Abstract
This disclosure relates to a novel method of and apparatus for producing an open non-woven fabric from fibrous material by delivering the fiber flocks through a carding zone during which time the fiber flocks are loosened and spread to form a non-woven fabric, subjecting the spread-out non-woven fabric to a jamming effect in a jamming zone downstream of the carding zone to form a non-woven fabric of matted fibers, and releasing the jamming effect to form an open non-woven fabric.
