Definitions

  • the invention relates to a method for producing a pile fleece covering by means of structural needling.
  • a preliminary product is first produced, consisting of a nonwoven fabric that is pre-consolidated by needling.
  • the structural needling is carried out by guiding the pre-fabric over a lamella grate from lamella webs oriented in the direction of the goods flow with gap gaps in between and intermittently piercing the pre-fabric with lifting needles that are aligned in rows with the gap gaps.
  • the flocks of fibers grasped by each row of needles are thereby pushed into the gap gaps of the slatted grate and produce pimples protruding from the base of the goods on a strip of goods extending in the direction of movement of the goods.
  • the knob density generated in a strip of goods depends on the working cycle of the needles and the speed of the goods. This is how the structural goods are made, which are treated with binders on the back of the goods in order to solidify the goods base. In order to give the textured goods a velor character, the tips of the polnubs are shorn on the front of the goods.
  • a rib structure of the pole knobs is formed, which extends in the direction of the goods pass.
  • the goods get a cord-like appearance.
  • the rib-forming pole knobs lie one behind the other in the direction of the ribs and can support one another, but there is a rib spacing transversely to this, which precludes such support here.
  • the goods also have different elongation characteristics in the longitudinal and transverse directions, which can impair the dimensional accuracy of the end products produced from this pile fleece. This is important because after being deformed and punched according to the contours, such fleece coverings are used for the interior of vehicles.
  • the rib structure also has an adverse effect on the imprinting process of this known covering; when walking on or after pressure, there is a high permanent settling of the pole knobs, which does not easily reform itself.
  • the present invention has for its object to develop a simple and inexpensive method for producing a pile fleece covering of the type described above, in which, however, a good support of the generated pile knobs is ensured, the impression behavior is improved and the product is advantageously dimensionally stable.
  • the pole knobs in the adjacent ear strip can now be placed so tightly that they can support each other with their bulk not only within a strip of goods, but also across it, towards the neighboring strip.
  • the slat webs run in the grate in the invention, not in a straight line, but are divided into two or more fields that are cross-offset to each other, where, if you look in the direction of the goods flow, they are alternately arranged with gaps in the gap, where there are free spaces in a field, because there are lamella webs are located, the knobs are being molded in a subsequent other field, while the knobs previously created are supported in this working phase on the lamellar webs there.
  • the pole knobs of a strip of goods are aligned approximately aligned with the free spaces of an adjacent strip of goods, which is particularly favorable for mutual support. Because of the oriented puncture of the needles in the different fields, it is important to form the pimples - with a local offset - but at the same time and in the same cycle.
  • the starting product for the pile fleece covering according to the invention are staple fibers. They are rolled up as a pile with the help of a cross-layer several times layered and mechanically consolidated into a pre-fleece by needling. Such preliminary goods 10 are now subjected to a special structural needling, which is to be described in more detail with reference to FIGS. 1 to 4, where the most important mechanical components for implementing the method are shown.
  • the treatment takes place in two fields 11, 11 ', which are realized here in two sections of a lamella grate 12 lying one behind the other.
  • An alternative would be to divide the two fields into several individual sections that lie in an alternating order.
  • 11 ' there are lamellar webs 13, 13', which are at a defined distance from one another and therefore close gap gaps 14, 14 'between them.
  • the lamellar webs 13, 13 ' serve as a support surface when carrying out the preliminary goods and extend in the direction of the goods pass 15, which is marked in FIG. 1 by an arrow.
  • each row of needles 17 and 17 ' is aligned with one of the gap gaps 14 and 14' in the associated fields 11, 11 '.
  • the peculiarity lies in the fact that the lamella webs 13 of one field 11 are aligned with the gap gaps 14 ', as is shown by the assignment arrows 19 in FIG. 1; and vice versa, the webs 13 'of the rear panel 11' are aligned with the gap gaps 14 of the front panel 11.
  • all the needles 16 are jointly movable in a stroke - in the sense of the movement arrow 21 shown in FIGS. 3 and 4 - in a needle bar 20.
  • the leg ends 22 pass through the openings 23 of the stripping plate 24, bump into the fleece 1 0 , capture a hinge of fibers of the preliminary fleece on the way of their piercing movement and press it out on the underside 25 of the fleece 1 0 , into the gap gaps 14 of the Lamellar grating 12 in this first field 11.
  • the height of the knobs 26 can be influenced, which is usually in the range from 4 mm to 8 mm.
  • the thickness 28 of the needles 16 in the shaft area is 1 mm.
