ABSTRACT:
This disclosure deals with a machine for printing indicia on a moving web. The web may consist of a long relatively narrow carrier strip having rows of tax stamps or decals formed thereon, and the machine prints indicia in the form of code symbols on each stamp. The stamps are arranged on the carrier strip in rows which extend longitudinally or in the direction of the length of the strip, and the strip is moved longitudinally through the machine during the printing operation. In the described example of the invention, a plurality of such rows are provided, the rows being laterally spaced across the width of the web, and the laterally adjacent stamps are arranged in laterally extending straight lines. The machine prints a group of symbols on each stamp, and the symbols are the same for every stamp on a given length of the web. The machine includes a plurality of printing cylinders or rollers which are spaced longitudinally of the web and which are moved in an oscillating or reciprocating motion toward and away from the web. The number of printing cylinders equals the number of symbols in each group, and each cylinder prints one symbol of each group. The associated printing elements which print a group of symbols are laterally offset relative to each other, in order to produce a side-by-side relation of the symbols of each group. The printing cylinders may be angularly adjusted to change the operative printing elements. The machine further includes mechanisms for handling a length of an inked ribbon or carbon paper and a control circuit for the machine, and the machine performs the multiple functions of separating a large web roll into a plurality of small rolls, and of cleaning the web.
