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 drawback 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, so 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.
  • a skimmer device comprising three assemblies which slag the wool before sending it to the large drum.
  • This device allows, of course, to properly shell, parallelize, turn and clean the fibers, but the speeds of the different scalers are accelerating from one cylinder to another to reach a maximum on the large drum, so that the rectification of impurities is only carried out imperfectly.
  • the present invention aims to overcome these drawbacks.
  • FIGS 1 to 3 of the accompanying drawings show a so-called "wool” card, equipped with at least three Morel 1 cylinders and the tangential speeds of the food cylinders 2 and the large drum 3 are equal, the reduction in speed of the web of fibers between the large drum 3 and the following Morel cylinder 1 being relatively weak.
  • this card does not have an intermediate comber.
  • the card according to the invention may have the following arrangement: a tray 4 followed by a large drum 3 with four working groups 5, this large drum cooperating, via a food cylinder 2 with a first Morel 1 cylinder comprising a hunter 6 and followed, with the interposition of another food cylinder 2 of a second Morel cylinder 1.
  • Morel cylinder 1 Following this Morel cylinder 1 is provided a second large drum 3 provided with three working groups 5, this large drum 3 being again connected to a Morel cylinder 1 with hunter 6 by means of another food cylinder 2, the latter Morel cylinder 1 itself being connected via a food cylinder 2 to a last large drum 3 provided with five working groups 5.
  • the sheet of fibers coming from the tank 4 is brought by the large drum 3 and the food cylinder 2, at constant speed, to the first Morel cylinder 1 whose tangential speed is less than that of said food cylinder 2, so that the ply is braked and tends to accumulate the fibers over a greater thickness and, therefore, to promote a recovery of impurities allowing their uprooting by the hunter 6.
  • the ply can then be transmitted at constant speed to the second Morel 1 cylinder for a second operation of removal of impurities, known as dehardening.
  • the ply taken up by the next food cylinder 2, is accelerated and therefore stretched to be worked on the following large drum 3 before undergoing a further deceleration for treatment on the third Morel cylinder 1
  • the sheet is again accelerated to undergo its final stretching.
  • FIG. 2 of the accompanying drawings shows an alternative embodiment of the invention, in which the arrangement of Morel cylinders 1 with respect to the large drum 3 provided with three working groups 5 is reversed.
  • FIG. 3 represents another variant embodiment of the invention using four Morel 1 cylinders arranged in tandem between the first large drum 3 and the last large drum 3.
  • the sheet of fibers can be worked at a higher speed because the shredding is divided into four operations corresponding to the four Morel cylinders.
  • the invention it is possible to produce a card not requiring an intermediate comber and having a significant cleaning power while preserving the fibers from breakage, the latter being, therefore, of better quality. As a result, the product obtained is a better refined product.
  • the provision of a number of Morel cylinders at least equal to three allows a large distribution of the release of thistles and other impurities and therefore limits the reduction of the tangential speed of the fiber web with an accumulation on a lesser thickness, so that the processing speed of a web is increased, which results in a corresponding increase in the efficiency of the machine.

Claims (2)

  1. Krempel, die mit wenigstens drei Morelzylindern (1) versehen ist und keinen Zwischenabnehmer aufweist, dadurch gekennzeichnet, dass die Tangentialgeschwindigkeiten der Speisezylinder (2) und des grossen Tambours (3) gleich sind, wobei die Geschwindigkeitsverminderung des Faservlieses zwischen dem grossen Tambour (3) und dem folgenden Morelzylinder (1) relativ gering ist, so dass das Vlies gebremst wird und die Tendenz hat, die Fasern zu einer stärkeren Dicke anzusammeln und damit eine Ausrichtung der Verunreinigungen zu begünstigen, was ihr Losreissen durch die Chasseur-Walze (6) erlaubt.
  2. Krempel nach Anspruch 1, dadurch gekennzeichnet, dass die Morelzylinder (1) als übereinanderliegendes Paar zwischen zwei grossen Tambouren (3) angeordnet sind.
