Definitions

  • the strands of glass are first coated with a liquid, for instance a lubricant, prior to their delivery to the drawing drum, and the glass fibers formed on the drawing drum are then coated in a separate application, while separated from each other, with a liquid coating medium after their removal from the drawing drum and prior to their consolidation into a glass fiber structure.
  • a liquid for instance a lubricant
  • An apparatus for carrying out the second coating application includes an air channel leading away from the drawing drum and liquid transfer means protruding into the air channel so as to be contacted by the glass fibers carried through said air channel in a stream of air.
  • Glass fiber structures are usually made by first forming filaments of glass in a continuous process from streams of liquid or softened glass by means of a drawing drum rotating at high speed. Before a complete revolution of the drum is eifected with the filaments of glass laying side by side on it, they are lifted from the drum by a scraper or stripper and at that time split up into staple fibers of uneven length. The thus-formed fibers are then suspended in a stream of air, are conducted along guide walls and finally, after elimination of the air, consolidated to the fibrous structure desired as end product at a place remote from the drawing drum.
  • the final product may for instance be a plane fibrous structure such as a mat or fleece or it may be a ribbon-shaped structure such as a sliver or a yarn, or it may also be a three-dimensional body such as tube sections (see German Pats. 824,456 and 976,782).
  • Both the filaments and the subsequent fibers must be coated with a liquid medium in order to effect the taking with or driving of the filaments by the drum and in order also to form the final body from the fibers.
  • the filaments are usually coated on the way from the spinning place to the place where they first touch the drawing drum.
  • the conventional device for this purpose is a pad which extends across the width of the moving filaments or across the width of the drawing drum and consists of an absorptive material.
  • This pad is placed in a manner that the sidewise aligned filaments will contact it if possible under tension.
  • the pad is soaked with the liquid to be coated.
  • the pad can also consist of a cloth supported on a rod and may be supplied with fresh liquid by a dropping device in accordance with the amount of use. For the practical execution of these devices it is not easy to transfer the liquid from the pad to the filaments which are drawn off at a high speed, that is above 2,900 m./min. There have been many proposals for devices of this kind. The one most successful is that published in Austrian Pat. 218,191.
  • the coating of the filaments taken by the drum with a liquid which in industrial practice is called oiling has a triple function.
  • One purpose is to impart to the filaments an adhesion to the surface of the drawing drum during the high speed revolution, which adhesion must be sufficient to prevent slippage between the single filament and the drum surface.
  • the coating should in addition make the individual glass filaments supple and flexible to prevent abrasion or other mechanical damage during the further processing.
  • the glass fibers or staple fibers which are formed from the glass filaments in the subsequent processing and are consolidated to the glass fiber structure, for instance a sliver or a fleece, must in addition obtain a certain tensile strength which is secured by the cohesion or adhesion between the fibers.
  • liquid coating material may also be used for other reasons, for instance in order to dye the glass fiber structures.
  • the coating medium mostly of the emulsion type consists of different organic or inorganic oils and additives which stabilize the emulsion, increase the flexibility of the filaments drawn, and have an adhesive, hardening and antistatic effect.
  • flexibility is a feature which mainly concerns the drawing of the filaments by the drum and their taking-off therefrom
  • the adhesive nature of the coating medium is a property, which brings disadvantages for the drawing drum and the stripper insofar as their surfaces get sticky and dirty therefrom.
  • the lubricant which then sticks to the drum surface has a tendency to soil the surface and it also decomposes because of the continuous friction between the stripper and the drum.
  • residues are formed on the drum and on the stripper which interfere with the further drawing of the fibers by the drum and the splitting of the filaments to individual fibers.
  • the residues which are finely divided and mixed with minute parts of the filaments themselves form a kind of emery paste which is harmful to the surface of the drum and makes it progressively less suited for further formation of fibers.
  • the problem thus, is either to spare the surface of the drum by too low an amount of coating liquid and, in that case, to provide for too small a dose of liquid for the fibers to improve their cohesion, or on the other hand, to use an overdose which will result in the necessity to discontinue the production from time to time to clean the drum surface and the stripper.
  • Too low or too large an amount has also an undesirable effect on the spinning process itself, that is on the formation of the filaments on the spinning cones at the heated end section of glass rods or under the spinning nipples of the trough or channel which contains the liquid glass.
  • the attenuation and drawing on the drum is also affected thereby. Whenever the filaments received on the drum have too little coating liquid, they will not adhere sufiiciently to the drum surface and will then be drawn with uneven thicknesses because of the slippage. This again results in deviations of the diameter of the filaments and causes the jerky drawing of the filaments by the drum which thus may be subject to tearing or if the taking ofr is interrupted for just a brief instant, may be subject to burning away during taking-01f.
