Abstract

Apparatus for printing indicia upon a continuous paper web, and including an ink retaining robbon, supply and take-up reels for the ribbon, and with a web path for the paper web and ink ribbon being defined, and with a printing station situated in the web paths. The printing station includes a numbering machine with indicia to be printed, with the printing station further including a skate assembly which carries a rotatable pressure ring. The skate assembly is mounted upon an endless belt, and is arranged to run in a direction transverse to the paper web path. A single motor means is provided, and includes a first drive for providing intermittent draw-dwell motion to the paper web, while providing continuous motion of the endless belt carrying the skate assembly. The skate assembly is timed to move across the paper during paper dwell periods.

Claims

1. Apparatus for printing indicia upon a continuous pre-punched paper web and comprising, in combination:

(a) frame means, first means mounted on said frame means for supporting a paper supply and an ink ribbon supply, and second means mounted on said frame means to carry the paper and ink ribbons along first and second web paths respectively and with said paper and ink ribbons sharing a common zone along said first and second web paths;

(b) a printing station adjustably positioned along a portion only of said frame means and disposed along the common zone of said first and second web paths and including;

(1) a numbering machine with numeral carrying numbering wheels therein, and with means for sequentially advancing selected numbering wheels;

(2) a continuously moving rotatable pressure ring mounted in an assembly for rotational contact with the surface of paper to be imprinted in said printing station; and

(3) endless belt means arranged to provide continuous motion for pulling said rotatable pressure ring assembly across said numbering machine;

(c) motor means including first drive means for providing simultaneous and intermittent draw/dwell motion to said paper and ink ribbon webs, and second drive means for simultaneously providing continuous motion to said endless belt and rotatable pressure ring assembly, and with said endless belt means including timing belt means for carrying said rotatable pressure ring assembly across said printing station during paper web and ink ribbon dwell, and to force said paper and ink webs together in face-to-face indicia printing relationship adjacent said pressure ring in said printing station.
