Abstract

Cambio di velocità a motori idrostatici particolarco di rotoli e falde di tessuto è del tipo comprenende un primo motore idrostatico ed un secondo motzialmente a semicerchio, nonché un rullo di trainospettivamente ad un primo contralbero e ad un secoimo è atto a passare da una posizione attiva di co trasmissione e secondi mezzi di trasmissione. Il one inattiva allontanata da detto rullo di traino.tano ciascuno una pluralità di ingranaggi d'ingres collegati a mezzi atti a portarli da una prima potralbero mediante mezzi di selezione. Questi ingratanzialmente in asse fra loro con disposizione sosi secondari onde definire rapporti marcia. Gli ingera per il trattamento di tessuti in falda. ondario a cui sono selettivamente vincolabili mediante i mezzi di selezione. Un primo ingranaggio d'uscita è calettato sull'albero secondario ed ingrana in un secondo ingranaggio d'uscita calettato su un albero di uscita.
