Method and apparatus forming a fiber web

Abstract

A fiber web forming apparatus which utilizes a fiber mixing chamber which in operation receives fibers from a plurality of sources along with a chemical agent, generally a bonding agent. The mixing chamber acts to further open and blend the fibers and also to blend the chemical agent with the fibers before the forming of the fiber web.

What is claimed is:  
     
       1. In a fiber web forming apparatus having at least one vertically disposed fiber feed chute feeding fibers into a mixing chamber, a fiber web forming chute, and a chemical agent distribution system comprising: 
       a supply unit for said chemical agent;  
       a chemical agent feed chute opening into said mixing chamber, said chemical agent feed chute being vertically disposed and arranged adjacent said at least one fiber feed chute, said chemical agent feed chute including an upper shaft and a lower shaft;  
       a feed for receiving said chemical agent from said supply unit and delivering said chemical agent into said chemical agent feed chute and subsequently into said mixing chamber; wherein  
       said mixing chamber acts to blend said fibers and chemical agent before passage of said fibers and chemical agent into said fiber web forming chute.
