  • Patent number: 9314380
    Abstract: 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.

  • Patent number: 9145267
    Abstract: 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.

  • Patent number: 8403018
    Abstract: 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.

  • Publication number: 20130059714
    Abstract: A folding unit extends in the MD2 direction and has a central guide that comes into contact with the bottom of the crotch part, a pair of side guides that come into contact with the front waist and the rear waist, and a layering roller that lays the front waist and the rear waist one on the other. The space between the pair of side guides becomes narrower in the downstream conveyance direction. The ends of the side guides are located further upstream in the conveyance direction than the end of the central guide. The layering roller lays the front waist and the back waist one on the other further downstream in the conveyance direction than the side guides.

  • Publication number: 20110114264
    Abstract: It is possible to reduce a construction time for a manufacturing equipment of a wearing article. A manufacturing equipment of a wearing article including an absorbent main body and a waist-belt section, the absorbent main body having an absorbent body 1 that absorbs fluid and being applied to a crotch, the waist-belt section covering a waist around. The manufacturing equipment includes a plurality of units that are movably arranged on a unit basis, between which a half-completed product of the wearing article is transferred along a certain first direction, that respectively have a planar size in which a length in a second direction perpendicular to the first direction is longer than in the first direction, whose respective height and lengths of the first direction and the second direction are within a size range so that the units can be respectively accommodated in a container according to the JIS or ISO standard.
