Description

The invention relates to an application head for contactless Application of liquid media such as liquefied thermoplastic plastics or melted hot melt adhesives a material web relatively movable to the application head, with a Housing, with a roller chamber in the housing, in which a rolling slide is rotatably driven, with at least one Feed opening for the introduction of medium into the roller chamber and with a slot nozzle for the discharge of medium from the rolling is controllable and is transverse to the direction of movement Material web extends.

An application head of the type mentioned above is from the DE 197 14 029 A1 known. There is a roller valve used the one in an axial area in which the feed opening lies has recess running over the entire circumference. At least in this axial area none can be controlled by the roller valve Outlet nozzle opening. This means that in this Axi albereich the outlet nozzle openings an undesirably large Must keep a distance. The roller valve is otherwise relatively short. With a longer length it would be necessary to use a Provide a plurality of feed openings so that the above described problem along the slot nozzle in a corresponding Number of appearances.

Application heads of the type mentioned above are available in diverse applications wherever material is used  to be laminated onto a substrate. To the keep specific consumption of liquid medium low and at the same time an extremely even distribution of the medium si an intermittent order is applied to to display an order image in raster form. To do this to enable high transport speed of the material web, the order must be high in the direction of movement of the material web Frequency occur, the grid points transverse to the movement the direction of the material web as close as possible to each other should.

From EP 0 474 155 A2 and from EP 0 367 985 A2 are up known carrying heads, in which perforated nozzles by means of a pneuma table operated nozzle needle can be controlled. At high speed the speeds of achieving an economical failure assigned order of medium at the limited maximum Clock frequency of the nozzle units due to the inertia the nozzle needles and the controls are limited.

Proceeding from this, the object of the invention is to provide an application head of the type described above, which produce an extremely dense application pattern even with long lengths can.

The solution to this is that the roller valve has the following features:

  • - An inner cavity, the medium through the feed opening can be fed
  • - A cylinder surface that seals the slot nozzle from the inside can,
  • - Surface grooves in the cylinder surface, the rotary position can communicate depending on the slot nozzle, and
  • - radial outlet bores from the inner cavity to the Surface grooves.

An application head according to the invention has the advantage that the Control of the medium takes place directly at the slot nozzle det, so the accuracy of the metering is not affected by the toughness speed of the medium or the elasticity of the medium behind the Control point can be adversely affected. Through the Supply of the slit nozzle with medium from inside the whale zenschieberers can exit openings over the entire The length of the roller valve without any technical disturbances possible distance can be arranged. By choosing the shape The surface grooves can have different grids and patterns in the Media order are shown.

In a first favorable embodiment it is provided that the Surface grooves include a plurality of axially parallel grooves sen. If a uniform grid of points is to be generated, it is advantageous to have a plurality of axially parallel surfaces grooves at a uniform circumferential distance on the surface of the Roll slide to provide. The spacing of the grid points in Direction of movement of the material web can be changed by changing the Rotation speed of the roller slide can be influenced. If the surface grooves are at an uneven distance above the Circumference of the roller valve can be distributed at a constant Drive speed generated a non-uniform grid of points become. On the other hand, with a uniform circumferential distance axially parallel surface grooves a non-uniform grid of points due to variable drive speed of the roller valve be achieved. Known servomotors for control are closed capable of such uneven driving speed.

The display of raster points across the direction of movement of the Material web can be used by using an appropriate nozzle screen with individual holes at a short distance in the slot nozzle be generated. If the use of such a nozzle orifice is waived, arises when using axially parallel ones Grooves a line application in each case transverse to the direction of movement of the  In a second advantageous embodiment, the surfaces grooves include at least one helical or helical groove. This creates opening areas on the slot nozzle, which when driving the roller slide in one direction along the Slit nozzle move so that while moving the Material web diagonally across the material web wearing pictures arise. This embodiment is preferred wise slot nozzles used without nozzle orifices, so that the mentioned diagonal orders in the form of threads on the materi albahn be launched. It can be convenient here, two successive application heads with opposite ridges of the surface grooves with the same drive direction or with opposite drive direction at the same slope use so that a pattern of symmetrically intersecting diagona threads of the medium are generated on the material web.

In a first embodiment, the roller valve is at least with provided an axially emerging from the housing in the an axial bore is made with the inner cavity is connected and serves as a feed opening. Hereby the Housing design particularly simple, but one must rotate de Seal in the area of the pressurized medium supply be provided. In an alternative version, on is too At least one end of the housing has a hole in the housing seen and an annular channel between roller valve and roller came mer trained, which is connected to the bore in the housing and there are radial feed bores in the roller valve in the Level of the ring channel that runs with the inner cavity are connected and serve as a feed opening. This allows the Slider storage can be simplified. The supply of medium to the housing can be done via simple radial holes. Of the called ring channel can through an annular groove in the roller top surface and / or through a circumferential groove in the roller chamber bore be formed. The ring channel can also be in the end face area  of a roller valve placed on the pin, where the radial feed holes through axial feed holes in these end faces to be replaced. Regardless of the fact whether a feed at only one or both ends of the roller slide takes place, can compensate for a small pressure drop stes a correspondingly small in the medium over the slide length Increase in the diameter of the radial outlet bores to the Grooves are provided. An escape of medium from the housing can be prevented by using conventional shaft seals become.

Preferred embodiments of the invention are as follows explained using the drawings.
