Patent ID: 7325277

Claim:
An arrangement for forming a fiber web in which fibers remain evenly distributed throughout and compacted on both the upper and lower surfaces of said web comprising: a housing receiving opened and blended fibers; a fiber web forming chute receiving said opened and blended fibers from said cabinet, said fiber web forming chute having an upper and a lower wall which are driven to assist with the movement of the fibers through and out an exit end of said web forming chute; individual drive members driving said upper and lower walls at individually selected speeds depending upon the fiber volume needed; a packing member adjacent said exit end engaging and compressing said emerging fiber web to a desired density and height; a sensor carried by said packing member and associated with said drive members; an air flow system passing a flow of air into said forming chute entrance, said air flow engaging with said fibers during passage thereof through said forming chute, said air flow system including an air removal system in said upper wall of said forming chute and in said packing member, said air removal system causing said air to exit upwardly through said fiber web and out through said upper wall and said packing member as said fiber web passes through and out of said forming chute and beneath said packing member; wherein, said air flow engaging with said fibers maintains said fibers evenly distributed between upper and lower surfaces of said web during formation thereof and said sensor is activated by the position of said packing member to control the rates of said drive members in accordance with the desired height and density of said fiber batt being formed.
