Definitions

• the present invention relates to the field of hygiene and more particularly to that of feminine hygiene.
• the wings or side flaps further comprise one or more folds, welded together, improving the lateral seal.
• the fixing of these wings is ensured by the cutting mode because they are an integral part of the towel.
• the device according to the invention aims to obtain this desired new result.
• the side flaps according to the invention have a triangular surface extending over the median axis of the outer part of the period towel which may include at its base, a semi-circular notch.
• the two side flaps are mounted head to tail on the towel, so as to offer the widest possible adhesion surface.
• the flaps are lateral and are folded under the adhesive surface (s) of the single-sided silicone, placed on the internal surface, which allows the subsequent transfer of the adhesive surfaces to the lateral flaps during use.
• the invention also includes a process for the production of hygiene articles lined with these side flaps which consists of trapping the absorbent pad formed of cellulose pulp or composite of the sanitary napkin, between a film of polyethylene and a layer of non-woven fabric or microperforated polyethylene film, watertight towards the outside, to liquids, which the two films are sealed by welding or by gluing, which the previously formed fabric, formed from the strip, is cut by the pad and the two protective layers of waterproof film by forming a corrugated ribbon in the form of a garland, which is deposited on this garland a single-sided silicone paper whose internal face has been previously coated in a continuous or discontinuous manner d 'glue. A second single-sided silicone paper with the internal side previously coated one or more blocks of glue is deposited on the side flaps previously folded on the internal face.
• the sealing of the polyethylene film is carried out by heat sealing or by gluing.
• an elastic cylindrical membrane maintained under pressure ensures contact between the two layers of film for sealing.
• the cutting of the side flaps is done synchronously and in phase with the installation of absorbent pads.
• the removal of the single-sided silicone paper takes place after the ribbon has been cut into a garland.
• the removal can also be carried out before cutting the garland.
• FIG. 1 there is shown seen from the front a periodic towel having two side flaps arranged asymmetrically and folded over the inner face of the periodic towel.
• Figure 2 shows the two side flaps deployed for use shown with each an adhesive surface (5) and (5 '). According to various embodiments of the invention, these adhesive surfaces can either be wider to occupy part or all of the side flap, or even be in the form of several glued and offset surfaces.
• Figure 2 also shows the notches (3) and C3 ') on the one hand and (4) and (4') on the other hand, highlighting the advantage of these surfaces for ensuring deployment full of shutters.
• Figure 3 shows an enlarged view of the overlap of the two side flaps when they are folded down, or their asymmetrical arrangement relative to the axis of symmetry of the sanitary napkin when they are deployed.
• the triangle determined by the side edge of the flap and the edge of the polyethylene and nonwoven fabric veil or upper veil has an apex angle of approximately 50 °, while the angle at the apex of the same triangle when the side flap is folded over the towel is about 80 °.
• the invention also consists in making a kit adaptable to all existing manufacturing machines, using traditional manufacturing methods shown diagrammatically in FIGS. 4, 5 and 6.
• the kit therefore comprises, first of all, an unwinder and folding machines making it possible to cover or coat the absorbent mass of this additional fabric to improve the diffusion.
• the second modification of the machines consists of mounting a calendering stand to limit leakage on the sides of the product.
• the shape of the calendering is very important.
• the pad or absorbent mass (8) is therefore produced with its diffuser (9) and can make it possible to continue the manufacturing process which is carried out by continued.
• the pad when finished, is deposited on polyethylene (6) or on nonwoven (or microperforated film) which has been previously glued for this operation.
• the kit therefore contains a gluing system (10) as well as a stand (22) for unwinding the material regularly in order to have the desired tension and a bar feeder system (23) allowing the film to be regulated and unfolded .
• the sheet thus produced can then undergo the compression treatment (24) of the assembly to obtain good cohesion.
• FIG. 6 shows the fixing of the two waterproof strips (14) and (14 ') on which the permeable film is adjusted.
• the mounting kit therefore also comprises a continuous or intermittent cutting station (15) which allows the production of the lateral fixing lugs (the kit allows to make from 1 to 10 lugs depending on the end use of the product) .
• These legs can be asymmetrical or symmetrical (14) and (14 ').
• the scraps are sucked up and collected in bags.
• One or more single-sided silicone papers (16) coated with glue on one side (17) are deposited on the sheet.
• the kit therefore also includes the system for removing and unwinding the silicone paper (16) and (16 ') as well as the sizing material (17) and (17').
• the problem which then arises consists precisely in folding down the legs and applying the blocks of glue to the legs using silicone paper.
• the kit according to the invention also includes a folding stand (25), a compression station (24) and a station for cutting silicone paper (26). Once the product is finished, all you have to do is cut it to the final length, fold it and pack it individually or leave it flat for use.
• the towel therefore has a silicone paper on the outer face as well as on the tabs on the inner face.
• the silicone paper is first removed from the external face to apply it to the bottom of the panties and, secondly, only the silicone paper located on the fixing tabs.
• the periodic towel according to the invention can thus be used with only 4 manipulations whereas for a model with 2 symmetrical fastening tabs, the number of manipulations is significantly higher.
