Definitions

  • the invention relates to a sawtooth wire for rollers of spinning preparation machines, such as cards, in particular a sawtooth wire for a spool.
  • Such sawtooth wires are usually produced as strand material, optionally rolled up on transport rollers and, for use, drawn helically or helically along an outer circumference of a corresponding roller, for example a tambour roller. Rollers formed in this way are used for a wide variety of purposes. There are cleaning rollers designed to separate incoming fibrous material from impurities such as cotton boll material. Other sawtooth wires, on the other hand, are designed to loosen fibers and parallelize them, as is the case, for example, with the tambour rollers of cards. In the case of intermediate rollers in a processing chain, there is a need to remove fiber material from an upstream location and deliver it to a downstream location, and to do this at the highest possible speed.
  • a deepest area between two teeth usually the transition area between the tooth face of one tooth and the tooth back of the next tooth (hereinafter referred to as the tooth gap) in the row of teeth of the sawtooth wire, has transverse to the longitudinal extent of the sawtooth wire seen when stretched out, a distance from a bearing surface of the sawtooth wire on the roller which is sufficiently small to be able to bend the sawtooth wire so that it can be wound around the associated roller as described above and so mounted on that roller.
  • fibers tend to accumulate in this transition area and thus have the effect that fiber material that can be used per se does not reach further processing, ie, for example, is not removed from a removing roller.
  • the object of the invention is to at least reduce this disadvantage. This object is solved by the subject matter of claim 1. Advantageous developments of the invention are specified in the dependent claims.
  • a sawtooth wire which is set up to be drawn helically or helically onto a roller of a spinning preparation machine along an outer circumference of the roller and essentially transversely to its axis of rotation.
  • the sawtooth wire is preferably produced in a known manner as a strand material, for example rolled onto a transport roller and, when being pulled onto a roller, is drawn on the outer circumference in a helical or helix-like manner.
  • the sawtooth wire has a tooth root with a bearing edge that extends along the length of the sawtooth wire. This support edge serves as a subsequent support or contact section with the roller onto which the sawtooth wire is to be drawn.
  • the sawtooth wire has a row of teeth, which is formed on a tooth side of the tooth base that faces away from the contact edge and is opposite. If the sawtooth wire is stretched out, i.e. neither rolled up on a transport roller nor mounted on a roller, it ideally runs along a straight line. In this state, the row of teeth extends in the longitudinal extension of the sawtooth wire and includes individual teeth. The teeth are arranged one behind the other in a row in the longitudinal extent of the sawtooth wire in such a way that they protrude from the tooth side essentially perpendicularly to the longitudinal extent of the sawtooth wire.
  • Each tooth has a tooth tip that points along the length of the sawtooth wire and in a same direction as the tooth tips of the other teeth in the row of teeth. This direction can be parallel to the tooth side or form an acute angle with it, ie point away from the tooth side.
  • each tooth has a tooth breast. Starting from the associated tooth tip of the respective tooth, this is designed in such a way that in a first section it extends at an acute angle on the tooth side towards an associated tooth back of the tooth. The first section transitions into a concave second section adjoining its end remote from the tooth tip. Its end remote from the first section points at an acute angle to the tooth side in the direction of the tooth side and away from the associated tooth back.
  • the second section merges into a third section which adjoins its end remote from the first section and which extends further towards the tooth side and also away from the associated tooth back.
  • the third section merges into a concave fourth section, which adjoins its end remote from the second section and whose end remote from the third section points along the longitudinal extent of the sawtooth wire and away from the associated tooth back.
  • the fourth section now transitions into a tooth back of the tooth arranged next in the row of teeth, adjoining its end remote from the third section, ie it borders on this tooth back.
  • the length the tangent from the reversal point to the tooth side is greater than or equal to half a distance, seen along the tangent (transverse to the longitudinal extent of the sawtooth wire), between the associated tooth tip and the tooth side.
  • the tangent length therefore defines the distance between the reversal point and the tooth side. This results in a tooth tip that is relatively low in relation to the height dimension of the entire tooth. This means that when the sawtooth wire is being pulled on, i.e. when it is pulled onto an associated roller, fiber material that is to be processed (e.g. carded) by means of the teeth can no longer easily get into the spaces between the teeth and remain there.
