Definitions

  • the part of the apparatus for this portion of the manufacture customarily consists of a system of pairs of rolls in front of which and, if desired, between which there are arranged blower nozzles. While the pairs of rollers have the function of loosening the stuck together fibers by means of mechanical pressure, the loosening up of the fibers with the aid of the blower nozzles is accomplished by means of a more or less undirected gas stream.
  • Nozzles of this kind for example, consist of a plate having long slits that extend at right angles to the direction of movement of the strand. This plate rests as a closure upon the wide end of funnel-shaped air supply lines.
  • FIG. 3 shows how a strand of fiber 11 is pulled off from a ball or source of strand 12 in the direction of the arrow.
  • the fiber strand runs over a direction reversing device 13.
  • the blower nozzle 14 [consisting of elements 110].
  • the fiber strand 11 now runs at constant speed through the chamber (recessed portion) 10 of the blower nozzle, whereby air or some other gas under pressure is introduced into the funnel 1 and through the holes 4.
  • the strand of fiber is loosened up and broadened out in this operation.
  • the loosened up and broadened out fiber strand runs over the reverse direction roller 13 and between two pairs of rollers 15 and 16 into a spray chamber 17.
  • this spray chamber 17 there is sprayed on to the fiber strand a softener by means of two opposed spray nozzles 18.
  • the fiberstrand which has been moistened (wetted) with the softener is now worked up into filter rods.
