Definitions

  • the coating machine employs a blade which has a chamber between the blade proper and the moving article to receive a pressurized supply of a flowable substance.
  • the blade is pressed perpendicularly towards the path of the moving article under a force which is opposed by the pressure of the flowable substance to cause the blade to float on a cusion of the flowable substance.
  • This force can be generated by directing the flowable substance into a thrust chamber on the far side of the blade while the chamber on the near side of the blade receives the substance at a lower pressure via restricted passageways. The difference in pressures provides the resultant thrust force.
  • This invention relates to a blade for applying a flowable substance to a moving article, particularly a travelling web on a roller surface.
  • the invention provides a blade for applying a flowable substance onto a moving article, such as a traveling web or a rotating roller, which has at least one chamber for containing the flowable substance disposed transversely of the direction of the moving article and facing the moving article.
  • a moving article such as a traveling web or a rotating roller
  • means are provided for pressing the blade towards the moving article under a force opposed to the pressure of the flowable substance in the chamber to cause the blade to float on a cushion of the flowable substance on the moving article.
  • the pressure of the applied coating composition is a parameter which can be used to provide direct control of pin size and thickness of application.
  • the quantity applied can be controlled very readily on a stepless variable basis. It is therefore a simple matter to arrange for remote control.
  • the blade can be positioned to engage by way of a large area with the flowable substance on the top of the article, so that the article is treated gently and the pressure of the coating composition acts on the article by way of a large contact zone.
  • the blade can be disposed anywhere on an article-guiding roller independently of gravity. Further, high-speed operation is possible, for in contrast to what happens with applicator rollers, there is no film splitting, i.e., there is no detachment from the article of some of the applied composition after application. Also, operation without a surplus or excess is possible. Thus, no doctor device is required and there is no need to circulate the coating composition.
  • the feed pumps for the coating composition can therefore be very small.
  • the chamber is of very reduced height in relation to the width.
  • all or some of the chamber can be in the form of discrete interconnected grooves.
  • those parts of the chamber which engage with the article can engage therewith by way of large areas.
  • the flowable material in order to produce the force for pressing the blade towards the moving article, is also directed to apply pressure to that side of the blade which is distal from the article. Consequently, the pressure of the flowable substance acts on the blade side near the article and on the blade side remote therefrom.
  • the blade is thus retained solely by pressures and, therefore, enters very readily into intimate engagement with the article and is therefore easy to control. Also, the blade is pressed evenly against the article over the whole width, thus obviating unwanted sag of the blade.
  • each chamber is connected by at least one line to the blade side distal from the article.
  • the line can be a passage in the blade, so that the flowable substance can be supplied through the blade to each chamber.
  • an adjustable restrictor can be disposed in each line.
  • the pressured blade surface distal from the article can be smaller than the oppositely pressured side of the chamber.
  • the blade is disposed on a support member to be slidable substantially perpendicularly to the article so as to cooperate with the support member to define at least one sealed thrust or bearing chamber which is supplied with the flowable substance or some other pressure medium.
  • the flowable substance can be supplied to each chamber via the blade side near the article or to the bearing chamber via a suitable line.
  • the chamber can be sub-divided into two longitudinal chambers by a ridge or web or the like which extends along the blade and which preferably engages with the article. The use of different pressures in these longitudinal chambers helps to improve tilting stability and reduce edge wear.
  • longitudinal edges of the blade which engage with the article can cooperate therewith by way of a gap whose size can be varied, and two coating compositions can be applied to the article simultaneously.
  • one coating agent can be applied via one longitudinal chamber and surplus agent can return through the other longitudinal chamber.
  • the ridge can be slidingly mounted in the blade, and the flowable substance or a controllable pressure agent can act on the ridge side distal from the article, so that the gap between the ridge and the article is controllable.
  • ridges or webs or the like which preferably engage with the article can sub-divide each chamber or longitudinal chamber. The stability with which the blade floats on the article can be improved by Supplying the flowable material to the chambers through separate lines.
  • this feature enables the gap height to be varied over the article width, i.e., the thickness of the application on the left-hand side of the article can be different from the thickness of the application on the right-hand side of the article.
  • the ridges can extend at an inclined angle relative to the blade longitudinal axis and can be so disposed that at the place where one ridge terminates, another ridge begins on the opposite side. This feature leads to a uniform stripe-free coating.
  • the support member is retained by hydraulic cylinders.
  • those parts or ridges of the chambers which engage with the article can be replaceable.
  • the bearing chamber can be sub-divided into two longitudinal thrust chambers by a longitudinal ridge or web or the like and each longitudinal thrust chamber can be connected via at least one line to the corresponding longitudinal chamber.
  • one longitudinal chamber can serve for the supply of flowable substance and the other longitudinal chamber can serve for the return of surplus substance.
  • the wall disposed on the runout side of the article can be a doctor device.
  • the blade can be rotatable around a longitudinal axis, thus giving very good engagement and accurate controllability.
