US Patent:

56067763, Mar 4, 1997

Filed:

Nov 7, 1995

Appl. No.:

8/550551

Inventors:

Kenneth S. Freund - Hendersonville TN
Andrew J. Giles - Joelton TN
James S. Bailey - Arlington VA

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

D01G 1540

US Classification:

19105

Abstract:

This invention relates to the creation of a different styled batt from tufts of fiber for delivery to textile machinery. In particular, the batt formed in the style of this invention is particularly suited for delivery to a carding machine. Carding machines are able to more fully utilize fiber processing capacity with lower risk of becoming overloaded because the tufts are less able to be pulled out of the batt intact but are held back allowing for the lickerin roll or other feed arrangement to pull fiber out of the batt in a more continuous and uniform manner.

International Classification:

B01D 35143

US Classification:

210741

Abstract:

A method to determine differential filter pressure caused by filter pluggage in a high pressure liquid system operated by a computer-operated control valve without the need for a pressure sensor coupled to the filter by corerlating the percent the control valve is open with the differential pressure of the filter. A signal is provided when the percentage of time the control valve is open exceeds a predetermined time and the filter is replaced in response to the signal.

International Classification:

D01G 2500

US Classification:

19304

Abstract:

This invention relates to improved aerodynamics in dry fiber web forming machines and particularly to airlays which form high quality webs. The invention includes a disperser roll for feeding fibers into the air stream and a second roll opposite to the disperser roll for balancing the disruptive effects of long stationary walls and rotating members in the air duct. In one alternative arrangement of the invention, the fibers are also fed to the air stream by a second disperser roll opposite the first disperser roll.

International Classification:

B05B 114

US Classification:

239590

Abstract:

An apparatus for distributing fiber from a carding machine to an airlay wherein the apparatus comprises a system of ducts or conduits for controlling air flow having a curved top wall and a curved bottom wall that define a converging passageway and the distance between the walls is defined by an exponential equation.

Assignee:

E. I. du Pont de Nemours and Company - Wilmington DE

International Classification:

D01B 100

US Classification:

19 975

Abstract:

A device and process for dividing a pneumatic flow of fiber into a plurality of streams of pneumatically-conveyed fiber which aid in distributing the fiber more uniformly across an area such as a fiber bin.

D01G 2500

US Classification:

19106R

Abstract:

A process of feeding carded fiber to an airlay and particularly to combining carding technology with airlay technology. A carding machine portion is arranged to card fiber while a disperser-roll in the airlay portion picks the individualized carded fibers from a tool bed roll and centrifugally doffs them into an air stream. As such, airlays will be able to handle longer fiber lengths which conventional airlay equipment is unable to handle or satisfactorily open up. Further, an improved process for doffing fiber from a airlay machine and particularly centrifugally doffing fiber from a carding machine.
