Abstract: An absorbing article, in particular an absorbing structure has at least one layer that can be used with advantage as a surface layer or in combination with a surface layer. The aforementioned layer has deformable fibers which are deformed and shrink when they become wet. The aforementioned layer thus constitutes a deformation layer and has at least one distinct admission passage. The admission passage is deformed and dilated when it becomes wet. In addition to improved admission in conjunction with repeated wetting, the article also offers a solution to the problem of feces handling in combination with repeated wetting.

Abstract: A pant-type absorbent article having a first body panel and a second body panel, the first and second body panels being interconnected by side panels. The respective side panel is formed by a bridge member having a first longitudinal edge portion attached to the first body panel and a second longitudinal edge portion attached to the second body panel, the bridge before use of the article being folded in an accordion-like fashion and can be extended and unfolded when the article is to be used so as to form the side panels of the article. In one embodiment at least one of the bridge members is refastenably attached to one body panel, wherein a first fastening member is arranged on the bridge member at or close to one longitudinal edge portion thereof and a complementary second fastening member is arranged on the respective body panel.

Abstract: A method for producing diaper component parts (3) from strip material (5, 8), wherein the strip material (5, 8) is fed continuously, by means of conveying means (6), along a straight path (P) extending through a number of work stations (9, 16, 21) synchronized with one another; and wherein, along the path (P), the strip material (5, 8) is secured to the conveying means (6) so that all points of the strip material (5, 8) travel at the same speed.

Abstract: The present invention relates to a distributor for particulate material comprising a cylinder and a feeder screw mounted therein for conveying particulate material in the cylinder from an inlet to an outlet.

Abstract: An arrangement for depositing particles onto a moving material web includes a particle dispenser and a perforated belt which moves over the material web. According to the invention, the particle dispenser is intended to dispense particles continuously in a uniform and wide flow whose width is equal to or somewhat greater than the width of the hole-pattern of the belt and the belt is spaced at a distance from the material web which is at least sufficiently large for the particles deposited on the material web to be accommodated between the belt and the web. The arrangement also includes means which function to remove particles caught by the belt without the particles falling down onto the underlying material web. These means are located downstream of the particle dispenser. The invention also relates to a method for depositing particles to a moving material web.