  • the flowable material can be introduced into and removed from the chambers through lateral passages of the blade.
  • the blade is pressed against the article by a controlled pressure medium or a resilient medium or by its own weight.
  • the blade can be so flexible as to engage intimately with the article.
  • the moving article is in the nature of a traveling web or surplus surface
  • the article can be guided on a roller at the place where the blade engages with the web or the web can be guided on a similar second blade disposed opposite the first blade.
  • the second blade can be nondisplaceable, i.e., mounted in a fixed manner.
  • the chamber parts which engage with the moving article are rounded or nozzle-shaped on the side where the article first impinges.
  • the article is therefore treated gently and a speed-dependent hydrodynamic pressure increase is produced at the runout side and at central webs.
  • FIG. 1 illustrates a cross-sectional view through a blade with a longitudinal chamber and a bearing or thrust chamber according to the invention
  • FIG. 2 illustrates a cross-sectional view through a blade having two longitudinal chambers and a bearing or thrust chamber according to the invention
  • FIG. 3 illustrates a side view of a blade disposed on a roller according to the invention
  • FIG. 4 illustrates a cross-sectional view through a blade having two longitudinal chambers and two bearings or thrust chambers according to the invention
  • FIG. 5 illustrates a cross-sectional view through a blade adapted for rotation around a longitudinal axis and having two longitudinal chambers, one bearing or thrust chamber and a doctor device according to the invention
  • FIG. 6 illustrates a cross-sectional view through two contiguous blades according to the invention with a web of material passing through between them;
  • FIG. 7 illustrates a plan view of the longitudinal chambers of the blade of FIG. 2 with the roller removed.
  • the coating machine includes a plastics or metal blade 1 which engages, by way of a wear resistant layer, e.g. of plastics or ceramic, and/or by way of replaceable edges 2a, 2b on a web of material 12 guided by a roller 5.
  • the blade 1 has a flat chamber 4 on one side which extends over the whole width of the web 12 to receive a flowable substance, such as a coating composition of known type.
  • This chamber 4 can be of similar flatness to the flatness of the liquid bearing (i.e., flat) sources known in bearings and can therefore take the form simply of discrete interconnected grooves.
  • the web 12 cooperates with the blade 1 to define the boundaries of the chamber 4.
  • the blade 1 is mounted in a support member 9 for sliding perpendicularly to the web 12.
  • the support member 9 cooperates with the blade 1 to define a bearing or thrust space orchamber 11 which extends over the whole of the blade side distal from the web 12.
  • a sealing ridge or ledge 7 and a resilient cylindrical member 8, are mounted, as shown, between the blade 1 and support member to seal the thrust chamber 11.
  • the blade 1 can be ledge-like or ridge-like on the underside or can take the form of discrete short pistonlike elements which engage in discrete cyclinders formed by the support member 9, so that the chamber 1 l, as considered transversely of the web 12, comprises a number of component chambers.
  • the blade 1 is pressed against the web 12 either by a resilient element (not shown) or by its own weight or, as shown, by a pressure medium supplied to the thrust chamber 11 via an inlet 10.
  • the pressure medium can be in the flowable substance which is to be applied to the web 12 and which passes from the chamber 11 to the chamber 4 via a passage or line 6 formed in the blade 1.
  • the pressure of the flowable substance therefore acts on two opposite sides of the blade 1.
  • the blade 1 can be urged toward the roller 5 or web 12 at a predetermined pressure.
  • the pressure In operation, as a pressure builds up in the chamber 4, the pressure also acts against pressure in the thrust chamber 11 and causes the blade 1 to float on a cushion or film of the coating composition. Depending upon the amount of the coating composition pressure, a corresponding amount of coating composition flows through between the blade edges 2a, 2b and the web 12 and issues on the runout or delivery side as a correspondingly thick coating.
  • the coating thickness can, therefore, be controlled just by controlling the pressure of the coating composition.
  • an adjustable restrictor 3 in the line 6 can be used for control purposes. This restrictor 3 can be disposed inside or outside the blade 1 and can be adjustable either manually or automatically.
  • the gap 13a defined by the blade edge 2a and web 12 on the web entry side can be so adjusted that the drag force of the paper web 12 on the coating composition is exactly the same as the issue of composition through the gap 13a.
  • the two edges 2a, 2b can also vary in width to suit requirements, and very good adaptation of the blade 1 to the web 12 can be achieved if blades which are of very reduced height or made of a flexible material are used.
  • the blade 1 remains completely straight even though the support member 9 sags, since the constant liquid pressure in the chamber 11 ensures that the blade 1 is borne uniformly.
  • the support member 9 is mounted at the ends in two hydraulic cylinders 51, so that the support member 9 and blade 1 can be moved into and out of operative position very rapidly.
  • the roller 5 is supported at bearing points 52 by suitable bearings mounted in machine frame supports 50 while the hydraulic cylinders 51 are pivotally mounted at the ends in the support 50.
