Definitions
- This invention relates to apparatus and method for coating moving webs wherein fluid coating material is applied in excess; the excess material being distributed across the web and then removed from the coated surface. It relates further to coating apparatus wherein the coating material is maintained in an enclosed environment during the coating process.
- any coating apparatus must perform the functions of application, distribution, and metering. Each of these functions presents special problems. Inventors in this field have generally devoted their attention toward the individual solution of those problems. As a result the present art includes numerous knives, airknives, blades, aprons, and bars for accurately metering the surface flow of a coating fluid which has previously been applied and distributed. Application devices include pans, rolls, sprayers, and extruders. Distribution is performed in many Ways, often in combination with the application or meterings steps. In general, machines which perform all three functions well are large, complex, and expensive combinations of well known components. In the usual case these machines are limited, in practical application, to a narrow class of coating materials.
- My invention is a coating method and a compact, mechanically simple, and inexpensive coating apparatus adapted to apply, distribute, and meter coating fluid in a single combined operation without exposure to the air and with provision for removal of excess coating material from the coating area.
- the apparatus has as its main structure a large tubular member over which is drawn the uncoated web. This tubular member remains stationary dullng the coating operation.
- My apparatus includes also a longitudinal fluid-metering means positioned adjacent and parallel to the main tubular member; the intersection of the parallel members forming a longitudinal fluid holdmg cavity.
- the main tubular member is provided with one or more fluid admission apertures and one or more fluid discharge apertures. The admission apertures are so located as to provide a continuous supply of coating to the fluid holding cavity.
- the discharge apertures are so located as to be enclosed by the web in its approach to the fluid holding cavity.
- the web When the web is drawn over the tubular member it completely encloses a supply of coating fluid which has been forced through the admission apertures and into the fluid-holding cavity. Hydrostatic pressure forces excess coating fluid out through the discharge apertures.
- This arrangement of web and coating structure serves to isolate the coating fluid from the atmosphere. Furthermore, when the web is rapidly drawn across the relatively small coating region, the duration of the actual coating operation, or coating dwell time, is much reduced over conventional coating methods.
- the reduced dwell time decreases soak-up of water into the web, thus eliminating the local viscosity increase which commonly causes defects such as film split marks in coatings applied at higher solids content.
- the shortened coating dwell time makes it possible to apply overprints that would normally dissolve the inks. Also, isolating the solvent base coating from the air reduces fire hazards.
- the main structure may be fabricated from pipe and flat metal plates.
- Another object of my invention is to provide a method of coating a moving web wherein the coating dwell time is very short in duration and wherein the coating material is isolated from the atmosphere before and during the coating operation.
- Another object of my invention is to provide a stationary coating apparatus capable of applying an excess of coating fluid to a moving web and removing the excess through surface apertures.
- Another object of my invention is to provide a coating apparatus adapted to apply, distribute, and meter coating fluid to a moving web with no exposure of the coating material to the atmosphere until after completion of the metreing.
- FIG. 1 is a diagrammatic drawing of a typical machine embodying my invention. For simplicity of illustration, the end plates which support the metering bar and prevent fluid seepage about the web edges have been omitted.
- FIG. 2 is an enlarged sectional elevation drawing of the coating area for a machine using my invention in the form shown in FIG. 1.
- FIG. 3 is an enlarged sectional elevation drawing of the coating area for a machine using my invention in a different form.
- FIG. 4 is a sectional drawing of my coating apparatus in the preferred embodiment.
- FIG. 5 is a sectional drawing of an alternate configuration of my coating apparatus.
- FIG. 1 DESCRIPTION OF THE PREFERRED EMBODIMENTS
- the tubular member 11 may have any desired cross section, but, for manufacturing reasons, a circular cross-section is most desirable.
- Stand 18 rigidly supports member 11 so as to prevent any tendency to rotate with the moving web.
- a metering means in this case a wire wound rotating bar 12, is placed in a small groove which has been milled into member 11. The crest of bar 12 rises above the surface of member 11 so that when web 10 is wrapped around the combined structure there is formed an enclosed pocket 15 which is best illustrated in FIGURE 2.
- the numeral 13 represents any of a series of small apertures which have been drilled into the surface of member 11.
- Apertures 13 provide a passageway for coating fluid which is most desirably pumped into line 16 filling a supply cavity within member 11 and thence out through apertures 13 into the pocket 15.
- a series of discharge apertures 14 provide passages through which excess coating fluid flows into the interior of member 11 and thence out through line 19 to a recirculation system which is not illustrated.
- a motor 17 rotates bar 12 in a direction either following or opposing the movement of web 10.
- the machine shown in FIG. 1 would ordinarily be provided with end plates to reduce seepage of coating fluid around the edges of the web, but for purposes of clarity they are omitted from the illustration.
- FIGURE 2 illustrates in better detail the coating function itself.
- the rotating wire wound bar is completely wetted by coating fluid, but its rotation prevents the coating from running down the back side of member 11.
- the metering function is best performed when the wire wound bar is rotated at speeds between 20 and 40 r.p.m.
- a particularly novel feature of this :onfiguration is the location of the discharge apertures under the web in its approach path to the pocket 15. The web controls the return of excess fluid by restricting flow to the discharge apertures.
- Coating fluid should be supplied to the admission apertures at a pressure great enough to maintain a full coating pocket as well as a steady excess flow. However, this pressure must not be so great as to cause seepage of fluid around the edges of the web.
