneously cuts through said headrail, said bottom rail and said window covering material during the moving step.

2. The method as claimed in claim 1, further comprising securing said window covering atop said cutting surface prior to moving said cutting blade.

3. The method as claimed in claim 2, wherein said securing step includes clamping said window covering atop said cutting surface.

4. The method as claimed in claim 1, further comprising measuring said window covering before the moving said cutting blade step so as to define an end portion of said window covering to be cut, said moving the cutting blade step including the step of cutting said end portion.

5. The method as claimed in claim 4, further comprising providing a measuring assembly adjacent said cutting blade before the measuring step.

6. The method as claimed in claim 5, wherein said measuring assembly includes a stop block, said measuring step including the step of abutting an end portion of said window covering against said stop block.

7. The method as claimed in claim 6, further comprising moving said stop block away from said cutting blade during said moving said cutting blade step so as to allow the end portion of said window covering to pivot away from said cutting blade.

8. The method as claimed in claim 7, wherein said cutting apparatus includes a driver mechanically interconnected with said cutting blade and said stop block for imparting motion to said cutting blade and said stop block during operation of said driver.

9. The method as claimed in claim 7, wherein the moving said stop block away step includes disengaging said stop block from the end portion of said window covering.

10. The method as claimed in claim 1, wherein the positioning said window covering step includes guiding said window covering over said cutting surface and toward said cutting blade so that said cutting blade overlies an end portion of said window covering.

11. The method as claimed in claim 1, wherein said cutting blade includes a cuffing edge at a lower end thereof.

12. The method as claimed in claim 1, further comprising maintaining the cutting edge of said cuffing blade parallel to the cutting surface of said base during the moving said cutting blade step.

13. A method of cutting a window covering to a specified length, said window covering including a headrail, a bottom rail and window covering material extending between said headrail and said bottom rail, said window covering having a longitudinal axis and a second axis substantially perpendicular to said longitudinal axis, the method comprising:

providing a cutting apparatus including a base having a cutting surface, said cutting apparatus including a cutting blade having a cutting edge, said cutting blade being slidably mounted on said cutting apparatus for sliding along a movement axis toward and away from said cutting surface;

positioning said window covering atop said cutting surface of said base so that said headrail, said bottom rail and said window covering material are arranged side-by-side atop said cutting surface;

moving said cutting blade along said movement axis and toward said cutting surface to cut said window covering to said specified length, said movement axis including a first component extending substantially perpendicular to the longitudinal axis of said window covering and substantially perpendicular to the second axis of said window covering and a second component extending substantially parallel to the second axis of said window covering, wherein said cutting blade simultaneously cuts through said headrail, said bottom rail and said window covering material during the moving step; and

maintaining the cutting edge of said cutting blade parallel to said cutting surface.

14. A method of cutting a window covering including a headrail, a bottom rail and window covering material extending between said headrail and said bottom rail, the method comprising:

providing a cutting apparatus including a base having a cutting surface, said cutting apparatus including a cutting blade slidably mounted thereon for sliding along a movement axis toward and away from said cutting surface;

positioning said window covering atop said cutting surface so that said headrail, said bottom rail and said window covering material are arranged side-by-side atop said cutting surface;

moving said cutting blade along said movement axis and toward said cutting surface to cut said window covering to a specified length, said movement axis including a first component extending substantially perpendicular to said cutting surface and a second component extending substantially parallel to said cutting surface, wherein said window covering is positioned atop said cutting surface during the positioning step so that said cutting blade simultaneously cuts through said headrail, said bottom rail and said window covering material during the moving step.

15. The method as claimed in claim 14, wherein said cutting blade has a cutting edge at a lower end thereof.

16. The method as claimed in claim 15, further comprising maintaining the cutting edge of said cutting blade parallel to said cutting surface during said moving step.

17. The method as claimed in claim 14, wherein said cutting apparatus includes at least one guide track extending in a direction parallel to the movement axis of said cutting blade, said cutting blade being slidably mounted in said at least one guide track.
