Abstract

A harvester head may include a roller having a groove and supporting a draper belt. The draper belt may include a web and an elastomeric belt guide projecting from web, wherein the belt guide has outer side surfaces extending at an angle of no greater than 100° relative to the second surface when the belt guide wrapping about the roller within the groove. The groove may have outer side surfaces, each outer side surface extending at angle of no greater than hundred degrees relative to an outer surface of the roller.

First claim

What is claimed is:

1. An apparatus comprising:
a draper belt for a head of a harvester, the draper belt to extend about a roller having an outer groove encircling the roller, the draper belt to be driven in a first direction and comprising:
a web having a first surface to carry crop material and a second surface to face the roller;
an elastomeric belt guide projecting from the second surface, the belt guide having outer side surfaces extending at an angle of no greater than 100° relative to the second surface when the belt guide is wrapping about the roller within the groove.

2. The apparatus of claim 1 , wherein the outer side surfaces are shaped and formed from a material so as to expand into abutment with interior side surfaces of the outer groove as the belt guide wraps about the roller within the groove.

3. The apparatus of claim 1 , wherein each of the outer side surfaces extends at an angle of less than 95° relative to the second surface when the belt guide is wrapping about the roller within the groove.

4. The apparatus of claim 1 , wherein each of the outer side surfaces extends at an acute angle relative to the second surface when the belt guide is wrapping about the roller within the groove.

5. The apparatus of claim 3 , wherein the groove has mouth having a width and wherein the elastomeric feature is sized such that the outer side surfaces are spaced by a first maximum distance less than the width along portions of the web in a flat state and are spaced by a second maximum distance greater than the width along portions of the belt guide wrapping about the roller within the groove.

6. The apparatus of claim 1 further comprising the roller, wherein the outer groove has inner side surfaces, each of the inner side surfaces extending at an angle of no greater than 100° relative to an outer surface of the roller.

7. The apparatus of claim 5 , wherein the inner side surfaces are perpendicular to the outer surface of the roller.

8. The apparatus of claim 5 , wherein the inner side surfaces extend at an acute angle with respect to the outer surface of the roller so as to form an undercut about the roller.

9. The apparatus of claim 5 , wherein each of the inner side surfaces extends at a first angle of no greater than 100° relative to the outer surface of the roller and wherein each of the outer side surfaces of the feature extend at second angle relative to the second surface when in a flat state, the second angle being greater than the first angle.

10. The apparatus of claim 1 , wherein the draper belt is an endless belt.

11. The apparatus of claim 1 , wherein the draper belt is a seamed belt.

12. The apparatus of claim 1 , wherein the belt guide continuously extends along a length of the belt.

13. The apparatus of claim 1 , wherein the belt guide is shaped and sized to occupy a first percent of a volume of the groove when in a flat state and occupies a second percent of the volume of the groove, greater than the first percent of the volume of the groove, when the belt guide is wrapping about the roller within the groove.

14. A harvester head comprising:
a first roller having first outer groove;
a second roller having a second outer groove;
a draper belt extending about the first roller and the second roller, the draper belt comprising:
a web having a first surface to carry crop material and a second surface to face the roller;
an elastomeric belt guide projecting from the second surface, the belt guide comprising:
a first portion in a flat state between the first roller and the second roller, the first portion having a first shape different than the outer groove; and
a second portion within the first outer groove, the second portion having a second shape, different than the first shape, in abutment with interior sides the first outer groove.

15. The harvester head of claim 14 , wherein the outer groove has inner side surfaces, each of the inner side surfaces extending at an angle of no greater than 100° relative to an outer surface of the roller.

16. The apparatus of claim 15 , wherein the inner side surfaces are perpendicular to the outer surface of the roller.

17. The apparatus of claim 15 , wherein the inner side surfaces extend at an acute angle with respect to the outer surface of the roller so as to form an undercut about the roller.

18. The apparatus of claim 15 , wherein each of the inner side surfaces extends at a first angle of no greater than 100° relative to the outer surface of the roller, wherein the belt guide has outer side surfaces and wherein each of the outer side surfaces of the belt guide extend at second angle relative to the second surface when in a flat state, the second angle being greater than the first angle.

19. A harvester head comprising:
a drive roller;
an idler roller, wherein the drive roller and the idler roller are to support a draper belt extending about the drive roller and the idler roller and wherein the drive roller and the idler roller each comprise an outer groove, the outer groove of the drive roller and the idler roller having inner side surfaces extending at an angle of no greater than 100° relative to an outer surface of the roller.

20. The harvester head of claim 19 , wherein the inner side surfaces extend at an angle of no greater than 95° relative to the outer surface of the roller.
