CA 2623039

Identity document processing equipment with a mechanism designed to maintain tension in a ribbon used in a processing operation in the processing equipment. The tension maintaining mechanism is separate from the supply roll and the take-up roll for the ribbon, eliminating the need for clutches or brakes attached to the supply or take- up rolls to achieve tensioning. Since the tension maintaining mechanism is separate from the supply roll and the take-up roll, the inertia of the supply roll or the take-up roll does not affect the tension on the ribbon during use of the processing equipment.

L'invention concerne un dispositif de traitement de documents d'identité pourvu d'un mécanisme destiné à maintenir la tension d'un ruban utilisé au cours d'une opération de traitement du dispositif de traitement. Le mécanisme destiné à maintenir la tension est séparé du rouleau d'alimentation et de l'enrouleur du ruban, éliminant le besoin de griffes ou de freins associés au rouleau d'alimentation ou à l'enrouleur pour assurer la tension. Etant donné que le mécanisme destiné à maintenir la tension est séparé du rouleau d'alimentation et de l'enrouleur, l'inertie du rouleau d'alimentation ou de l'enrouleur n'affecte pas la tension sur le ruban au cours de l'utilisation du dispositif de traitement.
