Definitions

  • the invention relates to a sawtooth wire for rollers of spinning preparation machines, such as cards, in particular a sawtooth wire for a reel.
  • Such sawtooth wires are usually manufactured as strand material, optionally rolled up onto transport rollers and wound up in a helical or spiral manner along the 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 fiber material from impurities, such as cotton boll material. Other sawtooth wires, in turn, are designed to separate and parallelize fibers, as is the case, for example, with tambour rollers on cards. With rollers stored intermediately in a processing chain, there is a need to take fiber material from an upstream location and deliver it to a downstream location, and to do so 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 inter-tooth space) in the row of teeth of the sawtooth wire, has, seen transversely to the longitudinal extension of the sawtooth wire, when stretched out, a distance from a support surface of the sawtooth wire on the roller that is small enough to be able to bend the sawtooth wire in such a way that it can be placed around the associated roller, as described above, and thus pulled onto this roller.
  • fibres tend to accumulate in this transition area and thus cause usable fibre material not to be processed further, for example not to be removed from a removing roller.
  • Sawtooth wires are made of US 2 937 413 A , WO 99/388661 A1 and CN 204 738 066 U known.
  • the object of the invention is to at least reduce this disadvantage. This object is achieved by the subject matter of claim 1. Advantageous further developments of the invention are specified in the subclaims.
  • a sawtooth wire which is designed to be wound onto a roller of a spinning preparation machine along an outer circumference of the roller and essentially transversely to its axis of rotation in a screw-like or spiral manner.
  • the sawtooth wire is preferably produced in a known manner as a strand material, for example rolled onto a transport roller and wound onto the outer circumference of a roller in a screw-like or spiral manner when wound onto the roller.
  • the sawtooth wire has a tooth base with a support edge which extends along the longitudinal extent of the sawtooth wire. This support edge serves as a later support or contact section with the roller onto which the sawtooth wire is to be wound.
  • the sawtooth wire also has a row of teeth which is formed on a tooth side of the tooth base facing away from the support edge and opposite. If the sawtooth wire is stretched out, i.e. neither rolled onto a transport roller nor wound onto a roller, it ideally runs along a straight line. In this state, the row of teeth extends in the longitudinal direction of the sawtooth wire and comprises individual teeth. The teeth are arranged one behind the other in a row in the longitudinal direction of the sawtooth wire in such a way that they protrude from the tooth side essentially perpendicular to the longitudinal direction of the sawtooth wire. Each tooth has a tooth tip that points along the longitudinal direction of the sawtooth wire and in the same direction as the tooth tips of the other teeth in the row of teeth.
  • each tooth has a tooth breast. Starting from the corresponding tooth tip of the respective tooth, this is designed in such a way that it extends in a first section at an acute angle on the tooth side to an associated tooth back of the tooth.
  • the first section merges into a concave second section that adjoins its end remote from the tooth tip. The end of this section furthest from the first section points at an acute angle to the tooth side towards the tooth side and away from the corresponding tooth back.
  • the second section in turn merges into a third section which adjoins its end furthest from the first section and extends further towards the tooth side and also away from the corresponding tooth back.
  • the third section merges into a concave fourth section which adjoins its end furthest from the second section and whose end furthest from the third section points along the longitudinal extent of the sawtooth wire and away from the corresponding tooth back.
  • the fourth section now merges into a tooth back of the tooth arranged next in the row of teeth which adjoins its end furthest from the third section, and thus borders on this tooth back. Furthermore, there is a turning point in the aforementioned second section at which a second tangent applied to the second section runs perpendicular to the tooth side.
  • the length of 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 extension of the sawtooth wire), between the corresponding 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 of the entire tooth. This means that when the sawtooth wire is wound up, i.e. when it is wound onto an associated roller, fiber material that is to be processed using the teeth (for example, carded) can no longer get into the spaces between the teeth so easily 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 amount of waste is reduced and with it the amount 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 roller surface.
  • the ratio between the length of the second tangent, i.e. the distance of the reversal point to the tooth side, and the aforementioned distance between the tooth tip and the tooth side is 4:5.
