A method for manufacturing an absorbent article, said method comprising guiding a first sheet material along a rotating member, wherein a surface of said rotating member is provided with a pattern with at least one suction zone and at least one non-suction zone; applying an absorbent material on said first sheet material on the rotating member; locally removing the absorbent material applied on at least one attachment portion of the first sheet material located above the at least one non-suction zone, such that at least one remaining portion of the first sheet material located above the at least one suction zone is covered with absorbent material and substantially no absorbent material is present on the at least one attachment portion; applying a second sheet material on top of the absorbent material on the first sheet material.

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.

A process for packaging a product arranged on a support comprising unrolling a film, moving the film to a packaging assembly defining at its inside a packaging chamber, progressively moving a number of supports inside the packaging chamber of the packaging assembly, closing the packaging chamber with the film sheets held above the respective support, optionally causing one or both of: a gas withdrawal from the hermetically closed packaging chamber and gas injection of a gas mixture of controlled composition, heat sealing the film to said support, wherein the heat sealing uses one or more heaters having heating surfaces which are heated for discrete and short time periods only. An apparatus for performing the above process is also disclosed.

The present disclosure relates to methods for assembling elastic laminates that may be used to make absorbent article components. Particular aspects of the present disclosure involve providing a first substrate and a second substrate, the first substrate and the second substrate, each having a width in a cross direction; providing an activated elastic material; elongating the activated elastic material; and ultrasonically bonding the first substrate together with the second substrate with the elongated activated elastic material positioned between the first substrate and the second substrate.

A method of manufacturing a can lid composed of a composite material comprising at least one sheet metal part, in particular an aluminum part or a tin plate part, and at least one plastic part, in particular composed of polypropylene or polyethylene terephthalate, wherein the plastic material and the sheet metal part are joined together by pressing together and by inductive heating to effect a stable connection with an effort and a manufacturing time that are as small as possible.

An apparatus for joining, in particular laser welding, two components, in particular plastics components, comprisestwo workpiece receptacles (1, 3) for respectively holding the two components (2, 4) to be connected, in each case one bearing element, preferably a bearing plate (7), for each of the workpiece receptacles (1, 3), a clamping drive (SA) for at least one bearing element for feeding and bracing of the two components (2, 4) held in the workpiece receptacles (1, 3) during the joining process, a controller (9) for the clamping drive (SA) and in particular a laser welding device (LS), anda mechanically loose coupling between the clamping drive (SA) and bearing element (7) such that the two workpiece receptacles (1, 3) are tiltable towards one another during feeding and bracing. Also disclosed is a method for operating such a joining apparatus during a joining process of two components (2, 4) held in the workpiece receptacles (1, 3), in particular during a laser welding process.

A method forms a butt joint between ends of first and second plies and splices the first and second plies together. The method includes the steps of: positioning a first splice edge of a first ply at a first location; positioning a second splice edge of a second ply at a second location, the second splice edge being left bare; wrapping a gum strip around the first splice edge such that the first gum strip forms a U-shaped structure in section that allows the first gum strip to extend from a first planar side of the first ply over the first splice edge to a second opposite planar side of the first ply; not wrapping a gum strip around the second splice edge; placing the first splice edge in abutting relationship to the second splice edge; and stitching the first splice edge to the second splice edge such that stitches each extend from the first planar side of the first ply, through the gum strip, to the first planar side of the second ply.

The present disclosure relates to methods for assembling elastic laminates that may be used to make absorbent article components. Particular aspects of the present disclosure involve a spreader mechanism operating to activate an elastic material by stretching the elastic material in to a first elongation. The elastic material is then consolidated to a second elongation, wherein the second the elongation is less than the first elongation. The consolidated elastic material is then joined to one or more substrates. In some configurations, the substrates may be nonwovens, and the elastic material may be an elastic film and/or an elastic laminate.
