ABSTRACT:
There is provided a process for the continuous separation of discarded hygiene articles into their components, namely flock and/or cut absorbent materials on the one hand and sheet coverings on the other comprising first tearing the discarded hygiene articles into large pieces and then conducting the pieces over an oscillating sieve surface, preferably over an oscillating sieve device having decreasing mesh widths with the smallest mesh width being so selected that the flocculent and/or cut absorbent material still can fall through while the large pieces of torn covering are always carried off as sieve residues.
