  • Air doffing system for a textile processing machine
    Patent number: 5930871
    Abstract: An air doffing system for a fiber-processing machine which includes an air plenum associated with a carding roll. A doffing blade initiates lifting of fibers from a carding roll, and a laminar airflow pulls the fibers through the plenum. The airflow is pulled through a perforated roll on the opposite end of the plenum. The perforated roll operates in connection with a smooth roll to form a roller pair which work the fibers collected on the perforated into a web. The web is then formed into a sliver by a trumpet and a calendar roll pair.
