DATA WEB GUIDING APPARATUS

摘要

A data web guiding apparatus is disclosed which allows precision movement of a data web past a reading and writing transducer. A pair of rotatable cylinders are positioned in parallel spaced relation to each other for defining a plane over which the data web is passed. Fixedly mounted in spaced relation to a first end of each of these cylinders is a flange. At the other end of each of these cylinders is mounted a spring rail. The spring rails contact an edge of the data web and bias the web toward the fixed flanges as the web passes over the cylinders. When magnetic tape is used as the data web, precision movement of the tape past the guiding apparatus is achieved, in spite of variations in tape width due to temperature, humidity, or uneven cutting of the edges, with edge wear being held to a minimum under all such conditions.
