Definitions

  • the present invention relates to a process for the preparation of cotton wool balls, where the above-mentioned manufacturing difliculties are avoided, and which has the characteristic feature that separate parts of equal size are separated at regular intervals from a cotton wool fleece and ball-shaped cotton wool pads are prepared by continuously compressing, rotating and turning the mass of cotton wool.
  • the method proposed for carrying out this process has the characteristic feature that a pivotable separating roller follows a feeding device, and is intended to tear separate pieces ofif the loose cotton wool fleece introduced into the apparatus by the feeding device, where, following the separating roller, at least one compressing channel is provided, tapering towards the feeding device, in which an endless conveyor band is guided.
  • the entire apparatus is such that the parts of cotton wool separated from the cotton wool fleece are conveyed by the conveyor hand through the channel, while they continuously rotate and thus are formed into a ball.
  • FIG. 1 is a side view of a device for the preparation of cotton wool balls
  • FIG. 2 is a plan view of a part of FIG. 1.
  • the number '1 denotes a cylinder, provided in a known manner with needles, which feeds the cotton wool fleece 2, consisting of a mass of fibres loosely felted together, to several parallel devices for the preparation of cottol wool balls; one of these devices is shown by way of example in the drawing.
  • a part of cotton wool fleece as indicated at 3 is passed to this device underneath the pressure roller 4 above an endless conveyor band 5, which follows the pressure roller and has an inclined position.
  • the conveyor band 5 is guided over a guide roller 6 and a drive roller 7.
  • a cam disk 8 is fixed on a shaft of the drive roller 7, and the prolongation 9 of a Z-armed lever 11 pivoted on the shaft engages the circumference of the cam disk 8.
  • a separating roller 12 is rotatably supported between this lever 11 and another lever (not shown) parallel with it.
  • the weight of this roller is partly compensated for by a counterweight 13 the position on the right-hand arm of the lever 11 being longitudinally adjustable.
  • the lever 11 is swivelled by a certain distance in the counterclockwise direction; this will move the separating roller 12 toward the conveyor band 5.
  • the cotton wool fleece 3 is now retained a little in front of the separation roller 12, while the part of the cotton wool fleece 3 below the separating roller 12 is gripped by another endless conveyor band 14, which is in a horizontal position.
  • United States Patent G is convenient to arrange the proportions so that the conveyor band 14 has a greater band speed than the conveyor band 5.
  • the conveyor band 14 is provided with rubber strips 15, arranged across the longitudinal direction of the band, and in groups which are offset with respect to each other, and fixed with regular spacing on the conveyor hand.
  • the endless conveyor band 14 is moved by a drive roller 17 and guided over a guide roller 18, which is turned to a saddle-shaped profile.
  • the conveyor band '14 is also arranged in a casing 19, with the exception of the part placed on the drive roller 17.
  • the drive roller 17 is shaped so that a channel 20, steadily tapering towards the right, is formed on the upper side of the conveyor band 14.
  • a similarly shaped channel 21, with its largest cross-section underneath the guide roller 18, is arranged on the lower side of the conveyor band 14.
  • the two channels 20 and 21 are connected together by means of a circular channel 22 taken round the guide roller 18. While the channels 20, 21 have rectangular cross-sections, the channel 22 has a partly rounded cross-section, owing to the shape of the guide roller 18.
  • the cotton wool balls 23 formed in this way now leave the channel 21 at the left-hand end and drop on a conveyor band 25, which is in a direction perpendicular to that of the conveyor band '14; they are being guided by a deflector 24 as they drop on the conveyor band.
  • the conveyor band 25 collects them and removes them laterally away from the apparatus described here.
  • the cotton wool balls prepared according to the process described here have a very good spherical shape. They are also distinguished by the fact that their material is generally uniformly distributed.
  • a compression channel assembly for receiving and balling severed wads of cotton, said compression channel assembly comprising a casing and 2 3 an endless conveyor mounted in said casing for receiving and transferring the said wads of cotton through the casing, the interior walls of said casing, which are disposed adjacent the various surfaces of the conveyor being of such a configuration and the endless conveyor being so mounted in the casing that a tumbling of said wads as well as a gradual compression of said wads in a plurality of difierent planes is effected prior to the time that the wads are ejected from the assembly, said casing being elongated with certain of the walls of the casing being disposed adjacent the surface of the endless conveyor and comprising first and second gradually converging flat planar surfaced channels, the convergence of one planar surfaced channel being directly opposite to that of the other planar surfaced channel and said planar surfaced channels also conver
  • a device as set forth in claim 1 including an arcuate wall unit which has a partially rounded cross-section connecting said first and second converging planar surfaced channels.
