PROCESSO PER LA PRODUZIONE DI SCHERMI DI VARIE DIMENSIONI PER LAMPADE FLUORESCENTI E SCHERMI COSI' PRODOTTI

摘要

A process for manufacturing shields of different size for fluorescent lamps consists in the steps of: providing a support for powders in the form of a metallic strip having a width (L) equivalent to about the circumference of the smallest shield to be manufactured; depositing on said support strip at least one track of getter material and at least another of mercury releasing materials in powdered form; and producing pieces of the support strip by cutting the same with parallel cuts having a pitch (D) and at an angle ( alpha ) with respect to the central axis (X-X) of the strip which are both varying according to the desired size of the shield.
