ABSTRACT:
The present invention relates to methods and apparatus for the controlled placement of a shear-thinnable polymer composition into a moving web. The controlled placement is preferably performed by applying the polymer composition onto a surface of a moving web, shear thinning the composition and placing it into the web, and curing the polymer composition. A preferred apparatus includes one or more process heads that has mounted thereto a rigid knife blade for engagement with the moving web. The knife blade is movable vertically and rotationally. The process head is also movable horizontally along the path of the moving web. A plurality of macro and micro tension zones are established and are monitored for controlling the apparatus and process. Additional measurements of web density, micro porosity, placement of an internal layer of polymer within the web, analysis of elements on the treated web, and the size of the polymer bead applied to the moving web are measured for controlling online the apparatus and the process of this invention. This method and apparatus produces webs that either has some of its structural elements encapsulated by the polymer composition while at least some of the interstitial spaces of the web are open; or has an internal layer extending through the web in a direction generally spaced from at least one major surface thereof; or has both encapsulated structural elements and an internal layer of polymer composition.
