FIXING DEVICE OF PLURALITY OF SHEETS ASSOCIATED WITH ABSORBENT ARTICLE, AND FIXING METHOD |
摘要 |
A fixing device for fixing an elastic sheet and a low-stretchable sheet via fixing parts while superposing the sheets in a thickness direction includes: a rotating member including protrusions on an outer peripheral surface to form the fixing parts and rotatable along a transport direction; and a sandwiching member arranged at a predetermined position of the rotating member in a rotational direction, and sandwiching the sheets by a surface portion in cooperation with each of the protrusions to form the fixing parts when each of the protrusions passes through the predetermined position, the surface portion being larger than a top surface of each of the protrusions. At a sandwiching position in which the sheets are sandwiched cooperatively by the sandwiching member and the rotating member, the low-stretchable sheet is located between the elastic sheet and the top surface of each of the protrusions of the rotating member. |

1. A fixing device of a plurality of sheets associated with an absorbent article, the fixing device fixing an elastic sheet that is transported along a transport direction and a low-stretchable sheet that has lower stretchability than that of the elastic sheet via a plurality of fixing parts while superposing the elastic sheet and the low-stretchable sheet in a thickness direction, the fixing device comprising:
a rotating member that includes a plurality of protrusions on an outer peripheral surface to form the plurality of fixing parts and rotates along the transport direction; and a sandwiching member that is arranged at a predetermined position of the rotating member in a rotational direction, and sandwiches the elastic sheet and the low-stretchable sheet by a surface portion in cooperation with each of the protrusions to form the fixing parts when each of the protrusions passes through the predetermined position, the surface portion being larger than a top surface of each of the protrusions, at a sandwiching position in which the elastic sheet and the low-stretchable sheet are sandwiched cooperatively by the sandwiching member and the rotating member, the low-stretchable sheet being located between the elastic sheet and the top surface of each of the protrusions of the rotating member the low-stretchable sheet being wrapped around the rotating member and being transported to the sandwiching position in a strained state between the protrusions. |
