1. A method of forming a first discrete portion and a second discrete portion from a first web, the method comprising the steps of: a. providing a first web;b. advancing the first web in a machine-direction to a converting mechanism, the converting mechanism comprising a rotary cutter comprising a first die cutter shape secured to the rotary cutter and a second die cutter shape secured to the rotary cutter, the first die cutter shape being different from the second die cutter shape;c. cutting the first web with the first die cutter shape secured to the rotary cutter to form the first discrete portion comprising a first shape without a linear cut edge in a cross-direction;d. separating the first discrete portion from the first web with the use of a vacuum, wherein the vacuum is pulled from within an anvil roll; ande. cutting the first web with the second die cutter shape secured to the rotary cutter to form the second discrete portion comprising a second shape that is different from the first shape of the first discrete portion; wherein cutting the first web with the first die cutter shape and the second die cutter shape provides the first web with the first shape followed by the second shape in an alternating sequence. 2. The method of claim 1 further comprising the step of removing the first web which is no longer attached to the first discrete portion. 3. The method of claim 1 further comprising the step of separating the second discrete portion from the first web. 4. The method of claim 1 wherein the first discrete portion is selected from the group consisting of a functional component of an absorbent article, a visual aesthetic component of an absorbent article, and combinations thereof. 5. The method of claim 4 wherein the first discrete portion comprises a design graphic. 6. The method of claim 1 wherein cutting the first web with the first die cutter shape secured to the rotary cutter to form the first discrete portion and separating the first discrete portion from the first web occur at the same time. 7. The method of claim 3 wherein cutting the first web with the second die cutter shape secured to the rotary cutter to form the second discrete portion and separating the second discrete portion from the first web occur at the same time. 8. The method of claim 1 wherein the alternating sequence provides the first web with the first discrete portion having the first shape followed by the second discrete portion having the second shape in a repeating sequence. 9. The method of claim 1 wherein the alternating sequence provides the first web with two discrete portions having the first shape followed by two discrete portions having the second shape in a repeating sequence. 10. The method of claim 1 wherein the first discrete portion is formed without having a connection to the second discrete portion. 11. A method of forming a first discrete portion and a second discrete portion from a first web, the method comprising the steps of: a. providing a first web;b. advancing the first web in a machine-direction to a converting mechanism, the converting mechanism comprising a rotary cutter comprising a first die cutter shape secured to the rotary cutter and a second die cutter shape secured to the rotary cutter, the first die cutter shape being different from the second die cutter shape;c. cutting the first web with the first die cutter shape secured to the rotary cutter to form the first discrete portion comprising a first shape without a linear cut edge in a cross-direction, wherein the first discrete portion is selected from the group consisting of a functional component of an absorbent article, a visual aesthetic component of an absorbent article, and combinations thereof;d. cutting the first web with the second die cutter shape secured to the rotary cutter to form the second discrete portion comprising a second shape that is different from the first shape of the first discrete portion; wherein cutting the first web with the first die cutter shape and the second die cutter shape provides the first web with the first shape followed by the second shape in an alternating sequence. 12. The method of claim 11 wherein the first discrete portion comprises a design graphic. 13. The method of claim 11 wherein the second discrete portion is selected from the group consisting of a functional component of an absorbent article, a visual aesthetic component of an absorbent article, and combinations thereof. 14. The method of claim 13 wherein the second discrete portion comprises a design graphic. 15. The method of claim 11, further comprising the steps of separating the first discrete portion from the first web; and separating the second discrete portion from the first web; wherein cutting the first web with the first die cutter shape secured to the rotary cutter to form the first discrete portion and separating the first discrete portion from the first web occur at the same time; and wherein cutting the first web with the second die cutter shape secured to the rotary cutter to form the second discrete portion and separating the second discrete portion from the first web occur at the same time. 16. The method of claim 11 wherein the alternating sequence provides the first web with the first discrete portion having the first shape followed by the second discrete portion having the second shape in a repeating sequence. 17. The method of claim 11 wherein the alternating sequence provides the first web with two discrete portions having the first shape followed by two discrete portions having the second shape in a repeating sequence. 18. The method of claim 11 wherein the first discrete portion is formed without having a connection to the second discrete portion.
