Abstract

A round baler is provided. The baler includes a bale forming chamber having a belt to form a bale of crop material. The baler also includes a wrap feed system. The baler includes a belt guide coupled to the baler so as to be external to the bale forming chamber. The belt guide includes an inwardly facing surface substantially parallel to the belt. The belt guide includes a protrusion extending inwardly towards the bale forming chamber. The protrusion is positioned adjacent a side of the belt. The belt guide is configured to sandwich wrap material between the belt and the belt guide.

First claim

What is claimed is:

1. A round baler comprising:
a bale forming chamber having a belt to form a bale of crop material;
a wrap feed system; and
a belt guide coupled to the baler so as to be external to the bale forming chamber, the belt guide comprising:
a guide body having an inwardly facing surface configured to contact the belt or wrap material and defining an opening in the guide body; and
a guide having a protrusion extending through the opening in the guide body inwardly towards the bale forming chamber adjacent an edge of the belt;
wherein the belt guide is configured to sandwich the wrap material between the belt and the inwardly facing surface of the guide body.

2. The round baler of claim 1 , wherein the wrap material is sandwiched between the inwardly facing surface and an external surface of the belt.

3. The round baler of claim 2 , wherein the wrap material flows over the protrusion of the belt guide along the edge the belt.

4. The round baler of claim 3 , wherein the bale forming chamber further comprises a roller, the belt guide being positioned proximate the roller.

5. The round baler of claim 1 , wherein the belt guide further comprises:
a hinge coupled to the guide at a first end, the hinge having a second end that cooperates with the guide and the guide body to receive a portion of the baler to couple the belt guide to the baler such that the belt guide is external to the bale forming chamber.

6. The round baler of claim 5 , wherein the guide body includes a coupling portion, and the hinge includes a mounting portion at the second end that cooperates with the coupling portion to couple the belt guide to the portion of the baler.

7. The round baler of claim 5 , wherein the portion of the baler is a cross-member associated with the wrap feed system.

8. The round baler of claim 1 , wherein the guide body is fixedly coupled to the guide.

9. A round baler comprising:
a bale forming chamber having a belt to form a bale of crop material, the belt supported on a roller;
a wrap feed system; and
a belt guide coupled to the baler so as to be external to the bale forming chamber and proximate the roller, the belt guide comprising:
a guide body having an inwardly facing surface configured to contact the belt or wrap material and defining an opening in the guide body; and
a guide having a protrusion extending through the opening in the guide body inwardly towards the bale forming chamber adjacent an edge of the belt;
wherein the belt guide is configured to sandwich wrap material between the belt and the inwardly facing surface of the guide body, and the wrap material flows over the protrusion of the belt guide along the edge the belt.

10. The round baler of claim 9 , wherein the wrap material is sandwiched between the inwardly facing surface and an external surface of the belt.

11. The round baler of claim 9 , wherein the belt guide further comprises:
a hinge coupled to the guide at a first end, the hinge having a second end that cooperates with the guide and the guide body to receive a portion of the baler to couple the belt guide to the baler such that the belt guide is external to the bale forming chamber.

12. The round baler of claim 11 , wherein the guide body includes a coupling portion, and the hinge includes a mounting portion at the second end that cooperates with the coupling portion to couple the belt guide to the portion of the baler.

13. The round baler of claim 12 , wherein the portion of the baler is a cross-member associated with the wrap feed system.

14. The round baler of claim 9 , wherein the opening in the guide body defines a slot, and the protrusion extends through the slot such that the protrusion extends a distance above the inwardly facing surface.

15. A round baler comprising:
a bale forming chamber having a belt to form a bale of crop material, the belt supported on a roller;
a wrap feed system; and
a belt guide coupled to the baler so as to be external to the bale forming chamber and proximate the roller, the belt guide comprising:
a guide body having an inwardly facing surface configured to contact the belt or wrap material and defining an opening in the guide body; and
a guide having a protrusion extending through the opening in the guide body inwardly towards the bale forming chamber adjacent an edge of the belt;
wherein the belt guide is configured to sandwich wrap material between the inwardly facing surface and an external surface of the belt.

16. The round baler of claim 15 , wherein the wrap material flows over the protrusion of the belt guide along the edge the belt.

17. The round baler of claim 15 , wherein the belt guide further comprises:
a hinge coupled to the guide at a first end, the hinge having a second end that cooperates with the guide and the guide body to receive a portion of the baler to couple the belt guide to the baler such that the belt guide is external to the bale forming chamber.
