Abstract

Official abstract text for this publication.

Aspects of the present disclosure relate to methods for making tampons including primary absorbent members and secondary absorbent members. In some configurations, the tampons may be constructed with a primary absorbent member formed by a primary absorbent pad in a rolled configuration. In some configurations, the tampons may be constructed with a primary absorbent member formed by first and second primary absorbent pads positioned in a crossing configuration.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for making a tampon, the method comprising steps of: providing a primary absorbent pad comprising a first side edge and a second side edge separated from the first side edge to define a width, the primary absorbent pad further comprising a first end edge and a second end edge separated from the first end edge to define a length; positioning a flexible member on the primary absorbent pad, wherein a first portion of the flexible member extends outward from the first side edge of the primary absorbent pad and wherein a second portion of the flexible member extends from the first side edge toward the second side edge of the primary absorbent pad, wherein the flexible member is positioned adjacent the first end edge or the second end edge of the primary absorbent pad prior to rolling; and rolling the primary absorbent pad into a generally cylindrically shaped primary absorbent member comprising a withdrawal end region and an opposing insertion end region, wherein the first portion of the flexible member extends outward from the withdrawal end region of the primary absorbent member and wherein the second portion of the flexible member is enveloped by the primary absorbent member. 2. The method of claim 1 , wherein the flexible member comprises a secondary absorbent member. 3. The method of claim 1 , further comprising a step of connecting a withdrawal cord with the primary absorbent pad. 4. The method of claim 3 , wherein the step of connecting the withdrawal cord further comprises looping the withdrawal cord around the first side edge and the second side edge of the primary absorbent pad before the step of rolling the primary absorbent pad. 5. The method of claim 4 , wherein the step of connecting the withdrawal cord further comprises inserting the withdrawal cord through the primary absorbent pad and the second portion of the flexible member. 6. The method of claim 5 , wherein the step of connecting the withdrawal cord is performed after the step of rolling the primary absorbent pad. 7. The method of claim 1 , wherein the step of rolling further comprises rolling the primary absorbent pad from the first end edge toward the second end edge such that the first end edge is positioned radially inward from the second end edge in the generally cylindrically shaped primary absorbent member. 8. A method for making a tampon, the method comprising steps of: providing a primary absorbent pad comprising a first side edge and a second side edge separated from the first side edge to define a width, the primary absorbent pad further comprising a first end edge and a second end edge separated from the first end edge to define a length and a first end region and a second end region separated by a central region; positioning a flexible member on the primary absorbent pad, wherein a first portion of the flexible member extends outward from the first side edge of the primary absorbent pad and wherein a second portion of the flexible member extends from the first side edge toward the second side edge of the primary absorbent pad, wherein the flexible member is positioned in the first end region or the second end region of the primary absorbent pad prior to rolling; and rolling the primary absorbent pad into a generally cylindrically shaped primary absorbent member comprising a withdrawal end region and an opposing insertion end region, wherein the first portion of the flexible member extends outward from the withdrawal end region of the primary absorbent member and wherein the second portion of the flexible member is enveloped by the primary absorbent member.
