Cutting device and manufacturing method for absorptive article

A method of manufacturing an absorptive article, said method comprising:

• folding a web having a continuous portion and a discontinuous portion, at a center of the web in a cross direction crossing a moving direction of the web;
• and
• cutting, by using a cutting device, the continuous portion of the web that is folded in two in the folding to obtain the absorptive article,
• wherein
• the absorptive article is a disposable diaper having waistband members,
• the continuous portion includes waistband regions corresponding to the waistband members,
• the discontinuous portion includes a crotch region located between one of the waistband regions and another one of the waist band region, and leg opening regions located on both sides of the crotch region,
• the waistband regions are stretchable in the moving direction,
• the crotch region is stretchable in the cross direction,
• in the folding, the web is folded at the crotch region to align an end of the one waistband region with an end of the another waistband region, and
• said cutting device further includes
• a die roll including a first large diameter portion whose outer peripheral surface is provided with a cutting blade to cut the continuous portion of the web;
• an anvil roll including a second large diameter portion disposed to face the first large diameter portion and defining with the first large diameter portion a region in which the first large diameter portion and the second large diameter portion contact and press each other in the cutting of the continuous portion of the web;
• a first conveyor that transports the continuous portion of the web downstream in the moving direction toward said region;
• and
• a second conveyor that transports the discontinuous portion of the web downstream in the moving direction, alongside said region, and without the discontinuous portion contacting the first large diameter portion and the second large diameter portion.
