Patent number: 6689416Abstract: A system and a method for providing feedback control of the deposition of superabsorbent particles into an absorbent core at a specified rate are disclosed herein. A control system, such as a programmable logic control device, is used to receive feedback related to the operation of one or more elements of a vibratory feeder. Based on the feedback, the control system adjusts one or more elements of the vibratory feeder to synchronize the operation of the elements of the vibratory feeder. Particularly, the control system can be adapted to synchronize the deposition rate of superabsorbent particles into the absorbent core with the line speed of the absorbent core during ramp-up and ramp-down periods.Type: GrantFiled: January 25, 2002Date of Patent: February 10, 2004Assignee: Paragon Trade Brands, Inc.Inventors: Troy Delzer, John Walter

Patent number: 6646180Abstract: A disposable absorbent garment having a topsheet, a backsheet and an absorbent core located between the topsheet and backsheet. The absorbent core is formed from a folded laminate having an upper layer, a lower layer and a central fibrous layer that are bonded together and together assist to maintain the dry and wet integrity of the core. The fibrous layer includes about 50 to 95 percent by weight superabsorbent polymer and about 5 to 50 percent by weight stabilization additives. The upper and lower layers may be tissue, airlaid fluff pulp or synthetic non-woven fibrous layers. Folding the thin absorbent laminate provides an absorbent core that can handle large doses of urine, by providing a central channel having a free volume for temporary liquid storage and increasing the surface area of the laminate available for liquid absorption. The garment thus formed is thin, lightweight and economical.Type: GrantFiled: October 2, 2000Date of Patent: November 11, 2003Assignee: Paragon Trade Brands, Inc.Inventor: Harry Chmielewski
