Manufacturing method and manufacturing apparatus for a composite sheet associated with an absorbent article

A manufacturing apparatus for a composite sheet associated with an absorbent article, in which a continuous body of an elastic member is in a stretched state and is bonded with a continuous body of a sheet, comprising:

• a conveying mechanism that conveys continuously the continuous body of the sheet in a conveying direction;
• and
• a guiding member
• that transports the continuous body of the elastic member towards the continuous body of the sheet while moving back and forth the continuous body of the elastic member in an intersecting direction that intersects the conveying direction, the continuous body of the sheet being traveling in the conveying direction, and
• that bonds the continuous body of the elastic member with the continuous body of the sheet while a position on the continuous body of the sheet at which the continuous body of the elastic member bonds with the continuous body of the sheet is continuously changing in the intersecting direction by the transporting, wherein
• the guiding member includes a drive roller that, while being contact with the continuous body of the elastic member, is driven and rotated along a transporting direction of the continuous body of the elastic member, and
• by changing a rotation speed of the drive roller, a stretching ratio of the continuous body of the elastic member is adjusted.

A manufacturing apparatus for a composite sheet associated with an absorbent article according to claim 4, wherein

• the second drive mechanism includes
• a drive shaft that is driven and rotated,
• a second relay pulley that is disposed so as to rotate about a same axis as the relay pulley in an integrated manner with the relay pulley, and
• a second endless belt that is wrapped around the drive shaft and the second relay pulley, and
• in a path of the second endless belt, a section from the drive shaft to the second relay pulley is parallel to a rotation centerline of the axis.
