Definitions

  • This invention relates to an apparatus for applying a liquid coating to longitudinally moving, continuousjfilamentary materials and, more particularly to improvements in those portions of the apparatus which pick up and transfer the liquid coating material'from a'supply to the filamentary material itself.
  • Continuous glass fiber strands in many commercial installations are produced by maintaining asupply of molten 'glass inaglass melteror bushin'g" which has a plurality of minute orifices distributed over its bottom. A fine "stream of glass flows through each or the orifices and the cooling streams "are longitudinallydrawn '-at high speed'to'attenuate them into' glass fibers.
  • Coin- 'mercial bushings usually have upwards of 200 orinore orifices or tips through each of which an individualfi'lament is pulled and the filaments are combined by lateral association to form a single strand.
  • the 200 -'or-rnoi'e orifices or tips are spaced over'a considerable-area and the filaments, therefore,-extend in theshape of a fan leading from the spaced orifices to a guide or gathering shoe.
  • the instant invention has as its primary object-the provision of means or apparatus for applying the liquid coating to each of the individual filaments prior'to' their association in a strand.
  • 'It is a further object of thisinvention to providean apparatus'for applying a liquid coating'to a group-of continuous filaments'so designed as to provide acons'tan't, uniform supply of the coating material and 'to'apply it to each of the filaments with a minimum of interference withor increase in the resistance to the longitudinal movement of the filaments as they are being attenuated.
  • Fig. 1 is :a fragmentary, somewhat diagrammatic view in elevation 'of apparatus embodying the invention :as combined'with filament i-fortning and strand winding apparatus known in the art.
  • Fig. 2 is an end -view"in elevation takenfrom the right sideinliig. 1 and showing only the strand'coating apparatus embodying .the invention.
  • Fig. 3 is a plan view of apparatus embodying the invention.
  • Fig. 4 is'a' fragmentary view-'in-eleva'tion on a greatly enlarged :scale of --a portion of apparatus embodying the invention, specifically illustrating the application of the liquid coating to the filaments and their association to- 'geth'er'to form a strand.
  • Fig. 5 is a fragmentary somewhat diagrammatic vertical "sectional view taken 'generally'along the'line 5-5 of Fig. 3 and, like Fig.4, illustrating the application of coating material'to the filaments.
  • A-multifilament, continuous glass fiber 'strand' may be forme'd'from a plurality of individual fibers 10 attenuated from "fine streams of glass which flow through a corre- Spon'dinghumber 'of orifices in the bottom of 'a glass 'melter'or bushing generally in'dicatedatll. It will be observed inFigs. l and '2 that the fibers or filaments 10 extend in a plurality of lateral rows because (Sf-the neces si ty for'laterally'spacing the individual orifices-from which they are pulled. ln'Fig.
  • the filaments 10 are illustrated as-'extendingtransversely across the bushing -ll'w'vith', sa "-50 or more in each individual row and in Fig. Z' i't 'can'be'se'en that the bushing 11 has four or more rows of filament orifices.
  • Thetransfer belt 23- is mounted upon acrowned drum '26 which is, in turn, supported'by a sha'ft'27 driven fromthe gearing 25 and extending horizontally over the liquid material'supply tank 22'at such a level that the peripheral surface of the drum 26 'dips'beneath the'level of asupply of coating material'generally indicated at 28 in the tank "22.
  • the level of the coating material 28 is maintained by a weir 29 'extending'transversely across the'tank '22 and separating the tankj22 into a supply compartment 30 and an overflow "compartment 131.
  • a coating 'rna'teri'al input line 32 leads to'the bottom of the 'supply'cornpartment 30 .anda return line 33 leadsfrom "the overflow compartment 31 to a pump and supply for "thejcoating material 28, not shown in the drawings.
  • the belt 23 is also engaged over a guide .bar 34 mounted "in a'fra'me '35 and extending parallel to the "axis of the drum 26 above andin 'front of thesupply tank 22. As can best be observed in FigsfB and 5,
  • the drum 26 is rotated at a constant speed so that the belt 23 is moved through the pool of coating material 28 and picks up a layer of the coating substance on its outer surface.
  • the layer of coating material generally indicated at 37 (Fig. maybe leveled by a doctor blade 38, if desired, and is carried forward across the span of the belt 23 and around the guide bar 34 moving in the same direction around the guide bar 34 as the filaments 10.
  • the filaments wipe through the layer of coating material 37 at the point generally indicated by the reference number 39 in Figs.
  • the quantity of material adhering to each of the filaments 10 is referred to as controlled because by proper coordination and relationship of the viscosity, tempera-- 23 and the nose or guide bar 34 to prevent the ingress of contaminants and the cover 40 has a visor 41 which can be swung downwardly and forwardly to the position shown in dotted lines in Fig. 2 to cover the guide bar 34 and the forward .portion of the belt 23 when the apparatus is down 1in. oi:de r ,to preventslugs or beads of glass from striking the belt 23.
