Abstract: Pulpless absorbent cores and methods of manufacture are disclosed. A first exemplary absorbent core may comprise a carrier sheet having a first edge region, a central region, and a second edge region and particulate material disposed on the carrier sheet through the first edge region, the central region, and the second edge region. The absorbent core may additionally have an absorbent core width and the central region may have a central region width, and the central width may comprise between 33% and 75% of the absorbent core width. Further, the central region may comprise an average basis weight of particulate material that is at least 110% of an average basis weight of particulate material within at least one of the left edge region and the right edge region.

Abstract: Pulpless absorbent cores and methods of manufacture are disclosed. A first method for forming an absorbent core may comprise advancing a carrier sheet on a foraminous forming surface in a machine direction, the foraminous forming surface having a width extending in a cross-machine direction, creating a pressure differential across the forming surface, applying a first adhesive onto the carrier sheet, advancing the carrier sheet within a particulate material delivery chamber, and dispensing particulate material from a particulate material inlet within the particulate material delivery chamber to deposit the particulate material onto the first adhesive, wherein the particulate material inlet has a width that is between 25% and 75% of the foraminous forming surface width, and wherein the particulate material is delivered from the particulate material inlet at less than 900 meters per minute.
