Abstract

In a cutting machine for cutting down venetian blinds a headrail cutter and a bottom rail cutter are provided which move along a horizontal axis. After the headrail and bottom rail are trimmed a slat cutter moves in a vertical axis, up or down to cut the slats. The cutting machine enables one to cut down a venetian blind while the opposite end of the blind remains in the packing box. Preferably, a spacer or collar is provided on the blind prior to packaging so that the headrail, window covering material and bottom rail will be spaced apart from one another a desired amount. That spacing should be the same spacing as the openings in the cutting machine so that when one end of the blind is removed from the package that end of the blind can be readily inserted into the cutting mechanism.

Claims

1. A blind cutting machine comprised of:

a blind support table having a surface on which a blind to be cut is placed, and

a cutting mechanism adjacent to the support table, the cutting mechanism comprised of;

a support housing having a headrail opening, a slat opening and a bottom rail opening consecutively positioned along a vertical axis,

a headrail cutter positioned adjacent the support housing along a horizontal plane, the plane passing through the headrail opening, the headrail cutter movable along a horizontal axis from a rest position to a finish position such that when the headrail cutter is moved from the rest position to the finish position any portion of a headrail extending through the headrail opening will be cut by the headrail cutter;

a bottom rail cutter positioned adjacent the support housing along a second horizontal plane, the second horizontal plane passing through the bottom rail opening, the bottom rail cutter movable along a second horizontal axis from a rest position to a finish position such that when the bottom rail cutter is moved from the rest position to the finish position any portion of a bottom rail extending through the bottom rail opening will be cut by the bottom rail cutter;

a slat cutter positioned adjacent the support housing along a vertical plane, the vertical plane passing through the slat opening, the slat cutter movable along a vertical axis from a rest position below the headrail opening, slat opening and bottom rail opening to a finish position such that when the slat cutter is moved from the rest position to the finish position any portion of slats extending through the slat opening will be cut by the slat cutter;

wherein the headrail cutter and the bottom rail cutter are sized and configured such that neither cutter passes over the slat opening when moved from a rest position to a finish position, and

a headrail cutter support, the headrail cutter being attached to a headrail cutter support, such that movement of the headrail cutter support moves the headrail cutter and wherein the headrail cutter support contains a channel through which the slat cutter passes when the headrail cutter is in the finish position.

2. The blind cutting machine of claim 1 wherein the headrail opening, the slat opening and the bottom rail opening are sufficiently close to one another that one end of a venetian blind can be inserted into the headrail opening, the slat opening and bottom rail opening while an opposite end of the venetian blind is within a packaging box.

3. The blind cutting machine of claim 1 also comprising a movable blade support to which the headrail cutter and the bottom rail cutter are attached.

4. The blind cutting machine of claim 1 also comprising a movable end stop attached to at least one of the cutting mechanism and the blind support table.

5. The blind cutting machine of claim 1 also comprising a first actuator connected to the headrail cutter and the bottom rail cutter for simultaneously moving the headrail cutter and the bottom rail cutter from their rest positions to their finish positions;

a second actuator connected to the slat cutter for moving the slat cutter from its rest position to its finish position; and

a controller connected to the first actuator and the second actuator.

6. The blind cutting machine of claim 5 also comprising a sensor connected to the controller and positioned to determine when a venetian blind is within the headrail opening, the slat opening and the bottom rail opening.

7. The blind cutting machine of claim 1 wherein at least one of the headrail opening, the slat opening and the bottom rail opening is tapered.

8. The blind cutting machine of claim 1 wherein the support housing has a second headrail opening, a second slat opening and a second bottom rail opening consecutively positioned along a second vertical axis.

9. The blind cutting machine of claim 8 wherein the support housing has a third headrail opening.

10. The blind cutting machine of claim 8 wherein the second headrail opening, the second slat opening and the second bottom rail opening are sufficiently close to one another that one end of a venetian blind can be inserted into the second headrail opening, the second slat opening and the second bottom rail opening while an opposite end of the venetian blind is within a packaging box.

11. The blind cutting machine of claim 8 wherein the second slat opening is larger than the slat opening.

12. The blind cutting machine of claim 1 wherein at least one of the headrail cutter and the bottom rail cutter is a cutting die.

13. The blind cutting machine of claim 1 wherein at least one of the headrail cutter, the slat cutter and the bottom rail cutter is a blade.

14. The blind cutting machine of claim 1 also comprising a clamping mechanism attached to the support housing.

15. A blind cutting machine comprised of:

a blind support table having a surface on which a blind to be cut is placed, and

a cutting mechanism adjacent to the support table, the cutting mechanism comprised of;

a support housing having a headrail opening, a slat opening and a bottom rail opening consecutively positioned along a vertical axis,

a headrail cutter positioned adjacent the support housing along a horizontal plane, the plane passing through the headrail opening, the headrail cutter movable along a horizontal axis from a rest position to a finish position such that when the headrail cutter is moved from the rest position to the finish position any portion of a headrail extending through the headrail opening will be cut by the headrail cutter;

a bottom rail cutter positioned adjacent the support housing along a second horizontal plane, the second horizontal plane passing through the bottom rail opening, the bottom rail cutter movable along a second horizontal axis from a rest position to a finish position such that when the bottom rail cutter is moved from the rest position to the finish position any portion of a bottom rail extending through the bottom rail opening will be cut by the bottom rail cutter; and

a slat cutter positioned adjacent the support housing along a vertical plane, the vertical plane passing through the slat opening, the slat cutter movable along a vertical axis from a rest position below the headrail opening, slat opening and bottom rail opening to a finish position such that when the slat cutter is moved from the rest position to the finish position any portion of slats extending through the slat opening will be cut by the slat cutter;

wherein the headrail cutter and the bottom rail cutter are sized and configured such that neither cutter passes over the slat opening when moved from a rest position to a finish position, and

a bottom rail cutter support, the bottom rail cutter being attached to a bottom rail cutter support, such that movement of the bottom rail cutter support moves the bottom rail cutter and wherein the bottom rail cutter support contains a channel through which the slat cutter passes when the bottom rail cutter is in the finish position.
