Definitions

  • This invention relates to a needle. More particularly it relates to a novel needle particularly useful in the felting and fulling arts. 7
  • a novel needle which has an irregular profile is provided. It will be referred to hereinafter as a rasping-profile needle.
  • a rasping-profile is meant that an elevational view of the needle discloses at least one abrupt, hookless break, i. e., a notch or a protuberance having a substantially smooth surface, in the continuity of its edge.
  • abrupt is meant that the extent of the profile discontinuity along the longitudinal axis of the needle is no more than about five or six times the extent of its discontinuity normal to the said longitudinal axis.
  • tangent includes a line or plane contacting a position on a straight line portion of the discontinuity as well as the common meaning of tangent which includes a straight line or plane in contact with a point or curved surface or a curved line or plane in contact with a straight surface. that as the line or plane follows the contour of the discontinuity to positions tangential to the discontinuity, whether tangential to straight lines or curved surfaces, it will sweep out an arc of no more than about 90 degrees.
  • This needle is useful in the fulling process described in U. S. application, Serial No. 415,196, filed March 10, 1954, in the name of George Leslie Moler. It is also useful in a process for forming a coherent, nonwoven, felt-like product by needling a loose batt of a fibrous mass containing a substantial proportion of retractable synthetic filaments, thereby forcibly orienting some of the retractable filaments into a position substantially perpendicular to the ultimate faces of the product and thereafter retracting the filaments by appropriate treatment with heat, swelling agent or the like as described in U. S. application No. 312,067, filed September 29, 1952, in the name of Herbert G. Lauterbach, and now abandoned.
