Definitions

  • the invention relates to a device for uniformly applying small or very small amounts of flowable media, including poorly flowable media, for. B. adhesives, and foamed media on a sheet-like carrier with the help of an application roller, wherein a pressure surface forming a magnetic bar or a magnetic roller is provided for pressing the carrier to the freely movable, magnetizable material application roller and each application roller a device for uniform distribution is assigned to the medium to be applied and the application roller has a diameter which is substantially smaller than. of an existing magnetic roller moves in the direction of movement of the carrier and always clamps the carrier between itself and the counter surface.
  • GB-A-1 472 426 shows a device according to the preamble of claim 1.
  • the application roller is stationary and there is a separate roller made of magnetizable material which can be moved against the application roller and thus presses the carrier onto the application roller. Between the individual pressing processes, the web is guided freely between the application roller and the roll made of magnetizable material.
  • a feed roller preferably made of magnetizable material, rests on the application roller, which is freely movable perpendicular to the surface of the medium located in a container, the conveyor roller or the application roller optionally having a porous or structured surface.
  • the application medium is first applied uniformly to an application roller by means of the conveying roller and is only transported from this to the application area on the sheet-like carrier, even small or very small amounts of application medium can be applied uniformly.
  • a conveyor roller is provided and this is freely movable in the substance ensures that the conveyor roller is always pressed against the application roller with the same force by the buoyancy force and possibly the magnetic attraction force and consequently the transfer of the medium to be applied is also uniform .
  • the applicator roller can avoid seams or other disturbances, so that these do not cause any disturbance during application.
  • FIG. 1 shows an embodiment of the invention in which two rollers of approximately the same diameter are provided.
  • Fig. 2 shows another embodiment, wherein a conveyor roller with a larger diameter and an application roller with a smaller diameter are present.
  • Fig. 3 shows another embodiment also with two rollers.
  • Fig. 4 shows schematically the arrangement of a container on a table. 5 is a detail of FIG. 4.
  • a web 1 is moved in the direction of arrow 2 continuously or in sections.
  • this web 1 is moved along the circumference of a roller 3, which is provided with one or more electromagnetic units 4.
  • a table with a magnetic bar can of course also be provided.
  • the magnet unit 4 is opposite an application roller 5 made of a magnetizable material, which in turn is in engagement with a conveyor roller 6.
  • Both the application roller 5 and the conveyor roller 6 lie in a space 7 which is partially filled with the medium 8 to be applied.
  • this medium is introduced into a channel-shaped container 10 via a width distribution device 9, at the lower end of which it is introduced into space 7 via a slot 11 above the floor. Due to the buoyancy of the medium, the conveyor roller 6 is pressed against the one wall of the space 7, which in turn presses the application roller 5 against a wiping brush 12 and against the web 1. In addition, the application roller 5 is pressed against the web 1 by magnetic force. In addition to the buoyancy force, an attraction force of the magnet unit 4 acts on the conveyor roller 6.
  • FIG. 2 shows an embodiment in which, as in FIG. 1, a magnet unit 4, an application roller 5 and a conveyor roller 6 are provided.
  • the conveyor roller 6 has a much larger diameter here and is designed as a hollow roller. You can e.g. B. consist of steel and have a rubber coating.
  • the conveyor roller 6 is only vertically movable in a holder 13 and is arranged here in a container or trough 14, the walls of which are partially parallel to the circumference of the conveyor roller 6.
  • the medium to be applied is again supplied here via a width distribution device, but directly into the container 14.
  • the conveyor roller 6 is immersed in the medium 8, which is located in a container 15.
  • the surface of the conveyor roller 6 takes a precisely metered amount of the medium 8 with its rotation and releases the medium at the point of contact between the conveyor roller 6 and the application roller 5 to the surface of the application roller 3, which in turn brings the medium to be applied to the web 1.
  • the conveyor roller 6 is arranged floating in the medium 8 and both rollers 5 and 6 are not axially supported, but can move freely in the vertical direction.
  • both the application roller 5 and the conveyor roller 6 are made of magnetizable material.
  • the application roller 5 should have a much smaller diameter than the conveyor roller 6.
  • the diameter of the application roller 5 is preferably between 15 and 20 mm. If both rollers 5 and 6 are made of magnetizable material, then surprisingly both rollers receive a force component for the magnet unit 4 and the application roller 5 is well pressed against the web 1 or the conveyor roller 6 against the application roller 5.
  • the amount applied can be adjusted very finely and precisely. It is possible to apply small and very small amounts of a substance, e.g. B. 5 to 50 g / m 2 of a sheet-like carrier without irregularities occurring on the web.
  • the method for applying small and very small amounts of flowable media to a sheet-like support can be improved further in that the amount of the media to be applied per unit area is applied not in one step but in several stages.
  • a plurality of devices according to the invention are connected in series or else the web is passed through a specific device according to the invention.
  • a plurality of magnet units 4 are provided in the magnetic roller 3 at angles to one another, each of which is assigned a specific device according to the invention.
  • a container or trough 10 is therefore detachably arranged on a table 43 via a fastening device 42.
  • the distance of the table 43 is adjustable according to the arrow 45 to the support surface 3, which is a counter roller in the present case.
  • the conveyor roller 6 lies on the wall 47 of the trough and the application roller 5 bears on the opposite wall 46 of the trough.
  • the conveyor roller 6 brings the medium to the application roller 5, from where the medium is brought to the web 1 and deposited there. In order to remove any remaining residues on the application roller 5, a scraper can be present on the wall 46.
  • the surfaces of the rollers 5 and 6 can be profiled in order to precisely dose the liquid to be applied.
  • One of these two rollers, but also both of them, can consist of magnetizable material and can be pressed against the web by the magnet 4 in the roller 3.
  • the trough 10 can be provided with an overflow 54, from which excess medium 8 is brought into a channel 53, which is attached to the table 43.
  • the trough 10 is releasably attached to the table 43 via a fastening device 42.
  • the fastening device has a lever 49 with a pivot pin 50, which has a wedge surface 52 at its lower end, which engages in an undercut 51 of a block 48 of the table 43.
