Definitions

  • the present invention relates to the field of the textile industry, and relates to an improvement, which is provided to textile machines commonly referred to as "cardes", and which aims to reduce the fouling phenomenon of a card resulting from the accumulation of fibers in the lateral parts of the main cylinders of the card.
  • a card has a plurality of cylinders including at least one carding cylinder (commonly referred to as a "big drum") which is provided on its periphery with an aggressive lining and on the periphery of which carding members are mounted at the top.
  • the fibers are introduced at the entrance of the card in the form of a fiber mat, and are individualized at the periphery of the carding cylinder (carding action) by the combined actions of the carding members and the trim peripheral of the carding cylinder.
  • carding members are composed of one or more successive carding groups, each carding group being composed of a first roller commonly called “worker” associated with second roller commonly called “stripper” or “sweeper”.
  • the carding members may be in the form of a fixed upper work element (also called “carding plate”) having a plurality of fixed carding points at the periphery of the carding cylinder.
  • the fibers nevertheless have a tendency to escape laterally from the carding cylinder, and to accumulate between the carding cylinder and all the adjacent fixed parts, that is to say mainly the side flanges and the lower fairing.
  • Such an accumulation of fibers is detrimental to the proper functioning of the card and the quality of the fiber web produced. It is therefore necessary to clean the card frequently to remove the clumps of fibers.
  • This problem of accumulation of fibers arises in the same way for other rolls of the card, such as the sail formation rolls, which are mounted downstream of the carding cylinder (rollers, condensers, ...) .
  • the present invention aims at proposing a new technical solution to the problems of accumulation of fibers between a card roll such as in particular a carding cylinder, a communicating cylinder, etc., and the fixed parts adjacent to this card roll, that is to say the side flanges of the cylinder and the fairing of the cylinder.
  • the invention thus for first object a card which comprises at least one rotary cylinder, at least two fixed side plates mounted on either side of the cylinder, and at least one fixed fairing which is mounted near the cylinder, and which covers the cylinder on at least one sector of its periphery.
  • Each side face of the cylinder defines with each side flange and with the fairing, a side chamber which is sealed at the junction between the fairing and the side flange.
  • the card further comprises first means which are external to the chamber and which can feed the lateral chamber with air.
  • each lateral chamber makes it possible to pressurize each lateral chamber, and to transform it into a blowing chamber generating air flows towards the outside of the chamber, which air flows advantageously prevent the penetration into the lateral chamber of fibers. This reduces the risk of clogging of the cylinder due to a build-up of fibers between the lateral ends of the cylinder (movable member) and the fixed parts surrounding the cylinder (flange, fairing).
  • the invention also relates to a method for reducing the accumulation of fibers in the lateral parts of a rotary cylinder of a card, said card further comprising two fixed side plates mounted on either side of said cylinder, and a fixed fairing which is mounted near said cylinder and which covers said cylinder on at least one sector of its periphery.
  • a seal is made between the shroud and each side flange, and air is introduced into the chamber which is formed between the flange, the shroud and the cylinder, so as to maintain said chamber in overpressure.
  • FIG. 1 shows a double output card for the production of nonwovens, and more particularly nonwovens based on synthetic fibers of the polypropylene, polyethylene, and / or natural fibers type. cotton type, and / or viscose type artificial fibers, ...
  • the card of FIG. 1 comprises a cardboard inlet 1 formed in the usual manner of a trough 1a, of a food roll 1b, and of a breaker cylinder 1c.
  • the breaker cylinder 1c feeds a first rotary carding cylinder 2, which is more commonly called a front-end, and which is equipped on its periphery with a carding insert (in the form of points or any other equivalent means) allowing it to resume the fibers of the periphery of the breaker cylinder.
  • a carding insert in the form of points or any other equivalent means
  • Each carding unit 3 cooperates with the front end 2 and has the function of working the fibers taken in the lining of the front end 2 so as to individualize and parallelize them.
  • the carding groups 3 could be replaced by any other equivalent means fulfilling the same function, and for example by carding plates.
  • the card Downstream of the limber 2, the card has a transfer cylinder 4, also commonly called “communicator”, which allows to take all the fibers at the periphery of the front limb 2 and transfer them to a second carding cylinder 5, still commonly called “big drum”.
  • this second carding cylinder 5 is coated with a carding lining and comparable to the first carding cylinder 2 cooperates with carding groups 3.
  • the card Downstream of the second carding cylinder 5, the card has two lower and upper outputs, each card output comprising a doffer cylinder 6, a detaching cylinder 7, and a transport belt 8.

