Abstract

Strip 3 can be used in magnetic strip storage devices to reduce wear and friction resulting from high-speed passage of strips through guides or other transport apparatus by providing air lubrication. The leading edge is given a permanent set by the downward bend at 5. The dimensions A, B, and C are not critical and they can be only a few thousandths of an inch. When strip 3 travels along a guide, air, acting against the downward slope of the leading edge, maintains the edge in light contact with the guide, which prevents flying away from flat or curved guide 4. The slight rise, as shown at 5, then provides an entry channel for air at the sides of strip 8, together with a converging air space behind 5 that is favorable to maintenance of an air film. This prevents contact of the strip portion behind 5 with guide 4.
