DEFINITION

Classification: 400/517

By means to arrest advance of carbon paper:

(under subclass 513) Subject matter wherein the record-medium* is moved in a direction to line-space* the record-medium, and wherein the relative movement between the record-medium and said carbon paper is effected by means for preventing the carbon paper from moving, the relative movement occurring after the typing of one page* of text and before typing on a subsequent page of text.

(1) Note. During the typing of a page the record-medium and carbon paper materials are line-spaced together. The action described above occurs between pages, when the record-medium is advanced and the carbon paper remains stationary.
