Definitions

  • Embodiments of the present disclosure relates to a web drafting assembly in a textile fibre processing machine. More particularly, embodiments of the disclosure relates to a web drafting assembly incorporated in the wider carding machine i.e. the carding machine of working width more than lm, preferably 1.5m. BACKGROUND OF THE DISCLOSURE
  • Carding is a mechanical process that opens, removes trash and neps, breaks up flocks and unorganized clumps of fibre and then aligns the individual fibres so that they are more or less parallel with each other. Finally, converts the mixed and fluffed-up form of textile material into a soft, untwisted thin rope of sliver form.
  • the fiber mat fed to the carding machine should be of a high degree of uniformity to ensure consistent opening and carding. This uniformity is achieved using the chute feed system, which aims at feeding a fiber sheet of a uniform packing density and uniform linear density to the carding machine.
  • Fibres that are opened and cleaned by licker-in system are transferred to the main cylinder by stripping action. Fibres stripped by the cylinder from the licker-in are transferred to the carding zone, which is the area between the main cylinder and the flats.
  • a carding action is accomplished when the wire of the two surfaces are inclined in opposite directions and the direction and the rates of motion are such that one surface passes the other, point against point.
  • the flats are wired clothed bars rotating at a very slow speed against the high speed cylinder.
  • Fibres that are coming out of the carding zone form a very thin web.
  • the weight of the web is determined by extent of carding such as flats or cylinder settings, the relative carding speed, and the type of cloth on both cylinder and the flats.
  • the web is extracted from the main cylinder by another cylinder called a doffer.
  • the substantial reduction of the surface speed of the doffer as compared to that of the cylinder results in a condensation effect.
  • the fiber web is stripped from the doffer using a stripper roller. It is then passed through a pair of squeeze or crush rolls before it is finally accumulated widthwise into a fiber strand form. The calender rolls compress the fiber strand to provide better integrity and stable flow of material.
  • the fiber strand or the card sliver proceeds upward over guide pulleys to enter the coiler system.
  • This consists of a trumpet guide and a second pair of calender rolls that delivers the carded sliver through a revolving tube into the card sliver can.
  • the rate of sliver delivery varies from about 40 to 300 meters per minute.
  • the wider carding technology wherein the working width of carding cylinder is about 1 to 2m, preferably 1.5m.
  • the advantage of wider carding machine can be seen by comparing with normal carding machine. For example by comparing 1.5m wide card with the lm wide carding machine, in the 1.5m carding machine the fibre density increases to 1.5 times without affecting the chance of deterioration in output quality at economically higher production rate.
  • the above details indicate how delicate it is to run the machine for handling a thin sheet of individualized fibres called a 'web', which is finally condensed into a sliver.
  • the tasks of the carding machine are opening to individual fibre, elimination of short fibres, impurities and dust, disentangling of neps, fibre blending, orientation of slivers, and sliver formation.
  • the sliver quality of good fibre orientation plays a major crucial role in the textile yarn spinning process.
  • web formation starts in the doffer as the fibres are removed from cylinder. The doffer rotates at a considerably slower surface speed than the cylinder speed.
  • the drafting of the fibres helps in parallelising the hooks created in the carding machine. Fibres in a card web are less consolidated and not aligned. It is known fact about the drafting of the slivers, rovings or strands. That the drafting is the process of elongating a strand of fibres, with the intention of orienting the fibres in the direction of the strand and reducing its linear density. In a roller drafting system, the strand is passed through a series of sets of rollers, each successive set rotating at a surface velocity greater than that of the previous set. During drafting, the fibres must be moved relative to each other as uniformly as possible by overcoming the cohesive friction.
  • Uniformity implies in this context that all fibres are controllably rearranged with a shift relative to each other equal to the degree of draft.
