Abstract
A package of fiberglass is unwound such that the revolution of the unwinding is controlled relative to linear payout speed of the package. A strand of fiber is pulled from the package while simultaneously rotating the package about a longitudinal axis of the package.
Claims4
A process for making a warp beam of untwisted fiberglass strands comprising:
- (a) providing a fiberglass forming package with a single fiberglass strand wound on the package and having a longitudinal axis;
- (b) supporting the package in a manner that permits rotation of the package about the longitudinal axis;
- (c) pulling the single strand from the package along the longitudinal axis and simultaneously rotating the package about the longitudinal axis while maintaining a rotational surface speed of the package equal to a linear speed of pulling the single strand and in a direction of rotation such that the fiberglass strand is pulled off the package with a net zero amount of twist;
- and
- (d) wrapping the single strand which is pulled from the package onto a beam which can be used to form a warp beam.