  • the soiling of the drum surface and of the stripper has also a bad efiect on the spinning process since the filaments will be liable to more or less float on the drum surface which again results in an uneven thickness of the filaments or fibers.
  • An adequate and sufliciently distributed lubricant is mainly indispensable in the manufacture of glass fibersli vers with respect to the uniformity and the tensile strength of such a silver and the yarn eventually twisted from the sliver.
  • the uneven amount of lubricant in particular results in an uneven strength which again causes uneven tensioning in the further processing and thus a yarn of uneven properties.
  • Another purpose is a process of this kind wherein a soiling of the drum surface or stripper is avoided.
  • Another object of the invention is a coating process and apparatus for it wherein fibers of even thickness and uniform properties can be produced, and in particular where in case of fibrous structures the fibers in the interior of the structures have the same properties as at the surface.
  • the invention also embraces an apparatus for applying a liquid coating medium to glass fibers, the apparatus comprising a drawing drum for attenuating the glass filaments to individual glass fibers, guide walls forming an air channel of a width extending substantially across all of the periphery of the said drum and of a general axial direction tangentially away from the periphery of the drum, means for generating a stream of air in said channel for carrying the fibers away from said drum, and liquid-transfer means projecting into the said channels so as to protrude into the paths of the fibers carried by said stream of air.
  • FIG. 1 illustrates in a partial cross-section and on a reduced scale an apparatus for making a flat fiber body such as a fleece or a mat;
  • FIG. 2 is a partial vertical section through another embodiment of the invention, the apparatus of this figure being useful particularly for making a ribbon-shaped fiber structure;
  • FIG. 3 a partial vertical section through another embodiment of the invention showing this embodiment in a partial view in the same manner as in FIG. 2.
  • the process of the invention is characterized by the fact that the coating of the filaments being continuously drawn on the one hand, and of the individual fibers generating of the filaments on the other hand, is practiced in two separate application steps. .As will be described further below, the coating may be effected, in case of the fibers, by carrying the fibers in an air stream along guide walls and bringing them into con tact with coating means which protrude into the air stream and apply a coating before and while the fibers are consolidated to a fibrous body.
  • the fibers are thus coated separately from the filaments and, if wanted, different coating materials may be used, such as lubricants, adhesives, binders, dyes, etc. It is not necessary, during coating of the fibers, to take into account the requirements of the spinning process for the filaments, but rather the second coating may be directed only to the final use and processing of the product formed by the fibers. It is furthermore possible with this type of procedure to keep the surface of the drum clean from the lubricant for the further taking-oil of the filaments and also to apply the coating in exactly the amounts that are necessary.
  • the device comprises a drawing drum 1 that rotates with high speed and onto which are propelled the filaments f in parallel alignment and in a very large number, for instance up to 500, after being coated by a coating device d of conventional structure, for instance a coating ledge, to a degree adequate to secure the adhesion of the filaments to the drum with the coating device d several rows of fibers can also become forced, as shown into one plane 1''.
  • the filaments are then attenuated on the drum and conducted to the stripper 2.
  • This movement is effected partly in direct contact with the surface of the drum and partly within an area of rotation which is generated by the revolving drum and carries the filaments within the adjacent layer of air that revolves with the drum.
  • the stripper 2 extends tangentially or close to tangentially from the periphery of the drum and is secured on a pivot axis 3.
  • the drum 1 moves in a housing which partly encircles the drum and may be called the apron and which confines the area of rotation close to the drum surface.
  • This apron is formed by the wall indicated as 4 in the drawing.
  • a turn member for change of direction is formed by the continuation of the channel formed between the drum surface and the interior of the apron wall. This turn member is indicated as 5 in the drawing and connects with an adjacent guide wall 6 which will cause the fibers to move to the place where they are consolidated to a fibrous structure.
  • the filaments which move when the drum 1 revolves in the direction of the arrow A and which are, after completing less than one revolution, taken off from the drum, are then split up during the take-off into fibers of uneven length moving in an air stream S.
  • a revolving coating roller 7 the direction of revolution indicated by the arrow B.
  • this roller is provided at the turn member 5, but it could also be provided in the horizontally extending guide wall 6.
  • the coating roller either dips into a receptacle for the liquid medium or as shown is supplied continuously with the medium by means of a dripping or spraying device 8..-
  • the roller 7 has an axis 9 which is supported outside of the turn member 5.
