Definitions
- ABSTRACT Apparatus for continuously impregnating a textile fiber assembly or'arrangement with a liquid comprising a pair of discs and two cover plates arranged at the face'sides or end faces of the pair of discs.
- the cover plates together with the discs form a pressure zone.
- a collecting or compacting zone is arranged in front of the pressure zone as seen in the direction of the flow of the fiber arrangement.
- the cover plates in the region of pressure zone, and as seen in the direction of flow of the fiber arrangement, are inclined towards the face sides of the pair of discs.
- the present invention relates to a new and improved apparatus for continuously impregnating a textile fiber assembly or arrangement with a liquid.
- fiber assembly or arrangement is intended to designate natural as well as man made stable fibers, such as delivered in the form of a continuous fiber arrangement or structure, e.g. as card or drawframe sliver or as web at the delivery zone of a drafting arrangement. Also, these terms are intended to designate bundles of endless filaments.
- liquids as employed herein, is intended to designate water or other solvents or any solutions, dispersions and emulsions of any substances (e.g. adhesives, colorants, etc.) in water and/or other solvents.
- impregnate is intended to designate the covering or coating of the individual fibers of the fiber assembly with a liquid coat as well as homogenous, fine droplet-shaped distribution of the liquid throughout the fiber assembly, or combination of both.
- the lateral cover plates enclosing the pair of discs with a small clearance are provided with openings at the region of the face sides or end faces of the pair of discs for the introduction of impregnating liquids.
- the openings for infeeding the liquid can merge into liquid distribution grooves, these grooves being shaped as converging recesses extending outside the pressure zone to the middle of the pressure zone.
- Another and more specific object of the present invention relates to an apparatus for impregnating textile fibers in an extremely reliable and efficient manner, wherein the apparatus itself is of relatively simple construction and design, not readily subject to malfunction or breakdown, and requires a minimum of maintenance and servicing.
- the inventive apparatus for continuously impregnating a textile fiber assembly or arrangement with liquid embodying a pair of discs and two cover plates arranged at the face sides or end faces of the pair of discs, and forming a pressure zone together with the discs, and having a collecting or compacting zone arranged in front of the pressure zone, as seen in the direction of the flow of the fiber arrangement, eliminates the abovementioned disadvantages in that the cover plates in the region of the pressure zone and as seen in the direction of the flow of the fiber arrangement are inclined towards the face sides or end faces of the pair of discs.
- the inclination of the cover plates can also extend over the collecting or compacting zone. According to a further embodiment of the invention the inclination can also extend further than or past the pressure zone.
- liquid infeed or inlet openings there can be provided at the inclined cover plates, or at a suitable region of the inclined cover plates there can be provided liquid infeed or inlet openings and the inclined portion of each cover plate can be formed by an insert member.
- FIG. 1 illustrates an apparatus for continuously impregnating a fiber assembly with liquids and shown in cross-section, taken substantially along the line II of FIG. 2;
- FIG. 2 is a cross-sectional view of the apparatus depicted in FIG. 1, taken substantially along the line lI-II thereof;
- FIG. 3 is an alternative embodiment of the apparatus shown in FIG. 1, in cross-sectional view taken substantially along the line III-III of FIG. 4;
- FIG. 4 is a cross-sectional view of the apparatus depicted in FIG. 3, taken substantially along the line IVIV thereof;
- FIG. 5 is a further variant construction of apparatus depicted in cross-sectional view, taken substantially along the line V-V of FIG. 6;
- FIG. 6 is a cross-sectional view of the apparatus depicted in FIG. 5, taken substantially along the line VIVI thereof.
- the apparatus for continuously impregnating a fiber assembly or arrangement as depicted in FIGS. 1 and 2 consists of a pair of discs 1 and 2 of the same diameter and lateral cover plates 3 and 4.
- the cover plate 3 is mounted at the machine frame (not shown).
- the discs 1 and 2 are rotatably and axially movably supported in the cover plates 3 and 4.
- the disc 2 is subjected to a suitable load or biasing force and thus is pressed against the disc 1 and adapting itself to the cross-section of the fiber material passing through a pressure zone, generally indicated by reference character 50 in FIG. 1.
- each cover plate 3 and 4 there is defined the pressure zone 50 of a length D, a collecting or compacting zone 51 located in front of the pressure zone 50 in the input quadrant and of length E, and a delivery zone 52 following the pressure zone 50 in the delivery quadrant of a length F and extending to the delivery point 5 of the material.
- the term input quadrant and delivery quadrant respectively designate the quadrant of the cylindrical surface of the discs 1 and 2, each of which face a fiber assembly entering or delivered respectively from the apparatus.
- the collecting zone 51 consists of a respective half of a funnel 6 and 7 arranged at the cover plates 3 and 4 respectively.
