Abstract

A roll for an agricultural baler includes: a cylinder including an outer cylindrical surface and an interior space, the cylinder being at least partially formed by a first end segment and a second end segment held together, the first end segment and the second end segment each having a respective interior wall with a wall opening in the interior space; a connector placed in each wall opening and bearing against the respective interior walls of the first end segment and the second end segment to hold the first end segment and the second end segment together; and a plurality of loops extending from the outer cylindrical surface.

First claim

What is claimed is:

1. A roll for an agricultural baler, comprising:
a cylinder comprising an outer cylindrical surface and an interior space, the cylinder being at least partially formed by a first end segment and a second end segment held together, the first end segment and the second end segment each comprising a respective interior wall comprising a wall opening in the interior space;
a connector having opposing ends, each of the opposing ends placed in the wall openings of the respective interior walls of the first end segment and the second end segment and bearing against the respective interior walls of the first end segment and the second end segment to hold the first end segment and the second end segment together;
a bearing and cap assembly placed at each of opposing ends of the cylinder adjacent to the respective interior walls, wherein each of the bearing and cap assemblies is separately spaced from the respective interior walls and respective ones of the ends of the connector; and
a plurality of loops extending from the outer cylindrical surface.

2. The roll of claim 1 , wherein the cylinder further comprises at least one middle segment held between the first end segment and the second end segment.

3. The roll of claim 2 , wherein the first end segment, the second end segment, and the at least one middle segment each comprises a cylindrical portion and a loop portion integrally formed with the cylindrical portion.

4. The roll of claim 3 , wherein the cylindrical portion and the loop portion are an integral casting.

5. The roll of claim 3 , wherein each of the cylindrical portions of the first end segment, the second end segment, and the at least one middle segment comprises an end face with a pin opening formed therein.

6. The roll of claim 5 , further comprising a first dowel pin placed in a respective pin opening of both the first end segment and the at least one middle segment and a second dowel pin placed in a respective pin opening of both the second end segment and the at least one middle segment.

7. The roll of claim 3 , wherein the at least one middle segment comprises a middle interior wall comprising a middle wall opening in the interior space, the connector extending through the middle wall opening.

8. The roll of claim 2 , further comprising a first loop segment held between the first end segment and the at least one middle segment and a second loop segment held between the second end segment and the at least one middle segment, the first loop segment and the second loop segment each comprising at least one of the plurality of loops.

9. The roll of claim 8 , wherein the first end segment, the second end segment, and the at least one middle segment comprise at least one end face, the first loop segment and the second loop segment each comprising an interior ring that bears against a respective end face of the first end segment, the second end segment, and the at least one middle segment.

10. The roll of claim 8 , wherein the first end segment and the second end segment are identical.

11. An agricultural baler, comprising:
a chassis;
a baling chamber carried by the chassis; and
a roll disposed in the baling chamber, the roll comprising:
a cylinder comprising an outer cylindrical surface and an interior space, the cylinder being at least partially formed by a first end segment and a second end segment held together, the first end segment and the second end segment each comprising a respective interior wall comprising a wall opening in the interior space;
a connector having opposing ends, each of the opposing ends placed in the wall openings of the respective interior walls of the first end segment and the second end segment and bearing against the respective interior walls of the first end segment and the second end segment to hold the first end segment and the second end segment together;
a bearing and cap assembly placed at each of opposing ends of the cylinder adjacent to the respective interior walls, wherein each of the bearing and cap assemblies is separately spaced from the respective interior walls and respective ones of the ends of the connector; and
a plurality of loops extending from the outer cylindrical surface.

12. The agricultural baler of claim 11 , wherein the cylinder further comprises at least one middle segment held between the first end segment and the second end segment.

13. The agricultural baler of claim 12 , wherein the first end segment, the second end segment, and the at least one middle segment each comprises a cylindrical portion and a loop portion integrally formed with the cylindrical portion.

14. The agricultural baler of claim 13 , wherein the cylindrical portion and the loop portion are an integral casting.

15. The agricultural baler of claim 13 , wherein each of the cylindrical portions of the first end segment, the second end segment, and the at least one middle segment comprises an end face with a pin opening formed therein.

16. The agricultural baler of claim 15 , further comprising a first dowel pin placed in a respective pin opening of both the first end segment and the at least one middle segment and a second dowel pin placed in a respective pin opening of both the second end segment and the at least one middle segment.

17. The agricultural baler of claim 13 , wherein the at least one middle segment comprises a middle interior wall comprising a middle wall opening in the interior space, the connector extending through the middle wall opening.

18. The agricultural baler of claim 12 , further comprising a first loop segment held between the first end segment and the at least one middle segment and a second loop segment held between the second end segment and the at least one middle segment, the first loop segment and the second loop segment each comprising at least one of the plurality of loops.

19. The agricultural baler of claim 18 , wherein the first end segment, the second end segment, and the at least one middle segment comprise at least one end face, the first loop segment and the second loop segment each comprising an interior ring that bears against a respective end face of the first end segment, the second end segment, and the at least one middle segment.

20. The agricultural baler of claim 18 , wherein the first end segment and the second end segment are identical.