  • a rib or ridge 16 is disposed within the blade 1 to sub-divide the chamber 4 into two longitudinal chambers 4a, 4b.
  • Each of these chambers 4a, 4b is connected to the thrust chamber 11 by one passage 6a, 6b each and a respective adjustable restrictor 3a, 3b.
  • the two chambers 4a, 4b can be oper ated at different coatingcomposition pressures, a feature which helps to stabilize the blade 1, i.e., which reduces the tendency of the blade 1 to tilt.
  • the rib 16 bears against the web 12.
  • the thrust chamber 11 can also be subdivided into two longitudinal chambers 11a, llb which have one inlet or outlet passage a, 10b each and which are connected to the respective longitudinal chambers 4a, 4b above by way of passages 6a, 6b and adjustable restrictors 3a, 3b.
  • the blade 1 can therefore operate with two different coating compositions so that a single blade can apply two different coating compositions to the web 12, or alternatively, the composition is applied by the longitudinal chamber 4a on the web entry side and surplus composition is returned via the longitudinal chamber 4a on the web entry side and surplus composition is returned via the longitudinal chamber 4b on the web exit side.
  • the ridge 16 is mounted in the blade 1 for sliding perpendicularly to the web 12.
  • the bottom or back of the ridge 16 cooperates to bound a chamber 37 and is acted upon by a pressure medium, e.g. the coating composition, supplied through passages or lines 60, lOc.
  • the support member 9 has a ridge 27 which separates the two longitudinal chambers 11a, 1 lb from one another and extends into a corresponding recess 11c in the blade 1.
  • the recess 1 10 connects passage in the support member 9 to the passage 60 in the blade 1 and is of the same width as chamber 37, to ensure that the pressure medium which acts on the ridge 16 has no effect on the blade 1.
  • the blade 1 is sealingly mounted in the thrust chambers 11a, llb by similar sealing elements as above.
  • the coating composition can also be supplied via a passage 14 to the longitudinal chamber 4a on the web entry side, while surplus coating composition passages from the longitudinal chamber 40 on the web exit side through passage 6b into the thrust chamber 11, then through a discharge passage 10 which has a restrictor 30 back to a feed pump (not shown).
  • the passage 6b has a restrictor 3b, and a passage 6a which is parallel to passage 6b and which has a restrictor 3a extends from chamber 4a to chamber 11.
  • a doctor device 101 in the form of a blade is mounted in a holder 103 to define one side wall of the chamber 4b on the web exit side.
  • the blade 1 has a lateral inlet passage through which a pressure medium can be supplied to the chamber 37 to act on the ridge 16.
  • the blade 1 is mounted for rotation around its longitudinal axis, the underside of the blade 1 being convex and being received in a matching recess in the support member 9.
  • the recess in the support member serves as the thrust chamber 11.
  • the chamber 11 can receive a compression spring 92 to act on the blade 1 to apply further pressure, in addition to the pressure medium, on the blade 1 in a direction perpendicularly to and towards the web 12.
  • the blade 1a has two longitudinal chambers 4a, 4b and two longitudinal chambers 11a, 1 lb, the web being guided not by a roller but by a second blade 1b disposed opposite the first blade 1a.
  • the blade 1a differs from the blade shown in FIG. 4 in that in FIG. 6 the coating composition is supplied to the chambers 4a, 4b not via the chambers 11a, 1 lb but via side passages 31a, 31b having external restrictors 3a,
  • the blade lb is non-movably disposed instead of being mounted for sliding in a support member.
  • the coating composition is supplied to the chambers 40, 4d of the blade lb through distributing chambers 76, 82 an through passages which have restrictors 3c, 3d. With this arrangement, both sides of the web 12 can be coated simultaneously. In order to reduce stressing of the web 12, those parts of the chambers 40 to 4d which contact the web 12 have rounded comers 69 at the entry edges. A speed-dependent hydrodynamic pressure increase is also produced at the central ridge 16 and at the exit side during operation.
  • the chambers 4a, 4b, for example, of the blade 1 of FIG. 2 are subdivided into a number of sub-chambers by ridges or webs 18 extending in spinefashion.
  • This feature enables the thickness of the web coating to be varied transversely of the direction of web movement an important consideration, if the absorptivity of the web 12 varies over the web width, as may occur because of differences in production.
  • the ridges 18 are so disposed that wherever a ridge 18 starts at the edge 2a or 2b, another ridge 18 tenninates at the ridge 16 on the opposite side of the chamber.
  • the proportion of ridges 18 is therefore constant over the whole width of the web 12.
  • Two passages 60, 6b extend to each of the sub-chambers.
  • the blade has been described as applying a flowable substance to a web; however, the blade according to the invention can be used to coat a surface or roller with a flowable composition directly, such as eg a paint applicator roller or a drying roller, inter alia for the production of powdered milk.
