Abstract

The present disclosure relates to methods for sealing absorbent cores of disposable diaper pants during the assembly process. The diaper pants may include a chassis connected with a ring-like elastic belt. Aspects of the assembly methods involve bonding a continuous length of absorbent cores between a continuous topsheet substrate and a continuous backsheet substrate advancing in a machine direction. The combined continuous topsheet substrate, continuous backsheet substrate, and continuous length of absorbent cores are then cut along a cross direction to create discrete chassis, wherein the topsheet, the backsheet, and the absorbent core of each chassis have equal longitudinal lengths. The discrete chassis are then deposited onto a first continuous elastic laminate and a second continuous elastic laminate. Opposing end regions of the absorbent cores may then be sealed by positioning a sealing layer across the topsheets of the chassis.
