Abstract
A masking unit for bowling lanes equipped with automatic pinsetters, comprising a vertically moving masking panel and a series of stepped panels in front of the moving panel and extending from the top thereof to the ceiling of the bowling establishment. Stanchions at each end of a panel hold wheeled carriages which engage tracks on the back of the moving panel so that the panel may be vertically raised and lowered. Chain driven control means assures that one end of the panel does not get ahead of the other when the panel is being moved, and spring biasing means aid in raising the panel.
