2. Description of the Related Art Heretofore, sanitary napkins have been known as absorbent articles of this type, for example, a liquid-permeable top sheet on the front surface (contact surface with the skin) and a liquid-impermeable material on the back surface. In general, a sheet having an elastic back sheet and a liquid-absorbent core arranged between these sheets are used. In this sanitary napkin, the portion where the core is arranged in the top sheet is bulged due to the thickness of the core, so that when fitted on the napkin, it can be reliably fitted to the female genitalia. A large number of holes are formed in the top sheet for permeation of menstrual blood, and the menstrual blood that has permeated the top sheet is absorbed by the core.

This absorbent article such as a sanitary napkin includes, in addition to the napkin body composed of the above-mentioned top sheet, back sheet, core, etc., a release paper covering the adhesive portion on the back side of the napkin body, and a release sheet. It has an individual packaging sheet fixed to paper. That is, in a product state before use, the sanitary napkin is folded so that the individual packaging sheet is on the outside. Then, when using the napkin, the user or the like deploys the sanitary napkin and then applies a force to the individual packaging sheet in a direction of separating the individual packaging sheet from the napkin main body to separate the individual packaging sheet together with the release paper from the napkin main body. As a result, the napkin body is ready for use.

In the napkin body of this sanitary napkin, the core is arranged at a predetermined interval between the top sheet band and the back sheet band, and after joining these two sheet bands to form a bonded sheet band, It is manufactured by cutting the joining sheet strip between the cores. At this time, the napkin main bodies are in a state of being arranged at a predetermined interval so that the flow direction of the manufacturing line is the longitudinal direction.

Then, after the napkin body whose top sheet is in the horizontal state is conveyed in a substantially horizontal direction, the napkin body is attached to the vacuum drum of the napkin body with the top sheet side of the napkin body adsorbed by the vacuum drum of the napkin conveying device. Transport in the circumferential direction. Here, the vacuum drum is
It is formed in a substantially cylindrical shape and is configured to suck air inward from the peripheral surface side to adsorb the sanitary napkin to the peripheral surface side. That is, the napkin body is adsorbed on the lower side of the vacuum drum, and then conveyed to the side of the vacuum drum as the vacuum drum rotates.

When the front end in the flow direction of the napkin main body conveyed to the side of the vacuum drum is substantially upward, the back sheet is conveyed from the vacuum drum while adsorbing the back sheet side of the napkin main body. Transfer to the suction drum. The backsheet suction drum has a plurality of blocks arranged on the circumferential surface side by side in the circumferential direction, and the backsheet side of the napkin body is sucked by the blocks. Then, when the napkin body is conveyed by the back sheet suction drum, the block is rotated by about 90 °.
When rotated, the napkin main bodies are rearranged so that the width direction thereof becomes the flow direction, and adjacent blocks are brought closer to each other to close the space between the napkin main bodies. After this, the napkin body is transferred to the individual packaging vacuum, and the individual packaging film is continuously attached to the back side of each napkin body that is intermittently transported.
It is pasted into. And in this downstream process, after each napkin body is folded, the individual packaging film is cut,
Sanitary napkins are now being manufactured.
