Several embodiments of apparatus for producing disposable absorbent personal articles are disclosed. According to one embodiment, apparatus is disclosed for depositing superabsorbent polymer powder on a portion of a fluff mat in a given concentration greater than zero and a second, different concentration of superabsorbent polymer powder on another portion of a fluff layer, so that there is a heavier concentration of super absorbent polymer in a target area than in areas adjacent the target area. Such apparatus has a dosing cylinder with a discontinuous outer cylindrical surface which has a pattern of first dosing depressions adjacent to a pattern of second dosing depressions. The dosing cylinder is rotated through a polymer powder hopper and powder received in the first and second depressions is sequentially discharged from the hopper and deposited on a fluff substrate in alternating areas of high powder concentration and low powder concentration. Discreet sections of the fluff containing superabsorbent are cut and incorporated in personal absorbent articles and apparatus for marking such articles is disclosed so that the mark gives an indication as to whether or not the apparatus is operating synchronously or not.
