Soft film

Abstract

The invention relates to a method of making a film, and to a die for making the film. The fluid die includes a fluid feed manifold connected to a housing having positioned therein at least one fluid feed channel in fluid communication with the fluid feed manifold. The housing also includes at least one profiling block within the fluid feed channel.

1 .- 25 . (canceled)  
     
     
         26 . A method of making a film comprising: 
 pressing a precursor film against a surface of a screen provided with indentations;    passing successive portions of the precursor film under a fluid die;    spraying a liquid from the fluid die onto the film to form protuberances, wherein a fluid pressure at a leading wall of the fluid die is greater than the fluid pressure at a trailing wall of the fluid die.    
     
     
         27 . The method of  claim 26 , wherein the precursor film comprises polyethylene.  
     
     
         28 . The method of  claim 26 , wherein the protuberances comprise apertured protuberances.  
     
     
         29 . The method of  claim 26 , wherein the liquid pressure at the leading wall of the fluid die is sufficient to aperture the film.  
     
     
         30 . The method of  claim 26 , wherein the fluid die comprises at least two profiling blocks.  
     
     
         31 . The method of  claim 30 , wherein the profiling blocks are adjustable.  
     
     
         32 . The method of  claim 26 , wherein the fluid die comprises at least two fluid feed channels.  
     
     
         33 . The method of  claim 32 , wherein the fluid die comprises at least four fluid feed channels.  
     
     
         34 . The method of  claim 26 , wherein the fluid feed channel of the fluid die is adjustable to adjust the fluid flow through the feed channel.  
     
     
         35 . The method of  claim 26 , wherein the fluid die comprises two profiling blocks, each profiling block have a substantially different shape.  
     
     
         36 . The method of  claim 35 , wherein one of the profiling blocks is triangular, and one of the profiling blocks is a pentagon.  
     
     
         37 . The method of  claim 30 , wherein the two profiling blocks have substantially the same shape.
