Definitions

  • an object of the present invention to provide means for applying an accurately predetermined amount of liquid conditioning agent to a moving strand in a-uniformmannerL
  • Another object of this invention resides in applying a uniform amount of a liquid conditioning agent to a moving strand which may be moving at varying rates of speed or have varying geometrical configurations.
  • Other objects of this invention will be apparent from a consideration of the following detailed description.
  • liquid conditioning agent is stored in liquid storage tank 10.
  • Tank 10 is, in turn, connected to metering pump 1'3 and then to liquid reservoir 12 by conduit means 11.
  • a liquid applicator roll 14 is rotatably mounted in reservoir 12 so that it is partially immersed in the liquid.
  • a pressure responsive control system consisting. of a pressure transducer 23 and the variable speed control unit 24 for motor 18.
  • Line voltage is delivered via leads 25 to the control system.
  • motor 18 changes speed which in turn changes the speed of roll 14. If the level'in the reservoir rises, this indicates that an insufiicient amount of liquid is being applied to strand 15. Accordingly, the speed of roll 14 is automatically increased. Similarly, as the liquid level falls, the speed of roll 14 is decreased.
  • the control'system is sensitive enough to maintain an essentially constant level in the reservoir.
  • a 3.0 denier (0.33 tex.), 126,800 filament acrylonitrile fiber tow was passed at a speed of 200 .yards per minute across the surface of an applicator roll having a diameter of two inches.
  • the reservoir con tained a conditioning agent consisting of a mixture o fatty esters and adiphatic hydrocarbons having'an average kinematic viscosity of eight ccntistokes.
  • the conditioning agent was metered at a rate of 136 grams per minute by a positive displacement pump tothe reservoir.
  • the conditioning agent was removed by solvent extraction from sections along the tow to determine the uniformity of application in each test. It was found that a 30% improvement in uniformity was obtained using the apparatus of this invention.
  • the'combination comprising a liquid reservoir having an applicator roll rotatably mounted therein, a liquid supply tank, conduit means connecting saidreservoir and said tank, a pump disposed in said conduit means for forwarding liquid from said tank to said reservoir, forwarding means for moving said filamentary material across said roll, and driving meansfor rotating said roll, said forwarding means being operatively connected to said pump to provide a rate of flow of liquid from said tank to said reservoir proportional to the speed of travel of said filamentary material, control means responsive to the level of the liquid in said reservoir opcratively connected to said driving means for increasing and decreasing the speed of said roll.
  • Apparatus for applying liquid to a moving strand of filamentary material comprising a liquid reservoir, an applicator roll rotatably mounted in said reservoir, a liquid supply tank, a pump in Communication with said tank and said reservoir, means for forwarding said strand across the surface of said roll, said forwarding means being drivingly connected to said pump to provide a rate of flow of liquid from said tank to said reservoir proportional to the speed of travel of said strand, means for driving said roll, and means for automatically increasing and decreasing the speed of said roll to apply a uniform amount of liquid to said strand.
  • Apparatus for applying a predetermined amount of liquid to a moving strand of filamentary material comprising a rotating applicator mounted in a liquid reservoir. means for moving said strand across said applicator. means for supplying liquid to said reservoir at a rate proportional to the speed of travel of said strand. means for driving said applicator, and automatic control means responsive to the level of the liquid in said reservoir for increasing and decreasing the speed of rotation of said applicator.
  • apparatus for applying a liquid to a moving strand comprising 'an applicator roll rotatably mounted in a liquid reservoir, a supply tank in communication With said reservoir, means for forwarding said strand across said roll, a pump for forwarding liquid from said supply tank to said reservoir at-a rate proportional to the rate of travel of said strand across said roll, a variable speed motor for driving said roll.
  • a pressure transducer connected to the bottom of said reservoir, and voltage control means operatively connected to said pressure transducer and to said motor for varying the speed of said roll in response to changes in pressure in said reservoir.
  • a method of applying to a continuously moving web of material a prescribed amount per unit length of a given substance comprising the steps of moving said web in arcuate contact with part of the surface of a driven roller another part of which dips into a reservoir normally containing a prescribed amount of said substance, feed- F alteration being an increase in the speed of said roller when the amount'of substance in the reservoir increases above the prescribed amount and a decrease in the speed of said roller when the amount of substance in the reservoir decreases below the prescribed amount.
  • Apparatus for applying to a continuously moving web of material a prescribed amount per unit length of a given substance comprising a reservoir normally containing a prescribed amount of said substance, a driven furnishing roller mounted for rotation with the lower part of its periphery dipping into said reservoir, means for progressing said web of material with one side thereof in arcuate contact with the upper part of the periphery of said furnishing roller.