- Pressure relief may be achieved by throttling the supply, opening drain 27, or in many other obvious ways. Adjustments in internal fluid pressure may also be accomplished by altering the angle by which the web wraps member 11; particularly the wrap forward of discharge apertures 14 as designated in FIG. 2 by the angle on. I have found that a magnitude of about 60 degrees is most ideal for 0:. This wrap assures good contact, aids in preventing the formation of wrinkles, and seals the pocket [5. I have used this arrangement quite successfully in the :oating of hot melts.
- FIGURE 3 illustrates the coating function for an alternate configuration.
- the various elements are numbered to correspond with similar elements in FIG. 2.
- the illustrated apparatus differs from that of FIGURE 2 in that the arrangement of the surface apertures has been changed and the rotating metering bar has been replaced by a knife.
- the basic principle of the invention is present in both configurations. It will be apparent to one skilled in the art that many other variations may be employed. I do not intend to limit the scope of my invention by illustrating only 2 of the many possible configurations of the numbered elements. Furthermore, the use of the top of member 11 rather than the bottom or a side is not significant. My invention may be practiced in any desired vertical orientation.
- FIG. 4 The preferred structural arrangement is shown in detail in FIG. 4.
- Tubular member 11 has been cut away in sectioning fashion to expose a supply cavity 20 which has been formed by fastening plate 22 into member 11 with bolts 25.
- Coating fluid is forced into cavity 20- through an end plate aperture which is not illustrated but which is represented generally by 23.
- the coating fluid is forced through aperture 13 into pocket 15 where it is distributed and metered as previously described.
- the excess coating is forced down aperture 14 into discharge cavity 21 which is also formed in member 11 by plate 22.
- the excess coating continues out of cavity 21 through aperture 24 and thence into the recirculation system.
- a drain plug 27 is provided at the bottom of supply cavity 20.
- a guide roll 29 is mounted on an adjustable arm 34 to alter the wrap angle as above stated. Additional features which are illustrated in FIGURE 4 are a far end plate (near plate cut away) and a blade 26 for holding the web down in firm contact with the coating apparatus. Blade 26 is required in only a relatively few types of coating operations but it is shown for completeness of illustration.
- the tubular member 11 with its internal cavities and supply lines along with apertures 13 and 14 and the metering means 12 hereafter will be referred to as the coating head.
- FIG. 5 An alternate internal structure is illustrated in FIG. 5.
- the admission apertures 13 are replaced by a longitudinal slot (also denoted by 13 because of identity of function) which extends the entire length of member 11.
- a longitudinal weakening groove 32 also extends the entire length of member 11.
- a set of bolts 30' are fitted through openings in the wall of member 11 and threaded into plate 22. Washers 33 provide working surfaces between the wall of member 11 and the heads of bolts 30'. When bolts 30 are tightened down, the wall of member 11 is deflected longitudinally about the weakening groove 32 thus closing slot 13. In this manner the flow of coating fluid into pocket 15 may be accurately adjusted.
- Springs 31 may be provided if necessary for the reverse operation.
- the process which is inherent in the invention is not specifically illustrated in any single figure but is generally shown in all figures. It consists of wrapping a web over a tubular structure adapted to form an enclosed cavity between the web and the said tubular structure. Coating fluid is continually forced into the said cavity and metered by drawing or pulling the web across a metering device forming part of the back wall of the cavity. Excess coating is continually removed from the cavity; the entire operation being carried out in such a manner as to prevent exposure of the coating fluid to the atmosphere.
- An apparatus for coating an unstable fluid upon a continuously moving web comprising a stationary, tubular, web-supporting member provided at its surface with at least one fluid admission aperture and at least one fluid discharge aperture, and a fluid metering means oriented with its axis parallel to the axis of said web-supporting member; said web-supporting member and said fluid metering means by the juncture of their surfaces defining a longitudinal fluid-holding cavity, and said apertures for fluid admission and fluid discharge each providing non exposed passage between the longitudinal fluid holding cavity and the interior of the web-supporting member.
- a coating apparatus according to claim 1, said discharge apertures being arranged substantially along a first longitudinal line and said admission apertures being arranged substantially along a second longitudinal line, said second longitudinal line being located on the surface of said web-supporting member between said first longitudinal line and said metering means.
- a coating apparatus according to claim 2, the surface of said tubular member being shaped in the form of a continuously curved arch in the area between said longitudinal lines, and the placement of said first longitudinal line being sufficiently remote from said metering means that a plane extending between said first longitudinal line and the crest of the metering means will intersect the surface of said tubular member; the line of intersection being situated between the metering means and said first longitudinal line.
- said metering means comprising a rotatable bar.
- a coating apparatus according to claim 4 and further comprising a backing means for holding said web firmly against said rotatable bar.
- a coating apparatus according to claim 4 and further comprising a guide roll for adjusting the wrap angle of said web.
- a coating apparatus according to claim 1 said at least one fluid admission aperture being a longitudinal slot running the full length of said tubular member and said coating apparatus further comprising means for defleeting the wall of said tubular member thereby to alter the width of said slot and adjust the rate of coating fluid movement therethrough.
- a method of coating an unstable fluid upon a moving web comprising the steps of:
- a coating method according to claim 8 and further comprising the steps of continually recirculating said coating fluid from said discharge means to said surface cavity.
- a coating method according to claim 9, said coating fluid being thermally unstable and said method further comprising the step of preheating the coating fluid to a temperature near but above the fluid congealing point thereby promoting rapid post-application congealing for improvement of coating holdout.
