摘要： In absorbent products, such as sanitary napkins, discreet areas of dry fibrous materials such as fluid-repellent materials are precisely placed in various planes within the product so as to provide barriers to bodily fluid leakage from the product. In a preferred embodiment, hydrophobic fibers are placed around the periphery of a central absorbent area of an absorbent product to discourage and/or prevent side or end leakage from the product.

摘要： Apparatus and methods for forming improved airlaid fibrous articles are disclosed. Airlaying apparatus is provided which permits at least two types of fibrous materials to be defiberized and transported to a single airlaying apparatus. In a most preferred embodiment, a drum-type airlaying drum having a plurality of deposition cavities is provided. By controlling the airflow and pressure differential, selective placement of each type of fibrous material within a cavity is achieved. Also disclosed are improved deposition cavities which permit multiple materials to be airlaid and retained in position by providing a foraminous surface on at least a portion of the cavity sidewall. Most preferably, a hydrophobic fiber layer is formed and a layer of absorbent fiber is deposited within the first layer; the present invention permits a clear demarcation between the fiber types. Also disclosed is improved apparatus for removing airlaid articles from deposition cavities, using a precisely controlled airstream. Improved methods of making airlaid articles by regulating process parameters and using the improved apparatus of the present invention are also disclosed.

摘要： A method of forming an improved finger grip at the gripper end of a paperboard tampon tube is disclosed. This gripper end has an outwardly rolled edge produced by applying moisture to the gripper end of the paperboard tube having a diameter of less than about 25 mm, heating a forming tool to about 100.degree. F. to about 350.degree. F., rotating the paperboard tube with respect to the forming tool at a rate of about 50 to 1000 rpm, and contacting the gripper end of the paperboard tube with the forming tool for about 0.2 to about 5 seconds. In this manner, the forming tool rolls the gripper end of the paperboard tube outwardly to form a radiused surface at the outside of the gripper end of the paperboard applicator tube. The resulting tampon applicator is also disclosed.

摘要： An apparatus and method for making absorbent products in which a first material, such as absorbent fluff formed from wood pulp, is introduced into a vacuum forming chamber. A portion of the fluff is deposited into the cavity of a mold transported through the forming chamber by a forming wheel so as to form a layer of pure fluff within the bottom of the mold cavity. A second material, such as superabsorbent particles or heat stabilized fibers, is introduced into the forming chamber so that streams of the first and second materials collide within a mixing zone. As the mold continues it travel through the forming chamber, a mixture of first and second materials from the mixing zone is deposited within the mold cavity, thereby filling it. The portion of the mixture that extends above the surface of the mold is scraped off by a scarfing brush that directs the mixture back into the mixing zone, thereby creating turbulence that ensures thorough mixing of the two materials. The result is an absorbent product having a first layer formed by pure first material and a second layer formed by a mixture of the first and second materials.
