Abstract
A process and an apparatus for distributing short fibrous material onto a horizontally travelling sheet. A disintegrated short fibrous material is fed into a hopper comprising a substantially hollow casing disposed above the travelling sheet and having a fiber discharge port at a lower portion with of a side wall on the downstream side. A mesh having a width equal to or larger than that of the travelling sheet and having partitions provided thereabove for suppressing the transverse movement of the fiber is provided below the hopper and with a spacing above the travelling sheet. The mesh screen is horizontally and transversely vibrated to distribute the fiber therethrough onto the travelling sheet, whereby the fiber is uniformly distributed without causing pilling even if it is fed at a considerably small rate.
