摘要： An apparatus that can measure both haze and clarity on a web moving at conventional manufacturing speeds. The apparatus uses an integrating sphere and a novel mirror arrangement. With this arrangement, the invention can utilize a calibration curve created using known samples over the range of measurement desired to convert in real time, and the response of two photo detectors that measure the wide and low angle scattering signals, to deduce the desired optical property values. This approach significantly increases the speed and response of sensor and enables either on-line single point or full web scanning for uniformity measurement and control.

摘要： Provided are methods of adjusting a slot die. The slot die includes 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 slot or choker bar height profile 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 measured thickness values to a corresponding position along the width of the slot die; executing a data compression of the measured thickness values to obtain a residual vector representing deviation of the measured thickness values from desired thickness values; and adjusting a position of one or more of the plurality of actuators based on the residual vector to obtain a corrected shape for the choker bar or flexible die lip. The adjustment includes using the residual vector to predict a degree of ringing for a proposed set of actuator positions and then applying a ringing constraint to obtain a revised set of actuator positions that reduces the degree of ringing relative to the predicted degree of ringing.

摘要： A system comprises a slot die including an applicator slot extending about a width of the slot die, wherein the applicator slot is in fluid communication with a fluid flow path through the slot die, and a plurality of actuators spaced about the width of the slot die. Each actuator is operable to adjust a cross-directional thickness of the fluid flow path at its respective location to provide a local adjustment of fluid flow through the applicator slot. The system further comprises a controller configured to set the position of each actuator according to one of a plurality of discrete settings for operation of the slot die. The controller is further configured to predict a set of discrete settings corresponding to a preselected cross-web profile for an extrudate based on a known correlation between the set of discrete settings and the cross-web profile of the extrudate.

摘要： 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.

摘要： 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.
