Description
La présente invention se rapporte à un procédé de fabrication de tamponsThe present invention relates to a method for manufacturing buffers

Une difficulté rencontrée lors de la fabrication de tampons absorbants consiste à obtenir un pouvoir absorbant suffisant des fluides corporels, sans que le tampon absorbant soit pour autant trop volumineux et encombrant. Une autre difficulté consiste à donner au tampon une forme adaptée correspondant à celle du corps et recherchant le confort de l'utilisateur. Pour surmonter la difficulté citée en premier lieu, 1.5 il a déjà été proposé d'améliorer le pouvoir d'absorption des tampons absorbants par l'incorporation de moyens ou substances A difficulty encountered in the manufacture of absorbent pads is to obtain sufficient absorbency of the body fluids, without the absorbent pad being too bulky and bulky. Another difficulty is to give the tampon a suitable shape corresponding to that of the body and seeking the comfort of the user. To overcome the difficulty mentioned above, 1.5 it has already been proposed to improve the absorption capacity of absorbent pads by the incorporation of means or substances.
dits "hyper-absorbants".so-called "hyper-absorbent".
Lorsqu'elle a été mise en pratique, cette proposition n'a pu jusqu'à présent être concrétisée qu'avec des tampons absorbants consistant en une matière floconneuse en forme de bande. A cette fin, la matière hyperabsorbante est déposée sur la bande, le plus souvent par saupoudrage, après quoi la bande est repliée sur elle-même. Il en résulte une sorte de sandwich sans fin à l'intérieur duquel se trouve une couche When put into practice, this proposal has so far only been realized with absorbent pads consisting of a strip-like fluffy material. For this purpose, the hyperabsorbent material is deposited on the web, usually by dusting, after which the web is folded back on itself. The result is a kind of endless sandwich inside which is a layer

L'exigence d'une forme adaptée à la configuration du corps peut être satisfaite soit par le sectionnement, le pliage et la compression compliqués d'une bande de matière f]oconneuse, soit, d'une maniere plus simple, par moulage des The requirement of a shape adapted to the configuration of the body can be satisfied either by the complicated cutting, folding and compressing of a strip of fibrous material, or, in a simpler way, by molding of

Un tel tambour aspirant consiste pour l'essentiel Such a suction drum essentially consists of

The bottoms of the molding cells are made

La matière floconneuse, consistant le plus souvent en une substance cellulosique fractionnée dans des moulins appropriés, est rapprochée à l'aide d'un courant d'air de la surface supérieure du tambour aspirant, elle est ensuite aspirée par les fonds perforés des alvéoles de moulage, puis comble pour finir ces alvéoles. Au cours d'une intervention consécutive, un excédent de matière floconneuse aspirée est raclé, par exemple au moyen de brosses rotatives, et l'on The fluffy material, usually consisting of a cellulosic substance fractionated in suitable mills, is brought together with a stream of air from the upper surface of the suction drum, and is then sucked up by the perforated bottoms of the honeycomb cells. molding, then fill to finish these cells. During a subsequent intervention, an excess of fluffed material sucked is scraped off, for example by means of rotating brushes, and

Cependant, les tampons absorbants fabriqués de la sorte ne disposent que d'un pouvoir d'absorption des fluides corporels, prédéterminé par la quantité de flocons However, the absorbent pads made in this way have only a power of absorption of body fluids, predetermined by the amount of flakes

L'invention a par conséquent pour objet de proposer un procédé de fabrication de tampons absorbants en matière The object of the invention is therefore to propose a method for manufacturing absorbent pads made of

Le premier objet cité de l'invention est atteint par le fait qu'on délivre simultanément au tambour aspirant, dans des régions situées les unes derrière les autres dans The first mentioned object of the invention is achieved by the fact that it delivers simultaneously to the suction drum, in regions located behind each other in

En outre, la quantité de matière floconneuse délivrée à la première zone peut être dosée de façon qu'elle comble environ 1/3 de la hauteur totale des alvéoles de moulage. La seconde partie de l'objet de l'invention est In addition, the amount of fluffing material delivered to the first zone can be metered so that it fills about 1/3 of the total height of the molding cells. The second part of the subject of the invention is

Le procédé selon l'invention, pour fabriquer des tampons absorbants qui sont moulés à la forme du corps et présentent un noyau en matière hyperabsorbante, consiste pour l'essentiel à introduire une première couche de matière floconneuse dans des alvéoles de moulage en mouvement; à déposer ou à saupoudrer sur cette couche une couche de matière hyper-absorbante; et, pour finir, à combler intégralement The process according to the invention, for producing absorbent pads which are molded to the body shape and have a core of superabsorbent material, essentially consists in introducing a first layer of flocculent material into moving molding cavities; depositing or sprinkling on this layer a layer of hyperabsorbent material; and, finally, to fully fill
