A method for manufacturing absorbent sanitary products, comprising the steps of: forming a first and a second continuous elastic band, which are movable parallel to each other in a machine direction, fixing a plurality of absorbent panels between said first and second continuous elastic bands, arranged in a direction transverse to the machine direction, and spaced apart in said machine direction, wherein each of said elastic bands is formed by means of a method comprising the steps of: continuously feeding a plurality of tensioned elastic threads (30) in said machine direction, continuously feeding a pair of non-elastic webs arranged on opposite sides of said plurality of elastic threads, welding said pair of non-elastic webs to each other by means of a welding pattern comprising anchoring welds and/or containing and guiding welds.

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 method for producing an elastic composite web for an absorbent sanitary article comprising a first corrugated web and a second web connected together, and at least one elastic element entrapped between said first web and said second web. The present invention also relates to an elastic composite web for an absorbent sanitary article.

A method of manufacturing a wearable article is disclosed. The method includes advancing a first layer of continuous sheet and a second layer of discrete continuous sheet having a smaller width than the first layer of continuous sheet; intermittently joining a first group of elastic bodies between the first layer of continuous sheet and the second layer of discrete continuous sheet; joining a second group of elastic bodies to the first layer of continuous sheets outward of the second layer of discrete continuous sheet; joining a center chassis with the first layer of continuous sheet and overlapping the first group of elastic bodies not joined to the first layer of continuous sheet; folding the first layer of continuous sheet to form a first layer fold over, wherein the first layer fold over overlaps the second group of elastic bodies, the center chassis, and the second layer of discrete continuous sheet.

Provided is a manufacturing apparatus for manufacturing a composite stretchable member capable of improving a function of preventing cutting by reducing a defect in which an elastic member is detached from a groove of a conveying roller. The manufacturing apparatus includes a guide device that guides the two sheets and the elastic members to a bonding device. The guide device includes a guide member that guides the elastic members to respective multiple grooves on an outer peripheral surface of a conveying roller of the bonding device. The guide member is provided at its leading end with multiple guide grooves for holding the corresponding elastic members. The guide member is disposed to allow the elastic members positioned between the guide grooves and the corresponding grooves of the conveying roller to each have a length of 30 mm or less.

Protective underwear including a chassis having an absorbent core, a backsheet, and a cover, and gathered elastic side panels attached to the chassis. The protective underwear is made by attaching the side panels along respective edge portions of the chassis while both the chassis and the elastic panels are moving in the machine direction.

The present disclosure relates to assembling elastic laminates that may be used to make absorbent article components. Methods herein may include an anvil adapted to rotate about an axis of rotation, wherein first and second spreader mechanisms adjacent the anvil roll are axially and angularly displaced from each other with respect to the axis of rotation. During the assembly process, a substrate may be advanced in a machine direction onto the rotating anvil. The first spreader mechanism stretches a first elastic material in the cross direction, and the second spreader mechanism stretches a second elastic material in the cross direction. The stretched first and second elastic materials advance from the spreader mechanisms and onto the substrate on the anvil roll. The combined and elastic materials may then be ultrasonically bonded together on the anvil to form at least one elastic laminate.

The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. First spools are rotated to unwind first elastic strands from a first unwinder in a machine direction. The first elastic strands are positioned between the first substrate and the second substrate to form an elastomeric laminate. Before the first elastic strands are completely unwound from the rotating first spools, second spools are rotated to unwind second elastic strands from a second unwinder. Subsequently, the advancement of the first elastic strands from the first unwinder is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first spools to a subsequently utilized elastic material drawn from the second spools.
