A production system of a water-absorbent core. The supplying component thereof is configured to convey the fluffy cotton to the starting end of the transmission component, and the plurality of outlets of the supplying component for conveying the mixture of the fluff pulp and the hot-melt fibers to the transmission component are all located in the middle portion of the transmission component, the feeding port for conveying the super absorbent polymer to the transmission component and the outlets are arranged alternately along the transmitting direction of the transmission component, and each feeding port is located between the two outlets; the vacuum adsorption device can cause the mixture to be absorbed on the transmission component; the hot air penetration device performs hot air penetration treatment on the laminate; and the ultrasonic cutting device of the slitting mechanism is configured to ultrasonically cut the laminate after the hot air penetration treatment.

The present invention provides a method and apparatus for transporting a discrete element. A preferably rotatably driven vacuum commutation zone (or internal vacuum manifold), preferably internal to a preferably independently driven porous vacuum roll or drum is disclosed. The vacuum manifold applies vacuum through pores in the driven porous vacuum roll or puck in order to hold material against an external surface of the vacuum roll or puck. By independently controlling the vacuum commutation zone and the driven porous surface, unique motion profiles of the vacuum commutation zone relative to the driven porous surface can be provided. Micro vacuum commutation port structures are also disclosed.

A manufacturing method for a wearing item repeatedly executes: a step of, at a preceding pad, receiving and holding a distal end part of a continuous body to convey; a step of, at a following pad, catching up with the preceding pad; a both holding step of, at both of the preceding pad and the following pad, holding the continuous body; and a cutting step of cutting the distal end part of the continuous body to generate an individual workpiece on the preceding pad, and, in the both holding step, relative speeds of both of the pads are equal to each other, and both of the pads rotate at a non constant speed in at least part of a zone, the continuous body is fed from the feeder at the non-constant speed in response to a change in a speed of the pads that rotate at the non-constant speed.

Individual fibers of a material layer are pinched within adjacent coils of a spring in the present invention by a spring-like surface carried by a moving object such as a conveyor belt, rotating drum or rotating puck. The spring coils are slightly opened to accept the individual fibers. Next the spring coils are closed to carry and transport the web of fibers. At a deposition point, the coil springs, carried by a moving object such as a conveyor belt, rotating drum or rotating puck, are opened slightly, releasing fibers and depositing the web at a desired location.

A lamination system includes a film supply, a non-woven material supply, and a laminator. The laminator causes a film from the film supply to be laminated to a sheet from the non-woven material supply to establish a laminated sheet.

The transport method includes a speed varying step of varying speed of a first holding portion between a receiving position and a predetermined relay position by means of a speed change mechanism; a control step of controlling speed of a servo motor for driving rotation of second holding portions, such that speed of the second holding portions becomes a receiving speed at which the second holding portions is able to receive the absorbent body from the first holding portion at the relay position and becomes a predetermined transfer speed at a transfer position, and such that the second holding portions arrive at the relay position and at the transfer position at a predetermined cycle; and a speed changing step of changing the transfer speed while the cycle is maintained.
