Patent number: 10782068Abstract: The apparatus (100) comprises several stations for treating fabric (10). For example, a cleaning station (20) is provided that is arranged to remove loose debris from the fabric and move the fabric in a continuous motion through the cleaning station. A treatment station (40) is then arranged to receive the fabric from the cleaning station and to transfer treatment fluid to the fabric in a treatment zone. Finally, a drying station (50) is arranged to receive the fabric from the treatment station and to dry the fabric in a drying zone. Advantageously, the treatment station is arranged to transfer the treatment fluid by spraying the treatment fluid under pressure onto a side of the fabric.Type: GrantFiled: November 4, 2016Date of Patent: September 22, 2020Assignee: Technijet Digital LimitedInventor: David McFarlane

Publication number: 20110120588Abstract: First warp yarns and second warp yarns are each interwoven with weft yarns to produce a one-layer, lightweight, stretchable fabric. The first warp yarns include stretchable yarns that are activatable to achieve a contracted state, and the second warp yarns include non-stretchable yarns. The first warp yarns may include a stretchable core yarn with non-stretchable wrap yarn wrapped around the stretchable core yarn. The first warp yarns may be in an alternating arrangement with the second warp yarns. When the yarns are woven together, the first warp yarns are in an extended state and the second warp yarns are in an unbunched state. The fabric then undergoes a finishing procedure during which the first warp yarns are activated to achieve a contracted state. The second warp yarns thus achieve a bunched state, and the resulting fabric is stretchable in the warp direction.Type: ApplicationFiled: November 24, 2009Publication date: May 26, 2011Inventor: Yaakov Shteiyer

Patent number: 6820655Abstract: The invention relates to an improvement in the art of loom and weaving room conditioning, in which the necessary moisture required by the yarn to perform best in the loom is metered exactly and directly on the yarn, whereby yarn breakage is reduced and weaving air room humidity can be lowered, thereby improving human comfort. Lint and dust generated by the weaving process are removed at their source so air contamination is lowered, improving hygienic conditions and reducing air filtration requirements. Heat generated by the weaving process is partly removed by water-cooling the lubricating oil, thereby reducing the weaving room heat load. Large peripherally located air conditioning units are replaced by smaller units, distributed over or under the roof of the room, each serving the area of 4-24 looms.Type: GrantFiled: March 22, 2002Date of Patent: November 23, 2004Inventor: Hans Adolf Beeh

Patent number: 6164341Abstract: In a weaving machine, the shuttles of the weaving machine are transferred over and across the warp threads of the machine. The method and apparatus have the object of preventing factors which adversely affect the weave result from occurring at high shuttle speeds. One or more air or gas streams (flows) are conveyed from the undersides of the warp threads and upwardly via the warp threads to their upper sides. With the upwardly conveyed air or gas stream, each shuttle is given a lifting movement which prevents burn damages, deformations and wearing of the warp threads due to a high shuttle speed.Type: GrantFiled: November 19, 1997Date of Patent: December 26, 2000Assignee: Texo ABInventor: Bo Lindblom

Patent number: 4901766Abstract: The warp threads in a loom are cooled, in order to prevent damage to the warp threads due to heat generation by the contact between the warp threads and loom components. Such contact can generate temperatures of 50.degree. to 80.degree. C. due to thread friction and thread shifting, whereby capillary breaks of the warp threads are caused so that continued weaving becomes impossible. Such heat generation is avoided by cooling the loom components which contact the warp threads. A cooling fluid is circulated through the warp thread contacting components. The cooling fluid may be a liquid or a gas. At least the leasing or fulling mill is cooled in this manner. The cooling is preferably carried out to such an extent that condensation water forms on the surfaces of the cooled components, whereby the condensation water acts as a lubricant for the warp threads.Type: GrantFiled: November 23, 1988Date of Patent: February 20, 1990Assignee: Lindauer Dornier Gesellschaft mbHInventor: Valentin Krumm

Patent number: 4489760Abstract: Wide woven fabric having dipped and treated cords is made by first connecting warp cords of relatively strong material in at least two narrow sheets. The narrow sheets are dipped and treated after which they are positioned in loom letoff rolls adjacent a loom where they are joined to form a wide fabric having a width greater than the width of either of the narrow sheets. The warp cords from the narrow sheets are guided from the letoff rolls into the loom and during the process the narrow sheets may be run through a cord separating apparatus to separate the warp cords. The warp cords may be woven in the loom with a dipped and treated weft cord to provide a wide reinforcing sheet with a heavy woven construction having a width greater than the width of any one of the narrow sheets.Type: GrantFiled: August 15, 1983Date of Patent: December 25, 1984Assignee: The Goodyear Tire & Rubber CompanyInventors: Barry W. Long, David H. Roush, deceased

Patent number: 3952552Abstract: There is disclosed a mechanism for dyeing yarns as they are fed from their cones into a knitting machine. Each yarn passes through a container in which there is a liquid dye of a color selected for that particular yarn. Although a quick-drying dye is used, to insure that each yarn is completely dried prior to its reaching a respective knitting needle, a jet of air is directed against each yarn as it exits from its respective dye container.Type: GrantFiled: September 29, 1972Date of Patent: April 27, 1976Assignee: C.J.I. Industries, Inc.Inventor: Allan Rozner
