Abstract
618,246. Coating webs. BRUSH DEVELOPMENT CO. March 21, 1946, No. 8839. Convention date, April 18, 1945. Drawings to Specification. [Class 140] [Also in Groups XXXIV and XXXVIII] In a magnetic recording and reproducing apparatus using an endless steel tape, in which the tape is coiled on a disc and supported on a turntable, friction between the convolutions and between the tape and the turntable is reduced by the use of oiling devices. In one form the tape passes between the upper ends of wicks, the lower ends of which rest in a reservoir. In another form the edge of the turntable and the coil of tape is immersed in a reservoir of oil. In yet another form a directing fin on the bottom of the turntable extends into an oil reservoir and causes oil to be splashed through a slit in the turntable on to the tape.