- the two cover plates 3 and 4' are mutually maintained at a distance from one another by means of spacer pins 8 or the like and are rigidly held together by screws 8a or equivalent fastening devices, as best seen by referring to FIG. 2.
- the clearance or spacing between the surfaces of the discs 1 and 2 in the pressure zone i.e. the thickness of a fiber assembly compressed between the discs 50, designated by reference character a in FIG. 1, is a function 1 of a number of variables, for example the mass of fiber material per cross-section of the fiber assembly, the pressure applied between these discs, the specific weight of the fiber material, of the elastic properties of the discs, the liquid content of the impregnated fiber assembly, etc.
- the cover plates 3 and 4 are inclined towards the face sides or and faces 53 of the pair of discs 1 and 2 (FIG. 2).
- each cover plate 3 and 4 liquid inlet or infeed openings 9 and 10 respectively through which impregnating liquid can be brought or injected at low pressure into the tapered spaces or clearances 54 formed by the inclined surfaces of the cover plates 3, 4 and the discs 1 and 2.
- the discs 1 and 2 are of a width or thickness b.
- the cover plates 3 and 4 are provided with a surface 11 and 12 respectively, inclined with respect to the corresponding end faces 53 of the discs 1 and 2 and extending up to the smallest mutual spacing or distance 0 between the cover plates at the point of delivery 5, said distance r: advantageously being chosen to be somewhat larger than the width b of the discs, so as to provide a clearance being adequate for rotation of the discs I and 2.
- the distance 0 can be chosen for instance, according to the viscosity and the type of liquid employed, the elasticity of the disc material, the pressure applied between the discs 1 and 2, approximately within the range of (b 0.01 mm) to (b 0.3 mm).
- the surfaces 11 and 12 respectively of the cover plates 3 and 4, respectively, are inclined with respect to the face sides or end faces 53 of the pair of discs 1 and 2 atan angle a, which for achieving the desired taper effect is, for example, larger than 3 and smaller than 30.
- the inclined surface 11 or 12 respectively of the cover plate 3 or 4 respectively can be covered by a coating material, such as hard metal, ceramics, sapphire, ruby and synthetic hard stones, which is harder than the rest of the corresponding cover plate so that there can be prolonged the life of the gliding zones of the cover plates 3 and 4 loaded most by the fiber assembly and the zones at which the flange pressure of the elastic discs 1 and 2 against the cover plates 3 and 4 is greatest.
- the inclined surface 11 and 12 respectively of the cover plate 3 or 4 respectively can be realized by localized shaping or configuring of the cover plates having otherwise parallel surfaces.
- FIGS. 1 and 2 functions as follows: A continuously infed fiber assembly or arrangment 13, supplied from above in the direction of the arrow depicted in FIG. 1 (the path of the material is shown interrupted for better clarity), is col lected in the collecting zone 51 by means of the funnel 6, 7 formed by the two funnel halves 6 and 7, and in the adjacent pressure zone 50 is strongly compressed. Through the openings 9 and 10 respectively of the cover plates 3 and 4 respectively there is introduced an impregnating liquid and owing to the rotational motion of the discs 1 and 2 this liquid is entrained in the direction of the arrows by the friction at the disc faces and is transported into the increasingly converging space or room 54.
- the impregnating liquid laterally emerges at the input quandrant of the discs 1 and 2 at their end faces and surrounds the continuously supplied fiber assembly in the funnel 6, 7 of the collecting zone 51.
- the fiber assembly is subsequently compressed in the pressure zone 50 during which process excessive liquid contained in the pressure zone 50 laterally escapes over the funnel halves 6 and 7.
- the impregnating liquid tends to escape laterally towards the center and the periphery of the discs. This occurs in the input quadrant of the discs as well as in their delivery quadrant below the line connecting the centers of the disc axes 8' and 8", i.e. in the lower part of the pressure zone 50 and in the adjacent delivery zone 52.
- the liquid which is continuously expelled at the disc periphery over the full length thus prevents any jamming of fibers between the disc end faces 53 and the cover plates 3 and 4 so that formation of beards is also prevented in the delivery quadrant.
- the fiber assembly upon passing the delivery point 5 can leave the impregnating apparatus freely or under tension in the form of an impregnated compact fiber assembly or arrangement 14.
- the impregnating apparatus shown in FIGS. 3 and 4 constitutes an alternative embodiment of the apparatus from that considered above with respect to FIGS. 1 and 2, identical elements having been generally indicated by the same reference characters.
- This variant form of apparatus contains a pair of discs 15 and 16 and lateral rigid cover plates 17 and 18, the cover plate 17 here also, like the cover plate 3 shown in FIG. 1, is mounted at the machine frame (not shown).
