METHOD AND DEVICE FOR MANUFACTURING COMPOSITE SHEET RELATED TO ABSORBENT ARTICLE

PROBLEM TO BE SOLVED: To provide a method and a device for manufacturing a composite sheet related to an absorbent article by which a desired extension rate can be easily imparted to each part of a meandering pattern in accordance with it and variations in extension rate can be easily provided for the meandering pattern when a continuous body of elastic members in an extended state is joined to a continuous body of sheets to form the predetermined meandering pattern. SOLUTION: The method for manufacturing the composite sheet includes: a conveying process in which the continuous body of the sheets is continuously conveyed in the conveying direction; and a joining process in which the continuous body 121 of the elastic members is joined to the continuous body of the sheets while continuously changing the joining position of the continuous body 121 of the elastic members on the continuous body of the sheets in the perpendicular direction by feeding the continuous body 121 of the elastic members toward the continuous body of the sheets conveyed in the conveying direction through a guide member 60 which reciprocates in the cross direction perpendicular to the conveying direction. The guide member 60 has a rotary driven roller 63 which is rotary driven along the feed direction of the continuous body 121 of the elastic members while it is abutted on the continuous body 121 of the elastic members. The extension rate of the continuous body 121 of the elastic members is adjusted by changing the rotation speed of the rotary driven roller 63. COPYRIGHT: (C)2011,JPO&INPIT
