Definitions

  • This invention relates generally to apparatus and methods for making filter cartridges, and particularly to apparatus and methods for making filter cartridges wherein finely pulverized dry thermo-setting resinous materials are dispersed throughout a fibrous mass, which is then subjected to heat until the materials are thermo-set.
  • the porous filter cartridge is made in continuous lengths by unrolling a band 11. of felt, or other loose fibrous material of suitable character from a spool 12 and leading it across an anvil 13. As, the band 11 moves across the anvil 13, a hopper 14 discharges from its lower end on to the surface of the band 11, a finely pulverized, or pulverulent dry, thermo-setting resinous material 15.
  • Phenolforrnaldehyde resins are most suitable for this purpose and there are numerous kinds as, for example, Bakelite (Union Carbide), Durez (Hooker Chemical Co.).
  • the finely pulverized dry thermo-setting resinous material lies on the surface of the band 1.1, which is moving toward a high speed beater 16.
  • the high speed beater 16 is attached to an arm 17 mounted eccentrically to the crank shaft 18 of a motor.
  • the beater 16 repeatedly pounds the resin 15, which penetrates the interstices of the fiber of the band 11.
  • the band 11 is a relatively dense fibrous mass of felt, or other suitable material, and it is compressed by the high speed beater 16 so that any air in the interstices may be momentarily squeezed out during the compression phase, and
  • the resin under heat becomes plastic, flows and invests the material surrounding it by coating individual filaments particularly at their cross over points, where they become linked when the resin polymerizes into an insoluble rigid set form.
  • the strip 11 is drawn from the impregnation station by variable speed feed rollers 31, which pull the strip through the oven 30.
  • the strip 11 is first formed into a cylinder as it moves into a cylindrical guide (not shown) leading it through the oven 30'.
  • the pulling rollers 31 Upon departure from the oven, the pulling rollers 31 carry it to a point where the strip 11 may be cut into suitable lengths.
  • a method for making porous filter cartridges comprising:
