Abstract
A laminar air flow development device for use with stationary web material testing equipment is disclosed. The laminar air flow development device has a machine direction, a cross-machine direction orthogonal thereto, and a Z-direction orthogonal to both the machine and cross-machine directions. The stationary web material testing equipment has a first web material support having a Z-direction thickness, D. The device has first and second surfaces contactingly and matingly engaged to form an airfoil having a machine direction length, L, a cross-machine direction width, a leading edge, and a trailing end. The airfoil has a chord disposed between the first and second surfaces. The trailing end has a width equal to the Z-direction thickness, D. The device has a ratio of L/D ranging from about 1 to about 70 and provides machine direction laminar air flow to at least one surface of the first web material support.
