Problems solved by technology
[0003] Since in diapers of the type mentioned at the outset or in special incontinence products it is possible to have side parts that extend to a large extent in the direction of the hips, the production of the product is especially transverse to the direction of the hips, that is to say in the longitudinal direction of the product. , becomes very difficult in fast-moving manufacturing machines, because at high speeds the material forming the side parts cannot be guided correctly in the manufacturing machine or can only be guided with great effort

Embodiment Construction
[0032] figure 1 and 2 show the various folded states of the diaper 2 to be manufactured in the manner according to the invention. The diaper 2 comprises a diaper main body part generally indicated by reference numeral 4, which is also often referred to as a chassis. The main body portion 4 comprises a front region 6, a back region 8 and therebetween a crotch region 10 which is located between the legs of the wearer when the diaper 2 is worn on the wearer. The main body part 4 also comprises an absorbent body 12 which is dimensioned in a suitable manner for receiving and permanently storing body fluids. The absorbent body 12 is generally reinforced by a liquid impermeable layer 14 which can also form the outer visible side of the incontinence article. Furthermore, the absorbent body 12 is usually covered by a liquid-permeable layer 16 (outer liner). Also shown are elastic elements 18 extending on both sides of the absorbent body 12 , which can comprise a material that is str...

The disclosure relates to a method for the production of a diaper having a main part comprising a front region, a back region, and a crotch region located there between that comes to rest between the user's legs in the longitudinal direction, and side sections attached on both sides. The method is characterized in that a material web forming the side sections is supplied in the longitudinal direction; the material recesses for attaining an oblique course or contouring of the side sections are formed by placing an opening with a continuous circumferential edge in the material web; the material web is then divided in the longitudinal direction and said separation runs through the opening; sections are removed from the two partial webs transversely to the longitudinal direction in order to form the side sections to be applied on both sides; and the sections are attached to the respective back region and / or to the front region.
Description
technical field [0001] The invention relates to a method for the manufacture of a diaper having a body part consisting of a front area, a back area and a crotch area between them in the longitudinal direction and between the legs of the user, wherein the main body part comprises an absorbent body; side parts connected on both sides to the back area and / or the front area, said side parts extending outwards beyond the side longitudinal edges of the main body part in the transverse direction and in the worn state of the diaper The front area and the back area are connected to each other, wherein the side parts are formed to extend obliquely to the longitudinal direction at least on the side facing the crotch area, or are formed in a form, wherein the diaper is produced in its longitudinal direction and in order to achieve the oblique orientation of the side parts Extended or formed to create a material gap in the side portion. Background technique [0002] Such diapers are kno...
