Methods for sealing absorbent cores on absorbent articles

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.
