Abstract

A baler implement includes a first plate defining a first aperture for receiving a twine from a supply of the twine. A second plate defines a second aperture for discharging the twine to a knotter system. An elongated tube includes a first end defining a first opening, a second end defining a second opening, and defines an elongated interior passage extending between the first end and the second end. The first end of the elongated tube is positioned to align the first opening of the elongated tube with the first aperture of the first plate. The second end of the elongated tube is positioned to align the second opening of the elongated tube with the second aperture of the second plate. The elongated tube is shaped to guide the twine through the elongated interior passage thereof between the first aperture and the second aperture.

First claim

What is claimed is:

1. A baler implement comprising:
a baling chamber operable to form crop material into a bale;
a knotter system operable to wrap twine around a perimeter of the bale and tie a knot in the twine to secure the bale;
a first plate defining a first aperture and operable to receive a strand of twine from a twine storage box containing a supply of twine;
a second plate defining a second aperture and operable to discharge the strand of twine to the knotter system; and
an elongated tube having a first end defining a first opening, a second end defining a second opening, and defining an elongated interior passage extending between the first end and the second end;
wherein the first end of the elongated tube is positioned to align the first opening of the elongated tube with the first aperture of the first plate;
wherein the second end of the elongated tube is positioned to align the second opening of the elongated tube with the second aperture of the second plate;
wherein the elongated tube is shaped to guide the strand of twine through the elongated interior passage thereof between the first aperture and the second aperture;
wherein the knotter system includes a main gear tensioner operable to control a tension of the strand of twine to a desired tension value; and
wherein the second plate is positioned proximate the main gear tensioner to discharge the strand of twine into the main gear tensioner.

2. The baler implement set forth in claim 1 , wherein the twine storage box includes a wall defining the first plate.

3. The baler implement set forth in claim 1 , wherein the first plate is positioned proximate the twine storage box.

4. The baler implement set forth in claim 3 , wherein the second plate is positioned proximate the knotter system.

5. The baler implement set forth in claim 1 , wherein the elongated tube is flexible along a central longitudinal axis of the elongated tube, and wherein a cross section of the elongated tube perpendicular to the central longitudinal axis is geometrically stable.

6. The baler implement set forth in claim 1 , wherein the elongated tube is rigid and substantially inflexible.

7. The baler implement set forth in claim 1 , wherein the elongated tube is manufactured from one of a plastic, a metal, or a polymer.

8. The baler implement set forth in claim 1 , wherein the first end of the elongated tube is attached to the first plate.

9. The baler implement set forth in claim 1 , wherein the second end of the elongated tube is attached to the second plate.

10. The baler implement set forth in claim 1 , wherein the elongated tube includes a non-perforated wall forming the elongated interior passage.
