Abstract

A hybrid flute for a stalk roll may be configured with a sharp edge positioned between a first blunt edge and a second blunt edge along a length of the flute edge. The flute edge may extend radially outward from a main cylinder of the stalk roll. The flute edge may be engaged with a radius at the base of the flute edge, and a flute base may extend from the radius. A plurality of flute bases positioned adjacent to one another may be configured to form a main cylinder for the stalk roll.

Claims (27)

1. A stalk roll comprising:

a. a hybrid flute comprising:

i. a flute edge having a first blunt edge, a sharp edge, and a second blunt edge along a length of said hybrid flute;

ii. a radius engaged with and extending from said flute edge in a direction angled with respect to said flute edge;

iii. a flute base engaged with and extending from said radius;

b. a full flute comprising:

i. a flute edge along a length of said full flute;

ii. a radius engaged with and extending from said flute edge in a direction angled with respect to said flute edge;

iii. a flute base engaged with and extending from said radius;

iv. wherein said length of said full flute is less than said length of said hybrid flute, and wherein a distal edge of said flute base of said hybrid flute is positioned adjacent said radius of said full flute;

c. a reduced flute comprising:

i. a flute edge along a length of said reduced flute;

ii. a radius engaged with and extending from said flute edge in a direction angled with respect to said flute edge;

c. a flute base engaged with and extending from said radius;

d. wherein said length of said second reduced flute is less than said length of said reduced flute, and wherein a distal edge of said flute base of said reduced flute is positioned adjacent said radius of said second reduced flute.

3. The stalk roll according to claim 2 further comprising a short flute, said short flute comprising:

a. a flute edge along a length of said short flute;

b. a radius engaged with and extending from said flute edge in a direction angled with respect to said flute edge;

c. a flute base engaged with and extending from said radius;

d. wherein said length of said short flute is less than said length of said second reduced flute, and wherein a distal edge of said flute base of said second reduced flute is positioned adjacent said radius of said short flute.

4. The stalk roll according to claim 2 wherein said hybrid flute further comprises an axial face that is sloped backward with respect to said length of said hybrid flute.

5. The stalk roll according to claim 2 wherein said hybrid flute further comprises a base bevel on an area of said base adjacent said first blunt edge.
