Process for the adaptation of the frequencies of an oscillating circuit composita sheet metal - Plastic - metal to a tag identification sheet suitable for achievement and compositaThe process

摘要

A resonant circuit formed by a composite laminate of metal-synthetic material-metal, for use as an identification label, with resonant frequency band below the nominal value, is adjusted to the desired value by passing it in roll form (1) between analyser cells (5, 6) for measuring frequencies, and under a shorting unit (7) situated between them, controlled by correction unit (8). @(Dwg.No 1/1)@.
