Definitions

  • a sliver trumpet having an exit bore and an inner wall continuously converging into and upon said bore. Positioned on the inner walls are a plurality of vent holes extending through the walls.
  • FIG. 1 is a side elevation of a trumpet, according to the present invention, in operation
  • FIG. 2 is an enlarged side elevation, partly in section, of the trumpet shon in FIG. 1;
  • HG. 3 is an enlarged isometric view, partly in section, of the trumpet shown in FIG. 1;
  • FIG. 4 is a plan view of the trumpet shown in. FIG. 2 along the line 44 thereof.
  • a condensing trumpet which has an entrance 11 and an exit bore 12.
  • vent holes 16 Spaced from the exit bore 12 on the wall 14 are positioned a plurality of vent holes 16 which extend, at substantially right angles to the axis of the trumpet, through the wall 14.
  • the holes 16 are of small diameter relative to the fiber staple length, e.g. A inch, to prevent fibers of substantial length from passing therethrough.
  • the holes 16 are preferably spaced from the exit bore 12 by a distance approximately in the range of from 75% of the fiber staple length of the fibers with which the trumpet is to be used thereby positioning the holes 16 along that portion of the trumpet in which the air is expelled from the sliver passing therethrough in order that a minimal amount of turbulence is created therewithin.
  • the vent holes 16 are preferably disposed symmetrically about the inner wall 14, FIG. 4.
  • FIG. 1 a sliver 24 to be condensed is fed through the trumpet 10. As the sliver 24 approaches the exit bore 12 and is restricted by the inner wall 14 and the bore 12, the air entrained in the sliver 24 is forced out and escapes through the vent holes 16. The sliver 24 then passes through the exit bore 12 and is processed as between the rolls 20, 22 in FIG. 1.
  • a vented condensing trumpet for use in textile machinery comprising:
  • a vented condensing trumpet for use in textile machinery comprising:
  • a plurality of symmetrically disposed openings spaced from said exit bore a distance in the range of 25-75% of the staple length of the fibers in a sliver passing through said member, thereby to permit entrained air to escape smoothly from said sliver within said trumpet and exit bore.
