A web (110) including a fibrous material and superabsorbent material is fed to a knife (120). The web (110) has a first surface, a second surface, a first side edge and a second side edge. The knife (120) cuts the web (110) into individual absorbent members having a pair of opposing cut ends. The individual absorbent members have a first surface, a second surface, a first side edge, a second side edge, a first end edge and a second end edge, with the first and second end edges corresponding to the cut ends. A flowable superabsorbent movement obstruction agent (122) is applied to the cut ends.
