Abstract: A coating apparatus is provided with a front roller and a rear roller which rotate in the same rotational sense and opposite to direction of rotation of a parallel cylinder to be coated with fluid material which hardens to a resilient coating thereon. A reservoir of fluid material is provided above a nip between the front and rear rollers, so that the front roller carries a layer of fluid material on a surface thereof to a nip formed between the front roller and the cylinder to be coated, thereby continuously building up thickness of the coating upon the cylinder. Heating elements and temperature sensors in a hood around the cylinder maintain an optimum coating temperature.

Abstract: Sheets or a web of bank note imprints are advanced in single file through an indexing station where a unique identifying index is applied to each imprint. The indexed imprints are stacked as a pile of strips, downstream of the indexing station, and the pile of strips cut into piles of individual indexed bank notes.Strips containing imprints with printing blemishes or incorrect indexes are rejected before reaching the stacking station. Computer-control of the indexing units in the indexing station maintains an unbroken sequence of indexes on the imprints advanced to the stacking station despite the presence of reject strips.
