DEFINITION

Classification: 400/611

For feeding web record-medium:

(under subclass 578) Subject matter wherein significance is attributed to means associated with a typewriter for moving a web of record-medium* relative to the typewriter.

(1) Note. The term "web" is discussed in the definition of "record-medium", in the Glossary, section III.

(2) Note. The movement of the web in this and indented subclasses is that which causes the web to enter or exit the typewriter, or to move in a line-space* direction or to move relative to a moving carriage*. Movement of the web (or any record-medium) by and with a moving carriage will be found in subclasses relating to the carriage, subclasses 283+.

(3) Note. The typewriter of this subclass may have a magnetic clutch drive for effecting web feed.