  • the roller extends through a gap in the wall of the turn member into the interior of the air channel with a portion of its circumference indicated as 10.
  • the roller interrupts the guide wall formed by the turn member and the guide wall 6.
  • the individual fibers must therefore pass the surface of the coating roller and come into contact therewith and thus will carry away the necessary amount of liquid coating medium.
  • the individual fibers receive a sufficient amount of coating medium between the place of their formation on the drum and the place of their consolidation to a fibrous structure.
  • all of, or practically all of the fibers in the final product will be coated adequately with the liquid coating medium, and the amount of coating will not depend upon their relative position in the fiber structure or on the amount of coating applied to the intermediate product consisting of the glass fibers.
  • FIG. 2 shows in schematic form an embodiment wherein a cylinder 21 is provided with a transfer elements 28 to form a strip of absorbent material, for instance a felt, which extends through a gap into the cylinder 27 and is supplied from the exterior with liquid.
  • the felt 28 extends to an extent into the interior 29 of the cylinder that the fibers, which move into the cylinder along the curved guide wall 30 and form a vortex w along the inner surface of the cylinder, will contact the inner edge 31 of the felt 28 and absorb liquid therefrom.
  • the felt 28 can be supported in a housing 32 and may receive its liquid from a receiver 33 provided at the outer end of the housing. The amount of wetting of the fibers will depend on the absorptive properties of the felt, on the level of treating liquid in the receptacle 3'3 and on the length of protrusion of the portion 31 of the felt.
  • FIG. 3 illustrates still another embodiment which may be used in producing staple fiber slivers and which is of a particularly simple design requiring very little service.
  • This embodiment in addition permits an uninterrupted and particularly well adjustable wetting of the fibers.
  • the cylinder 27 in this case is provided with a slit-shaped opening 35 that extends through its entire width or through the major parts of its width.
  • the liquid transfer medium itself is disposed or suspended in this slit and thus protrudes into the cylinder 27.
  • the member in the form of a shelf is indicated by the reference numeral 36.
  • a particcularly useful form of transfer medium is a wire mesh of narrow openings which may for instance be fastened to a support tongue or shaft 37.
  • the interior end of the support member and wire mesh may be slightly bent inwards in order to present an obstacle to the fiber stream and to make sure that the fibers will contact the wire mesh.
  • This type of a fine mesh wire sieve has the advantage of little service and longer life as against a felt which will be subject to wear after an extended time of operation and which also may be liable to rigidify and harden because of the clogging up with particles of the liquid medium which do not evaporate.
  • this kind of embodiment is a further means to avoid variation of the coating liquid in the fiber product, such as a sliver of glass fibers, which may still occur with the use of a felt.
  • the wire mesh which is secured to a support tongue is of almost unlimited durability and can easily be cleaned by washing in case of soiling.
  • the liquid is supplied to the transfer element through a dropping device 38.
  • the coating liquid may for instance comprise an adhesive or a dye.
  • the wire mesh in this case has the function to distribute uniformly the applied coating liquid and to keep it available while, with the use of a smooth surface, the coating liquid may be subject to uncontrolled draining or dripping.
  • a hinge 39 permits to snap open the portion 40 of the cylinder for cleaning or similar purposes.
  • a process of making glass fiber structures the steps of passing glass filaments over a drawing drum to attenuate the filaments; lifting the attenuated filaments from said drum and separating the same into individual fibers; transporting said individual fibers separated from each other in an air stream away from said drum; applying a coating liquid to said filaments prior to their delivery to said drawing drum; and applying a further coating liquid to said individual fibers while they are transported by said air stream and prior to their consolidation into a glass fiber structure.
  • the glass fiber structure is a glass fiber mat, fleece, sliver, or threedimensional body.
  • a combination comprising a rotating drawing drum for attenuating glass filaments to individual fibers; means for applying a coating liquid to the filaments upstream of said drawing drum; guide wall means forming an air channel of a width substantially equal to the length of said drum and leading in substantially tangential direction away from the periphery of said drum; means for generating a stream of air in said channel for carrying the fibers separated from each other away from said drum; and coating liquid transfer means projecting into said channel so as to protrude into the path of the fibers carried by said air stream to apply a coating liquid to the individual fibers while they are transported by said air stream.
  • channel-forming guide walls comprise a cylinder and wherein a gap is provided in the peripheral Wall of said cylinder, said transfer means protruding through said gap into the interior of said cylinder.
  • the transfer member is in the form of a strip of absorptive material extending with one edge into the cylinder through the periphery thereof.
  • said shelf is in the form of a support member and including a wire mesh secured to the top side of said support member.
