An apparatus to extract cotton dust from the high velocity discharge of a cotton cleaning device is disclosed. Means for reduction and removal of fine trash and dust from cotton fiber is provided. At the high velocity discharge exit is placed a perforated cylinder rotating about an open-end stationary tube with an opening across its width. Fine trash and dust pass through perforations into a low pressure area inside the stationary tube and are discharged through a blower or suction source. Means to remove the cotton fiber to an intake duct from the cleaning device is provided as well as internal and adjustable external baffles.

Apparatus to extract fine trash and dust during high-velocity

An apparatus for drafting and parallelizing strands of fiber comprising three side-by-side rolls nested in three side-by-side troughs which conform to and are adjacent the bottoms of the three rolls. The rolls are rotated in the same direction at sequentially greater speeds. The first two rolls include fiber-combing teeth, and the third roll is composed of a smooth, rubber-like surface. The fibers pass sequentially around the bottoms of the three rolls through a very narrow gap between the rolls and troughs to emerge in a parallelized, drafted condition. The unit may be incorporated into a no-twist yarn system as the sole mechanism for drafting and parallelizing the fiber, to form no-twist yarn in a continuous manner; or be used in place of conventional drafting system.

Apparatus for making no-twist yarn

This invention relates to an apparatus and method for improving the homogeneity of textile fibers which are blended together in a textile drawing machine. Vertical posts are critically aligned with corresponding angled rods which are spaced between a pair of drafting rolls thus substantially forming a guide mechanism which allows for alternating silver of cotton and synthetic fibers to be placed one on the top of the other and drafted together thereby achieving a more uniform and homogeneous blend.

Fiber blending mechanism

By combination and interaction of mechanical and aerodynamic forces, textile fibers are doffed from a processing cylinder, purged of foreign matter, subdivided and directed into a network of conveying tubes, and distributed to a multiplicity of fiber by-passing condensers wherein fibers are continuously assembled into a uniform ribbon for subsequent textile processing. The invention encompasses unique means for by-passing excess fibers for collection and reprocessing.

Method of fiber distribution and ribbon forming

Prearranged ribbons of fiber leaving the front drafting roll are superimposed into layers by a composite sliver forming assembly before entering a trumpet. The composite sliver forming assembly consists of tubular guides extending at an angle from the front drafting roller to the trumpet entrance. The tubes are designed with a flat bottom to support the sliver, allowing for overlapping at the tube exit, and to achieve an exact ribbon exit 90.degree. downward into the trumpet entrance where the layered ribbons are combined into a composite sliver.
