Abstract
A pressure sensitive adhesive tape, such as a white typing correction tape, is wound up with backing tape or a liner tape wound between successive turns of the tape. The backing tape is cut into short lengths, and the correction tape is bent sharply back upon itself over a "peeling" member as it is dispensed, to separate the short lengths of the backing or liner tape and leave them behind in the carton. The space within the standard size dispenser package is adequate to hold the waste pieces of backing tape as the correction tape roll is used up. A short cutting blade may be provided to cut off desired lengths of the correction tape.
