Definitions

  • lickerin devices for carding machines have comprised a rotating cylinder provided with a toothed clothing and arranged to carry a web of fibers from a feed roll to a main carding cylinder or swift past a cleaning knife which scrapes the outer surface of the web to remove relatively large impurities therefrom.
  • a screen is mounted adjacent to the surface of the lickerin to prevent the fibers from being thrown off the clothing teeth by centrifugal force.
  • Another object of the invention is to provide a lickerin arrangement of the above character especially adapted to produce increased combing and cleaning action.
  • a further object of the invention is to provide a lickerin arrangement capable of operating with improved efliciency and at a greater capacity than conventional lickerin devices.
  • a lickerin arrangement comprising a first cylinder rotatable adjacent to the feeding device and the main carding cylinder, a housing forming a chamber in conjunction with the surface of the first cylinder between the feeding device and the main cylinder, and a second cylinder rotatably supported within the housing to collect fibers therein and carry them back to the first cylinder surface.
  • the lickerin housing also includes a deflector adjacent to the first cylinder to deflect fibers away from its surface and a feed plate adajacent to the second cylinder to assist in reforming the fibers into a lap on the second cylinder surface.
  • the arrangement includes a first cleaning knife between the feeding device and the housing and a second cleaning knife between the housing and the main card cylinder to scrape impurities from the surface of the web carried by the first cylinder, both in its original condition and after it has been reformed.
  • the second cylinder in its preferred form, has a perforated periphery and is provided with internal suction to assist in collecting the fibers within the housing while, if desired, a blowing device may be mounted within the housing to direct a stream of air toward the second cylinder to carry fibers toward it.
  • FIG. 1 is a fragmentary view in longitudinal vertical section through a portion of a carding machine illustrating a representative lickerin arranged according to the invention
  • FIG. 2 is a sectional view similar to that of FIG. 1 showing a modified form of lickerin according to the invention
  • FIG. 3A is a side view of the embodiment shown in FIG. 2 illustrating the suction and blowing apparatus.
  • FIG. 3B is an end view of the apparatus shown in FIG. 3A.
  • a lap 1 of fibers to be carded is carried from a supply la to a main carding drum or swift 1b by a rotating feed roll 2 moving adjacent to a feed plate 3 and by a rotating lickerin cylinder 4 provided with a toothed clothing 4a which moves adjacent to the feed roll and to the surface of the swift.
  • a cleaning knife 5 is mounted adjacent to the clothing 4a of the lickerin cylinder so as to scrape the outer surface of the web of fibers carried thereby and remove relatively large impurities 6.
  • the lickerin arrangement also includes a second cylinder 7, similar to the feed roll 2, rotatably supported adjacent to a second feed plate 8, a housing 9 being arranged in conjunction with the feed plate 8 and the lickerin cylinder 4 to form a chamber enclosing the second cylinder 7.
  • another cleaning knife 10 is mounted intermediate the second feed plate 8 and the swift to scrape further impurities from a reconstituted fiber web carried between those two members by the clothing 4a, while a screen 11 of the usual type is disposed adjacent to the clothing 4a between the knife 10 and the swift.
  • a deflector 12 is mounted within the housing.
  • the secondary cylinder 7 has a perforated outer surface and the interior of this cylinder is connected to a suction device so that the chamber formed by the housing 9 is maintained at a reduced pressure and fibers are drawn away from the clothing M by the current of air passing therefrom into the chamber. Furthermore, the internal suction draws the fibers within the chamber toward the cylinder 7 as an aid in reconstituting the fiber web.
  • the lap 1 of fibers is transported from tte supply In across the feed plate 3 to the lickerin clothing 4a by rotation of the feed roll 2 in the direction of the arrow.
  • impurities 6 have been removed by the scraping knife 5 from the outer surface of the Web carried at this point by the lickerin clothing
  • a substantial proportion of the fibers is withdrawn from the clothing and scattered into the chamber formed by the housing 9 by centrifugal force and by the reduced pressure in the chamber.
  • this proportion can be varied, if desired, by adjusting the rotational speed of this cylinder.
  • the second feed .plate 8 is substantially isolated by these elements, there is no flow of air from this portion into the cylinder 7 which would tend to hold the reconstituted web on the surface of the cylinder 7 and, therefore, the web can be withdrawn easily by the clothing of the cylinder 4 as it moves adjacent to the feed plate 8.
  • an internal baffle may obviously be mounted inside the cylinder 7 adjacent to this region in arrangements which do not provide isolation of the region in the manner shown in FIG. 1.
  • FIGS. 2, 3A and 3B the embodiment of the invention shown in FIGS. 2, 3A and 3B is adapted to avoid this difficulty and to assure a uniform flow of fibers.
  • an air blowing outlet 13 connected to a source of air under pressure is mounted within the housing 9 and formed within openings 14 which are disposed .to direct a stream of air across the bottom surface of the chamber toward the secondary cylinder 7 and, if desired, the direction and intensity of the air from the outlet openings may be adjustable.
  • the embodiment shown in FIG. 2 is identical in structure and operation to that of FIG. 1.
  • the air supplyin system comprises a motor 15 driving a fan 16 within a housing 17, a filter screen 18 being positioned so as to intercept all the air flowing toward the fan.
  • Dampers 19 control the flow of air from the fan through two ducts 20 to the outlet device 13, while two further ducts 21 withdraw air from the interior of the cylinder 7 and carry it back to the housing 17.
  • the second cylinder 7 is driven from the feed roll 2 by a chain 22, as illustrated in FIG. 3B.
  • the present invention provides a new and improved lickerin arrangement which is not only capable of processing larger quantifies of fiber material and operating at higher speeds and with greater cleaning and combing efficiency than conventional devices, but also is adapted for use with any conventional carding machine by merely substituting it for a portion of the usual screen mounted below the lickerin cylinder.
  • a lickerin arrangement comprising a first rotatable cylinder having an outer surface adapted to carry a web of fibers from a first location adjacent to its periphery to a second and recombine them into a lap, and feed plate means adjacent to the second cylinder to direct the reconstituted lap back to the periphery of the first cylinder, and means within the housing means for removing additional fibers from the first rotatable cylinder.
  • a lickerin arrangement comprising a first rotatable cylinder having an outer surface adapted to carry a web of fibers from a first location adjacent to its periphery to a second location adjacent to its periphery, housing means enclosing a portion of the periphery of the first cylinder between the first and second locations forming a chamber to receive fibers from the peripheral surface of the first cylinder, a second rotatable cylinder mounted within the housing means to collect the fibers within the chamber and recombine them into a lap and feed plate means adjacent to the second cylinder to direct the reconstituted lap back to the periphery of the first cylinder, the second cylinder being disposed with its surface closer to the feed plate means than to the housing means, a first cleaning knife mounted adjacent to the periphery of the first cylinder between the first location and the chamber and a second cleaning knife mounted adjacent to the periphery of the first cylinder between the chamber and the second location.
