Abstract: The present invention is an equipment and a process for the handling of fibrous webs that comprise particulate additives, which are positioned within interstices between the fibers and/or on the surface of the webs. By applying the present invention, predetermined regions are created in the web, which are essentially free of the particulate additives.

Abstract: The present invention relates to the field of hygiene appliances, in particular to hygiene articles comprising a means for reducing soiling of the skin of a wearer by body exudates such as faeces, urine, or menses. In particular, it relates to an article with a Skin Protection Sheet (SPS) that comprises a rear opening in registry with the anus during use, and a front opening in registry with a body exudate releasing body opening or genital organ. The openings are urged to the body by a pull means, whilst being spread open cross-directionally, allowing exudates to pass through. Such a hygiene article may suitably be a baby or adult diaper or pant, a training pant, or a menstrual pant.

Abstract: The present invention is a roll as may function as an anvil roll that comprises protrusions on its outer surface, that are outwardly or z-directionally oriented arcs of an arc wire such as wavy wire or an axially canted helical coil extending along a length or x-direction, which are pinched perpendicularly to the z- and x-direction. Such anvil rolls may be used to treat materials such as web materials, such as by embossing or bonding these web materials. In a particular application, such rolls may interact with an ultrasonic sonotrode.

Abstract: The present invention is a method for selectively machine directionally stretching a predetermined section of a pre-combined web material of varying material width by running the web over stretching rolls operated at a speed differential

Abstract: The present invention is an equipment and a method for handling web materials, in particular for recombining portions as are cut out from an essentially continuous web material machine-directionally offset with this web.

Abstract: The present invention relates to an apparatus for thermally treating webs which comprise thermoplastic respectively meltable compounds, thereby creating cylindrical or elliptic consolidation regions which may optionally comprise an aperture by employing a thermal energy source, such as ultrasonic energy, as well as to webs comprising elliptic consolidation regions. In a particular aspect the invention concerns apparatus and methods for creating the consolidation regions by using an anvil with a contact member that is supported by support ribs in its outer or proximal portion.

Abstract: The present invention is an absorbent article and a method for the manufacture of such an article without the need for including adhesives or glues for a construction connection, but rather including melt-fusion bonds respectively bonding, preferably by employing ultra-sonic connecting, more preferably ultra-sonic connecting using a flexible anvil. The present invention is also applicable to open type diapers, diapers with overfolded side margins and pre-closed pant-style diapers.

Abstract: The present invention relates to a novel equipment and a manufacturing process for separating a series of web pieces from an essentially continuous web and essentially concurrently forming an overfold along a cross-directionally extending fold line. The separating and overfolding may very advantageously be applied in the manufacturing of articles to be worn on the lower torso of a wearer, such as disposable absorbent articles, or disposable underwear.

Abstract: An apparatus and methods for thermally treating webs having thermoplastic respectively meltable compounds, thereby creating cylindrical or elliptic consolidation regions which may optionally have an aperture by employing a thermal energy source, such as ultrasonic energy, as well as to webs with elliptic consolidation regions. In a particular, the apparatus and methods create consolidation regions by using an anvil with a flexible elongated member, such as a wire, a chain or a tubular anvil with circumferential ribs.

Abstract: Apparatus and process for the manufacture of articles to be worn on the lower torso of a wearer, such as disposable absorbent article like diapers, training pants, adult incontinence articles, feminine care articles and the like. In particular to such articles and to the equipment and the process for manufacturing such articles, especially when different sizes or types of the article are to be prepared on the same equipment.

Abstract: The present invention is an article such as an article to be worn on the lower torso of a wearer, such as pants or diapers. The article has a flexible faeces separation member, such as a faeces trap sheet, which is attached in a particular way such that an effective separation of faeces from skin respectively genitals can be achieved.

Abstract: The present invention is an absorbent structure comprising a fibrous matrix (110), meltfusionable material and superabsorbent polymer particles (140). The absorbent structure is bonded by a meltfusion bond point (200) pattern, which is preferably created by ultrasonic welding.

Abstract: An article to be worn on the lower torso of a wearer, such as pants or diapers. The article exhibits snug fit on a wearer through a particular cooperative arrangement of the side panels and the centre strip. It may further exhibit a particular bulging such as in the hip region of the wearer, and/or may include hoops such as for encircling the legs of a wearer. The article relates further to a simple manufacturing process for such articles. In a particular variant of the process, “multilane” manufacturing may be employed also to larger size article. In another particular variant, side margins of parts of the article can be connected without connecting these to further underlying parts.

Abstract: An article such as an article to be worn on the lower torso of a wearer, such as pants or diapers. The article has a flexible faeces separation member, such as a faeces trap sheet, which is attached in a particular way such that an effective separation of faeces and skin respective genitals can be achieved.
