With Lacteal Fluid Receptor Or Shield Patents (Class 450/37)
  • Patent number: 4738745
    Abstract: Maternity pads for absorbing excess mother milk spilled out are manufactured in a single assembly line, in which rolls of absorbent materials drawn out forward and stacked one upon another are die-cut into disks, which are then sent forward and placed onto a web of waterproof paper traveling ahead, while being covered by a web of covering material traveling in the same direction. The outside of the disks of absorbent materials are sealed and die-cut to obtain disks with the absorbent materials wrapped up in the waterproof paper and covering material. The disks are then transported to a shaping unit where they are formed into bowl-shaped pads by means of pairs of male and female molds. The finished maternity pads are removed from the line by a discharge means.
