DEFINITION

Classification: 400/616

By pin-feed means (e.g., reciprocating pin, etc.):

(under subclass 611) Subject matter wherein the means for moving a web of record-medium* includes at least one short, slender element that is configured to enter into a hole in the web and is moved in a direction parallel to the line-space* direction to thereby move the web.

(1) Note. In this subclass the pin reciprocates to-and-fro, engaging the web in one of its movements and disengaging from the web in the return movement.
