Abstract
Il trovato si inserisce nel campo delle macchine e dei procedimenti per il trattamento di fibre chimiche.Più precisamente si riferisce ad un procedimento di crettatura e ad una crettatrice meccanica in cui la spinta sul fascio di fibre in transito è esercitata da mezzi di spinta (1) atti a mantenere un contatto continuo e forzato con il fascio di fibre su una superficie estesa dello stesso.Detti mezzi di spinta (1) comprendono nastri chiusi (4) scorrevoli su rulli (2, 3) alla stessa velocità di ingresso del fascio di fibre.E' inoltre prevista un'iniezione di vapore nella direzione del moto del fascio di fibre e verso opposto.