  • Apparatus embodying the instant invention has many advantages over previously designed applicators and even over such applicators as may have been employed which utilize a roller for transferring the coating material 'from a supply to the filamentary material to be coated. Among these many advantages the following are included.
  • all of the filaments contact the coating substance for as brief an extent as possible because the passing of each filament into, through and out of the coating substance creates resistance to the movement of the filament and the longer the extent of submersion in the coating material the greater the resistance.
  • all of the filaments should engage the transfer device, in this case the belt 23, as near to tangentially as possible.
  • the transfer device in this case the belt 23, as near to tangentially as possible.
  • the coating device from a number of different positions and some of the filaments will enter the film 37 of coating material before others of the filaments and will remain in the film for a greater extent.
  • the extent of immersion of the filaments in the fllm 37 is far less than it would be, for example, if the filaments were engaged in a film of'coating material 37 moving 'on the surface of a roll having a diameter like thatof the drum 26
  • a coating transfer belt 23 a large area'of pick up around the drum 26 may be submerged in the liquid and a 'small area oftransfr to the filaments around the guide a bar 34 may also be employed.
  • This area of engagement can be kept so small that it need utilize only approximately one-half of the width of the transfer belt 23 and thus when the surface of the transfer belt 23 becomes worn from the abrasive effect of the filaments 10 on the belt 23, it may be slipped off the drum 26 and guide bar 34 and turned over to present a new surface.
  • Utilization of a belt 23 according to the invention also permits a stationary nose or guide bar 34 to be employed, as contrasted to a roller. This is advantageous since it eliminates the necessity for bearings and maintenance and it obviates the close tolerances required in mounting a rotary member to engage the filaments without eccentricity or wobbling.
  • the guide bar 34 though stationary, may be mounted upon an'eccentrie positioning device so that its precise location relative to the filaments 10 can beadjusted to apply proper tension on the belt 23 and to engage the fan of filaments 10 at the most advantageous point and angle.
  • the belt applicator of the invention is particularly effective in use for applying thin coating materials such as size used for treating filaments to be employed in textiles.
  • Apparatus for applying a liquid coating to longitudinally moving, continuous, filamentary material comprising, in combination, a liquid supply tank having an open top, a driven roller journalled on a horizontal axis and positioned with at least a substantial portion of its periphery within said tank and beneath the surface of the supply of liquid therein, means for rotating said roller, a belt guide positioned laterally of said roller, said belt guide having a cylindrically curved outer surface of diameter substantially smaller than the diameter of said roller, a continuous belt extending around said roller and said belt guide and driven by said roller over said belt guide and a filament guide positioned beneath said belt guide for guiding said filamentary ma terial into substantially tangential contact with the outer surface of said belt at the outer side of said belt guide.
  • the belt guide is a non-rotatable cylindrical member having a smooth surface and is located with its outer surface only slightly beyond the edge of said tank and said filament guide is located beneath said guide and laterally beyond the edge of said tank, whereby said filamentary material moves from contact with said belt to said filament guide exteriorly of said tank.
  • Apparatus for applying a liquid coating to longitudinally moving, continuous, filamentary material comprising, in combination, a generally horizontal liquid supply tank having an open top, a driven roller journalled on a horizontal axis and positioned with l at least a substantial portion of its periphery Within said tank and beneath'the level of the surface of the supply of liquid therein, means for rotating said roller, a belt guide positioned laterally of said roller at the side of said tank, said belt guide having a cylindrically curved outer surface of diameter substantially smaller than the diameter of said roller, a continuous belt extending around said roller and said belt guide and driven by said roller over said belt guide, a filament guide positioned outside said tank and beneath the outer side of said belt guide for guiding said filamentary material into contact with the outer surface of said belt at the outer side of said belt guide and means for circulating liquid coating into and out of said tank.
  • Apparatus for applying a liquid coating to longitudinally moving, continuous, filaments comprising, in combination, a liquid supply tank having an open top, at least two cylindrical elements mounted on spaced, parallel, horizontal axes, an applicator belt extending around said elements, one of said elements being located above said tank at such a level relative to its diameter that at least a portion of said belt extends beneath the surface of the liquid supply in said tank,
  • another of said elements being located laterally of the 'fir'stmentioned element at such distance therefrom that at least a portion of said belt passing around said other element extends horizontally beyond the edge of said tank, the diameter of the second-mentioned one of said elements being small whereby movement of said filaments through a film of liquid on said belt enroute to and from substantially tangential contact with said belt is of short duration, at least one of said elements being rotated under power for driving said belt around said elements in a direction moving up over the first mentioned element, generally horizontally to and down around the second mentioned element, and means for guiding said filamentary material into substantially tangential contact with the outer side of said belt at the outer side of the second mentioned element.
