Abstract

Macchina per cucire comprendente un gancio che gira in unione ad un albero principale della macchina per cucire e una bobina montata rotativamente sul gancio. Un primo mezzo rivelatore (6, 7a) rivela la velocità di rotazione dell'albero principale, mentre un secondo mezzo rivelatore (3a, 3b, 7b) rivela la velocità di rotazione della bobina. Mezzi comparatori (8) sensibili al secondo mezzo rivelatore (3a, 3b, 7b) generano un segnale quando la velocità di rotazione della bobina supera un valore predeterminato; in tal modo, i mezzi di controllo (8) azionano un mezzo di segnalazione.
