DEFINITION

Classification: 400/519.2

Including means to reduce binding of carbon paper during retraction:

(under subclass 519) Subject matter wherein said carbon paper carrier is moved with respect to the platen* in a return direction opposite to the line-space* direction of the record-medium*, and wherein a tendency for the carbon paper to stick to the record-medium, is lessened.

(1) Note. As plural manifold sets of carbon paper and record-medium are typed on, there is a tendency for the carbon paper to stick to the record-medium, which makes it difficult to retract the carbon paper from the platen. The construction provided for in this and indented subclasses enables the separation of the carbon paper from the record-medium, thus facilitating the retraction.
