The present invention relates to a method for the production of an absorbent disposable incontinence diaper (2), with an absorbent body (12) having a main part (4), comprising a front portion (6) with longitudinal lateral front edges (42), a back portion (8) with longitudinal lateral back edges (41) and a crotch portion (10) arranged in-between, placed between the legs of the wearer, and with lateral back portions (20) bilaterally attached to the back portion (8) and lateral front portions (22) bilaterally attached to the front portion (6), which extend in transverse direction (30) of the disposable incontinence diaper (2) beyond the longitudinal lateral front and/or the back edges (42, 41) of the main body (4), and are spaced apart from one another in the longitudinal direction (28) of the disposable incontinence diaper (2), where the lateral back and front portions (20, 22) may be detachably connected to one another to apply the disposable incontinence diaper (2), where a continuous or quasi-continuous separation process including the lateral back portion (20), the main part (4) and the lateral front portion (22) is implemented to contour the bilateral leg opening areas (50) of the disposable incontinence diaper (2), so that a connected offcut (62) is formed by the lateral back portion (20), the main part (4) and the lateral front portion (22) which has to be conveyed away, characterized in that the offcut (62) is gripped and conveyed away by a transfer roller (100) having pin-, needle-, knob-, hook- or barb-shaped mechanical elements (102) protruding from its surface (104).
L'invention concerne un procédé de fabrication d'une couche jetable d'incontinence absorbante (2), avec des parties latérales arrière (20) rattachées des deux côtés à la partie arrière (8) et des parties latérales avant (oreilles) (22) rattachées des deux côtés à la partie avant (6), qui s'étendent dans une direction transversale (30) de la couche jetable d'incontinence (2) au-delà des bords longitudinaux latéraux avant et arrière (42, 41) de la partie principale (4), et qui sont espacés l'un de l'autre dans une direction longitudinale (28) de la couche jetable d'incontinence (2). Pour réaliser le contour de parties d'entrejambe (50) des deux côtés, on effectue une opération de séparation, à chaque fois de chaque côté, en continu ou presque, sur la partie latérale arrière (20), la partie principale (4) et la partie latérale avant (22), de sorte qu'une chute (62) soit formée à partir de la partie latérale arrière (20), la partie principale (4) et la partie latérale avant (22) ; le procédé est caractérisé en ce que la chute (62) est saisie et évacuée par un rouleau de transfert (100) par des éléments (102) mécaniques saillants de sa surface (104), en forme de broches, boutons, crochets ou barbes.
