Abstract:
Methods and apparatus (40) to neutralize the charge on a moving web (42) by splitting the field present on the web (42). One portion of the field is removed by a grounded element (55a, 55) proximate to, and optionally contacting, one side of the web (42). Proximate the opposite side of the web, the apparatus includes an ion source (57a, 57b, 57c), which provides ions to the web (42) to neutralize the charge remaining on the web (42), and a second grounded element (50a, 50b, 50c) positioned between the ion source (57a, 57b,57c) and the web (42). The methods provide a web (42) that is net neutralized and is also dual-side or bipolar neutralized.
Abstract:
Described herein is a method of adjusting a slot die is provided, the slot die including an applicator slot extending along a width of the slot die, wherein the applicator slot is in fluid communication with a fluid flow path through the slot die, at least one of a group consisting of: a choker bar and flexible die lip, and a plurality of actuators spaced along the width of the slot die, each actuator operatively coupled to the choker bar or flexible die lip to adjust a cross-sectional height of a fluid flow path at its respective location to provide a local adjustment of fluid flow through the applicator slot. The method includes measuring thickness values of an extrudate provided from the applicator slot; mapping the thickness values to a corresponding position along the width of the slot die; executing a data compression of the extrudate thickness values to obtain a residual matrix representing the deviation of the measured thickness values from desired thickness values; and adjusting the position of one or more of the plurality of actuators based on the residual matrix to obtain a corrected shape for the choker bar or flexible die lip.
Abstract:
Provided are methods of operating a slot die having an applicator slot extending along a width of the slot die, wherein the applicator slot is in fluid communication with a fluid flow path through the slot die, and at least one of a group consisting of: a choker bar and a flexible die lip. The choker bar or the flexible die lip shape can be manipulated by applying, with a force application mechanism, forces that are generally parallel to the width of the slot die. Further provided are methods of operating and purging a slot die, where at least a portion of the applicator slot is blocked with one or more deckles to reduce an effective width of the applicator slot.
Abstract:
A method of adjusting a slot die is provided, the slot die having an applicator slot extending across a width of the slot die, wherein the slot die comprises opposed first and second slot die surfaces, and wherein the applicator slot is in fluid communication with a fluid flow path through the slot die. The slot die includes first and second adjustment mechanisms operatively coupled to the first and second slot die surfaces, respectively. The method includes assigning a target setting for the first adjustment mechanism based on a pre-selected cross-web profile for an extrudate; with that target setting, determining a slot height profile corresponding to a plurality of locations along the opposed first and second slot die surfaces; predicting, with a controller, a set of discrete settings from a plurality of discrete settings based on both the slot height profile and the pre-selected cross-web profile, the prediction based on a known correlation between the set of discrete settings and a cross-web profile of the extrudate; and setting a position for each of a plurality of actuators coupled to the second adjustment mechanism according to the predicted set of discrete settings.

Abstract:
Methods of altering charge on a dielectric material involve application of an at least weakly conductive liquid to at least a portion of the dielectric material. The liquid is then at least partially removed from the dielectric material leaving a substantially uniform electrostatic charge on at least the portion of the dielectric material. Some methods provide a dielectric material that is both net neutral and completely neutral. Other methods generate a charge pattern that is used for subsequent processing.
