  • Patent number: 9788475
    Abstract: An agricultural air cart assembly includes an agricultural air cart. The agricultural air cart includes independently controllable, first and second product metering systems that regulate the rates at which product flows from a storage compartment into corresponding first and second distribution lines. Independently controllable, rotatable fans are operatively connected to corresponding first and second distribution lines and are configured to generate optimized air flows in the first and second distribution lines which entrain and carry the product downstream toward corresponding row units at balanced pressures.

  • Patent number: 5481862
    Abstract: An open-end spinning device (1) of the type having a sliver opening device (30) and a pneumatically operated debris removal device (34) is disclosed. The opening cylinder housing (11) of the sliver opening device (30) has a debris discharge opening (15) and a cover element (9) mounted for restricted pivoting movement on a pivot shaft (10). A debris collecting element (16) is affixed to the cover element at a spacing (33) beneath the debris discharge opening and is connected to a suction device (8) which is a part of the spinning machine. The clear space (33) between the debris discharge opening (15) and the debris collecting element (16) assures that an auxiliary air flow (29), which is effective in the area of the debris discharge opening (15) to control the transport of fibers for the spinning process, is not affected by a suction air flow (28) applied at the debris collecting element (16).

  • Patent number: 5150502
    Abstract: A textile apparatus for sorting fibers according to their length. A fiber opening device loosens and separates raw textile fibers transported by an air flow created by an air blower along an air path. A fiber extracting device extracts fibers having an average length greater than or equal to a preselected length from the air flow to produce usable long fibers and creates a separated air flow containing usable short fibers having an average fiber length less than the preselected length for subsequent processing. The long fibers may be compacted into a fiber batt. The usable short fibers may be compacted into a fibrous batt or may be passed through further fiber extracting devices. The apparatus may include a batt former which includes a plenum into which fibers are delivered by the air propeller or blower.

  • Patent number: 5065479
    Abstract: A device for producing fibrous non-woven structures. The device includes a first duct for conveying an air flow over the lateral surface of a carding cylinder to remove the fibers from the carding cylinder and to convey them to a mobile forming surface. It further includes a second duct joining with the first, wherein a flow of compressed air is passed through the second duct to create in the first duct the air flow utilized in removing the fibers. In addition, an adjusting member is provided, faced to said first duct, at the downstream, end of said second duct, to adjust its outlet section.

  • Patent number: 5014396
    Abstract: In a method for manufacturing the fiber-containing article, the discontinuous fibers, intermingled with fibers serving as a binder, are couched into a fiber mat in such a manner that the discontinuous fibers are advanced into contact with an air flow which carries them up to a conveying level where the fibers become randomly directed and the fiber-carrying air flow is passed through this level.

  • Patent number: 4258455
    Abstract: A process and mechanism for the dry screen forming of fibers to attain a dispersion in air of substantially individual fibers from which a fibrous sheet is formed. Fibrous nits, pills and flocs are removed from the dispersion by rolling the nits, pills and the like into elongated shapes as they pass a fiber screening member and carrying the elongated fibrous bodies from the dispersion of fibers and away from the sheet forming area for the fibers. The mechanism includes a fiber screening member, a fiber receiving member on which the sheet is formed and a foraminous member which rolls the nits, pills and the like between it and the fiber screening member as the air dispersion of fibers passes toward the fiber receiving member.

  • Patent number: 4223423
    Abstract: A cotton lint cleaner having a number of new and unique features. The lint cleaner uses a common air stream laden with cotton to be cleaned through a moving screen and then through feed rollers to a cylindrical saw, where a centrifugal air flow doffing impeller doffs the cleaned cotton from said saw, for discharge from the device. Special spring biased feed bars are also a part of this invention. Additional features include special grid bars, special settling and collection chambers, guide vane structure, a rotating paddle wheel vacuum lock, an adjustable vacuum valve control, and filtering and discharging of the exhaust air flow through a cover over the operating drive for the over-all machine in order to exclude contamination from the outside air of said drive components. Special tension mountings for the grid bars are also disclosed.

  • Patent number: 4074393
    Abstract: In dry forming a layer of fibers, the fibers are conveyed by carrier air to a distributor housing having a perforated bottom wall through which the fibers pass downwards on to a foraminous forming surface connected on its underside to a suction box. The invention ensures that the fibers pass from the distributor to the forming surface under the influence of suction and gravity alone so as to provide a layer of more uniform depth than hitherto obtained by dry forming.
