The present disclosure relates to apparatuses and methods for making patterned apertured substrates that may be used as components of absorbent articles. During the manufacturing processes, a precursor substrate advances in a machine direction between a pattern roll and an anvil roll. The pattern roll rotates about an axis of rotation and includes a plurality of pattern surfaces, wherein the substrate is compressed between the anvil roll and the pattern surfaces of the pattern roll to form discrete bond regions in the substrate. The pattern surfaces on the pattern roll are formed on continuous threads extending circumferentially around the axis of rotation along helical paths parallel with each other. As such, the pattern surfaces press the substrate against the outer circumferential surface of the anvil roll in the different axial locations along the cross direction as the pattern roll rotates when forming the discrete bond regions.

A packaging plant of groups of absorbent sanitary articles able to create various types of customized packages in relation to the needs of consumers, automatically and without interruptions in the production of absorbent sanitary articles. The present invention also relates to a method for managing a packaging plant. The present invention also relates to a transport apparatus for absorbent sanitary articles, as well as to a method for transporting absorbent sanitary articles.

Disposable absorbent articles are disclosed herein along with method of making the same. The disposable absorbent article has a topsheet, a backsheet, and an absorbent system between the topsheet and the backsheet. The absorbent system has a first absorbent core and a second absorbent core which are offset from one another. An adhesive layer is disposed between the first absorbent core and the second absorbent core, at least in part.

A method and apparatus for producing absorbent sanitary articles including an absorbent body having two front oblique sides and two rear oblique sides, and two longitudinal elastic bands attached to the absorbent body along said oblique sides, where each of said elastic bands includes a front section and a rear section separated from each other by transverse cuts and joined together by refastenable closure formations.

A method and apparatus for producing elastic laminates, wherein a first continuous elastic film is stretched in a transverse direction by a spreader device and is applied on a transfer wheel on which it is cut longitudinally to form at least two parallel continuous elastic films which are transferred on a non-woven web held on an outer cylindrical surface of an anvil wheel.

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. A first beam is rotated to unwind a first plurality of elastic strands from the first beam in the machine direction. The first plurality of elastic strands are positioned between the first substrate and the second substrate to form the elastomeric laminate. Before the first plurality of elastic strands are completely unwound from the first beam, a second beam is rotated to unwind the second plurality of elastic strands from the second beam. Subsequently, the advancement of the first plurality of elastic strands from the first beam is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first beam to a subsequently utilized elastic material drawn from the second beam.

The present disclosure relates to methods and apparatuses for assembling elastic laminates that may be used to make absorbent article components. Particular aspects of the present disclosure include 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 elastic material; elongating the activated elastic material using a spreader mechanism; 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 using an anvil and an ultrasonic device.

A method and to a device for handling hygiene products, in particular nappies, wherein the products are transported by a feed conveyor in a first transport direction into compartments of a removal conveyor, in particular a grouping conveyor, which transports the products in a second transport direction, wherein the second transport direction extends transversely, in particular perpendicularly, to the first transport direction. At least one intermediate conveyor which serves to reduce the transport speed of the products in the first transport direction is located between the feed conveyor and the removal conveyor.

Pulpless absorbent cores and methods of manufacture are disclosed. A method of forming a pulpless absorbent core may comprise moving a foraminous forming surface having un-masked portions and masked portions in a machine direction, the un-masked portions defining an absorbent core region. The method may further comprise depositing particulate material at a velocity of less than 1200 meters per minute in the absorbent core region while applying a vacuum. The absorbent core region may comprise: a front core region spanning a first half of the absorbent core region and a rear core region spanning a second half, wherein the front core region trails the rear core region in the machine direction, and the masked portions of the foraminous forming surface block airflow through the forming surface to cause greater than 60% of the particulate material deposited in the absorbent core region to locate in the front core region.

An apparatus and method for applying a first web to a base web in a nonlinear pattern as the base web is advanced in a machine direction in contact with a back-up roller are disclosed. The apparatus can include a guide roller and a guide roller translations system. The guide roller can be configured to define a nip with the back-up roller. The guide roller translation system can be configured to allow the guide roller to move with respect to the back-up roller to control the position of the nip to allow the first web to be applied to the base web in the non-linear pattern in the machine direction.
