Abstract
An apparatus for manufacturing bodily exudates absorbent structures has a rotating drum to convey a first continuous sheet, a feeding mechanism, a second conveying mechanism to convey a second continuous sheet and a sealing mechanism to join the first and second continuous sheets. The rotating drum is formed on its peripheral surface with depressions, leaving a non-depressed peripheral surface segment. Each of the depressions is formed in a central region with a central through-hole extending through each depression from an outer surface to an inner surface of the rotating drum. Within the rotating drum, a suction mechanism is installed to provide a suction effect directed from the outer surface toward the inner surface of the rotating drum so that the first continuous sheet is formed with a first concave region having been deformed along each depression and a second concave region having been deformed toward the central through-hole.
