Definitions

  • the present invention relates to the field of textile industry, in particular the so-called "wool” cards working wool and long fibers and has for its object such a card.
  • Such a configuration has the disadvantage of causing shortening of the fibers, which is very detrimental for the finished product, since, in general, to obtain a thread of optimum quality it is necessary to seek to obtain and maintain fibers of maximum length.
  • the speed of the layer of fibers to be treated is reduced before each Morel cylinder, between the food cylinder and the large drum, in such a way that the orientation of the impurities contained in the layer of fibers are modified so that the corresponding Morel cylinder hunter eliminates them.
  • a significant speed reduction at the level of each Morel cylinder is more particularly necessary the fact that a maximum of impurities, such as thistles, straws or other vegetable fibers, must be torn from the tablecloth accumulated on each Morel cylinder during its passage under the corresponding hunter.
  • each Morel cylinder being equipped with only one hunter, the shredding is limited and, in the presence of a material in the feed highly charged with impurities, the outgoing product has an imperfect cleanliness.
  • the present invention aims to overcome these drawbacks.
  • wool comprising at least two Morel cylinders, characterized in that each Morel cylinder is provided with at least two hunters, reducing the speed of the web of fibers between the large drum and the following Morel cylinder being relatively small.
  • the attached drawing represents a part of a so-called woolen card, of which a Morel 1 cylinder is mounted, with interposition of communicating cylinders 2, between two large drums 3.
  • the sheet of fibers brought by the large drum 3 upstream is deflected by means of the first communicating cylinder 2 on the Morel cylinder 1 for its treatment of skinning, another skinning treatment being carried out on at least one second Morel cylinder, not shown.
  • each Morel cylinder 1 is provided with at least two hunters 4 and the reduction in speed of the sheet of fibers between the large drum 3 and the following Morel cylinder 1 is relatively small.
  • This embodiment makes it possible at least to double the purification operations on each Morel 1 cylinder and thus to considerably increase the evacuation of plant impurities.
  • the first hunter 4 of each Morel cylinder 1 advantageously has a limited number of blades, rotates at a relatively low speed and evacuates the large impurities by a lifting effect, the following hunter (s) 4 having a higher number of blades, rotating at a higher speed and eliminating finer impurities, essentially by suction effect, the adjustment of the first hunters 4 and of the others hunters 4 being carried out independently at different distances from the corresponding Morel 1 cylinders.
  • the Morel 1 cylinders equipped with several hunters 4, are arranged at different locations on the card and are either coupled to one another, or driven separately.
  • the grouping of several hunters 4 on the same Morel 1 cylinder makes it possible to obtain an assembly much less bulky than an arrangement of two Morel cylinders in tandem. In addition, it is possible to produce a more compact card construction with greater efficiency of the hunters 4.
  • the increase in hunters 4 in a card allows the number of transfer points to be reduced and, therefore, an increase in the peripheral speed of the Morel 1 cylinders and therefore an increase in the speed ranges of the latter and of the hunters 4.
  • the invention it is possible to produce a card having a significant cleaning power while preserving the fibers of the breakage, the latter being, therefore, of better quality. As a result, the product obtained is a better refined product.
  • the provision of a large number of hunters 4 allows a large distribution of the release of thistles and other impurities and therefore to limit the reduction in the tangential speed of the sheet of fibers with an accumulation on a lesser thickness, so that the processing speed of a sheet is increased, which results in a corresponding increase in the efficiency of the machine.
