ABSTRACT:
A printing apparatus for webs continuously moving along a path wherein a printing head is cyclically displaced along a further path which includes a portion extending substantially along the web path, the printing head engaging the web against a displaceable back-up member while traversing said portion of its path, the print head being spaced from the web path during the remaining portion of each cycle. Apparatus is provided for selectively adjusting the velocity of the print head while in engagement with the web and back-up member so that the print head and web are moving at substantially the same velocity. The print head may be a heated die, in which case a heat-released pigment bearing strip is incrementally advanced to the region intermediate the print head and web when the print head is spaced from the web and is engaged against the web by the heated die when the print head engages the web.
