An individually wrapped absorbent article such as a sanitary napkin which is simple, compact, sanitary, and easy to unwrap for use and to dispose of after use. The absorbent article avoids the need for a separate peel strip and pouch because it is provided with a wrapper that can be folded into a pouch. Substantially the entire backsheet of the absorbent article directly faces the wrapper and is secured to it to form an assembly. In the case of a winged or tabbed type absorbent article, this configuration obviates the need for a separate peel strip to cover the garment adhesive located on the wings or tabs. The assembly is wrapped by folding the lateral flaps thereof longitudinally over one another to enclose the article to prevent the garment adhesive from becoming contaminated. The package is then tri-folded laterally to form an e-shaped pouch. Wrapping and folding are performed by an in-line process that uses simple equipment and that does not require reversal in the direction of article conveyance. Folding is performed by a tri-folding mechanism that translates to convey wrapped packages through an in-line tri-folder assembly and that rotates to fold the packages into the e-shaped pouches.

When a sheet bundle is being conveyed by any one pair of plural pairs of rollers independently movable toward and away from the bundle sheet, before the bound portion of the sheet bundle passes the pair of rollers, the pair of rollers on the downstream side nearest to the bound portion are separated from the sheet bundle, and the pairs of rollers more downstream than that pair convey the sheet bundle. Thereby, it happens less often that the pairs of rollers gather the air collected between adjacent ones of the sheets of the sheet bundle to the bound portion to thereby cause a slack to the sheets, and the occurrence of wrinkles or twists in the sheet bundle can be reduced. Also, the pair of rollers are separated from the sheet bundle before the bound portion passes the pair of rollers, whereby it happens less often that the pair of rollers are damaged by the bound portion, and the sheet bundle can be conveyed smoothly.

A sheet folding device includes a folding plate configured to push out a sheet or sheet stack in a direction pre-set against a conveying path; a couple of folding rollers configured to push the sheet being pushed into a nip of the folding roller couple; and a guide part configured to guide the sheet or the sheet stack so as to prevent the sheet from coming contact in with the folding rollers in the conveying path where the sheet or the sheet stack is conveyed. The sheet or the sheet stack is folded while being put between and conveyed by the couple of the folding rollers.

The sheet processing apparatus is equipped with a process tray on which sheets conveyed are stacked, a return belt which moves the sheets stacked on the process tray, a trailing edge stopper which receives an end portion of the sheets moved by the return belt, and a conveyance assist roller which comes into contact with the sheets on the upstream side of the return belt with respect to the sheet moving direction and imparts a load to the movement of the sheets. The return belt moves the sheets to which a load has been imparted by the conveyance assist roller and causes them to be abutted on the trailing edge stopper.

Aspects of the present disclosure relate to tucking opposing side panels into a chassis of a diaper pant. The apparatuses and methods may utilize one or more conveyors that advance the chassis along a machine direction. Each conveyor may have a vacuum zone that applies a vacuum force to hold the chassis. The chassis may be positioned between a first conveyor having a first vacuum zone and a second conveyor having a second vacuum zone. The conveyors may apply opposing vacuum forces to hold the first waist region apart from the second waist region while the chassis advances in the machine direction toward a tucking device. The vacuum forces are then removed from the waist regions as the tucking device pushes the side panels toward each other. Pushing the side panels toward each other causes the inner surfaces of the waist regions to simultaneously move toward each other.