- the discs 15 and 16 and the cover plates 17 and 18 correspond in their functions exactly to the discs 1 and 2 and the cover plates 3 and 4 shown in FIGS. 1 and 2 and thus are not again here described in detail.
- the impregnating apparatus according to FIGS. 3 and 4 also contains a pressure zone 50 of the length D, a collecting or compact ing zone 51 of the length E containing the funnel halves 19 and 20 respectively, and a delivery zone 52 of the length F.
- the apparatus according to FIGS. 3 4 differ from the one shown in FIGS. 1 and 2 in as much as the cover plates 17 and 18 are maintained at a mutual spacing or distance not by spacer pins but in this case by two tapered intermediate plates 21 and 22.
- the cover plates 17 and 18 and the intermediate plates 21 and 22 are fastened together by screws 23 or the like and thus form a unit.
- the discs 15 and 16 are inserted into the tapered or wedge-like clearance space or room 54 formed between the cover plates 17 and 18 left open between the intermediate plates 21 and 22. Seen in the direction of movement of the material, the intermediate plates 21 and 22 extend to a material delivery edge 24.
- the fiber assembly leaves the impregnating apparatus and here the distance c between the intermediate plates 21 and 22 is smallest and only somewhat larger than the width b of the discs 15 or 16 (analogous to the arrangement shown in FIGS. 1 and 2).
- the cover plates 17 and 18 also in this case are provided with two liquid input openings 25 and 26 each of which is located in the input quadrant.
- the impregnating liquid as described with reference to the embodiment of FIGS. 1 and 2, is introduced via these openings 25 and 26 into the clearance space formed between the disc end faces and the cover plates.
- FIGS. 5 and 6 A further variant of the inventive apparatus is depicted in FIGS. 5 and 6.
- This embodiment of apparatus also corresponds to the one shown in FIGS. 1 and 2, as it contains a pair of discs 28 and 27 and then laterally arranged rigid cover plates 30 and 31 maintained at a mutual spacing by spacer pins 29.
- This apparatus basically differs from the one shown in FIGS. 1 and 2, in as much as each cover plate 30 and 31 respectively, contains an insert or inset member 32 and 33 respectively, at the region of the pressure zone 50.
- These insert members 32 and 33 are, as viewed in the direction of passage the fiber material inclined towards the end faces 53 of the discs 27 and 28.
- insert members 32 and 33 are of, for instance rectangular shape, and their dimensions are chosen such that, seen in the direction of passage or flow of the fiber material, they extend over the pressure zone 50 and the entire collecting zone 51 and that, seen transversely or at right angles thereto, practically the entire space between the disc axes of the pair of discs 27 and 28 is covered by the insert members 32 and 33.
- the insert members 32 and 33 also can be of any other suitable shape.
- the embodiment according to FIG. 5 also differs in that the insert members 32 and 33 are provided with grooves 34 and 35 which are radially arranged around the disc axes. These grooves 34 and 35 are flow connected with liquid input or infeed openings 36 and 37 respectively, arranged externally of the in sert members 32 and 33 respectively.
- the insert members 32, 33 can be fabricated from a material which is harder than the material of the corresponding cover plates 30 and 31, for instance from hard metal, ceramics, sapphire, ruby or other synthetic hard stones.
- the life span of the inventive impregnating apparatus thus can be substantially prolonged, as the harder materials are more slowly worn by the passing fiber assembly and such inserts can be exchanged whenever they are worn.
- the life span also can be prolonged by covering the region of the cover plates in the region of the pressure zone with a coat of a material which is harder than the material of the other zones of the cover plates. Once this coat or coating is worn, only such coat must be renewed and the apparatus is again ready for use.
- the axial dimension b of the discs is by no means limited to the proportions indicated in the drawings, and they can be chosen to.be much larger, i.e. a multiple of the diameter. This choice, of course depends on the fiber assembly or arrangement to be processed.
- An apparatus for continuously impregnating with a liquid a textile fiber arrangement moving in a predetermined direction of travel comprising a pair of rotatable discs having peripheral faces and end faces, two cover plates arranged at the region of the end faces of said pair of discs, said discs being arranged with said peripheral faces opposite to each other, including a liquid infeed opening in each of said cover plates, said liquid infeed openings, viewed in the direction of travel of the fiber arrangement, being located in front of a line connecting the axes of said pair of discs, said two cover plates together with said pair of discs forming a collecting zone into which impregnating liquid is delivered from said infeed openings of said cover plates, said cover plates, viewed in the direction of travel of the fiber arrangement, having portions inclined towards the end faces of said pair of discs and extending beyond said collecting zone for forming wedge faces covering the end faces of said pair of discs after the collecting zone.
- predetermined localized regions of said cover plates are configured to provide said inclined portions to effect the inclination of said cover plates towards the end faces of said pair of discs.
- each of said insert members consists of a wear-resistant material.
