Abstract:
A method of maintaining the location of a fiber doff inner-diameter-tow at a point of payout within a constant inertial reference frame includes providing a flat fiber tow payout system with a center-pull doff of flat fiber tow that pays out at a point of payout along an inner diameter of the center-pull doff with rotation of the center-pull doff about a vertically oriented axis of rotation, the flat fiber tow payout system including a constant inertial reference frame for payout of the flat fiber tow along the inner diameter of the center-pull doff without twisting the flat fiber tow; and accelerating and stopping rotation of the center-pull doff with the flat fiber tow payout system so as to maintain payout of the flat fiber tow along the inner diameter of the center-pull doff in the constant inertial reference frame, preventing twisting of the flat fiber tow.
