  • Patent number: 6604926
    Abstract: In an apparatus for and method of producing absorbent pads from a flock-air mixture which is fed through a feed conduit to a shaping recess carrier to form the respective absorbent pad, the carrier rotates or circulates in a predetermined direction of operation. For excess air in the region of the flock-laying device is to be sucked away in a simple fashion without adversely affecting the process of shaping the absorbent pad, the feed conduit feeding the flock-air mixture to the carrier is branched into at least first and second conduits, the first conduit carrying a first partial flow of the mixture and the second conduit carrying a second partial flow thereof. The first and second conduits are directed on to the carrier in such a way that the second partial flow meets the carrier substantially downstream of the first partial flow in the direction of operation of the carrier.
