Patent number: 7774903Abstract: A high speed roller gin for seed cotton with variable length fibers has its components defined in accordance with the formula RKBS<(2SR-2MD)*RKSS/GRSS where, the rotary knife circumferential blade (RKBS) spacing is less than 2-times the seed release distance from the tip of the stationary knife (SR) minus 2-times the minimum distance the seed surfaces are allowed to approach the tip of the stationary knife (MD) multiplied by the rotary knife surface speed (RKSS) and divided by the ginning roller surface speed (GRSS). A seed cotton infeed slide further limits the exposure of the seed directly against the tip of the stationary knife to reduce the ginning of the undesirable short fibers. A process for using such gins is also disclosed.Type: GrantFiled: August 16, 2006Date of Patent: August 17, 2010Assignee: Lummus CorporationInventor: Donald Van Doorn

Patent number: 7481158Abstract: An apparatus and method for producing a bale of lint cotton fiber by pre-compressing each consecutive charge of fiber fed from the lint slide to a predetermined and uniform density. The apparatus includes a supply chamber predisposed with both vertical and horizontal platens driven by independent hydraulic cylinders. The movement and cycling of the platens is such that measured charges of fibers are presented to a vertical tramping device at consistent and uniform density. The tramping device, consisting of a platen driven by two hydraulic cylinders, packs each charge into a stationary box, one charge after another. This process continues until the desired bale weight is reached. The tramper cylinders are driven to a predetermined pressure setting during the tramping phase of each stroke cycle (extension) resulting in uniform compression (density).Type: GrantFiled: December 19, 2006Date of Patent: January 27, 2009Assignee: Lummus CorporationInventors: Royce H. Gerngross, Joe W. Thomas

Patent number: 6698066Abstract: A method and apparatus for conditioning a fibrous material. The conditioning arrangement includes a moisturizing chamber having two series of opposed rollers arranged to accept a fiber batt into a pressing space therebetween. The pressing space tapers from a batt entrance toward a batt exit. This tapered configuration is affected for compressing a fiber batt as it is rolled therethrough. As illustrated, before entering the conditioner, the cotton batt has a greater thickness than after compaction and processing through the moisturizing chamber. A moisture infusion assembly is provided within the moisturizing chamber and has an air distributor configured to dispense moisture laden air adjacent to a fiber batt being processed through the pressing space. An air collector is configured to pull exhaust air away from the fiber batt being processed through the pressing space.Type: GrantFiled: November 16, 2001Date of Patent: March 2, 2004Assignee: Lummus CorporationInventor: Keith Latham
