Abstract: A material laminate (1) with a planar dimension and a thickness direction perpendicular to the planar dimension, comprises a first liquid-permeable fibrous material layer (2) and a second liquid-permeable, porous and resilient material layer (3), with at least one of the material layers (2, 3) including thermoplastic material and the two material layers (2, 3) being mutually connected by the material laminate (1) exhibiting bonding sites (4) within which the thermoplastic material has been caused to at least partially soften or melt and thereby bond together the two material layers (2, 3). The bonding areas are arranged in two or more groups (5) with at least two bonding sites (4) in each group (5), with the greatest relative distance between two bonding sites (4), which are situated adjacent to each other, in a particular group (5) being less than the shortest distance between the group (5) and its closest adjacent group (5), as a result of which the material laminate (1) exhibits bond-free areas (6) between the bonding sites (4) within each bonding group (5) which have a higher density than bond-free areas (9) of the material laminate which are situated between the bonding groups (5). The laminate may be used as an outer layer on absorbent products such as nappies, panty nappies, incontinence shields, sanitary towels or bandages.

Abstract: The invention relates to a device and a method for producing a material laminate (1) by fixing pieces of material (2) at a given distance from one another on a first continuously advanced material web (4). The invention is characterized in that the pieces of material (2) are cut from a second continuous web (7) in a first station (3) and are conveyed via a transport device (10) to the first web (4), to which the piece of material (2) is attached by means of ultrasonic welding over a limited attachment area (5) on the pieces of material (2), and the pieces of material (2) are subsequently fixed to the material web (4) by ultrasonic welding in a second station (6). The second station comprises an ultrasonic horn (18) at a fixed distance from a stay (19) designed as a rotating drum with a patterned outer surface.
