Abstract

The present invention provides a method of manufacturing disposable diapers. A process according to the present invention comprises feeding first and second webs and waist elastic members in a machine direction; joining the elastic members to the first and second webs and joining the webs to each other; joining to the first web; coating the first and second adhesive zones with adhesives; joining the second web folded inward in a cross direction to the first web and the panel in vicinities of transversely opposite side edges; successively cutting away transversely middle zones of the composite web along first cutting lines and folding the composite web together with the panel inward in the cross direction; and bonding respective halves of the composite web thus folded to each other in vicinities of second cutting lines and cutting the composite web together with the elastic members along the second cutting lines to make a plurality of the diapers.

Description

technical field [0001] The present invention relates to a method of making disposable diapers for absorbing and containing body exudates. Background technique [0002] A method of manufacturing disposable diapers has been proposed in which a continuous composite fabric is fed under tension in the machine direction, while a plurality of absorbent laminates, each extending in the transverse direction, are fed in the machine direction, etc. It is fed onto the inner surface of the composite fabric at intervals, and is continuously connected with the composite fabric (Japanese Patent Application Laid-Open No. 1999-107007A). [0003] More specifically, the method described in Japanese Patent Application Laid-Open No. 1999-107007A includes the steps of: cutting off a continuous composite fabric in the transverse direction along first cutting lines (each first cutting line substantially describes a circle) an intermediate region so as to form leg holes spaced a given distance apart...
