Abstract
The present disclosure relates to methods for manufacturing absorbent articles, and in particular, methods for making pre-fastened refastenable pant diapers. Aspects of the methods according to the present disclosure relate to the fabrication of refastenable pant diapers wherein discrete chassis are advanced in a machine direction such that the lateral axis is parallel with the machine direction. First side panels are then refastenably connected with the first waist region, and second side panels are permanently connected the second waist regions of the discrete chassis. The chassis are connected with discrete lengths of side panel material and/or connection zone material. The chassis are then folded, and the first and second side panels are subsequently bonded together. The article is then subjected to knife cut at or adjacent the bonded regions to create discrete, pre-fastened refastenable pant diapers.
