ABSTRACT:
A soft, loosely compacted mat of fibers is continuously formed atop a traveling conveyor. The fibers are deposited on top of the screen from an air-fiber flow within a suitably sized conduit having the same width as the desired width of the mat. A fiberizer is upstream from the mat-laying station and serves to fiberize sheets of incoming fiber. A plurality of sheets can be fiberized and as they are fiberized, the flow is entrained with air with differential pressures throughout the flow path from the fiberizing station to the conduit and mat-laying station. The structure of the fiberizer allows fiber sheets to be fiberized and then directs the fibers toward an adjustable diverging portion of the fiberizer shell from where the air-fiber mixture flows toward the mat-laying station. Variable mat widths can be formed by varying the conduit width and by varying the lateral dimension of the diverging portion of the fiberizer shell.
