Definitions
- the invention relates to a device for coating material webs with a magnetic bar arranged on one side of the material web or a magnet roller preferably arranged at rest, by means of which a coating device arranged on the opposite side of the material web is pressed against the material web.
- a support body When using magnetic bars to generate the doctor pressure, a support body has been provided according to AT-A-289 158, which is continuous over the row of electromagnets of the magnetic bar and has a recess facing the doctor, which is covered by a sliding plate.
- the effect of the arrangement largely corresponds to an air knife, in which only the tensioned printing blanket counteracts the doctor blade pressure.
- the coating device on the side of the magnetic bar can either be a flexible metal sheet or plastic sheet in a known manner, which is supported on the magnetic bar, or a support on the magnetic bar, which runs at an acute angle to the point on the web at which the coating device attracted by the magnetic bar lies.
- FIGS. 2 to 7 show different variants for the application area essential to the invention with two co-operating coating devices
- FIGS. 10 and 11 show further variants of the design of the application area.
- Pig. 1 describes the invention in connection with a material web 3 running vertically upward, without however being restricted to such a spatial orientation.
- the web 3 runs over rollers 6, 6 'through a trough 7, which contains an application mass 10, and covers this mass on both sides.
- the order quantity and order depth or coating thickness are determined by the co-operating coating devices 2 and 4, between which the web 3 in Direction of arrow 11 is moved through.
- a magnetic bar 1 comprising a series of magnets is provided in a known manner and extends normally to the plane of the drawing, that is to say transversely to the web 3.
- This magnetic bar 1 exerts an attractive force on objects made of magnetizable material and can therefore be used in the simplest case for the immediate pressing of the stray element if, as shown in FIGS. 2, 4 and 5, they are designed as a solid body made of magnetizable material.
- the doctor blade blades 2 in a customary manner, particularly in the case of stencil printing, as a flexible metal strip and, as shown in FIGS.
- the invention provides for the support of the coating device 2 on the side of the magnetic bar 1 to be designed as a second coating device 4.
- This second coating device 4 can, as shown in FIGS. 1 and 2, be designed as an elastic metal sheet, which rests near its free end in a support bar 9 carried by the magnetic bar 1.
- FIGS. 2 to 5 show the left side of FIG. 3 in combination with the right side of FIG. 5
- FIG. 7 shows the left side of FIG. 4 also in combination with the right side of FIG. 5.
- the coating devices 2 and 4 simultaneously form the storage container for the coating composition to be applied to the web 3.
- the effective part of the coating device 2 is designed as a round bar.
- the guide rod 10 By rotating the guide rod 10 in the direction of the arrow, it is possible, with partial wear of the effective area of the coating device 2, to use a surface area which has not yet been used and which ensures the desired line contact on an exact straight line. Similarly, even wear of the surface could result from wear Round rod formed rounding of the coating device 2 can be achieved by slowly rotating this Strei chrunds tabes 2 compared to the speed of the web 3.
- Fig. 10 shows that coating devices 4 can have the shape of a resting round rod; However, it can also function device such as a scanning member String ⁇ whose surface moves relative to the web of the third
- the radius of curvature of the coating device 4 (here a cylindrical tube surrounding the magnet 1) can be relatively large, as long as it is ensured that in the angular region between the coating device 4 and the web 3 the application mass due to the sliding friction between these two Elements not only smoothed, but also stripped.
- the second coating device 4 provided according to the invention is pressed onto the web 3 in that the magnetic bar 1 exerts a force on the coating device 2, which is received by the second coating device 4.
- These forces are of course the same size, but this does not mean that the coating of the front and back of the web 3 must be chosen identically.
- the force which is of equal magnitude on both sides is distributed over differently large areas, so that a different pressure distribution can be generated.
