Publication number: 20230404817Abstract: The present disclosure relates to apparatuses and methods for making tampons including primary and secondary absorbent members. During assembly, primary absorbent members, a continuous length of secondary absorbent members, and a continuous cord are advanced in a machine direction. Leading edges of the primary absorbent members are separated from each other in the machine direction by a pitch distance. Discrete secondary absorbent members are cut from the continuous length of secondary absorbent members. Leading edges of the discrete secondary absorbent members are also separated from each other in the machine direction by the pitch distance. The continuous cord is positioned on the secondary absorbent members. And a secondary absorbent member is positioned in contact with a primary absorbent member. A thread is combined with the continuous cord, the secondary absorbent member, and the primary absorbent member.Type: ApplicationFiled: September 1, 2023Publication date: December 21, 2023Inventors: Kevin Charles STRONG, Evan Joseph DURLING, Hinrich KNUTH, Khalid QURESHI

Publication number: 20230381030Abstract: A tampon comprising an absorbent pledget and a withdrawal cord attached to the pledget is disclosed. The withdrawal cord may be constituted predominantly (by weight) of natural plant fiber such as cotton, and comprise no more than 5 percent by weight material derived from petroleum, while exhibiting limiting wicking capability. A method for manufacturing tampons with withdrawal cords including cotton fiber is disclosed, including a scouring step in which the scouring solution is of relatively lower pH than is conventional for scouring cotton, is disclosed.Type: ApplicationFiled: May 24, 2022Publication date: November 30, 2023Inventor: Khalid QURESHI

Patent number: 9034230Abstract: A method for making an elastomeric apertured web comprises providing a precursor web comprising a laminate which is subjected to incremental stretching to form an elastomeric precursor web. A forming apparatus is provided comprising a first member and a second member, wherein the first member comprises a mating member, and the second member comprises teeth which are joined to the second member. The elastomeric precursor web is moved through the forming apparatus, wherein apertures are formed in the elastomeric precursor web material as the teeth on the second member penetrate the mating member forming an elastomeric apertured web. The elastomeric apertured web exhibits a WVTR of at least about 1000 g/m2/day.Type: GrantFiled: August 3, 2009Date of Patent: May 19, 2015Assignee: The Procter & Gamble CompanyInventors: Khalid Qureshi, Edward Lawrence Schmidt, Jr.
