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.
