Unit for feeding and applying seals to security cassettes for banknotes

摘要

Banknotes are placed for transportation purposes in cassettes comprising a container and a hinged lid, made secure by applying a seal composed of two parts that can be coupled non-releasably and are provided with latch elements appearing as curved teeth positioned to locate in the holes of lugs associated with the container and with the lid. The seals, loaded into a magazine with the two parts spread, are fed and applied to the cassettes by a unit comprising a clamp assembly with retaining pins designed to pick up the seals from an outlet of the magazine and transfer them to a gripper head presenting a pair of arms by which the two parts are taken up and restrained; the arms are mounted to respective pivots on the gripper head so that when the head is made to assume a final operating position adjacent to the lugs on the cassette, the arms can be rotated toward one another, causing the two parts of the seal to couple together with the curved teeth engaging the holes of the lugs, securing the cassette.
