Definitions

  • the present invention relates generally to cards with multiple carding units, particularly for preparing non-woven textile webs and slivers for semi-worsted yarns.
  • the invention concerns a roller card of the type including at least one first stage, at least one second stage, and a third stage, in which:
  • Roller cards of this type are generally provided with a single first stage and a single second stage which form, with the third stage, a card with two carding units of which the first serves to supply and rough the material, and the second to improve the opening, distribute the fibre, and to form and discharge the web.
  • the object of the present invention is to provide a card of the type specified above, which is able further to improve the productivity of the machine and the quality of the web or sliver produced by the machine.
  • the intermediate combing means include at least two intermediate combing rolls for forming respective webs
  • the conveyor means include at least two conveyor rollers each cooperating with a respective intermediate combing roll.
  • the cylinder of the or each first stage is covered by a cloth with a low angular value and with pointed ends facing in the direction of rotation, which corresponds to that of the advance of the material.
  • the intermediate combers are covered by cloths with a high angular value and with pointed ends facing in the opposite direction from that of rotation.
  • the intermediate combers may be covered by cloths with different angles and densities, and may have different peripheral velocities.
  • the conveyor rollers have cloths with pointed, ends facing in the opposite direction from that of the advance of the material and strip the two combers by drawing (peripheral velocity greater than that of the combers) or by "condensation" (peripheral velocity lower than that of the combers), transferring the web just formed to the cylinder of the final stage without altering its characteristics.
  • the embodiment illustrated in the drawings relates to a roller card with two carding units, particularly for producing non-woven textile webs and slivers for semi-worsted yarns. It should be noted, however, that what is described below can also be applied to cards having a greater number of carding units.
  • the card illustrated is composed of a first stage generally indicated I, a second stage generally indicated II, and a third section generally indicated III.
  • Stage I includes an endless-belt feed conveyor A for supplying staple fibres to opening members with rolls B, C, and a first carding unit consisting of a cylinder D and two intermediate combing rolls E 1 , E 2 .
  • the senses of rotation of the rollers B, C, D,E 1 and E 2 are those indicated by arrows in the drawings.
  • the cylinder D is covered by a cloth with a low angular value and pointed ends facing in the direction of rotation, that is, in the direction of advance of the material.
  • the two intermediate combers E 1 , E 2' which replace the single intermediate comber present in conventional cards, are covered, however, by cloths with a high angular value and with pointed ends facing in the opposite direction from that of the rotation.
  • the two intermediate combers E 1 , E 2 may be covered by cloths with angles and densities that are the same or different, and may have the same or different peripheral velocities.
  • Stage II is constituted by two conveyor or doffer rollers F 1 , F 2 each of which cooperates with a respective intermediate comber E 1 , E 2 .
  • the two conveyor rollers F 1 , F 21 which in practice act as transfer members between stage I and stage III, are covered by cloths with pointed ends facing in the direction of rotation indicated by the arrows, and may have a peripheral velocity greater than or less than that of the respective intermediate combers E 1 , E 2 .
  • the stripping action exerted by the conveyor rollers F 1 , F 2 on the respective intermediate combers E 1 , E 2 occurs by a drawing action, while in the second case it is achieved by "condensation".
  • Stage III includes a second carding unit formed by a cylinder G and by two output combers H 1 , H 2 rotatable in the senses indicated by the respective arrows.
  • the two combers Hit H 2 supply respective doffer members Pit P 2 .
  • stages I, II and III form a card with two carding units, in which stage I serves to supply and rough the material and stage III serves to improve the opening, distribute the fibre, and to form and discharge the web or sliver.
  • the function of the two intermediate combers E 1 , E 2 is that of collecting the fibres from the cylinder D on their surfaces to form two webs.
  • the two webs formed in the first stage are conveyed by means of the two conveyor rollers F 1 , F 2 to stage III.
  • the latter is thus supplied with a greater quantity of fibres, achieving greater production and better quality of the web or sliver.
  • the clearing of the cylinder D by the two intermediate combers E 1 , E 2 halves the faults in the feed onto the cylinder G, in that the supplied collections of fibres are separated into two different paths.
  • the greater production obtainable with two (or more) intermediate combing rolls permits the use of finer cloths of greater carding power from stage I, thus allowing a further improvement in the quality of the final product.
  • the card according to the invention allows substantial improvements to be obtained in the final product from both the quantitative and qualitative aspects, in terms of greater homogeneity and strength as well as greater unit weights of the webs.
