  • Publication number: 20170007470
    Abstract: The invention relates to a sanitary article, with an absorption body (10) and with leg openings, wherein elongate elasticating means (12) curved in an arc shape are fixed on both sides outside the absorption body (10) in the product transverse direction (16), resulting in elastication of the leg openings (18), wherein a planar material portion (6) facing towards the body comprises a nonwoven (8), characterized in that the nonwoven (8), in the area of the elasticating means (12) on both sides, and for fixing the latter, has, on its side (22) facing away from the body, a first adhesive coating (24) applied in a strip shape over the whole surface and extending in the product longitudinal direction (14), and in that the nonwoven (8), in the area of the elasticating means (12) on both sides, and for fixing the latter, has, on its side (22) facing away from the body on both sides in the product transverse direction (16) outside the first adhesive coating (24), a second adhesive coating (26) applied in a strip shape

  • Patent number: 9138937
    Abstract: A disposable hygiene article (2), such as an incontinence diaper or incontinence pad has a composite non-woven fabric (38) that is provided with at least one cuff element (16) and a non-woven fabric or film component (10, 12). The cuff element (14) is attached to the non-woven fabric or film component (10, 12) in at least some areas by means of a joining pattern (36) encompassing discrete ultrasonic welding points (30) in order to form the composite non-woven fabric (38). At least some sections of the joining pattern (36) are curved. The joining pattern has a maximum index (I) of variation of the ultrasonic welding points of 40 percent. An area seized by the welding points has a density within the joining pattern which decreases in rear and front end portions along endwards directed and inwardly curved extensions of the joining pattern.

  • Publication number: 20100059067
    Abstract: A disposable hygiene article (2), surgical covering item, or surgical garment, such as an incontinence diaper, incontinence pad, surgical drape, or surgical coat, has a composite non-woven fabric (38) that is provided with at least one non-woven fabric component (16) and another non-woven fabric or foil component (10, 12). The first non-woven fabric component (14) is attached to the other non-woven fabric or foil component (10, 12) in at least some areas by means of a joining pattern (36) encompassing discrete ultrasonic welding points (30) in order to form the composite non-woven fabric (38). The joining pattern (36) extends in a first direction (32) and a second direction (34) that runs perpendicular thereto, the distance in the first direction (32) being longer than the distance in the second direction (34). At least some sections of the joining pattern (36) are not rectilinear.

  • Publication number: 20080208152
    Abstract: An absorbent incontinence product with a main piece formed of a front section, a back section and a crotch section which lies in a longitudinal direction between the front and the back sections and is intended to be placed between the legs of a user. The main part has an absorbent body and first material sections which are attached to the back section and/or to the front section and extend in the transverse direction over first longitudinal side edges of the main piece and second material sections which are attached to the back section and/or to the front section and extend in the transverse direction over second longitudinal side edges of the main part. The first and second material sections connect the front section to the back section when the product is applied.
