Definitions
- the present invention relates to the field of non-tablecloths woven, consisting of fibers or filaments, intended, in particular but not exclusively, to be used for the production of articles hygiene, for example, for baby diapers or for adult incontinence or female protections. She relates more particularly to a method of perforating a non-woven web and a device suitable for implementing this process.
- the document EP-A-0214608 describes a method of perforation a nonwoven which specifically contains fibers or thermoplastic filaments.
- This process consists of perforating the sheet nonwoven by means of a plurality of needles which cooperate with a plurality of recesses. Under the action of needles, the fibers of the non-woven tablecloth are locally repelled and in order to preserve the vacuum thus formed, the studs and the contour of the recesses are heated so as to cause the fusion of the thermoplastic fibers. After hardening of the molten fibers, a perforation is obtained having the shape of the needle and whose contours are delimited and consolidated by fused fibers and therefore linked to each other.
- This method has the drawback, on the one hand of requiring the use of a nonwoven containing thermoplastic fibers and on the other hand, to bring a certain rigidity to the nonwoven due to the presence of hardened areas at the periphery of the perforations.
- the document EP-A-0974433 describes another type of process for perforation of a nonwoven web.
- the sheet is pushed by a perforating member inside an orifice opening out into a thin room so that the nonwoven web exceeds beyond this orifice.
- Organs of cut positioned inside the thin piece come then cut the fibers protruding beyond said piece so as to form perforations.
- the perforating member is a stud cylindrical with a hemispherical end, which is designed to be driven simultaneously in translation along its longitudinal axis and rotating on itself. This piercing member is not intended function of cutting the fibers or filaments of the web, this function being provided by the cutting members.
- This process requires a relatively complex device including a cylinder hollow whose interior is provided with cutting members and imposes the use of a thin piece in which are provided the orifices. In addition, this process does not guarantee perforations with a clear and reproducible contour in the time.
- the aim of the present invention is to propose a new method of perforating a nonwoven web of fibers or filaments which in particular overcomes all or part of the disadvantages associated with the use of the methods of the prior art.
- the process of the invention is known, in particular from the application EP-A-0974433, in that it brings the nonwoven web in contact with a perforated cylinder, and at least one perforation in the sheet by means of at least one perforation which is driven simultaneously in translation and rotation on itself.
- the Applicant has highlighted that the fact of putting using a sharp edge formed in plane (flat end surface of the insert), in combination with a perforating member driven in rotation on itself, advantageously allows to cut by shearing the fibers or filaments of the nonwoven web over the entire perimeter of the sharp edge, and thus makes it possible to obtain perforations with a sharp outline.
- a sharp edge formed in plane flat end surface of the insert
- a perforating member driven in rotation on itself advantageously allows to cut by shearing the fibers or filaments of the nonwoven web over the entire perimeter of the sharp edge, and thus makes it possible to obtain perforations with a sharp outline.
- the orifices of this cylinder in said external surface are not perfectly planar.
- the present invention also relates to a device for perforation of a nonwoven web which allows the implementation of the aforementioned perforation method of the invention.
- the device 1 designed for the perforation of a nonwoven web comprises a first cylinder 2 which is a perforated cylinder. This cylinder 2 is rotated (arrow F) around its longitudinal axis 3.
- the device 1 also comprises a second cylinder 4 driven in rotation (arrow F ') about its longitudinal axis 5 parallel to the axis 3 of the first cylinder 2.
- the first perforated cylinder 2 has on its periphery exterior a cylindrical part 6 provided with a plurality of 7 through holes. These perforations 7 are aligned according to the axis of the cylinder in the form of parallel rows distributed over all the periphery of the cylinder. Each hole 7 is equipped a removable insert 8 which will be more fully described with reference to Figure 2. In another alternative embodiment, the part 6 could be deleted and replaced directly by the perforated wall of the cylinder 2.
- the second cylinder 4 is provided on its periphery with studs 9 which are arranged to cooperate with the inserts 8 of the perforations 7 made in the outer part 6 of the first cylinder 2.
- cylinder 2 has also a fixed suction zone A which is delimited by the walls A1 and A2, and which allows the sheet N to be pressed against the first face 6a of the part 6 and to evacuate the pieces M of the tablecloth that have been cut out.
- each insert 8 comprises a body 8a provided with a recess (or perforation) 8b having a section circular.
- This recess 8b is through in the example shown, but could also according to the invention have a background, to the opposite of its external orifice 8i.
- the external surface 8c of the body 8a is equipped with a thread 8d which cooperates with a reverse thread 7a made inside each perforation 7 in order to fix each insert 8 in a perforation 7.
