Abstract
The instant invention is directed to an arrangement for forming a stable fiber web having high loft and high resilience. The arrangement includes a cabinet receiving opened and blended fibers connected with a fiber web forming chute which receives the opened and blended fibers from the cabinet. The forming chute includes a first and second wall and fiber contacting elements which assist in urging the fibers through and out an exit of the chute in an evenly distributed condition while forming the fiber web. The fiber contacting elements include a fiber inter-engaging device associated with at least one of the first and second walls, said inter-engaging device acting said outer fibers causing these fibers to inter-engage creating a stable outer surface over the fiber web.
Claims20
An arrangement for forming a stable fiber web having high loft and high resilience comprising:
- a cabinet receiving opened and blended fibers;
- a fiber web forming chute receiving said opened and blended fibers from said cabinet, said forming chute including a first and second wall and fiber contacting elements, which engages said fibers and assist in urging said fibers through and out an exit of said chute in an evenly distributed condition forming said fiber web;
- said fiber contacting elements include a fiber inter-engaging device associated with at least one of said first and second walls, said inter-engaging device acting on outer fibers adjacent to said at least one of said first and second walls to cause said outer fibers to inter-engage creating a stable outer surface;
- whereby,
- said fiber web will better maintain its formed configuration during transport to further processing.
A method of forming a fiber web including:
- providing a supply of opened fibers;
- delivering said fibers into a fiber web forming chute and moving said fibers through said fiber web forming chute forming said fibers into a fiber web;
- assisting movement of said fibers in said fiber web forming chute to be compressed forming said fiber web;
- providing fiber engaging members within said fiber web forming chute and causing said engaging members to move said formed fiber web through an exit of said fiber web forming chute and onto a conveyor for moving said fiber web to further processing;
- providing a fiber inter-engagement device along said chute and causing said fiber inter-engagement device to engage with outer fibers of said fibers forming said fiber web causing said outer fibers to inter-engage creating a fiber web having stabilized outer fiber web surface.
