Magnetic tape air bearing - has openings in side of cylinder covered by wire mesh for contactless support
Реферат: Magnetic tape making plant employs an air bearing which supports the moving tape without contact, consisting of a cylinder closed at both ends (1). Air is supplied through an inlet connection (6) and escapes through one or more openings (7, 8) in the side of the cylinder. The openings extend over that part of the cylinder surface over which the tape passes. The openings are covered from within by a metallic wire mesh (9) held in place by a spring (10). The spring is of a helical type and its free diameter is somewhat larger than that of the cylinder. The openings on the cylinder can be in the form of a helix laid around the surface of the cylinder.
