ABSTRACT:
A web control device is provided as a generally cylindrical hollow bar having a plurality of holes disposed thereon. Each of the plurality of holes is capable of providing fluid contact between the central portion and the outer portion of web control device. The web control device provides contact-less support of a moving web material and can reduce the Poisson lateral contraction in a moving and/or tensioned web material without wrinkling or significantly stretching the moving web material.
