摘要： A thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern provides visual and tactile cues as the films are stretched or elongated. The complex pattern can cause the thermoplastic film to have a complex stretch profile.

摘要： The methods herein relate to assembling an elastic laminate with a first elastic material and a second elastic material bonded between first and second substrates. During assembly, an elastic laminate may be formed by positioning the first and second substrates in contact with stretched central regions of the first and second elastic materials. The elastic laminates may include two or more bonding regions that may be defined by the various layers or components of the elastic laminate that are laminated or stacked relative to each other. In some configurations, a first plurality of ultrasonic bonds are applied to the elastic laminate to define a first bond density in the first bonding region, and a second plurality of ultrasonic bonds are applied to the elastic laminate to define a second bond density in the second bonding region, wherein the second bond density is not equal to the first bond density.

摘要： A multiple-ply thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern, when stretched or elongated and then released, can cause areas of billowing and delamination between plies of the multiple-ply thermoplastic film. The resulting billowed and delaminated areas form billow pockets for capturing liquids that can capture liquids when one of the plies is punctured.

摘要： The current invention concerns a method and apparatus for stretching and repitching an elastic member for attachment to a moving substrate, the elastic member being stretchable in at least a longitudinal direction and said elastic member in an essential non-stretched condition comprising an initial length along said longitudinal direction, the method comprising the steps of: (1) providing the elastic member in essentially non-stretched condition to a set of repitching members with an initial supply pitch, said set of repitching members comprising at least a first repitching member and a second repitching member, and optionally one or more repitching members arranged between said first and said second repitching member; (2) receiving said elastic members arranged in non-stretched condition between said set of repitching members, whereby the distance between the first and the second repitching member corresponds to the initial length of the elastic member; (3) moving at least said first and said second repitching members following trajectories diverging from each other, thereby stretching said elastic members arranged between the repitching members to an application length which is longer than the initial length and which corresponds to the length of said elastic member in elastically stretched condition, whereby said repitching members are moved with selectively variable velocity when transferring said elastic members to selectively vary the application pitch of said elastic member in stretched condition on said substrate, the variation of the speed of said repitching members determining the application pitch of said elastic member in stretched condition on said substrate, characterized in that during step (3), said set of elastic members are rotated around a common rotation axis while the elastic member is being stretched from the initial length to the application length. Additionally, the invention concerns a method and apparatus for stretching and repitching an elastic member for attachment to a moving substrate whereby the elastic members are held by repitching members, which are rotated at an essentially constant rotational speed around rotation axes in trajectories, said trajectories being defined by having a different radial distance from the rotation axis to the repitching member rotating around said rotation axis at the application position where the elastic member is attached to the substrate, than at the initial position where the elastic member is received by the repitching members, thereby changing the pitch of the elastic members.