  • Such an apparatus is suitable for drafting slivers, rovings or strands since the sliver, roving or strand is thick enough or is immediately twisted so there is little problem of the fibres lapping around the front rollers. It is known that drafting the fibres in the card web, by a relatively small draft, between a pair of rollers/aprons, separated by a gap called nipping distance, removes the hooks and results in lesser waste in combing process. Such drafting assemblies with various embodiments are disclosed in prior arts US 3119152 and 1029/KOL/2005.
  • the distance between the two nip points formed for drafting the web is not to be more than 50% of the fiber span.
  • the ratio for surface speed for drafting the web must be greater than 1 in order that drafting and increased alignment of the fibre is accomplished.
  • a drafting ratio of 1.5 to 4 is preferable with optimum ratio as 3.
  • FIGS. 1 and 2 are the various embodiments for method of obtaining parallelization of textile fibres in a web coming from a doffer cylinder (1) of a carding machine disclosed in the prior art US31 19152.
  • the pick-off point (6) is defined by a nose bar (7).
  • a nip point (8) is defined by the point of first contact between nip roller (3) or top belt or apron (2') and the bottom drafting belt (2) or apron (2").
  • the nipping distance is defined by the distance between pick-off point (6) and nip point (8).
  • the best nip distance is 30-50% fiber span.
  • the distance between (8) and (8') is termed as gripping zone.
  • the disclosed art explains the drafting of the cotton web for improved fiber orientation and hook removal, using pair of conveyors or aprons (2) to avoid lapping of web and formation of acute angle by the apron (2) surface.
  • the distance between the two nip points formed for drafting the web is not to be more than 50% of the fibre span.
  • the ratio of the surface speed for drafting the web must be greater than 1 in order that drafting and increased alignment of the fibre is accomplished.
  • a drafting ratio of 1.5 to 4 is preferable with optimum ratio as 3.
  • Fig 3 is another known prior art of 1029/KOL/2005A.
  • the aprons (2) close to the nip point are arranged to be wedge shaped, with the arms of the aprons (2) on each side of a nip roller assembly covering towards the nip rollers (3a, 3b) and having an acute angle between them.
  • the diameter of the nip rollers (3a and 3b) being used for drafting is a consideration in conjunction with the optimum nipping distance. If the nip rollers (3a and 3b) are too small, there is a tendency for the fibres to lap or wrap around the nip rollers (3a and 3b). However if the nip rollers (3a and 3b) is made too large, the nip distance becomes too large which is disadvantageous.
  • the apparatus according to this prior art utilize the wedge shaped aprons (2) with the arms of the aprons (2) on each side of a nip rollers (3a and 3b) converging towards the nip rollers (3a and 3b) and having an acute angle between them.
  • the disadvantage again here is the diameter of the nip rollers (3a and 3b) that are so small and practically they are lower than 50% span of a cotton fibre which is about 10- 15mm.
  • the drafting ratio has to be more than 1 i.e. the draft ratio should be between 1.5 and 4.
  • the sliver weight which again for a ring spun yarn, the optimum will be 3-5 g/m to have optimum fibre density in cylinder for a one meter wide card.
  • the fibre density is to be either double the requirement in cylinder or the delivered sliver weight should be at least 50% thinner. This leads to reduction in throughput in card.
  • the existing systems and prior arts have failed to take the aforesaid aspect into account. Further, the prior arts and the existing systems runs the carding process at slower delivery speeds, which may not meet the today's demand on requirement of high production cards. The end results are heavier fibre density in cylinder which is a technological disadvantage or lower throughput in card which is an economical disadvantage.
  • a web drafting assembly of a carding machine comprises: an upper and a lower apron assembly arranged proximal to a doffer cylinder for receiving fiber web from the doffer cylinder.
  • Each of the upper and lower apron assembly comprises, at least one apron, one or more drive roller for driving the aprons, wherein the drive rollers are oriented at predetermined angles inside respective loop of each upper and lower apron assembly, and at least one guide member provided proximal to the doffer cylinder for supporting the aprons, wherein a portion between ends of the guiding members and the doffer cylinder forms the fiber web pick off point.