  • This frame 9 is of the welded type and is composed essentially of vertical uprights 9e connected by cross members 9d, the uprights 9e and crosspieces 9d being constituted by rigid metal tubes, preferably steel.
  • FIG. 2 shows the portion of the card at one of the two ends of the carding cylinder 5, the part of the card at the other end of the carding cylinder being identical to that illustrated in this drawing.
  • Figure 5 the second carding cylinder 5 is closed at each of these two ends by a side wall 5a, which preferably comprises a recess central recess 5b.
  • the card also comprises a lateral flange F at each end of the carding cylinder 5.
  • This lateral flange F consists of a circular plate substantially of the same diameter as the carding cylinder 5, and is mounted vis-à-vis and at a short distance from the end wall 5a of the cylinder 5.
  • the cylinder 5 is also provided with a curved fairing 11 which is mounted in close proximity to the surface of the cylinder 5, and which covers the cylinder on a part of the periphery of the cylinder.
  • the face 11 'of the fairing 11 which is oriented towards the cylinder 5 is curved and forms more particularly an arc of a circle of substantially the same radius of curvature as the external face of the cylinder 5.
  • the fairing 11 extends longitudinally over at least the entire length of the carding cylinder 5.
  • the shroud 11 is composed of three separate parts 11a, 11b, 11c and 11d.
  • the parts 11a and 11d of the fairing 11 are housed between the communicating cylinder 4 and the lower doffer cylinder 6, and cover the cylinder 5 at the bottom on a first sector of the periphery of the cylinder; part 11d also serves as a fairing for the communicating cylinder 4;

  • each flange F is provided with a peripheral seal 10, mounted on the edge of the flange in a peripheral groove of the flange.
  • This seal 10 is applied in pressure against the face 11 'of the fairing 11.
  • the seal 10 ensures airtightness between the fairing 11 and the side flange F.
  • Each side flange F thus delimits, with the end side wall 5a of the cylinder 5 and with the shroud 11, a lateral chamber E (FIG. 2), the airtightness of which between the shroud 11 and the flange F is ensured by the seal 10.
  • the invention is not limited to the implementation of a seal 10 carried by the flange F, this seal can be replaced by any equivalent means fulfilling the same function, the essential for the invention being that the junction between the flange F and the fairing 11 is sealed.
  • each side plate F has a through opening 12, for the admission of a flow of air.
  • This intake opening 12 is connected by any appropriate means to the discharge opening of a fan V1 (FIG. 1), so that in operation of this fan, air is continuously introduced into the lateral chamber E passing the lateral flange F.
  • V1 fan V1
  • the lateral chamber E is placed and maintained under overpressure, and air escapes from this lateral chamber E, in the form of airflow which are laterally escaping from the two lateral chambers E and which are shown in FIG. 1 by arrows A.
  • the overpressure of the lateral chambers E at the two ends of the carding cylinder 5 in combination with the sealing formed between each flange F and the shroud 11 prevents the fibers to enter the spaces between firstly the carding cylinder 5 (movable member in operation) and secondly the side flanges F and the shroud 11 (fixed parts).
  • it is thus advantageously avoided a fouling of the card which would be related to an accumulation of fibers between on the one hand the carding cylinder 5 and on the other hand the lateral flanges F and the shroud 11.
  • each lateral chamber E has low speeds in order to avoid creating airflow disturbances, especially on the fibers transported by the carding cylinder.
