초록 ▼

A system for forming an air laid web of fibers and/or particles on a moving foraminous carrier. Fibers and/or particles are blended, and while supported in an air stream, introduced into a distributor unit. The distributor unit includes a rotatable cylinder formed with classification apertures of a predetermined shape, number, and size as specifically related to the types of fibers and/or particles utilized. A rotatable shaft with radially extending wire-like members agitates the fibers and/or particles and throws them outwardly through the apertures. Downwardly directed air flow transports the refined fibers and/or particles so as to form a homogeneous, still further refined, web on the surface of the carier. A variety of adjustments and alternations can be made to the system and its components to control the composition and thickness of the end product, and to attain maximum capacity for any combination of fibers and/or particles.

A process for forming an air laid web of predetermined characteristics comprising the steps of: (1) forming a stream of roughly graded material of first loose fibers and at least one of (a) second loose fibers (b) particles, (2) directly and controllably introducing said stream of material into a mixing zone with air to produce an air-borne stream of said roughly graded material; (3) forming a recirculating air-borne stream of said roughly graded material and said stream includes some clumps of fibers, called nits; (4) causing said nits to be removed from said recirculating stream at at least two spaced locations; (5) introducing said air-borne stream of step (2) into said recirculating stream of step (3); (6) causing at least a portion of said recirculating stream of roughly graded material to rotate in one direction; (7) causing an internal portion of said recirculating stream to rotate in an opposite direction to that of step (6); (8) removing from the perimeter of said recirculating stream roughly graded material at the general location of said contrarotation, material of a predetermined size and shape to be a first finely graded material; ((9) causing said first finely graded material to become a directionalized air-borne stream; (10) providing a translating zone of a portion of said first finely graded material where said translation is in a direction transverse to said directionalized air-borne stream of step (9); and (10) providing a second fine grading of said material in said air-borne stream by arresting predetermined sizes and shapes of said first finely graded material in said translating zone to provide said web of predetermined characteristics as a second finely graded material web. Apparatus for forming an air laid web of predetermined characteristics material comprising: supply means forming a stream of roughly graded material of first loose fibers and at least one of (a) second loose fibers (b) particles and for mixing the roughly graded material with air to produce an air-borne stream thereof; distributor means forming a recirculating air-borne stream of the roughly graded material adapted to receive the air-borne stream from said supply means, said distributor means including tumbler means causing at least a portion of the recirculating stream of roughly graded material to rotate in one direction and agitating means causing an internal portion of the recirculating stream to rotate in an opposite direction to that of said tumber means, said recirculating stream to have clumps of fibers, called nits; said tumbler means being a first fine grading means having a plurality of classification apertures extending therethrough being of a predetermined shape, number, and size as specifically related to the types of the roughly graded material desired in said webs of predetermined characteristic introduced to said distributor means; said agitating means adapted to cause flow through the classification apertures of a first finely graded material; a plurality of nit removal conduits communicating with said distributor means at spaced locations with reference to said recirculating air-borne stream to remove nits from said stream; air flow producing means causing the first finely graded material to become a directionalized air-borne stream; and a foraminous carrier movable in a direction transverse to the directionalized air-borne stream being arranged to be a second fine grade means for arresting predetermined sizes and shapes of the first finely graded material resulting in a translating arrested web of material of predetermined characteristics.
