A continuous web processing device including a folding unit that extends in a conveyance direction. The folding unit has a central guide that comes into contact with the bottom of the crotch part of an absorbent article being processed, a pair of side guides that come into contact with the front waistline portion and the rear waistline portion of the absorbent article, and a superimposing roller that superimposes the front waistline portion and the rear waistline portion one on the other. A spacing between the pair of side guides becomes narrower in the downstream conveyance direction. Ends of the side guides are located further upstream than an end of the central guide. The superimposing roller superimposes the front waistline portion and the rear waistline portion of the absorbent article one on the other downstream from the side guides.

Continuous web processing device

A transfer device equipped with a rotating body having multiple workpiece holding units that support a holding surface holding a continuous sheet member through suction that faces outward in the radial direction of the rotation body. Between adjacent workpiece holding units, arranged in the direction of rotation, the device is equipped with bed knives that produce single sheets by sandwiching and cutting the continuous sheet member in combination with a cutter member arranged to face the outer surface of the rotation body. The workpiece holding units pivot to follow the radial direction of rotation of the rotation body and modify the long direction face of the single sheets when the rotation of the rotation body takes the workpiece holding units past the position where the cutter member is arranged. At this time, the workpiece holding units are arranged so that part of the workpiece holding units passes over a bed knife.

Delivery device

Equipment of manufacturing a wearing article includes a plurality of units movably arranged on a unit basis for transferring a half-completed product of the wearing article. The plurality of units is configured to perform the steps of shaping pulverized pulp into an absorbent body, sandwiching the absorbent body between first and second sheet members to obtain a continuous body of an absorbent main body, producing at least apart of a belt element, severing the continuous body to obtain the absorbent main body, affixing a pair of the belt elements to end sections of the absorbent main body, folding the absorbent main body in two, and superposing the belt elements on each other, joining the superposing belt elements at intervals at a to-be-joined portion to obtain the waist-belt section, and severing the continuous body corresponding to the to-be-joined portion for each waist-belt section to obtain the wearing article.
