Abstract

Pentru a se putea decupa fara deseuri sau cu deseuri neînsemnate, tole de transformator în forma de E si tole de închidere posterioara în forma de I ale unei bobine de soc sau ale unui transformator în special pentru utilizarea ca element aditional legat în serie la lampi de iluminat cu gaze rarefiate doua rînduri de tole de transformator în forma de E se decupeaza cu partile deschise asezate fata în fata si una lînga alta si în asa fel deplasate între ele încît capetele bratelor exterioare asezate unul lînga altul a doua tole de transformator în forma de E învecinate sa se atinga de capatul bratului mijlociu al tolei de transformator în forma de E care este în fata lor deplasat. Din spatiile libere care exista între bratele exterioare si bratele mijlocii ale tolelor de transformator în forma de E asezate fata în fata se decupeaza tolele de închidere posterioara în forma de I.
