Abstract
Per evitare lo strappo di materiali estesi in lunghezza in conseguenza della contro-rotazione incontrollata dei sistemi di trasmissione, garantendo una corretta lavorazione, è previsto che la contro-rotazione delle singole parti di trasmissione (4) agisca, tramite il relativo motore (6) con regolatore (10) del regime di rotazione, su un trasmettitore di valore reale (17), venendo modificata, in assenza di valore nominale, in corrispondenza alla stazionarietà del motore d'azionamento (6), a contro-rotazione incipiente, questa direzione negativa in una positiva, e venendo governato, tale regolatore (10), da questo valore positivo, in modo da controllare il motore (6) attraverso la relativa parte di potenza (16), nel senso di rotazione originario, cosicché l'allentamento delle tensioni non abbia luogo, se non al limite assai lentamente, per effetto della deriva del regolatore. La invenzione trova principalmente impiego nelle trasmissioni a cinghia preposte a mezzi di trasporto di materiali sensibili estesi in lunghezza (Fig. 1).
