Patent number: 5598694Abstract: An apparatus for making alternate S and Z twist plied yarn from individual singles yarns. The apparatus twists the singles yarns as they move in a path through the process, twisting the individual yarns in either an S or Z direction. The bonding of the ply-twisted yarns at a node while applying twist forms a bond characterized by a dense region of filaments adhesively joined together where one of the strands overlaps another strand, followed by a less dense region along the one strand where fewer filaments are adhesively joined, followed by another dense region.Type: GrantFiled: May 23, 1995Date of Patent: February 4, 1997Assignee: E. I. Du Pont de Nemours and CompanyInventors: Donald W. Edwards, Judith E. Hodgson, Steven K. Shibata, Harold F. Staunton, Robert E. Taylor, Paul W. Yngve

Patent number: 5557915Abstract: An alternate twist plied yarn formed from a plurality of strands of singles yarn twisted in alternating directions in lengthwise intervals of first half-cycles of twist at a predetermined twist level followed by second half-cycles of twist at the same twist level with reversal nodes therebetween, the singles twisted yarns being ply-twisted together in alternating directions in lengthwise intervals of first half-cycles of ply-twist followed by second half-cycles of ply-twist, there being a bond formed adjacent each node wherein the first half-cycle of ply-twist is located within the bond and the second half-cycle of ply-twist originates at one end of the bond, the twist level in the singles twisted yarn is between 25% in the same direction and 60% in the opposite direction of the twist applied to the singles yarns before plying.Type: GrantFiled: November 14, 1994Date of Patent: September 24, 1996Assignee: E. I. Du Pont de Nemours and CompanyInventors: Warren F. Knoff, Robert W. McAllister, Peter Popper, Steven K. Shibata, Robert E. Taylor, Paul W. Yngve

Patent number: 5465566Abstract: A system for bonding alternate S and Z twist plied yarn. The system bonds the plied yarns as they move in a path through the process and permits balanced expansion of the yarn while preventing lateral movement out of the path. The bonding of the yarn strands while plied together, forms a bond characterized by a dense region of filaments adhesively joined together where one of the strands overlaps another strand, followed by a less dense region along the one strand where fewer filaments are adhesively joined, followed by another dense region.Type: GrantFiled: June 8, 1993Date of Patent: November 14, 1995Assignee: E. I. Du Pont de Nemours and CompanyInventors: Donald W. Edwards, Craig A. Jackson, Steven K. Shibata, Paul W. Yngve

Patent number: 5228282Abstract: An apparatus for making alternate S and Z twist plied yarn from individual singles yarns. The apparatus twists the singles yarns as they move in a path through the process, twisting the individual yarns in either an S or Z direction. The bonding of the ply-twisted yarns at a node while applying twist forms a bond characterized by numerous individual spaced bond sites between individual filaments that are distributed throughout the bond.Type: GrantFiled: September 23, 1992Date of Patent: July 20, 1993Assignee: E. I. Du Pont de Nemours and CompanyInventors: Otis B. Tinsley, Paul W. Yngve

Patent number: 5012636Abstract: A process for making alternate S and Z twist plied yarn from individual singles yarns includes the steps of tensioning the singles yarns as they move in a path through the process, twisting the individual yarns in either an S or Z direction, stopping the forward movement of the yarn, then bonding the ply-twisted yarns at a node while applying twist, stopping the twisting operation, then repeating the procedure while twisting in the opposite direction.Type: GrantFiled: March 13, 1989Date of Patent: May 7, 1991Assignee: E. I. Du Pont de Nemours and CompanyInventors: Donald E. Hallam, Peter Popper, Harold F. Staunton, Paul W. Yngve
