DEFINITION

Classification: 400/217

To shift impact path (e.g., during ribbon reversal):

(under subclass 211) Subject matter wherein the ribbon* is intended to receive multiple type-face* impacts along a first zone extending parallel to the elongated dimensions of the ribbon, and wherein significance is attributed to the manner of moving the ribbon transversely relative to its elongated dimension so that subsequent type-face impacts will be in a different zone transversely spaced from the first zone.
