In a process for making disposable diapers, a first web is continuously fed in its longitudinal direction. Tape fastener members extending in the longitudinal direction are fed to the first web so as to straddle respective lines corresponding to the side edges of the respective backsheets. Each of the tape fastener members has its longitudinally opposite end portions folded in a Z-shape or an inverted Z-shape. Top sections of these Z-shape and inverted Z-shape are coated on their undersides with a first self adhesive and bottom sections of these Z-shape and inverted Z-shape are coated on their undersides with a second self-adhesive. The tape fastener member is bonded to the first web by means of the second self-adhesive. The first web and the tape fastener members are simultaneously cut along the lines.

Process for making a disposable diaper

An article turning-round apparatus includes a rotary table rotated by a first shaft, load-carrying tables mounted on the rotary table along a peripheral zone thereof, a first conveyor serving to convey articles to a first station and a second conveyor serving to convey the articles away from a second station. Each load-carrying table is either a first load-carrying table adapted to rotate counterclockwise or a second load-carrying table adapted to rotate clockwise around its own axis as it moves along with the peripheral zone of the rotary table. The articles are successively loaded, at the first station, on these load-carrying tables. The first load-carrying table is turned counterclockwise approximately by 90&#xb0; and the second load-carrying table is turned clockwise approximately by 90&#xb0; in the course of traveling from the first station to the second station.

Article turning-round apparatus

The present invention aims to provide an article turning-round apparatus improved so that a series of articles can be successively turned round at a high velocity and there is no restriction imposed on the positions at which the articles are loaded and unloaded. An article turning-round apparatus comprises a rotary table adapted to be rotated by means of a first shaft, a plurality of load-carrying tables mounted on the rotary table along a peripheral zone thereof, a first conveyor belt assembly serving to convey diapers to a first station and a second conveyor belt assembly serving to convey the diapers away from a second station, wherein each of the load-carrying tables consists of a first load-carrying table adapted to move along the peripheral zone of the rotary table and a second load-carrying table adapted to rotate around its own axis in the peripheral zone of the rotary table while these second load-carrying tables move along the peripheral zone of the rotary table and wherein the articles are loaded, in the first station, on these load-carrying tables and the second load-carrying tables are adapted to rotate around their own axes approximately by an angle of 180&#xb0; in the peripheral zone of the rotary table while these second load-carrying tables move from the first station to the second station.
