Patent number: 6195842Abstract: 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.Type: GrantFiled: December 3, 1996Date of Patent: March 6, 2001Assignee: E. I. du Pont de Nemours and CompanyInventors: Kenneth Stephen Freund, Andrew James Giles, Todd Arden McCoy, Lyles Howard Sowell, Phillip Osborne Staples, Leonard Ray Tucker, James Stephen Bailey

Patent number: 6195844Abstract: A carding machine or other web production device [(1)] supplies a crosslapper [(2)] with two elementary webs [(15a, 15b)] constituting a lappable web [(16)] which is deposited in a reciprocating manner on a transverse output belt [(26)]. In the device [(1) means of] adjustment of the speed of rotation of doffers [(13a, 13b)], of condensers [(17, 18)], of detachers [(19a, 19b)], of the drum [(4)] and/or of the feeder [(7)], and/or [means of] adjustment of the drum-doffer spacing affect the weight per unit area of the elementary web produced taking account of the weight per unit area desired at each point in the width of the fleece [(67)] to be formed on the output belt [(26)]. There is determined the delay length exhibited by each elementary web cross-section undergoing the adjustment of weight with respect to the section of lappable web in the process of being deposited.Type: GrantFiled: December 5, 1997Date of Patent: March 6, 2001Assignee: AsselinInventors: Bernard Jourde, Jean-Christophe Laune, Robert Jean

Patent number: 6195845Abstract: A fiber web is formed by the airlay technique on a web forming and transport surface by dispersing and projecting individualized fibers onto said surface by means of a flow of air, and the fibers are subjected to a carding operation prior to being inserted into the flow of air. According to an essential characteristic of the invention, action is taken on the fiber feed rate by means of one or more regulator systems between the carding operation and the insertion of the fibers into the air flow so as to make said fiber feed rate more regular. In a preferred variant of the invention, a regulator system comprises at least a combing cylinder which is designed to be rotated to have a circumferential speed that is strictly less than that of the carding cylinder and that rotates in a direction of rotation that is opposite to that of the carding cylinder, and that is coated on its periphery with a covering whose teeth or spikes point backwards, i.e. in the opposite direction to its direction of rotation.Type: GrantFiled: April 14, 1999Date of Patent: March 6, 2001Assignee: ThibeauInventors: Jean-Louis DuPont, Xavier Catry, Marc Brabant
