Definitions

  • This invention relates to textile carding machines and to a method of operating such machines. More particularly, but not exclusively, the invention is applicable to cotton type carding machines, that is to say, a machine having a single card clothed cylinder over which the material is passed, there being slow moving card clothed flats or rollers or even stationary plates cooperating with the cylinder to perform the carding action.
  • the cotton type carding machines in general use are capable of producing only a limited quantity of carded web per hour.
  • this quantity can be varied within limits according to the quality of the cotton or synthetic fibres being carded, and the standard required of the finished sliver delivered from the machine.
  • a rate of production of 5 pounds (weight) per hour would be quite normal for a good quality finished product, it is possible to achieve up to 20 pounds per hour production, if a substantial deterioration in quality is acceptable.
  • the present invention provides a means whereby a carding machine can be operated to give a high rate of output.
  • a method of carding textile fibres comprises passing the fibrous material through a carding machine, the cylinder and doffer of which are driven at high surface speed (as hereinafter defined), passing the thin web of carded fibres leaving the dolfer through the nip of a pair of ironing rollers, and subjecting the uncondensed web to a drafting action.
  • the normal speed of the cylinder in a conventional carding machine is around 165 to 185 revolutions per minute, assuming the usual cylinder diameter of approximately 50 inches.
  • the normal speed of the doffer in such a conventional carding machine is within the range of 7 to 16 revolutions per minute, assuming the usual dotfer diameter of approximately 27 inches.
  • the ironing rollers employed must operate on the full width of the carded web, and they may be of any known construction, but it is preferred that they should be hard, smooth surfaced rollers. In order to produce the drafting effect between the ironing rollers and the calender rollers, the latter must be rotated at a higher surface speed than the ironing rollers, and whilst the degree. of drafting can be varied somewhat, a draft of 10 percent has been found satisfactory, but a draft of 30 percent is to be preferred. It must be emphasised that the combi nation of the ironing roller treatment and the drafting action is essential to provide the control required for the web coming oh? the dofier. It is preferred to apply such pressure to the ironing rollers as will produce an ironing or smoothing effect on the individual fibres as this improves the appearance of the finished yarns.
  • FIG. 1 is a diagrammatic representation of a cotton type carding machine.
  • the machine used is an ordinary revolving flat cotton type carding machine having the usual cylinder 10, flats 12, takerin roller 14, and dolfer 16. All of these are card clothed, and it may be mentioned here, that it is preferred to use metallic wire or saw tooth card clothing on the cylinder and/or doffer. It is also convenient to use a worker roller 18 in the are between the cylinder and the takerin roller.
  • the cylinder 10 is 50 inches diameter and the doifer 16 is 27 inches diameter.
  • a high speed fiy comb 20 is provided for removing the carded web from the doffer, but it will be understood that any method of stripping the dolfer could be employed.
  • a pair of smooth surfaced rollers 22 and 24 adapted to press the web across its full width.
  • These ironing rollers are geared to the machine drive (not shown) so that their speed of rotation is related to the dolfer speed, and the gearing is preferably such that the surface speed of the pressure rollers is greater than that of the dotfer.
  • the usual condenser trumpet 26 and calender rollers 28 and 30 are provided, and it is essential that the gearing between the ironing rollers and the machine drive is such that the calender rollers rotate at a surface speed which is greater than that of the ironing rollers to produce the drafting effect, and in this particular example they are arranged to have a surface speed 30 percent greater than that of the ironing rollers.
  • scraper blades may be pressed into engagement with the surface of each roller, either by springs or by weighted levers or both.
  • any other convenient means may be provided for this purpose.
  • the ironing rollers may be cylindrical, but it may be desirable to make them slightly barrel shaped to compensate for deflection when pressed tightly together and so ensure contact along the entire lengths of the rollers.
  • Another way of ensuring even distribution of pressure is to arrange the rollers with their axes slightly inclined to one another or crossed that is, by swinging one roller about an axis whichis radial to both rollers and passes through the mid point of both roller axes, such an arrangement being described in the specification of British Patent'No. 697,106.
  • the cylinder is rotated at a speed of 320 revolutions per minute, and the doffer at a speed of 26 revolutions per minute.
  • the speed of the flats and that of the takerin roller is not critical, but is preferably greater than usual.
  • a method of carding textile fibres comprising passing the fibrous material through a carding machine, the cylinder and doffer of which are driven at high surface speeds which are respectively up to about twice and more and from 3 to 7 times the speeds normally employed for any particular fibre in known conventional carding machines, removing the material from the dofier as a thin carded web, passing the thin web of carded fibres leaving the doifer through the nip of a pair of ironing rollers and subjecting the uncondensed web leaving the ironing rollers to a drafting action sufiicient to cause relative longitudinal fibre movement in the web.
