Definitions
- the invention relates to a device for applying a liquid or pasty application medium on a moving surface, for example a material web made of paper, cardboard or cardboard or a Applicator roller, comprising a stowage chamber which is on the underground inlet side of a storage chamber inlet limiting element and on the underground outlet side is limited by a storage chamber outlet limiting element, and a feed device for feeding the application medium.
- a device for applying a liquid or pasty application medium on a moving surface for example a material web made of paper, cardboard or cardboard or a Applicator roller, comprising a stowage chamber which is on the underground inlet side of a storage chamber inlet limiting element and on the underground outlet side is limited by a storage chamber outlet limiting element, and a feed device for feeding the application medium.
- Such application devices are, for example, in the prior art known as the short-dwell applicators which the application medium directly into an order or storage chamber is initiated, which is on the outlet outlet side of a doctor blade or a squeegee bounded by a stowage plate on the underground inlet side or another doctor blade is completed.
- Shortdwell applicators there are various problems that the Achieve an even layer application on the moving past At least complicate the underground.
- the squeegee has to be used to achieve an even layer application also be "rinsed" evenly. That means the pressure of the inflowing Application medium must be so even across the entire width of the order the squeegee are exercised that this to form an order gap of desired thickness of the passing substrate sufficient is lifted off evenly.
- the known application devices there is no one in the order chamber directly in front of the squeegee sufficiently uniform pressure, so that usually with a relative high pre-metered amount must be worked, otherwise in some places
- the application width of the squeegee is not the minimum coverage required Can guarantee the substrate with the application medium.
- the even application of layers to the substrate by air bubbles hindered past the storage chamber inlet limiting element in the Stowage chamber can get.
- a generic application device is known from EP 0 319 503 B1, in which in the baffle chamber inlet delimiting element formed by a doctor blade Passages are provided through which in the Excess medium introduced into the storage chamber against the Direction of the underground can emerge from the storage chamber.
- the leaked Application medium collects in front of the storage chamber in the area between the subsurface and the storage chamber inlet limiting element where as a "seal" it prevents the entry of air bubbles.
- the object of the present invention is an application device of the generic type to indicate with which at the same time A more uniform reduction in the required amount of pre-dosing Layer job can be achieved.
- the storage chamber inlet limiting element a throttling point, which is the entrance of application medium in the storage chamber in a desired and controllable Dimensions hindered. Due to this throttling effect, it already comes in the application medium accumulating in front of the storage chamber for an equalization in the transverse direction, i.e. to an equalization over the Order width. As a result, the one already entering the storage chamber points Application medium on an even pressure distribution, and it there is a further equalization of the distribution in the storage chamber and the pressure profile of the application medium in the transverse direction.
- the application medium is thus at the application device according to the invention over the entire width of the order at the storage chamber outlet limiting element, for example a doctor element, with essentially the same pressure, so that the latter according to the invention in high Dimensions are "flushed" evenly and ultimately become even Layer application can be achieved on the substrate.
- the arrangement according to the invention is sufficient in Comparison to generic devices of the prior art lower pre-metering quantity to achieve the desired layer application out.
- Another advantage of the application device according to the invention is to be seen in the fact that as a result of the possibility of having a smaller excess to work on order medium, the acquisition and operating costs of Let application device according to the invention keep low. The for Circulation of excess pump medium required pump power can be kept small.
- the above-described effect of the application device according to the invention can be further improved by the fact that the storage chamber entry limiting element or / and an underground inlet side and Storage chamber wall connecting the outlet outlet side of the storage chamber with regard to an equalization of the application medium is formed in the transverse direction.
