摘要： A method and apparatus for forming an article (94) includes a moving of a forming surface (22) through an operative forming chamber (24) along a forming path length (40). A first fibrous stratum (26) of fiber material (96) can be deposited onto the forming surface (22), and the first fibrous stratum (26) can have a first stratum thickness (28). A first quantity of a first superabsorbent material (30) can be directed to form a selected combination with the first fibrous material to provide a first superabsorbent-containing stratum. A second fibrous stratum (32) of fibrous material can be deposited to overlie the first fibrous stratum (26), and the second fibrous stratum (32) can have a second stratum thickness (34). A second superabsorbent material (36) can be directed to form a selected combination with the second fibrous material to provide a second superabsorbent-containing stratum.

摘要： This invention relates to an apparatus for transferring a discrete portion of a first web traveling at a first speed onto a second web traveling a second speed. The apparatus includes a converting mechanism capable of forming at least one discrete portion out of the first web. An anvil roll is positioned in close proximity to the converting mechanism and can travel at a rotational speed equal to the first speed. The anvil roll is a vacuum roll that is capable of directing the discrete portion away from the converting mechanism. A transfer roll is arranged in close proximity to the anvil roll and initially travels at a rotational speed equal to the first speed. The transfer roll forms a gap with the anvil roll through which the discrete portion can pass. The transfer roll is also a vacuum roll that is capable of directing the discrete portion away from the anvil roll. The transfer roll is capable of changing rotational speed to match the second speed during a single revolution. A backing roll is arranged in close proximity to the transfer roll and travels at a rotational speed equal to the second speed. The backing roll cooperates with the transfer roll to combine the discrete portion with the second web.

摘要： This invention relates to a method of transferring a discrete portion of a first web onto a second web. The method includes advancing the first web at a first speed and advancing the second web at a second speed. The first web is directed to a converting mechanism where a discrete portion is formed. The discrete portion is then transferred onto a vacuum anvil roll that is rotating at the speed of the first web. The method further includes transferring the discrete portion from the vacuum anvil onto a transfer roll that is also traveling at the first speed. The transfer roll is a vacuum roll that is driven by a servomotor and is capable of changing speeds quickly. The speed of the transfer roll is varied to match the speed of the second web and the discrete portion is transferred onto the second web.
