Abstract:
METHOD FOR FORMING FILBROUS MATS OR INTERGRATED FIBROUS MASSES FOR A COLLECTION OF LINEAR BODIES BY PROVIDING A PLURALITY OF MAT-LIKE LAYERS WHICH MAY RESULT FROM THE DEPOSITION OF LINEAR BODIES ON A COLLECTING SURFACE, INTERLEAFING BINDER IN FILM FORM BETWEEN THELAYERS, AND ACTIVATING THE FILM TO DISPERSE THE BINDER AMONG THE INDIVIDUAL BODIES TO BIND THEM INTO AN INTERGRATED FIBROUS MASS, SUCH AS AIR FILTER MATS, INSLUATING MATS, OR THE LIKE.
Abstract:
Method and apparatus for distributing strands on a collecting surface aerodynamically. Embodiments of fluid nozzle and air foil members divert the strands after the strands have had a linear velocity imparted thereto to selected deposition points without touching the strands. A sweeping distribution of strands back and forth across a collection surface can be obtained by controlling the flow of fluid through the nozzle, controlling the air pressure between an air foil and a strand, by changing the angle of attack of an air foil, etc.
