Abstract

La presente invenzione si riferisce ad un dispositivo di controllo della convergenza statica e della purezza per un tubo a raggi catodici tricromatico a cannoni elettronici in linea, comportante una striscia magnetizzabile destinata a circondare la sezione a collo del tubo e mezzi per il mantenimento della striscia sulla sezione a collo, sotto forma di una pellicola presentante la propria faccia adesiva a contatto con detta striscia, caratterizzato dal fatto che lo spessore di almeno una delle estremità della striscia, destinate ad unirsi nel corso dell'avvolgimento attorno al collo, diminuisce gradualmente.