- the body 8a has at one of its ends a flange 8e having a flat external surface (S), into which opens the recess 8b (orifice 8i).
- the 8th flange can advantageously serve as a gripping means for fixing or removing the inserts 8 in the perforations 7.
- the insert 8 does not have a flange 8e and the recess 8b opens out at a flat end 8h of the insert.
- Such an insert presents well a sharp edge 8g formed by the intersection of the internal surface 8f of the perforation 8b with the end 8h of the insert 8, which 8h end forms a flat surface (S), which corresponds to the thickness of body 8a.
- the perforations 7 have a increasing diameter from the first face 6a of the part 6 towards the second face 6b of the latter; the recess of each insert 8 has an increasing diameter from the sharp edge 8g.
- the flared shape of the resulting recess 8 makes it easier to remove the pieces M of the recesses 8b.
- This additional feature can also be applied to a variant with flanged inserts, like the one in Figure 2.
- the pad 9 is mounted in an outer part 10 of the second cylinder 4 via a housing 11 at the bottom of which is a spring 12.
- the stud 9 is a axis cylinder 9a which is arranged in the housing 11 so that it turns on itself (along its axis 9a) when it moves in the direction arrow H (i.e. in a direction parallel to its axis of rotation and in the opposite direction to the perforated cylinder 2). More precisely the stud 9 is provided with a pin 13 projecting inside of the housing 11, this pin penetrating into a slide 14 formed in the wall of the housing 11 and which is inclined relative to the direction H of displacement in translation of the pad 9.
- the pin 13 is correlatively moves in the slide 14. Due to the inclination of the slide 14, the stud 9 performs a slight rotation on itself in a first direction of rotation R1 during its displacement in translation in the direction H, and in a second direction of rotation R2 during its displacement in the direction G opposite to H, i.e. in the direction of the perforated cylinder 2.
- the thread 8d equipping each of the inserts 8 is such that the displacement in rotation in the R1 direction of the studs 9 tightens the fixing of each of the inserts 8 in the perforations 7.
- the stud 9 has a rounded end 9b, of the type hemispherical, and a diameter D slightly larger than the diameter d orifice 8i of the recess 8b of the insert 8, so as to be able press the sheet N between said hemispherical end 9b and the edge vivid 8g of insert 8, which makes it possible to locally cut the tablecloth NOT.
- the two cylinders 2 and 4 are rotated (arrows F and F '/ Figures 2 and 3), being synchronized with each other by such that the hemispherical end 9b of a stud 9 comes apply precisely to the sharp edge 8g of the insert 8 with which it cooperates to locally perform a perforation in the sheet N.
- the stud is simultaneously rotated in the opposite direction R2 to R1 (second phase / plot on the right in Figures 2 and 3).
- the end of the stud 9 penetrates slightly inside the recess 8b of the corresponding insert 8, by locally pushing back the portion (P) the tablecloth N located at the right of said recess 8b, and presses said portion (P) of sheet against the sharp edge 8g.
- the hemispherical end of a stud 9 being of a diameter D greater than that d of the recess 8b, and the edge 8g in a flat area (flat surface S of the 8th flange or 8h end of the insert), the N sheet is therefore locally compressed against the sharp edge 8g and thus cut by shearing fibers or filaments constituting the N sheet, under the actions combined rotation (in both directions of rotation R1 and R2) of the pad 9 and pressure between this pad 9 and the edge 8g.
- each insert 8 has a surface (S) which is flat.
- the plaintiff has evidence that when the surface of the 8th flange that comes into contact with the tablecloth N is not strictly flat, but is by slightly curved such as for example that the surface of the cylinder perforated 2, it seems, without the plaintiff being bound by this explanation, that it is not possible to get a contact sufficient between the end of stud 9 and the entire perimeter of the sharp edge 8g, so it is not possible to press uniformly and sufficiently the tablecloth N against the sharp edge 8g of insert 8, to obtain the cutting of an integral portion (P) of tablecloth.
- the invention advantageously makes it possible to produce in the sheet non-woven perforations that have a sharp outline and reproducible, without the need to heat the filaments or of the tablecloth.
- the invention advantageously allows make perforations with a circular outline.
- a hydrophobic nonwoven web such as that frequently used for the realization of hygiene articles, it is important that the perforations made in this sheet are circular. Indeed, only circular perforations allow water or any other liquid to pass through the hydrophobic nonwoven without wetting the surface of the latter, which makes it possible to absorb a liquid while having a dry surface.
- the removable nature of the inserts allows advantageously to overcome at a lower cost the wear problems of inserts, and in particular their sharp edge 8g.
- an insert 8 When an insert 8 is, it just replace it with a new insert.
- the invention is however not limited to the use of inserts which are removable.
