ABSTRACT:
The present invention is an apparatus for guiding the edge of a free-falling curtain. The apparatus includes first and second slides positioned at the top of the curtain which merge. An edge guide is positioned at the point where the slides merge. A lubricating liquid is provided to each slide surface which flows down each slide and the edge guide to guide the edge of the free-falling curtain. The present invention allows time for surfactant in the lubricating liquid time to diffuse to the surface and promotes dampening of disturbances in the lubricating liquid.
