Definitions

  • ABSTRACT Clothing for the cylinder of a card particularly for use with wool and synthetic fibers comprises a stave having pins mounted in it at a density greater than ten pins per square centimeter with each pin projecting from the stave by a length of less than 2% mm. The length of taper of each pin is greater than the projecting length so that part of the taper is located within the body of the stave thus leading to improved carding of fine denier material.
  • pins at the density mentioned above i.e., greater than 10 per square cm. and which have a length projecting from the stave of less than 2% mm. and a length of taper greater than I this.
  • this largely pre ever been used in the past, i.e., approximately oneeighth inch (-4 mm.).
  • needlepointed pins made of hardened steel have traditionally 'beenused in the bast fiber industry and the length of 4 inmJhas always been regarded as the smallest possiblepin projection.
  • the length of taper isat least 50 percent'grea'ter than the projecting length.
  • the length of taper isat least 50 percent'grea'ter than the projecting length.
  • the presence of the recess is found to be beneficial and moreover it reduces any risk of the surface of the stave being slightly splintered when the pins are inserted and fitted in position.
  • FIG. 1 is a view to a greatly enlarged scale of part of a stave for use on the cylinder of a card shown partly in section and
  • FIG. 2 is a highly schematic view of a cylinder of a card with staves thereon.
  • Staves are shown formed on a cylinder 10 in FIG. 2 and the body of a stave is shown in FIG. 1 as l and is formed with parallel-sided holes 2 at a spacing somewhat greater than 10 per square cm. Needle-pointed pins 3 are fitted in these holes from the rear and are then hammered into position as shown.
  • the length of the tapered portion 4 of each pin is appreciably greater than the projecting length and in the example shown is approximately double this length. Since the holes are parallel-sided a small recess or pocket 5 is formed round the root of each pin as previously described. In aparticular examplethe total length of each pin is 16 mm., the tapered length is approximately 4 mm., theprojecting length is approximately 2 mm., and the diameter of the cylindrical portions of the pin is 1.0 mm.
  • Staves fitted withpins as just described may-be fitted to the cylinder 10 of a card in the normal way and before being placed in operationthe tips of the pins may be subjected to a very light grinding operation so that they are slightly flattened as shown at 6 and lie accurately on a common cylindrical surface thus leading to the improved results described in my earlier specification.
  • Clothing for the cylinder of a card comprising: a stave'having a plurality of holes therethrough, at least a portion of said holes being cylindrical in crosssection, said portion including an outer portion adjacent the outer'surface of the stave, a plurality of pins mounted one in each of said stave holes, said pins having a cylindrical body with.a generally conically tapered end, said cylindrical body being located essentially in the cylindrical part of its respective stave hole, and at least a portion of the tapered end also being located in its respective stave hole, said tapered portion of the pin in its stave hole and the said outer portion of the stave hole defining therebetween a recess surrounding said tapered pin, the said tapered end projecting outward from the surface of the stave a distance less than 2% mm.
  • a stave according to claim 2 in which said pins project from said stave by approximately 2 mm. and have a total tapered length of approximately 4 mm.
  • each said hole in said stave extends with said cylindrical crosssection for the full thickness of the stave.
  • Clothing for the cylinder of a card comprising: a stave having a plurality of holes therethrough, said holes being parallel sided throughout the thickness of the stave, a plurality of pins mounted one in each of said stave holes, said pins having a parallel sided body conforming to the shape of said parallel sided holes and a tapered end, the base of said tapered end located within its respective stave hole and the tipthereof projecting out of said stave hole a distance less than 2% mm., said stave hole and the portion of the tapered end therein thus defining a small recess around the portion of the tapered end within the stave hole.
  • a stave according to claim 5 the total length ofthe tapered end being at least 50 percent greater than the part thereof which projects out of the stave hole.
  • a cylinder for a card fitted with clothing comprising a plurality of staves, each stave having a plurality of cylindrical holes therethrough, a plurality of pins mounted in said stave holes at a density greater than 10 pins per square cm, each said pin having a cylindrical body within its respective stave hole and a tapered length projecting from the outer surface of said stave for a distance of less than 2 /2 mm.
  • said tapered length of the pin in its stave hole and the said outer portion of the stave hole defining therebetween a recess surrounding said tapered pin and wherein the tips of said pins have been flattened by grinding so as to lie accurately on a common cylindrical surface.