  • the fact that the fourth, concave section merges directly into the tooth back of the next tooth means that this transition point is very small.
  • the effect of this is that hardly any fibers can collect there but, due to the rotational speed of the associated roller, are guided almost immediately in the direction of the second section, which is positioned quite high in relation to the roller surface.
  • more fiber material is supplied for further processing (e.g. in the form of stretching) than is the case with conventional sawtooth wires. Waste is reduced and with it the number of rejects; the efficiency of a spinning preparation machine equipped with such a sawtooth wire is improved. As a result, the fibers are guided higher in relation to the roll surface.
  • the ratio between the length of the second tangent, i.e. the distance from the reversal point to the tooth side, to the aforementioned distance between the tooth tip and the tooth side is 4:5 tooth tip be conveyed when the respective tooth is guided past fiber material with the tooth tip first.
  • the second section can correspond to a section of a peripheral line of an ellipse. This creates an edge-free and therefore continuous tooth face in this area. The risk of fibers jamming in this area of the tooth face is averted or at least greatly reduced.
  • the ellipse is a circle with a predetermined radius. This is a geometric shape that is particularly easy to produce.
  • the radius is preferably smaller than a difference between the length of the second tangent and the aforementioned distance between the tooth tip and the tooth side. This allows the reversal point to be positioned very close to the associated tooth tip, further helping to reduce waste.
  • the radius is preferably about 0.07 mm. This has proven to be a very favorable value in terms of fiber intake at the tooth face.
  • the wording “approximately” relates to production-related tolerances in relation to the respective reference variable, here the radius.
  • the aforementioned distance between the tip of the tooth and the side of the tooth is preferably about 0.5 mm for all sawtooth wires specified above. This is a particularly suitable value in order to be able to process enough fibers.
  • the ratio between the peak height i.e. the distance between the tooth side and the tooth tip in a direction transverse to the tooth side or to the longitudinal extent of the sawtooth wire, and a tooth spacing along the longitudinal extent of the sawtooth wire from the tooth tip of a tooth to the tooth tip of the immediately adjacent tooth teeth of the row of teeth 5:17.
  • this tooth spacing may be less than about 2 mm, preferably about 1.7 mm or 1.5 mm. These lengths have proven to be particularly favorable with regard to the fibers to be processed, in particular with regard to their length.
  • the second tangent and a first tangent applied to the first section at the location of the associated tooth tip preferably enclose a predetermined acute angle in all of the aforementioned sawtooth wires.
  • this angle is essentially at least 30° and at most 55°. This angular range allows very efficient fiber treatment.
  • the tooth back of a tooth preferably comprises a fifth and a sixth section.
  • the fifth section follows the fourth section of the tooth of the row of teeth arranged in front of it and extends away from this fourth section.
  • the sixth section in turn now closes to the fifth section at its end remote from the fourth section and extends towards the tooth tip of the associated tooth.
  • the fifth and sixth sections enclose acute angles on the tooth side that are different from one another. i.e. Both sections have different slopes in relation to the tooth side in the direction of the tooth tip and thus enable a kind of intermediate reception, but at least a guidance of fibers in the direction of the second section of the tooth face that abuts the tooth back directly in the row of teeth.
  • the largest angle between the fifth section and the tooth side is preferably smaller than the largest angle between the sixth section and the tooth side.
  • the picked-up fibers are thus released much more slowly or not at all in the direction of the tooth side over the sixth section than the fifth section allows. For example, fibers can be brought into the processing process better due to centrifugal force than would be possible with a section with only one pitch.
  • the tooth back can further comprise a seventh section, which adjoins the sixth section at its end remote from the fifth section.
  • the seventh section encloses a largest acute angle with the tooth side, which is larger than the largest angle between the sixth section and the tooth side. This creates a kind of step in the area of the sixth section, even if it does not necessarily run parallel to the tooth side and is therefore quasi-horizontal.
  • the tooth tip of the associated tooth thus protrudes further from the tooth side than the sixth section and can thus be optimized for the extraction of fibers, while the seventh section and the second section are each attached to the sixth Section adjoining tooth face can be optimized for guiding and discharging unwanted fibers.
