摘要： A method of elastifying a non-woven or plastic jacket of a pants-type article in its unassembled hour-glass form, arranged end-to-end in a longitudinal web, comprises: stretching a web length of elastic net, film or elastomeric non-woven material, which is rectilinear in its unstretched state, transversely but not longitudinally at the two end portions (13) which will form the waist, stretching said length of elastic net, film or elastomeric non-woven material longitudinally but not transversely at the intermediate crotch portion (14) therebetween, whereby the net or film will naturally assume the desired hour-glass shape of the jacket to be elastified, then bonding the stretched net or film in its hour-glass shape to the jacket (5).

摘要： A diaper or incontinence guard that includes a waist belt (1) and an absorbent unit (2) comprising a front part (3), a rear part (4) and an intermediate crotch part (5), and fastener devices (9-11 and 6-8 respectively) which are disposed at the front and the rear end of the absorbent unit and which can be fastened to said belt. According to the invention, each of the front and the rear ends of the absorbent unit (2) includes a respective central fastener device (10 and 7) that is located on the longitudinal symmetry axis (A-A) of the unit, and two lateral fastener devices (9, 11 and 6, 8 respectively) located on respective sides of the axis.

摘要： The present invention relates to a disposable, absorbent pants-type diaper which includes a front-part (1), a back-part (2), a crotch-part (3) between the front and back parts (1, 2), at least two side-closure parts (12, 13) which mutually join parts of the side-edges (4, 5) of respective front and back parts, so that the pants will present a waist opening (9) and two leg openings (10, 11), wherein the diaper pants further include an elongated absorbent pad (14) having a front and a rear end-part (17, 18) and an intermediate centre-part (19), an inner casing layer (15) placed on that side of the absorbent pad (14) which is intended to face the wearer in use, and an outer casing layer (16) which is placed on the other side of the absorbent pad. The invention is characterized in that at least one of the respective front and back parts (1, 2) has at least one elastically stretchable regions (29, 30); in that the crotch-part (3) is essentially non-stretchable in relation to the stretchable region (29, 30); in that at least one of respective end-parts (17, 18) of the absorbent pad (14) is disposed within one of the elastically stretchable regions (29, 30), while the centre-part (19) of the absorbent pad is disposed within the relatively non-stretchable crotch-part (3) of the pants, whereby those forces that are exerted by the elastically stretchable region (29, 30) on the end-part or end-parts (17, 18) of the absorbent pad will function to hold the absorbent pad (14) in sealing abutment with the wearer when the diaper is worn.

摘要： The present invention relates to absorbent pants (1; 51; 111) having a waist opening (2) and two leg openings (3, 4), in which the pants comprise a pant's layer (5), which during use of the pants is intended to face the body of the user, and an outer barrier layer (6; 52, 53), which is waterproof and arranged outside the pant's layer (5) seen in the direction from the body of the user during use of the pants. The pant's layer (5) has a surface area which is greater than that of the outer barrier layer (6; 52, 53) and is joined in parts with itself or comprises means for enabling it to be joined in parts with itself, so that during use of the pants it alone constitutes the waist opening (2) and leg openings (3, 4) of the pants, and that the load-bearing parts of the pants and all of the parts lying against the body of the user hereby are formed only from the pant's layer (5). The pants are also elastic, where the outer barrier layer (6; 52, 53) is essentially inelastic, while the pant's layer (5) contains all the elasticity of the pants in the form of an elastic means (20).

摘要： In a method of applying a thread to a moving substrate, a thread is continuously dispensed to a pick-up point at the point of contact between two rotating wheels (2, 3) inclined towards each other and provided on their peripheries with fingers (7) which hook the thread and move it to one side or the other as they rotate, and then deposit the thread extended between said fingers 180° from the pick-up point. Long spaces between the fingers (7) on one wheel or the other make it possible to lay the thread longitudinally (8b) or in a long diagonal line instead of merely in a lateral zig-zag pattern. The invention also relates to devices for carrying out said method.

摘要： Disclosed are panty briefs, primarily intended for the fixation of a diaper. Interknitted in the waist portion (5) of the briefs are elastic threads (11, 11') generally extending in the circumferential direction of the waist portion. These elastic threads produce an elastic contraction in the circumferential direction of the briefs in order to establish a tight fit depending on the size of the wearer. In order to obtain the best possible fit for large and small wearers, the elastic threads (11) only form meshes with the base web of the briefs along a portion of the extension of these threads (11) in the circumferential direction of the briefs. This causes the waist portion of the briefs to appear with undulations allowing improved adaptation to large and small wearers without the risk of irritating local pressures.

摘要： The invention relates to absorbent articles, such as diapers and like articles and is concerned with methods for preventing undesirable odours and/or preventing the growth of undesirable microorganisms when the articles are in use, and also provides an absorbent article which can be worn for long periods of time without generating undesirable odours, incurring the risk of infection or having a negative effect on skin. Another object is to amplify the presence in the wearer's urogenital zone of microbiological flora that will assist in preventing the occurrence of urinal tract infections. These objects have been achieved by adding to the absorbent articles microorganisms which exhibit antagonistic properties against present undesirable strains of microorganisms, so as to restrain the growth of these or establishing of new undesirable species.

摘要： The present invention relates to an arrangement for air-laying on a moving air-permeable conveyor path (2; 7; 12) fibre bodies that have a profiled cross section transverse to the movement direction (A) of the conveyor path, wherein the arrangement includes at least one air-laying unit having means for delivering a stream of air-carried fibres to a region above the moving conveyor path; means (3; 8; 13, 14) for subjecting the stream of air-carried fibres in the delivery region to a subpressure beneath the whole of that part of the conveyor path located in the delivery region; and means (4; 5; 9, 10) for delimiting the stream of air-carried fibres from ambient air. According to the invention, the means for delimiting the stream of air-carried fibres includes at least one part (b; 9) which coacts with the air-permeable conveyor path and which has smaller dimensions transverse to the direction of movement than the air-permeable conveyor path.

摘要： The present invention relates to a method for ultrasonic welding of material webs (5, 6) which move between an ultrasonic horn (2) of an ultrasonic welding arrangement and an anvil holder (3) having a determined pattern of anvils (4), so as to enable the webs to be welded at high web speeds. According to the invention, the weld width of each ultrasonic horn (2) in the ultrasonic welding arrangement is determined in accordance with the intended highest travel speed of the webs (5, 6). The invention also relates to an arrangement for carrying out the method.
