  • Apparatus for imprinting intermittently advanced webs
    Patent number: 3934506
    Abstract: An apparatus for imprinting intermittently advanced webs has a carriage mounted for reciprocal displacement parallel to the web on a support. The web passes between a backup plate and a print roller rotatably mounted on the carriage. The carriage is displaced in one direction while the web is at rest, the print roller being coupled to the support for rotation during displacement of the carriage to effect printing by engaging the web against the backup plate. Printing is effected during displacement of the carriage in both directions.
