Definitions

  • the invention relates to a sawtooth wire for rolls of spinning preparation machines, such as cards, in particular a sawtooth wire for a spool.
  • Such sawtooth wires are usually produced as strand material, possibly rolled up on transport rollers and wound up in a helical or helical manner along an outer circumference of a corresponding roller, for example a spooling roller, for use. Such formed rolls are used for a variety of purposes. There are cleaning rollers designed to separate incoming fiber material from contaminants, such as cotton boll material. Other sawtooth wires, in turn, are designed to loosen and parallelize fibers, as is the case, for example, with drum tambour rollers. In the case of rolls stored in a processing chain, there is a need to remove fiber material from an upstream location and deliver it to a downstream location, and this at the highest possible speed.
  • a sawtooth wire is provided, which is adapted to be wound helically on a roll of a spinning preparation machine along an outer circumference of the roll and substantially transverse to its axis of rotation.
  • the sawge leopard- wire is preferably prepared in a known manner as a strand material, for example, rolled onto a transport roller and mounted on a roll on its outer circumference helical or helical when mounted.
  • the sawtooth wire has a tooth root with a bearing 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 on which the sawtooth wire is to be mounted.
  • the sawtooth wire has a row of teeth which is formed on a side facing away from the support edge and opposite tooth side of the tooth root. If the sawtooth wire is stretched out, ie neither rolled up on a transport roller nor mounted on a roller, it runs ally along a straight line. In this state, the row of teeth extends in the longitudinal extent of the sawtooth wire and includes individual teeth. The teeth are arranged one behind the other in the longitudinal extent of the sawtooth wire in a row such that they protrude from the tooth side substantially perpendicular to the longitudinal extent of the sawtooth wire. Each tooth has a tooth tip pointing along the longitudinal extent of the sawtooth wire and in the same direction as the tooth tips of the other teeth of the tooth row.
  • this direction may be parallel to the tooth side or include with this an acute angle, ie point away from the tooth side.
  • every tooth has a tooth face. This is, starting from the associated tooth tip of the respective tooth, formed so that it extends in a first portion at an acute angle to the tooth side to an associated tooth back of the tooth.
  • the first section merges into a concave second section adjacent to the end of 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 adjoining its end remote from the first section and extending further to the tooth side and also away from the associated tooth back.
  • the third section merges into a concave fourth section adjoining the end remote from the second section, whose end remote from the third section points along the longitudinal extension of the sawtooth wire and away from the associated tooth back.
  • the fourth section now merges into a tooth back, which is located at the end remote from the third section, of the tooth subsequently arranged in the row of teeth, thus adjoining this tooth back. Further, there is a reversal point in the aforesaid second section where a second tangent applied to the second section is perpendicular to the tooth side.
  • the length the tangent from the point of reversal 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 thus defines the distance between the reversal point and the tooth side. This results in a relative to the height dimension of the entire tooth relatively low tooth tip.
  • the ratio between the length of the second tangent, ie the distance between the point of reversal to the tooth side, the aforementioned distance between the tooth tip and tooth side 4 5: This allows more fiber material in the aforementioned third section and can from this in the direction of the second section near the associated Tooth- tip are conveyed when the respective tooth with the tooth tip is guided past fiber material.
  • the second portion may correspond to a portion of a circumferential line of an ellipse in the aforementioned cases. This results in an edgeless and thus continuously extending tooth face in this area. The risk of jamming of fibers in this region of the tooth face is banned or at least greatly reduced.
  • the ellipse is a circle having 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 tooth tip and tooth side. This makes it possible to position the reversal point very close to the associated tooth tip, which helps further reduce the waste.
  • the radius in both cases is preferably about 0.07 mm. This has proven to be a very favorable value in terms of fiber uptake on the tooth face.
  • the term "about” refers in the context of the invention to manufacturing tolerances with respect to the respective reference, here the radius.
  • the aforementioned distance between the tooth tip and the tooth side is preferably about 0.5 mm in the case of all the sawtooth wires specified above. This is a particularly suitable value to be able to process enough fibers.
  • the ratio between tip height that is, the distance between the tooth side and tooth tip in a direction transverse to the tooth side and the longitudinal extension 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 arranged Tooth of the row of teeth 5: 17 amount.
  • This pitch may be less than about 2 mm, preferably about 1, 7 mm or 1.5 mm, with or without respect to the ratio of 5:17. These lengths have proven to be particularly favorable with respect to the fibers to be processed, in particular with respect to their length.
  • the second tangent and a first tangent applied to the first section at the location of the associated tooth tip preferably include a predetermined acute angle in all the aforementioned sawtooth wires.
  • This angle is preferably substantially at least 30 ° and at most 55 °. This angular range allows a very efficient fiber treatment.
  • the tooth back of a tooth preferably includes fifth and sixth portions.
  • the fifth section adjoins the fourth section of the previously arranged tooth of the row of teeth and extends away from this fourth section.
  • the sixth section in turn closes now- more to the fifth portion at its end remote from the fourth portion and extends to the tooth tip of the associated tooth.
  • the fifth and sixth tooth-side sections enclose acute and different largest angles. Ie. Both sections have mutually strong increases in the direction of the tooth tip with respect to the tooth side and thus allow a kind of intermediate receptacle, but at least a guide of fibers in the direction of the second portion of each immediately in the row of teeth abutting the tooth back tooth face.
  • 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 captured fibers are thus allowed to travel much slower or not toward the tooth side over the sixth section than the fifth section allows.
  • fibers can be better brought into the processing process, for example, due to the centrifugal force, as it would be possible with a section with only one slope.
  • the tooth spine may further include a seventh portion that connects to the sixth portion at its end remote from the fifth portion.
  • the seventh section encloses with the tooth side a maximum acute angle which is greater 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 thus almost horizontally.
  • the tooth tip of the associated tooth protrudes farther from the tooth side than the sixth portion and thus can be optimized for the extraction of fibers, while the seventh section and the second section of each of the sixth Section adjacent tooth face for the conduction and discharge of unwanted fibers can be optimized.
  • the tooth back further comprises an eighth portion which adjoins the seventh portion at its end remote from the sixth portion.
  • This eighth section includes with the tooth side a maximum acute angle 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 with respect to the fibers as the sixth section.
  • the transition region between at least two mutually directly adjacent sections and / or the transition region between the respective fourth section and the adjoining tooth back can be designed to be continuous. Ie. in extreme cases, there are no discontinuous transitions between two tooth tips located immediately adjacent to each other, which allow or promote adhesion of fibers and thus adversely affect the effect of the sawtooth wire.
