Apparatus To Uniformly Control Wrapping A Filament Around The Surface Of A Spun Core Yarn During Ring Spinning
US Patent:
4365464, Dec 28, 1982
Filed:
Jan 28, 1981
Appl. No.:
6/229217
Inventors:
Clarence O. Graham - New Orleans LA
Charles L. Shepard - Chalmette LA
Russell M. H. Kullman - Harahan LA

Assignee:

Agriculture - Washington DC
International Classification:
D02G 336
US Classification:
57 12
Abstract:
An apparatus to uniformly wrap filament around the surface of a spun core yarn is disclosed. Means for fabricating a core yarn is provided. At the critical point of yarn fabrication, the spun core is simultaneously twisted or rotated on its longitudinal axis by means of ring spinning and contacted with a filament introduced by means of over-feed rollers. Helical wrapping of the filament around the surface of the staple core yarn takes place as the filament cohesively contacts the twisting core yarn to form a composite filament wound yarn.
Process For Reinforced Yarn With Glass Fiber Core
US Patent:

Filed:

International Classification:
D02G 316, D02G 328
US Classification:
57 12
Abstract:
A unique process for producing torque-free or balanced yarns of staple fibers with glass filament cores is disclosed. Staple fiber roving is fed through a drafting system. Glass filament is fed into the center of the staple fiber just prior to entering the front rolls of the drafting system. Sufficient twist is applied to the fiber around the glass filament using the ring spinning process and two or more of these yarns are ply twisted in the opposite direction of the spinning direction to firmly lock the staple fiber to the glass filament. The twist multiplier range for spinning is between 3. 0 to 3. 5 and for plying is betwen 3. 5 and 4. 5. Cotton fiber is the principle fiber used with a glass filament core. The resulting yarn can be tied by knotting onto existing loom beam ends when breaks occur during weaving without shearing of the yarns.
Composite Sliver Forming Assembly
US Patent:
3994046, Nov 30, 1976
Filed:
Aug 14, 1975
Appl. No.:

International Classification:
D01H 572
US Classification:
19150
Abstract:
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.
Fiber Blending Mechanism
US Patent:
4016629, Apr 12, 1977
Filed:
May 22, 1975
Appl. No.:

International Classification:
D01G 500
US Classification:
19243
Abstract:
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.
