Patent number: 9581531Abstract: A yarn entanglement strength tester includes first and second rolls that apply incrementally increasing elongation levels on a yarn in order to remove entanglements from the yarn. The yarn entanglement strength tester also includes a third roll, where the second and third rolls apply a constant tension on the yarn which enables optimum diameter measurements of the yarn by a camera. The camera captures images of diameters of the yarn after each of the incrementally increasing elongation levels is applied to the yarn. The yarn entanglement strength tester further includes a computing device that controls operation of the camera and the first, second, and third rolls, and determines an entanglement strength of the yarn based on the captured images of the diameters of the yarn after each of the incrementally increasing elongation levels is applied to the yarn.Type: GrantFiled: January 31, 2012Date of Patent: February 28, 2017Assignee: Lawson Hemphill, Inc.Inventors: Dean A. Ross, Filiz Avsar, Kendall W. Gordon, Steven Leary

Patent number: 6741726Abstract: A system or method for electronically simulating fabrics to assist in grading yarn and fabric qualities, in which the diameter or other qualities of one or more yarn samples along the total length of the samples is measured, and representations of the measured yarn qualities are evaluated in a fabric pattern to assist evaluation of the effects of the yarn quality variations on fabric which potentially would be produced from the sampled yarn.Type: GrantFiled: September 6, 2000Date of Patent: May 25, 2004Assignee: Lawson-Hemphill, Inc.Inventors: Avishai Nevel, Kendall W. Gordon, Jr., David Bonneau

Patent number: 5875419Abstract: A computer-controlled device for determining relative yarn hairiness. Yarn is moved past a light source to create a yarn shadow, and an imaging device captures the yarn shadow. The imaging device includes a number of separate, closely-spaced light sensing elements, each with an output level related to the amount of light shining on the element. A selected sensing element output level is established as indicative that an element is blocked by the yarn. The width of a number of closely-spaced portions of the yarn is determined, at two different selected sensing elements output levels, to distinguish the yarn hairs from the yarn core.Type: GrantFiled: November 13, 1995Date of Patent: February 23, 1999Assignee: Lawson-Hemphill, Inc.Inventors: Avishai Nevel, Kendall W. Gordon, Jr., Steven Leary

Patent number: 5791542Abstract: A system for moving yarn under substantially constant tension, including a translationally-fixed pivoting device, having a neutral position, for applying tension to the yarn, and a variable-speed yarn drive for moving the yarn across the pivoting device. The rotational position of the pivoting device is determined in relation to its neutral position, and in response, the speed of the yarn drive is altered to move the pivoting device closer to its neutral position for maintaining a relatively constant tension on the yarn.Type: GrantFiled: March 27, 1997Date of Patent: August 11, 1998Assignee: Lawson-Hemphill, Inc.Inventors: Itzchak Porat, Kendall W. Gordon, Jr., Avishai Nevel, David Bonneau

Patent number: 5761264Abstract: A method of automatically determining the number of filaments making up a synthetic yarn, or other yarn such as staple natural fibers comprising removing a small cross-section of the yarn to create a plurality of small filament pieces, and automatically counting the small filament pieces to determine the number of filaments in the yarn.Type: GrantFiled: December 2, 1996Date of Patent: June 2, 1998Assignee: Lawson-Hemphill, Inc.Inventors: Avishai Nevel, Kendall W. Gordon, Jr.

Patent number: 5420802Abstract: A system and method for testing yarn altering devices in which the yarn is moved under precision yarn controls such as speed and tension, and then through the yarn altering device. Downstream of the yarn altering device the yarn is imaged, and from the image the widths of closely-spaced portions of the yarn are determined to establish the effect on the yarn of the yarn altering device.Type: GrantFiled: August 17, 1993Date of Patent: May 30, 1995Assignee: Lawson-Hemphill, Inc.Inventors: Avishai Nevel, John B. Lawson, Kendall W. Gordon, Jr.

Patent number: 5319578Abstract: A yarn profile analyzer and method in which the yarn is moved under substantially constant tension through an imaging area including a light source and a spaced light sensing array. The width of closely spaced portions of the yarn passing through the imaging area is then determined from the array output, and the widths are stored and then analyzed for a variety of parameters.Type: GrantFiled: September 24, 1992Date of Patent: June 7, 1994Assignee: Lawson-Hemphill, Inc.Inventors: John B.
