<p>An intermediate feed mechanism in a label printing device enables correct registry of a printing plate with successive labels on a strip material backing, and easy adjustment of the intermittent feed in accordance with the label size, in a very simple and inexpensive manner. A drive wheel releasably secured for rotation with a print cylinder is provided, around only a portion of its periphery, with radially projecting pins for successive driving engagement with radially projecting pins uniformly distributed around the entire periphery of a driven wheel secured for rotation with an impression cylinder, so that the latter is driven only while the pins on the driving wheel are driven into contact with those on the driven wheel. The intermittent drive mechanism may also be employed in a label dispenser.</p> |