  • the division in the grate 12 is only 3 mm, with 1 mm for the width of the respective web 13 or 13 'and 2 mm for the clear width 29 of the gap gap 14 or 14'. 1, 3 and 4 are therefore not drawn to scale.
  • the web width 31 indicated in FIG. 3 cannot be selected to be smaller, nor should a division of less than 3 mm, indicated in FIG. 3, of approximately 3 mm be used, so that, starting from the structural needle 15, one that is necessary for reasons of strength Strength 28 still acceptable amounts of fiber material detected and pressed out to the knob 26. With narrower divisions 3o, the knobs are too weak.
  • FIG. 5 shows a section of a known structural product 32, which is generated by a continuous row 17 of structural needles 16, which are not in the different fields 11, 11 ', which are characteristic of the invention, but are designed to be continuously aligned.
  • a rib structure 33 results in the relevant product strip 27, in which the nub density within the rib 33 depends on the aforementioned operating sizes.
  • the spacing sequence 34 is satisfactorily narrow, as is indicated by the fiber pad 35 indicated by circular lines in FIG. 5, which forms the pressed-out pile studs 26 on the underside of the goods.
  • the puncture area of the needle is marked there as a central circular disk 36.
  • the outline of the fiber bundle 35 detected during the needling of the structure is oval, with an axis oriented in the direction of the article passing through.
  • the tufts 35 are adequately supported at the selected knob density 34, but empty lanes 37 are formed between the ribs, where the ribs 33 are at a distance 38 from one another, which provides effective mutual support of the pole knobs 26 with respect to the Excludes goods width.
  • the known goods 32 do not behave favorably under pressure.
  • the properties of the goods to tensile stress in the longitudinal and transverse directions 39 4 0, each indicated by the arrows in Figure 5 are different, which would lead to poor dimensional stability of the goods 32nd
  • FIG. 6 shows in cross section the structure of the slatted frame 12 in a front and a rear section, the same being used to designate corresponding components Reference numerals, as in the previous description of the invention according to Fig.1 to 4, have been used. It can be seen that the disturbing lane formation 37 is caused by the inevitable web width 31 of the uniform lamella grate 12. It is not possible to bring these web widths 31 to zero in order to reduce the disturbing distance 38.
  • FIG. 8 again illustrates in cross section the conditions in the two fields 11, 11 ', as have already been described in connection with the preceding FIGS. 1 to 4. These conditions also exist when the pile fleece covering 42 according to the invention is produced according to FIG. 9, as can be seen from the identical structure of these components between FIGS. 8 and 10.
  • the Fig.7 was developed from the needle penetration density, as has been explained, from Fig.5. While it does not make sense according to FIG. 5 to achieve a greater nub density by reducing the spacing sequence 34 of the needle punctures 36 - because only the rib structure 33 would be more pronounced - the situation is different according to FIG. 7. 35 ', because of the low knob density selected here, free spaces 43 are formed, if desired, could easily be reduced or even completely eliminated by a higher knob density in the inventive strips 27, 27'. The latter is shown in Fig.9. Because of the same structure in the slats rust 12 and in the arrangement of the two rows of needles 17, 17 ', the width of the aforementioned strips 27, 27' is the same as in Fig. 7.
  • the spacing sequence 44 of the knobs 26 or 26 'in a goods strip 27 or 27' is brought to the smaller value 44 ', so that there is no horizontal support only in four directions but a mutual contact of the molded-out pole knobs 26, 26 'results all around.
  • the dimensional accuracy is consistently good due to the uniform construction on all sides.
  • the impression behavior of the covering 42 is almost ideal. If the tips of the pile nubs 26, 26 'are cut off, so that the fiber ends are exposed to the face, one has the impression of a closed velvet-like velor. There is no longer any evidence of rib formation.
  • the two lamella web sections 13, 13 ' are supported by a central frame spar 45, as is done by the end spars 46, 47.
  • the central spar 45 results in a particular stability in the central area and also ensures a perfect offset 18 of the webs 13, 13 'on both sides. It is important to bring the two fields very close together.
  • the two fields 11; 11 ' are divided into sections and connected in series with one another in an alternating sequence. For an exact puncture sequence, it is important to make the punctures in the two fabric strips 27, 27 'as closely as possible one after the other and for this purpose to use a needle bar 20 which can be moved up and down and which positions the individual needles 16 exactly with respect to one another.
  • the webs 13, 13 'on both sides could also be gripped directly between one another and thus fastened to one another. In the latter case, the web then forms the clear width of the gap gap in the adjacent field.
