Abstract

A method of separating carbon fiber tows. The method includes separating two or more first carbon fiber tows from a first tow band onto a second elevation to form two or more second carbon fiber tows from a second tow band. The two or more second carbon fiber tows from the second tow band leave gaps next to first adjacent tows of the two or more first carbon fiber tows remaining from the first tow band after the separating step. The first adjacent tows from the first tow band leave gaps next to second adjacent tows of the two or more second carbon fiber tows from the second tow band.