  • the second section can correspond to a section of the circumference of an ellipse. This creates an edge-free and thus continuous tooth face in this area. The risk of fibers jamming in this area of the tooth face is eliminated or at least greatly reduced.
  • the ellipse is a circle with a predetermined radius. This is a particularly easy-to-produce geometric shape.
  • 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 corresponding tooth tip, which helps to further reduce the waste.
  • the radius is preferably about 0.07 mm. This has proven to be a very favorable value with regard to fiber absorption on the tooth face.
  • the wording "about” refers to manufacturing-related tolerances in relation to the respective reference value, in this case the radius.
  • the aforementioned distance between the tooth tip and tooth side 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 sufficient fibers.
  • the ratio between the tip 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 extension of the sawtooth wire, and a tooth spacing along the longitudinal extension of the sawtooth wire from the tooth tip of a tooth to the tooth tip of the immediately adjacent tooth in the row of teeth can be 5:17. This creates a ratio of the tooth height (height without tooth base) to the distance between two immediately adjacent sawtooth wire teeth that is very favorable for operation.
  • This tooth spacing can be less than about 2 mm, preferably about 1.7 mm or 1.5 mm, with or without maintaining the ratio of 5:17. 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 corresponding tooth tip enclose a predetermined acute angle in all of the aforementioned sawtooth wires.
  • this angle is essentially at least 30° and at most 55°. This angle range allows for very efficient fiber treatment.
  • the tooth back of a tooth preferably comprises a fifth and a sixth section.
  • the fifth section adjoins the fourth section of the tooth in front of it in the row of teeth and extends away from this fourth section.
  • the sixth section in turn adjoins the fifth section at the end remote from the fourth section and extends towards the tip of the associated tooth.
  • the fifth and sixth sections form acute angles with the tooth side and different largest angles to one another. This means that both sections have different inclines towards the tooth tip in relation to the tooth side and thus enable a type of intermediate reception, or at least a guidance of fibers towards the second section of the tooth face which directly adjoins the tooth back 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 collected fibers are thus allowed to pass through the sixth section much more slowly or not at all towards the tooth side than the fifth section allows. This means that fibers can be brought into the processing process better, for example due to centrifugal force, than is possible with a section with only one gradient would be possible.
  • 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 forms a largest acute angle with the tooth side that is larger than the largest angle between the sixth section and the tooth side. This creates a type of step in the area of the sixth section, even if it is not necessarily parallel to the tooth side and is therefore more or less horizontal. This means that the tooth tip of the associated tooth protrudes further from the tooth side than the sixth section and can therefore be optimized for pulling out fibers, while the seventh section and the second section of the tooth face adjacent to the sixth section can be optimized for guiding and removing unwanted fibers.
  • the tooth back also comprises an eighth section, which adjoins the seventh section at the end remote from the sixth section.
  • This eighth section forms a greatest acute angle with the tooth side, which is smaller than the greatest 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 sixth section in terms of the fibers.
  • the transition area between at least two immediately adjacent sections and/or the transition area between the respective fourth section and the adjoining tooth back can be designed to be continuous. This means that in the extreme case, there are no discontinuous transitions between two immediately adjacent tooth tips that could enable or promote the adhesion of fibers and thus negatively influence the effect of the sawtooth wire.
  • Figure 1a shows a sawtooth wire 1 according to a first embodiment of the invention in side view when the sawtooth wire 1 is stretched out.
  • Figure 1b shows the sawtooth wire 1 in section along a line A - A in Figure 1a.
  • Figure 1c again shows the Figure 1a The area surrounded by a square is enlarged in the detail.
  • the sawtooth wire 1 has a 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 3 arranged one behind the other in a row.
  • the tooth base 2 has a bottom side which serves as a support edge 4 for the roller (not shown) onto which the sawtooth wire 1 is to be pulled.
  • the side of the tooth base 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 edge of the tooth base 2 towards tooth 3.
