Description

The invention relates to an application head for applying liquid media such as liquefied thermoplastics or melted hot melt adhesives onto a material web that is relatively movable relative to the application head, with a housing, with a roller chamber in the housing, in which a roller slide can be driven in rotation is stored, with at least one feed opening for introducing medium into the roller chamber and with a slot nozzle for dispensing medium, which from Roller slide is controllable and is transverse to the direction of movement of the material web extends. The application head can in particular be contactless with the material web be arranged.

An application head of the type mentioned above is known from DE 197 14 029 C2. There, a roller valve is used, in an axial area in which the feed opening is a recess running over the entire circumference Has. At least in this axial area, none can be controlled by the roller slide Outlet nozzle opening. This means that the outlet nozzle openings in this axial region keep an undesirably large distance. The Roller valve is relatively short. With a longer length it would be necessary to provide a plurality of feed openings so that the above The problem occurred several times along the nozzle in the appropriate number.

Another application head of this type is known from DE 197 57 238 C2. in this connection are the surface grooves by axially parallel grooves on the roller valve or by mutually parallel helical grooves on the roller valve educated. With both versions, an economical application of liquid Medium can be achieved in an extremely even distribution on the material web.

Application heads of the type mentioned above are used in a variety of applications always used where material webs are laminated onto a substrate should be. To keep the specific consumption of liquid medium low maintaining and at the same time ensuring an extremely even distribution of the medium, an intermittent job is applied to a job image in raster form display. To ensure a high transport speed of the material web To enable, the order must be high in the direction of movement of the material web Frequency take place, the grid points transverse to the direction of movement of the material web should sit as close together as possible.

The present invention has for its object an application head of the aforementioned Provide way with which the consumption of liquid medium for special Use cases can be freely designed and / or further reduced.

The solution to this is that the order header has the following features:

  • a series of feed bores are made in the housing from the roller chamber to the nozzle,
  • the nozzle forms a multiplicity of individual outlet openings, each of which communicates with one of the feed bores in the housing,
  • the roller valve has a cylinder surface that can seal the feed holes to the nozzle from the inside,
  • the roller valve has at least one surface groove in the cylinder surface, to which liquid medium can be supplied and which, depending on the rotational position, can communicate with the supply bores to the nozzle and
  • the at least one surface groove is figurative or ornamental. The term figurative or ornamental surface grooves means that these surface grooves have boundary edges with a variable slope to the circumferential direction, or that the position of the boundary edges along the slide axis changes non-uniformly in the circumferential direction. This does not mean linear surface grooves of constant width.

In this way it is possible to depart from an even order and to produce special figurative or ornamental application patterns. This can be done be justified that the material web to be laminated onto a substrate later is heavier in some places than in others and therefore in the former individual points must be attached more strongly. This can also be because lie that the material web later to be laminated onto a substrate Has waste parts for which a previous application of medium is superfluous. As An example of this can be the production of panty liners from multi-layer material gluing along the circumferential edge.

According to a first embodiment it is provided that the surface grooves have a A plurality of circumferential grooves closed in the cylinder surface with variable Width. According to a second preferred embodiment provided that the surface grooves comprise at least one groove that is being developed a closed curve, e.g. B. forms a circle. After a third preferred Embodiment is provided that the surface grooves at least one in the cylinder surface over a limited circumferential groove with variable Width.

According to a further embodiment, it is proposed that the roller slide an internal cavity, to which liquid medium can be fed, and radial ones Exit bores that lead from the inner cavity to the surface grooves, includes. The surface grooves are supplied from the inside of the Roller slide. According to an alternative embodiment, it is proposed that that the roller valve fed at least one circumferential groove, the liquid medium can be, as well as connecting grooves from the circumferential groove to at least lead a surface groove includes. This is used to supply the Surface grooves over the surface of the roller valve.

An application head according to the invention is furthermore preferably characterized by this from that the nozzle is designed as a slot nozzle and is equipped with an orifice that forms the plurality of outlet openings along the slot nozzle. Here in particular proposed that the aperture is formed by a comb plate, which in the slot nozzle is inserted and comprises a plurality of tines between which the plurality of outlet openings is formed.

In order to continuously supply medium to the inside of the roller valve, provision can be made be that the roller slide at least one axially emerging from the housing Has pin in which an axial bore is made, which with the inner Cavity is connected and serves to supply liquid medium. A another possibility for this is that at least one end of the housing a nozzle is provided in the housing and an annular channel between the roller valve and roller chamber is formed, which is connected to the nozzle in the housing is, and that radial feed bores in the roller valve in the plane of Ring channel are executed, which are connected to the inner cavity and the Serve supply of liquid medium.

The ring channel mentioned can be through an annular groove in the roller chamber surface be formed. The annular channel is preferably formed by a circumferential groove in the surface of the roller slide formed with the feed nozzle in the housing communicates. The further guidance of the medium can also be carried out transversely Connection grooves on the surface of the roller valve at least a surface groove according to the invention take place. Here, the nozzle would Transverse direction does not extend beyond the extent of the at least one surface groove. According to the preferred embodiment, however, it is provided that the medium from the ring groove into the inner cavity and from there back into the surface groove is carried out as already described in detail above.

From the surface grooves according to the invention, the medium passes along the Radial holes arranged in the housing. Depending on the change in the edge course of the surface grooves in the circumferential direction when the roller slide rotates more or less or other radial bores, so that the Spray veil at the nozzle narrowed or spread or extended. The representation of individual threads transverse to the direction of movement of the material web can be used a corresponding aperture with outlet openings at a short distance from each other generated in a slot nozzle. In this case, preferably one radial bore each in the housing are connected to an outlet opening in the panel.

Preferred embodiments of the invention are described below with reference to the Drawings explained.