  • the tooth back preferably comprises an eighth section, which adjoins the seventh section at its end remote from the sixth section.
  • This eighth section encloses a largest acute angle with the tooth side, which is smaller than the largest angle between the seventh section and the tooth side. This creates a kind of hump between the tooth tip and the seventh section, which has a similar effect to the fibers as the sixth section.
  • the transition area between at least two directly adjacent sections and/or the transition area between the respective fourth section and the adjoining tooth back can be continuous. i.e. In the extreme case, there are no discontinuous transitions between two immediately adjacent tooth tips that would allow or promote the adhesion of fibers and thus negatively influence the effect of the sawtooth wire.
  • FIG. 12 shows a saw-tooth wire 1 according to a first embodiment of the invention in side view when the saw-tooth wire 1 is stretched out.
  • Figure 1b shows the sawtooth wire 1 in section along a line AA in Figure 1a.
  • Figure 1c again shows the in Figure 1a The area surrounded by a square is enlarged in detail.
  • the sawtooth wire 1 has one in Figure 1a and Figure 1b lower area a tooth base 2, on the upper side of which a row of teeth is formed.
  • the row of teeth essentially consists of several teeth arranged in a row one behind the other 3.
  • the tooth base 2 has an underside that serves as a bearing edge 4 for the roller, not shown, onto which the sawtooth wire 1 is to be mounted.
  • the side of the tooth root 2 facing the teeth 3 forms a tooth side 5.
  • the tooth side 5 is designed in such a way that it transitions from the right-hand edge of the tooth base 2 in the direction of the tooth 3 .
  • the teeth 3 have, in a known manner, a tooth back 10 and a tooth face 20 which meet at one end at a tooth tip 6 of the respective tooth 3 and at the other end in the tooth face 20 of the immediately in front of it arranged tooth 3 or the tooth back 10 of the tooth 3 arranged immediately thereafter.
  • the tooth root 2 is formed from a material that allows the sawtooth wire 1 to be drawn onto an associated roller. For this purpose, it has a predetermined height hF .
  • the back of the tooth 10 of the respective tooth 3 begins, starting from the tooth face 20 of the one in front of it, i.e. in Figure 1a left of it, arranged tooth 3 with a portion 11 which is formed in relation to the tooth side 5 in the direction of tooth tip 6 increasing.
  • the section 11 runs at an acute angle to the tooth side 5 towards the tooth tip 6 .
  • a section 12 of the tooth back 10 connects to this section 11 .
  • the section 12 runs flatter in relation to the tooth side 5 or even parallel to it.
  • section 12 merges into a next section 13 , which is designed to be steeper than section 12 and, for example, flatter than section 11 .
  • section 13 At its end remote from section 12, section 13 in turn opens into what is now the last section 14 of tooth back 10.
  • the end of section 14 remote from section 13 forms, in conjunction with an adjoining section 21 of tooth face 20, tooth tip 6.
  • the section 21 extends away from the tooth tip 6 towards the tooth side 5 and the tooth back 10 of the same tooth 3.
  • the essentially straight section 21 transitions at its end remote from the tooth tip 6 into a section 22 which, in the example shown, follows the circumference of a circle with a predetermined radius.
  • the radius is approximately 0.07 mm, for example.
  • the transition between sections 21 and 22 is preferably continuous designed. This has the advantage that fibers located there can move past the tooth face 20 without the risk of jamming.
  • section 22 merges into a subsequent section 23.
  • this is preferably straight, similar to section 21 . It extends to the side of the tooth 5 and to the back of the tooth 10 of the following tooth 3 . This results in a sloping area in relation to the tooth base 2 .
  • the section 23 transitions at its end remote from the section 22 into a concave section 24 which, at its end remote from the section 23, adjoins the tooth back 10 of the immediately following tooth 3.
  • the section 24 has a minimal distance to the tooth side 5 in relation to the rest of the tooth 3, which is sufficient to lay the sawtooth wire 1 around a roller. To do this, it is necessary to bend the sawtooth wire 1 in such a way that the in figure 1 straight bearing edge 4 rests firmly on the outer circumference of the roller at all points. This minimum distance is preferably 0.1 mm.
