20090098285 | Method And Apparatus For Forming A Batt Of Particulate Material For Use As A Component In An Absorbent Core Assembly - A method and apparatus for forming a wad of particulate material which may be used in an absorbent article. The apparatus may include a laydown drum having a plurality of vacuum zones, a plurality of fence zones, and a plurality of blow-off zones. The plurality of vacuum zones may be substantially permeable to permit vacuum air to pass through and into the laydown drum. The plurality of fence zones may be substantially impermeable to inhibit air to pass through. The plurality of blow-off zones may be substantially permeable to permit blown air to pass out of and through said laydown drum. The apparatus may also include a deposition chute for depositing particulate material on a web of material in close proximity to the laydown drum. A shield may also be attached to the deposition chute. | 04-16-2009 |
20100193110 | Method for High-Speed Continuous Application of a Strip Material to a Substrate Along an Application Path on the Substrate - Disclosed are examples of a method for applying a flexible longitudinal strip material, having longitudinal side edges and a width therebetween, along an application path on a substrate, comprising the steps of: continuously drawing the strip material longitudinally from a continuous supply; continuously urging the strip material into a concave shape across its width; and continuously bringing the strip material into contact with the substrate along the application path. | 08-05-2010 |
20100193135 | System and Method for High-Speed Continuous Application of a Strip Material to a Moving Sheet-Like Substrate Material at Laterally Shifting Locations - Disclosed are examples of a system for regulating the longitudinal strain in an elastic longitudinal material being applied to a sheet material in continuous fashion. The system may include a continuous supply of the sheet material; a continuous supply of the elastic longitudinal material; first and second feed rollers having a feed nip therebetween through which the elastic longitudinal material passes longitudinally, and downstream first and second joining rollers having a joining nip therebetween through which the sheet material and the elastic longitudinal material pass. The linear velocity of the circumferential surface of at least one of the first or second feed rollers is controlled relative to the linear velocity of the circumferential surface of at least one of the first or second joining rollers, to regulate longitudinal strain in the elastic longitudinal material. | 08-05-2010 |
20100193138 | System for High-Speed Continuous Application of a Strip Material to a Moving Sheet-Like Substrate Material at Laterally Shifting Locations - Disclosed are examples of a system for laterally shifting a longitudinally moving strip material as it enters a joining mechanism that urges the strip material into contact with a moving sheet material. The system may include a continuous supply of the strip material longitudinally moving in a downstream direction toward and into the joining mechanism, an electric motor having a drive shaft; and a strip guide arm connected to the drive shaft and situated upstream of the joining mechanism, the strip guide arm having a downstream strip retainer that slidably retains the strip material on the strip guide arm at a downstream location on the strip guide arm. | 08-05-2010 |
20100193139 | Strip Guide for High-Speed Continuous Application of a Strip Material to a Moving Sheet-Like Substrate Material at Laterally Shifting Locations - Disclosed are examples of a strip guide for laterally shifting a longitudinally moving strip material as it enters a joining mechanism that urges the strip material into contact with a moving sheet material, the strip guide comprising a surface over which the strip material passes longitudinally, the surface defining a U-shape. | 08-05-2010 |
20110042844 | METHOD AND APPARATUS FOR FORMING A BATT OF PARTICULATE MATERIAL FOR USE AS A COMPONENT IN AN ABSORBENT CORE ASSEMBLY - A method and apparatus for forming a batt of particulate material which may be used in an absorbent article.

20140377506 | Bonding Apparatus and Method - The present disclosure relates to methods and apparatuses for mechanically bonding substrates together. The apparatuses may include a pattern roll including a pattern element protruding radially outward. The pattern element includes a pattern surface and includes one or more channels adjacent the pattern surface. The pattern roll may be positioned adjacent an anvil roll to define a nip between the pattern surface and the anvil roll, wherein the pattern roll is biased toward the anvil roll to define a nip pressure between pattern surface and the anvil roll. As substrates advance between the pattern roll and anvil roll, the substrates are compressed between the anvil roll and the pattern surface to form a discrete bond region between the first and second substrates. As such, during the bonding process, some yielded substrate material flows from under the pattern surface and into the channel to form a channel grommet region. | 12-25-2014 |
20140377513 | Bonding Apparatus and Method - The present disclosure relates to methods and apparatuses for mechanically bonding substrates together. The apparatuses may include a pattern roll having three or more pattern elements protruding radially outward, wherein each pattern element includes a pattern surface. The pattern surfaces are also separated from each other by gaps having minimum widths. The pattern roll may be adjacent an anvil roll to define a nip between the pattern surfaces and the anvil roll, wherein the pattern roll is biased toward the anvil roll to define a nip pressure between pattern surfaces and the anvil roll. As substrates advance between the pattern roll and anvil roll, the substrates are compressed between the anvil roll and the pattern surfaces to form a discrete bond region between the substrates. During the bonding process, some of yielded substrate material also flows from under the pattern surfaces and into the gaps to form gap grommet regions. | 12-25-2014 |
