Window covering sizing method and apparatus
View Patent ↗An apparatus for cutting a window covering and methods of cutting a window covering are provided. A method of operating a window covering cutting machine comprises a) packaging a window covering comprising components in a package such that first ends of the components extend beyond a first end of the package and second ends of the components extend beyond a second end of the package; b) automatically moving the package and components in a first direction of travel against a first squaring surface such that the first ends of the components are in a common plane; c) cutting the first ends of the components; d) automatically moving the package and components in a second direction of travel against a second squaring surface such that the second ends of the components are in a common plane; and e) cutting the second ends of the components.
1. A method of operating a window covering cutting machine comprising:
a) packaging a window covering comprising components in a package such that first ends of the components extend beyond a first end of the package and second ends of the components extend beyond a second end of the package;
b) automatically moving the package and components in a first direction of travel against a first squaring surface such that the first ends of the components are in a common plane, the first squaring surface being the face of a first saw blade;
c) cutting the first ends of the components;
d) automatically moving the package and components in a second direction of travel against a second squaring surface such that the second ends of the components are in a common plane; and
e) cutting the second ends of the components.
2. The method of claim 1 further comprising, prior to step b), automatically moving the package and components against a squaring plate such that the second ends of the components are in a common plane.
3. The method of claim 1 wherein the first squaring surface is arranged such that it is perpendicular to the first direction of travel.
4. The method of claim 1 further comprising moving the first squaring surface between a first position where the first squaring surface intersects the first direction of travel and a second position where the first squaring surface does not intersect the first direction of travel.
5. The method of claim 1 wherein the second squaring surface is arranged such that it is perpendicular to the second direction of travel.
6. The method of claim 5 wherein the second squaring surface is the face of a second saw blade.
7. The method of claim 1 wherein the second squaring surface is the face of a second saw blade.
8. The method of claim 1 further comprising moving the second squaring surface between a first position where the second squaring surface intersects the second direction of travel and a second position where the second squaring surface does not intersect the second direction of travel.
9. The method of claim 8 wherein the second squaring surface is the face of a second saw blade.
10. The method of claim 1 further comprising retracting the first squaring surface and moving the window covering in the first direction of travel in front of the first saw.
11. The method of claim 10 further comprising rotating the first saw at high speed and moving the first saw into engagement with the components.
12. The method of claim 11 further comprising extending a clamp to hold the window covering when the first saw is moved into engagement with the components.
13. The method of claim 12 further comprising contacting the components directly with the clamp.
14. The method of claim 1 further comprising retracting the second squaring surface and moving the window covering in the second direction of travel in front of a second saw.
15. The method of claim 14 further comprising rotating the second saw at high speed and moving the second saw into engagement with the components.