  • Section 22 has at its in figure 1 at the point furthest to the left, perpendicular to the tooth side 5, has a distance or a height hu, which is 0.5 mm, for example. In relation to the tooth side 5, this point is therefore significantly higher than half a distance or a height hz of the tooth tip 6 to the tooth side 5. This distance thus corresponds to the length of a tangent (vertical dot-dash line) that can be applied at this point and perpendicular to the tooth side 5 runs.
  • a tooth tip distance az between the tooth tips 6 of two immediately consecutive teeth, ie the pitch, is shown in FIG Example less than about 2 mm, preferably about 1.7 mm or 1.5 mm with a tolerance of +0.06 mm to -0.03 mm.
  • a length I R of the respective tooth back 10 along the longitudinal extent of the sawtooth wire 1 when stretched out, ie along the tooth side 5, is, for example, more than half of the aforementioned tooth tip spacing az.
  • a tangent applied to the section 21 in the region of the tooth tip 6 encloses a predetermined angle ⁇ with a line which is perpendicular to the tooth side 5 and intersects the tooth tip 6 .
  • the angle ⁇ is 55° and is therefore just as large as a corresponding angle between this tangent and the aforementioned tangent applied to the reversal point in section 22 .
  • the root of the tooth 2 in Figure 1b can of course also point to the left, so that the sawtooth wire 1 is mirrored along a vertical line in this figure.
  • figure 2 12 shows a sawtooth wire 1 according to a second embodiment of the invention.
  • the tooth back 10 has only three sections 11-13 here instead of four. Sections 11-13 are similar to sections 11-13 of the first embodiment, section 14 is missing. The result is that a tangent applied to section 13 and intersecting the tooth tip 6 encloses a larger acute angle ⁇ with the tooth side 5 than with the first embodiment of the invention.
  • the angle ⁇ is the same as the first embodiment, for example.
  • figure 3 12 shows a sawtooth wire 1 according to a third embodiment of the invention.
  • the section 11 is a concave section which, at its end remote from the previous tooth 3, merges into a section 12 which is connected by means of a rising plane with respect to the tooth side 5 is formed.
  • the adjoining section 13, which extends to the tooth tip 6 is preferably designed like the section 14 of the first embodiment of the invention. i.e. here the section 12 present in the first embodiment is missing.
  • the section 21 runs steeper than in the second embodiment. As a result, the angle ⁇ is comparatively smaller and is 40° in the example shown.
  • figure 4 12 shows a sawtooth wire 1 according to a fourth embodiment of the invention.
  • the section 13 is shorter.
  • figure 5 12 shows a sawtooth wire 1 according to a fifth embodiment of the invention.
  • section 13 is made substantially longer than in the previous embodiments. This leads to a longer dwelling of the respective fiber in the upper area of the sawtooth wire 1 and thus reduces the risk of fibers being able to accumulate in the area of the section 11 .
  • section 24 is made shorter than in the previous embodiments.
  • the invention is not limited to the prescribed embodiments.
  • tooth face 20 and tooth back 10 described above, or their sections 11-14; 21 - 24, can be combined with each other or interchanged in any way.
  • the second and the fifth embodiment can be combined with one another in such a way that the tooth backs 10 are terraced.
  • the aforementioned radius at section 22 can also assume a different value.
  • the section 22 can also correspond to a partial circumference line of a non-circular ellipse.
  • the invention creates a sawtooth wire 1 that is particularly suitable for drums and effectively prevents fibers from accumulating in the lower area, ie in the area between tooth face 20 and tooth back 10 of two consecutive teeth 3 . i.e. the fibers are kept in bulk farther away from the tooth side 5 and closer to the respective tooth tip 6.
  • This has a particularly favorable effect that the fibers of the Sawtooth wire 1 can be removed from a corresponding roll. In particular during carding, the fibers can thus be better fed to the receiving roller, which improves the efficiency of the spinning preparation machine provided with the sawtooth wire 1 .
  • a further advantage is that the sawtooth wire according to the invention makes it easier for the fibers to be fed to other elements which interact with the sawtooth wire, such as covers and strips.
