Definitions
- the present invention relates to the field of hygiene and more particularly to that of feminine hygiene as well as that of incontinence in children and adults.
- the device according to the invention also allows a very considerable saving of space by making production benches of very small size.
- Hygiene products and in particular periodic towels, panty liners, baby diapers, devices for incontinence of adults and the elderly, are currently manufactured continuously by unwinding the absorbent material and by cutting to the shape of it in the longitudinal direction of the production bench. This way of working results in significant linear speeds as well as the need for frequent coil changes.
- a precise diagram of mounting of such a device is provided in the international patent application PCT / FR93 / 00671 published under the number WO 94/04110. It shows the drum for unwinding the absorbent material, the web of which unwinds in the longitudinal axis, then is sandwiched between two layers of film and, finally, is cut, piece by piece, always in the axis longitudinal of the conditioning bench and finally, pressed and heat sealed before packaging.
- the device according to the invention aims to remedy these drawbacks while ensuring the manufacture of high quality hygiene products.
- the device according to the invention is characterized by the fact that it successively comprises a reel with absorbent material followed by a wheel for forming the absorbent pad or mattress, the characteristic of which is to be disposed transversely with respect to the axis of the conditioning bench.
- the forming wheel is cylindrical in shape and carries on its surface a large number of molds or cutting cups so that the passage to the upper part of a counter knife rotating at the same speed will ensure cutting to shape desired hygiene items.
- the pad or absorbent mass is caught between two insulating films, made of polyethylene or any other inert material. These films can be glued beforehand to facilitate adhesion or to promote the optimization and cohesion of the product.
- the hygiene articles after cutting and packaging are passed through a cylindrical press which makes it possible to seal the periphery of the absorbent mass, possibly forming gathers at the edges.
- This cylindrical press could be arranged as in conventional production benches in the longitudinal direction, but it will advantageously be placed transversely on the production bench like the cutting member arranged upstream.
- These two characteristic elements of the invention are cylindrical in shape.
- the cutting elements are arranged at an angle ranging from 45 to 135 ° relative to the longitudinal axis of travel of the production bench. On the same cylinder, certain cutting elements can be placed at 90 ° and others, in another orientation.
- the dimensions and the final shape of the finished product are ensured by another cutting station having the same characteristics as the pad forming wheel, as the cutting of the pad and of the assembly press.
- the member ensuring the final cut can advantageously be placed transversely on the bench.
- the pad forming wheel has cutting shapes arranged at an angle which varies from 60 to 120 ° relative to the production bench, and mainly at an angle of 90 °. .
- the forming wheel (8) is in the form of a hard metal cylinder having two ends (9) (9) of reduced section, which are fixed on the stops of a drive axis arranged perpendicular to the production bench.
- the surface of the cylinder can carry as many cutting molds (10) (10 ') (10 ") as the surface can contain, taking into account the size of the hygiene article to be cut. In this way, the scraps absorbent material are brought to a minimum.
- the cutting cylinder turns outwards so that after cutting, the articles produced fall forward on the bench.
- the cutout shapes (1 1) are shown in Figure 3. They are shaped like a bean to form a female external protection device. It is obvious that the form of cutting can be very varied, so as to adapt exactly to the needs of the production of different hygiene articles.
- the cutting shapes can be presented along the generatrices of the cylinder, all parallel or, on the contrary, with cutting shapes placed one parallel and the other perpendicularly, so that the maximum positioning on the surface of the cylinder is thus occupied.
- the absorbent masses are formed of defibrated paper pulp (fluff) which is shredded after its unwinding at the entrance to the bench. This is then pressed again to give it a compact shape and, it is this mass which crosses the cutting wheel and which comes out cut to the required shape by detaching from the wheel and is collected on a subsequent part of the production bench.
- fluff defibrated paper pulp
- the final cutting station is also arranged transversely according to the same principle so that the assembled or heat-sealed hygiene articles leave ready for packaging at the end of the production bench.
- the cylinder or cylinders carried by the production bench according to the invention have dimensions adapted to the width of the bench. It is certain that the length of the cylinder can be varied within wide proportions, knowing that the longer the generators of the cylinder, the more it will be possible to cut or form hygienic articles by rotation.
- the cutting cylinder usually has an overall length of about 300 mm with an effective cutting surface of about 240 mm.
- Figure 2 shows a sectional view of the cutting cylinder (8), the cutting surfaces of the molds (12) (12 ') appear as sets of points (13) (13) arranged symmetrically two by two, over the entire surface of the cylinder.
- FIG. 3 shows a model of hygiene article after cutting using the device according to the invention.
- FIG. 4 shows the operation of the conditioning bench in which the female protective articles (5) (5 ′) after cutting are wrapped between two films (1) (2) made of insulating or inert materials, carried by reel drums ( 3) (4) and the final cutting of the article is ensured by a cutting station arranged transversely with respect to the conditioning bench to obtain different hygiene articles (7) fully conditioned.
- the invention also relates to the cylinder ensuring the cutting as described above as a necessary element of the device according to the invention.
- the subject of the invention is also articles of hygiene or feminine protection and, in particular, period towels, panty liners, diapers or articles for incontinence, as produced by the device according to the invention or by one of its variants obvious to the skilled person.
