摘要:
Apparatus and methods are provided to allow for creation of a configured laminate of a non-woven material, to which a character strip is applied, the character strip exposed by either heat severing and removal of overlying materials, or intermittent application of overlying materials to leave the desired portions of the character strip exposed. A simultaneously formed core insert is applied to a preformed chassis web.

An apparatus for transferring articles such as absorbent cores or disposable diaper chassis components from a rotary mechanism, such as a pad turner, to a linear mechanism, such as a conveyor, for further processing. A puck on the apparatus is capable of stretching and rotating the article during this transfer procedure. The puck includes a pair of end segments each of which is arranged to move from a first position where each end segment is at a first distance and a first angle relative to the puck and a second position where each end segment is at a second distance and a second angle relative to the puck during the transfer process.

An apparatus and method is provided for single transfer insert placement. The apparatus receives continuous web material and cuts a discrete section or pad from the web. The pad is then supported on a single transfer surface. The single transfer surface then may spin the supported pad to a desired angle and provide the pad to a receiving surface at a desired interval.

An elastic ribbon is fed over a vacuum drum. Rotating cutter blades use the drum as an anvil to cut the ribbon into spaced apart segments. A sheet comprising a diaper web runs over a roll that is spaced from the drum. A segment transferring and stretching device is arranged between the drum and roll. One embodiment of the transferring device has grippers rotating together about the axes that are not coaxial but are at opposite acute angles relative to the roll and drum axes. The grippers engage an unstretched elastic segment on the drum when the grippers are close together but as they rotate they spread apart and stretch the segment which is then pressed onto the glue treated sheet. In another embodiment of the elastic segment stretching and transferring device, grippers are mounted to the periphery of a vacuum drum. At least one of the grippers is moved alternately toward and away from the other under the influence of a stationary cam as the drum rotates.

A pants type disposable undergarment is provided which is equipped with an elasticized side panel. The side panel is elasticized with elastic film. The elastic film is attached to a nonwoven layer. The elasticized nonwoven layer is then split into two sections. A portion of the elasticized nonwoven layer is then ultrasonically cut to the desired configuration. The elastic film does not traverse the crotch region. Also provided are methods for producing such disposable undergarments.

摘要:
A method for producing disposable undergarments is disclosed. The method generally comprises combining a first layer, comprising an elastic material sandwiched between layers of nonwoven material, and a second layer, comprising a backing material and a graphically printed applied patch of material layer.
摘要:
A method and apparatus for producing disposable undergarments having areas of defined elastic material is disclosed. The method provides for staggered cutting knives for severing the elastic material, which results in less necessary material used in the construction of the undergarments.
