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.
Claims35
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.
A method of trimming a window covering product having a headrail, bottom rail and window covering material connected between the headrail and the bottom rail comprising,
- placing the window covering product in a blind cutting machine containing a support housing having a headrail opening, a slat opening and a bottom rail opening consecutively positioned along a vertical axis, such that a portion of each of the headrail, window covering material and bottom rail extends through the headrail opening, slat opening and bottom rail opening respectively;
- moving a headrail cutter along a first horizontal axis to cut the portion of the headrail;
- moving a bottom rail cutter along a second horizontal axis to cut the portion of the bottom rail;
- and
- thereafter moving a slat cutter along a vertical axis from a position below the headrail opening, slat opening and bottom rail opening to cut the portion of the window covering material.
A blind support table comprising 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 horizontal axis,
- a headrail cutter positioned adjacent the support housing along a vertical plane, the plane passing through the headrail opening, the headrail cutter movable along a vertical 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 vertical plane, the second vertical plane passing through the bottom rail opening, the bottom rail cutter movable along a second vertical 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 horizontal plane, the horizontal plane passing through the slat opening, the slat cutter movable along a horizontal axis from a rest position 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;
- at least one of a headrail cutter support and a bottom rail cutter support, the headrail cutter support being attached to the headrail cutter, such that movement of the headrail cutter support causes movement of the headrail cutter, and the bottom rail cutter support being attached to the bottom rail cutter, such that movement of the bottom rail cutter support causes movement of the bottom rail cutter;
- and
- wherein the at least one of the headrail cutter support and the bottom rail cutter support has a channel through which the window covering material cutter passes.
A method of trimming a window covering product having a headrail, bottom rail and window covering material connected between the headrail and the bottom rail comprising,
- placing the window covering product in a blind cutting machine containing a support housing having a headrail opening, a slat opening and
- a bottom rail opening consecutively positioned along a horizontal axis, such that a portion of each of the headrail, window covering material and bottom rail extends through the headrail opening, slat opening and bottom rail opening respectively;
- moving a headrail cutter attached to a headrail cutter support along a first vertical axis to cut the portion of the headrail;
- moving a bottom rail cutter attached to a bottom rail cutter support along a second vertical axis to cut the portion of the bottom rail;
- and
- thereafter moving a slat cutter through a channel formed in at least one of the headrail cutter support and the bottom rail cutter support along a horizontal axis to cut the portion of the window covering material.
