Abstract

A system includes a source of sheet material and a conversion machine. The conversion machine is configured to receive the sheet material and to form the sheet material into a fill material. The conversion machine further includes a cutting system configured to selectively cut the fill material either partially or completely to form two pieces of the fill material. When the cutting system partially cuts the fill material, uncut portions of the fill material remain between the two pieces of the fill material. When the cutting system completely cuts the fill material, no uncut portions remain between the two pieces of the fill material.

First claim

What is claimed is:

1. A system comprising:
a source of sheet material; and
a conversion machine configured to receive the sheet material and to form the sheet material into a fill material;
a cutting system configured to selectively cut the fill material either partially or completely to form two pieces of the fill material, wherein:
when the cutting system partially cuts the fill material, a plurality of uncut portions of the fill material remain between the two pieces of the fill material; and
when the cutting system completely cuts the fill material, no uncut portions remain between the two pieces of the fill material;

wherein the cutting system includes a cutter in the form of a V-shaped blade; and
wherein, when the cutting system partially cuts the fill material, the V-shaped blade leaves the plurality of uncut portions of the fill material between the two pieces of the fill material.

2. The system of claim 1 , wherein, when the cutting system partially cuts the fill material, the uncut portions are arranged such that, when one of the two pieces of the fill material is pulled away from each other, the uncut portions tear, resulting in the two pieces of the fill material being separated from each other.

3. The system of claim 1 , wherein:
the cutting system includes a cutter receptacle; and
when the cutting system partially cuts the fill material, the cutter is moved to a point where a gap remains between a portion of the cutter and a portion of the cutter receptacle.

4. The system of claim 3 , wherein a width of the gap is a percentage of the width of the cutter that is less than or equal to 10%.

5. The system of claim 3 , wherein the portion of the cutter that forms the gap includes an angle of the V-shaped blade.

6. The system of claim 3 , wherein the cutting system further includes a motor configured to move the cutter with respect to the cutter receptacle.

7. The system of claim 6 , wherein the motor is coupled to a first linkage and configured to rotate the first linkage.

8. The system of claim 7 , wherein the first linkage is rotatably coupled to a second linkage and wherein the second linkage is rotatably coupled to the cutter.

9. The system of claim 8 , wherein the motor is configured to move the cutter by rotating the first linkage.

10. The system of claim 9 , wherein the motor is configured to cause the cutting system to make a complete cut by rotating the first linkage to a first rotational position, and wherein the motor is configured to cause the cutting system to make a partial cut by rotating the first linkage to a second rotational position that is different from the first rotational position.

11. The system of claim 1 , wherein, when the cutting system partially cuts the fill material, a percentage of a width of the fill material that remains connected by the uncut portions is in a range between about 1% and about 10%.

12. The system of claim 1 , wherein, when the cutting system partially cuts the fill material, a percentage of a width of the fill material that remains connected by each of the uncut portions is less than or equal to any one of 1%, 0.8%, 0.6%, 0.4%, or 0.2%.

13. A method comprising:
converting, by a fill conversion machine, a sheet material into a fill material;
cutting, by a cutting system of the fill conversion machine, the fill material to form two pieces of fill material, wherein the two pieces of fill material include a first piece and a second piece, wherein the fill conversion machine is capable of both:
making a partial cut of the fill material, wherein the partial cut leaves uncut portions of the fill material between the first and second pieces of the fill material, and
making a complete cut of the fill material, wherein the complete cut leaves no uncut portions remaining between the first and second pieces of the fill material;

wherein the cutting system includes a cutter in the form of a V-shaped blade; and
wherein, when making a partial cuts of the fill material, the V-shaped blade leaves the plurality of uncut portions of the fill material between the two pieces of the fill material.

14. The method of claim 13 , wherein cutting the fill material comprises making the partial cut, and wherein the method further comprises:
holding, by the conversion machine, a second piece of the two pieces of fill material;
wherein the first piece is separable from the second piece during the holding by pulling the first piece from the second piece to cause the uncut portions of the fill material to tear.

15. The method of claim 14 , further comprising:
detecting, by the conversion machine, that the first piece has been pulled away from the second piece.

16. The method of claim 15 , further comprising:
in response to the detecting, automatically advancing, by the conversion machine, the fill material out of the fill conversion machine;
in response to the detecting, automatically cutting, by the cutting system of the conversion machine, the fill material to form a cut between the second piece and a third piece of the fill material such that uncut portions of the fill material remain between the second and third pieces of fill material.

17. The method of claim 16 , further comprising:
holding, by the conversion machine, the third piece of fill material;
wherein the second piece is separable from the third piece during the holding of the third piece by pulling the second piece from the third piece to cause the uncut portions of the fill material between the second and third pieces to tear.

18. The method of claim 13 , further comprising:
receiving, by a computing device of the fill conversion machine, a user input indicating a type of cut to be made; and
controlling, by the computing device, the cutting system to make either the partial cut or the complete cut based at least in part on the user input.

19. The method of claim 13 , further comprising:
receiving, by a computing device of the fill conversion machine, a signal from a sensor; and
controlling, by the computing device, the cutting system to make either the partial cut or the complete cut based at least in part on the signal from the sensor.
