Abstract

A method of trimming blinds is disclosed in which at least one spacer is attached to a blind to space the headrail, bottomrail, and window covering between the headrail and bottomrail in relative positions that correspond to openings in a cutting device. A portion of the blind that is desired to be cut is then moved into those openings and cut away.

Claims

1. A method of cutting a blind comprising:

providing a blind of the type having a headrail, a bottomrail and window covering material between the headrail and the bottomrail;

providing a cutting device having at least three spaced openings, a first opening sized to receive the headrail, a second opening sized to receive the window covering material, and a third opening sized to receive the bottomrail, the openings having a known relative spacing from one another, and being on a common axis;

attaching at least one collar to the blind, the at least one collar spacing the headrail, window covering material and bottomrail at a relative spacing from one another that corresponds to the relative spacing of the first opening, second opening, and third opening in the cutting device;

moving a portion of the blind into the spaced openings in the cutting device, a portion of the headrail being moved into the first opening, a portion of the window covering material being moved into the second opening, and a portion of the bottomrail being moved into the third opening; and

cutting the portion of the blind; and

the at least one collar being comprised of;

a generally rectangular first ring sized to receive the headrail, the first ring having a bottom and a first selected width;

a generally rectangular second ring sized to receive the bottomrail, the second ring having a top and a second selected width; and

a pair of spaced apart side walls extending from the bottom of the first ring to the top of the second ring, the sidewalls, bottom of the first ring, and top of the second ring, defining a cavity sized to receive the window covering material.

2. The method of claim 1 wherein the window covering material is selected from the group consisting of a plurality of slats, pleated material and cellular material.

3. The method of claim 1 wherein the at least one collar is further comprised of at least one partition within the cavity sized to receive the window covering.

4. The method of claim 1, wherein the at least one collar is further comprised of a material selected from the group consisting of plastics, polyvinyl chloride, cardboard, and metal.

5. The method of claim 1 wherein the blind is partially within a box while a portion of the blind is being moved into the spaced opening.

6. The method of claim 1 the method further comprising putting the blind in a package.

7. The method of claim 6, wherein the blind is put in the package after the at least one collar is attached to the blind.

10. The method of claim 1 the method further comprising clamping the window covering material.

8. A method of cutting a blind comprising:

providing a blind of the type having a headrail, a bottomrail and window covering material between the headrail and the bottomrail;

providing a cutting device having at least three spaced openings, a first opening sized to receive the headrail, a second opening sized to receive the window covering material, and a third opening sized to receive the bottomrail, the openings having a known relative spacing from one another, and being on a common axis;

attaching at least one collar to the blind, the at least one collar spacing the headrail, window covering material and bottomrail at a relative spacing from one another that corresponds to the relative spacing of the first opening, second opening, and third opening in the cutting device;

moving a portion of the blind into the spaced openings in the cutting device, a portion of the headrail being moved into the first opening, a portion of the window covering material being moved into the second opening, and a portion of the bottomrail being moved into the third opening; and

cutting the portion of the blind; and

the at least one collar comprised of;

a first half ring sized to receive the headrail, the first half ring having a bottom,

a second half ring sized to receive the bottomrail, the second half ring having a top; and

a side wall extending from the bottom of the first half ring to the top of the second half ring, the sidewall, bottom of the first half ring, and top of the second half ring defining a cavity sized to receive the window covering; and

at least one partition within the cavity sized to receive the window covering material, the at least one partition being removable.

9. The method of claim 8 wherein the at least one collar is further comprised of a material selected from the group consisting of plastics, cardboard, polyvinyl chloride, and metal.

11. The method of claim 8 further comprising clamping the window covering material.

12. The method of claim 8 further comprising putting the blind in a package.

13. The method of claim 12, wherein the blind is put in the package after the at least one collar is attached to the blind.

14. The method of claim 8 wherein the window covering material is selected from the group consisting of a plurality of slats, pleated material and cellular material.
