Definitions

  • This invention relates to serrated wires or strips for use in carding engines, doffers or the like.
  • Wires or strips of the kind indicated are generally produced from wire having an initially round section, such section being modified by a process of rolling to give a wire, which is finally strip like with a rib running along one side to constitute a base or foundation for the finished strip.
  • the thin portion of the finished strip standing above the rib is stamped to produce the necessary teeth or points which may, thereafter, be hardened.
  • the said rib in the finished wire also serves as a distance piece to space the teeth when the toothed wire is wound around a carding cylinder or doifer or when sections of the wire are secured side by side on a carding fiat.
  • wires of the kind indicated above are wound spirally around carding cylinders and doifers or any other parts of a carding engine or the like as may be required.
  • Such wires were utilized originally, for the carding of cotton, wool and other natural fibres and they obviated the necessity for the regular stripping and grinding which was required with the type of card clothing previously in use.
  • a wire of initially round section is modified by a process of rolling so as to produce a strip like element 10 having a rib 11 along one side to constitute a base or foundation for the finished strip.
  • the form imparted to the wire will be apparent from the end views of the various embodiments shown.
  • the thinner portion of the strip like element standing above the rib is then stamped to produce a plurality of teeth or points 12, thereby to give the finished strip a serrated form.
  • the finished strip element may be finely ground on one or both sides in order to remove any burns which may exist as a result of the stamping operation.
  • the teeth 12 on the finished serrated strip have a height L of .040, the leading edge of each tooth being inclined at an angle a of 5 to the vertical while the second edge is inclined at an angle b of 60 to said leading edge.
  • the strip formed in the manner indicated above is provided with teeth 12 have a height L of .060 and have the leading edge inclined at an angle a of 5 to the vertical while the second edge is inclined at an angle b of 45 to said leading edge.
  • a serrated Wire or strip for use in carding engines, doffers or the like for the final stages of the carding or combing of natural or synthetic fibers; said wire strip comprising a relatively thick base and a thinner upper portion having stamped notches therein to produce a plurality of teeth, each of said teeth having a height from said base to the point of the related tooth not less than .010 and not more than .065 so that said teeth are sufiiciently highto hold the fibresand to'create air currents for aligning the fibersbut sufficiently short as substantially to eliminate the presence of any gapor channel between the rows of teeth when the Wire strip is wound on a carding cylinder, dofier or the like or when sections of the Wire are arranged side by side on a cardingfiat.
