Accordingly, almost no tension is loaded on the portion of the continuous fibrous sheet 10 slanted obliquely between the respective tooth tips 25b and 26b of gear teeth 25 and 26 that neighbor on each other and engage with each other. At this time, the continuous fibrous sheet 10 is brought in pressure contact with the respective tooth tips 25b and 26b of gear teeth 25 and 26, whereby the continuous fibrous sheet 10 is bent and folded sequentially in the machine direction MD, and then continuous undulating gathers 29 in the machine direction MD are formed.

Accordingly, non-elastomeric fibers constituting the continuous fibrous sheet 10 should not be stretched to be mechanically fractured at the time of formation of the gathers 29, and holes are made on a part of the continuous fibrous sheet 10. Further, as compared with the case of inclusion of elastomeric fibers, the continuous fibrous sheet 10 easily forms a habit to keep folding lines in gathers. Accordingly, gathers should not return to the flat shape and the bulkiness deceases.

Accordingly, even if fibers swell by being impregnated with water or medical solution, the configuration of the gathers 29 should not collapse greatly. As a result, the continuous fibrous sheet 10 is provided with required bulkiness and flexibility. Therefore, when the continuous fibrous sheet 10 is used as a sheet for wiping a bottom of a newborn baby, soft feces peculiar to a newborn baby is sufficiently wiped (scraped) by utilization of the undulating shape of the gathers.

As a result, the continuous fibrous sheet 10 is more easily molded into a predetermined configuration.
