Definitions

  • the web 31 enters the air-tight enclosure 60 through the opening 70 and through the nip of the rolls 72, 73.
  • the web 31 then falls onto the conveyor 74 and, as it moves laterally, passes underneath the first discharge of powder caused by the action of the brush 114 against the roll 112.
  • the web 31 now carried by the conveyor 74 ' passes underneath the wand 86 thereby receiving a second dose of powder.
  • the web 31 is then turned downward and around on an axis perpendicular to the direction of move-, ment of the web 31, until the web 31 is moving in a reversed direction and passes onto the foraminous belt of conveyor 78.
  • a powder which is a copolymer of vinyl chloride and vinylidene chloride available from the Dow Chemical Company, Midland, Michigan, under the designation Saran Resin 506 is added to a fibrous web in the manner described above with respect to the drawings.
  • This copolymer has a weight ratio of vinyl chloride to vinylidene chloride of 10:90, a chlorine content of 71%; a plasticizer content of 1%; a minimum particle size of 2 microns, a maximum particle size of 50 microns, and an average size of 11 microns.
  • the powder is added at a rate such that it increases the weight of the web by 15%.
  • the oven temperature is 425°F.
