Definitions

  • This invention relates to improvements in hosiery seaming machinery and more especially to a machine for seaming ladies hosiery at high speed.
  • the hosiery to be seamed has been :fed through the seaming machine by means of a pair of driven contra-rotation feeding cups disposed adjacent each other, on a horizontal plane, :and these feeding cups have fine teeth cut in their outer peripheries which are adapted to mesh when there is no hosiery blank in the machine.
  • One of the feeding cups is mounted on a stationary vertical axis and the other of the feeding cups is mounted on a resilient vertical axis so that when a blank is fed between the feeding cups the teeth on the periphery of the feeding cups engage opposite sides of the blank immediately below the selvage edges thereof.
  • the resiliency of one of the feeding cups is adjustable to thereby increase or decrease the pressure exerted on the blank as it is passed between the proximate edges of the feeding cups in a seaming operation.
  • the pressure of the cut teeth on the peripheries of the two feeding cups often severs one or more of the threads in the blank immediately below the seam and thus cause runs and pull threads in the hose.
  • the conventional feeding cups have heretofore, in many instances, caused the selvedge edges of the hose to bunch rup between the feeding cups as they are fed to the same by an operator and the feeding cups would not carry the selvedge edges through the machine properly. This not only causes a number of stitches to be repeated through one point of the stitched edges, but also causes the material which is bunched up between the feeding cups to be torn and thus completely ruin the hose.
