The drawing is a sectional, top view of a lift-off adhesive tape cassette in which an endless back-up loop 1 is moved by friction of the loop 1 against the back of the tape 3. The increased thickness provided by the loop 1 results in an increased spread of impact during correction to assure full correction without highly precise registration of the type face during erasure.