  • the teeth 3 have, in a known manner, a tooth back 10 and a tooth face 20, which at one end meet at a tooth tip 6 of the respective tooth 3 and at the other end merge into the tooth face 20 of the tooth 3 arranged immediately before it or the tooth back 10 of the tooth 3 arranged immediately after it.
  • the tooth base 2 is made of a material that allows the sawtooth wire 1 to be pulled onto an associated roller. For this purpose, it has a predetermined height h F.
  • the tooth back 10 of the respective tooth 3 begins, starting from the tooth face 20 of the previous one, i.e. in Figure 1a left of it, with a section 11 which is designed to rise in relation to the tooth side 5 in the direction of the tooth tip 6.
  • the section 11 runs at an acute angle to the tooth side 5 towards the tooth tip 6.
  • This section 11 is followed by a section 12 of the tooth back 10.
  • the section 12 runs flatter or even parallel to the tooth side 5.
  • the section 12 merges at its end remote from the section 11, here on the right, into a next section 13 which is steeper than the section 12 and, for example, flatter than the section 11.
  • the section 13 in turn flows into a now last section 14 of the tooth back 10 at its end remote from the section 12.
  • the end of the section 14 remote from the section 13 forms, in conjunction with an adjoining section 21 of the tooth face 20, the tooth tip 6.
  • section 22 merges into a subsequent section 23.
  • this is preferably designed to be straight, similar to section 21. It extends to the tooth side 5 and to the tooth back 10 of the subsequent tooth 3. This results in an area that slopes down in relation to the tooth base 2.
  • Section 23 merges at its end remote from section 22 into a concave section 24, which borders the tooth back 10 of the immediately subsequent tooth 3 at its end remote from section 23.
  • Section 24 has a minimal distance from 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 so that the Figure 1 straight support edge 4 rests firmly on the outer circumference of the roller at all points. This minimum distance is preferably 0.1 mm.
  • a tangent applied to the section 21 in the area of the tooth tip 6 encloses a predetermined angle ⁇ with a line perpendicular to the tooth side 5 and intersecting the tooth tip 6.
  • the angle ⁇ is 55° in the example shown 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 tooth base 2 in Figure 1b can of course also point to the left, so that the sawtooth wire 1 in this figure is mirrored along a vertical line.
  • Figure 2 shows a sawtooth wire 1 according to a second embodiment of the invention.
  • the tooth back 10 has only three sections 11 - 13 instead of four.
  • the sections 11 - 13 are designed similarly to the sections 11 - 13 of the first embodiment, section 14 is missing. This results in a tangent applied to section 13 and intersecting the tooth tip 6 forming a larger acute angle ⁇ with the tooth side 5 than in the first embodiment of the invention.
  • the angle ⁇ is, for example, the same as in the first embodiment.
  • Figure 3 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 formed by means of an ascending plane in relation to the tooth side 5.
  • the section 13 which adjoins it and extends to the tooth tip 6 is preferably designed like the section 14 of the first embodiment of the invention. This means that the section 12 present in the first embodiment is missing here.
  • the section 21 is steeper than in the second embodiment. As a result, the angle ⁇ is comparatively smaller and is 40° in the example shown.
  • Figure 5 shows a sawtooth wire 1 according to a fifth embodiment of the invention.
  • section 24 is shorter than in the previous embodiments.
  • the invention is not limited to the prescribed embodiments.
  • the second and fifth embodiments can be combined in such a way that the tooth backs 10 are terraced.
  • the above-mentioned radius for section 22 may also take a different value.
  • the invention creates a sawtooth wire 1 that is particularly suitable for reels and effectively prevents fibers from accumulating in the lower area, i.e. in the area between the tooth face 20 and the tooth back 10 of two immediately consecutive teeth 3.
  • the fibers can be better fed to the removing roller, which improves the efficiency of the spinning preparation machine provided with the sawtooth wire 1.
  • a further advantage is that the fibers can be better fed to other elements that interact with the sawtooth wire, such as covers and strips, due to the sawtooth wire according to the invention.
