- the devices for driving the web are not shown and can be designed in a known manner.
- air supply ducts in the form of so-called nozzle boxes 9 are arranged at a distance in the longitudinal direction of the web, so that 9 spaces 3 remain between the nozzle boxes as air discharge paths, which also include the interior of unit 1, which is otherwise closed off by walls 4, is connected.
- the nozzle boxes 9 of the upper unit 1 are each to the nozzle boxes 9 of the lower unit 2 in this embodiment . offset by half a division, such that a nozzle area D on an upper nozzle box 9 is opposite an intermediate space between two lower nozzle boxes 9 and vice versa. Depending on the requirements and circumstances of the individual case, the arrangement can also be made differently.

- guide element 16 which extends as far as these and has passage openings 17 opening into the air discharge paths 3.
- Air of the desired temperature and the desired pressure passes through an inlet 5 in the direction of the arrow F1 into a distributor housing 6 located inside the unit 1 and from this into a branch housing 7, each of which is connected to the nozzle boxes 9 through openings (not shown).
- the air flowing out of the nozzle areas D passes through the openings in the guide elements 16 into the air discharge paths 3 and from there into the interior of the already mentioned Unit 1, from which it exits through an outlet 8.
- Corresponding devices for supplying and discharging the air to and from the unit 1 can be implemented in a known manner.
- the arrow F2 indicates the exhaust air flow.
- the same precautions are taken for the air flow as in unit 1. However, it is also possible to provide the arrangement described on only one side.
- FIGS. 2 and 3 show an embodiment of the device on a larger scale.
- guide elements 16 are provided, which have essentially the same length as the nozzle boxes 9 and, like these, extend transversely to the web running direction. Their edges abut the side walls 9a of the nozzle boxes 9 and are connected to them. This can be done in a suitable manner depending on the material used.
- the guide elements 16 expediently consist of sheet metal, just like the nozzle boxes 9.
- the joints or transition points are identified by the number 18.
- Each guide element 16 has a closed central region 16a. Laterally from this in the air discharge path 3 opening openings 17 are provided. These are expediently arranged in rows which are offset from one another.
- the central closed area 16a of the guide element 16 is advantageously flat. It may also be slightly curved.
- This central region 16a is followed by inclined portions 16b, in which the through openings 17 are also located in this embodiment.
- the inclined parts merge into edge regions 16c, which can run parallel to the central region 16a and extend to the junctions 18 with the side walls 9a of the nozzle boxes 9.
- the side walls of the nozzle boxes 9 project with lateral surface areas 19 over the guide elements 16 or over the connection point with the edge parts 16c of the guide elements 16 in the direction of a longitudinal plane E through the path of the web.
- the angle ⁇ at which the outer sides of the lateral projecting surface areas 19 are in relation to the longitudinal plane E is approximately 90 degrees.
- the formation of the nozzle areas D on the nozzle boxes 9 is possible in various ways.
- the advantageous embodiment shown in FIGS. 2 and 6 is explained in more detail below.
- the air flows emerging from the nozzle areas run as indicated by arrows in FIG. 2. They follow the end surface areas of the nozzle boxes 9 according to the principle of the Coanda effect and take the course also indicated by arrows on the guide elements 16 until the air is discharged through the openings 17 into the areas 3.
- the web B is advantageously guided continuously, whereby it is given a wave-like movement, as can be seen from FIG. 2.
- FIGS. 5 to 7. A further, very advantageous embodiment is shown in FIGS. 5 to 7.
- the same or corresponding parts are provided with the same reference numerals as in Figures 2 to 4.
- the front lateral surface areas 29 of the nozzle box 9 are each formed in the sense of an undercut.
- the angle ⁇ between such a surface area 20 and the longitudinal plane E is greater than 90 degrees, ie an obtuse angle.
- the guide elements 16 can be connected at points 18 to the side walls 9a of the nozzle boxes 9. However, as shown in FIG. 6, they can also continue in folded areas 28 which are at the same angle as the surface areas 29 and rest against the latter or be firmly connected to them in a suitable manner. The outer sides of the areas 28 then virtually take the place of the outer sides of the areas 29. A pronounced edge is also designated here by the number 20.
- FIGS. 8 to 10 An advantageous embodiment of the nozzle area D is illustrated in FIGS. 8 to 10, even with some modifications.
- a wall 10 belonging to the delimitation of an air supply duct 9 is shaped in such a way that wall areas which are at an acute angle to each other merge into a curved section 12 to which flat sections 13 adjoin. These parts 12 and 13 can be addressed as a guide surface L for an air flow.
- the wall areas 10 are provided with air outlets in the form of punched holes 14, the outlets on the one side being offset from one another on the other side in the longitudinal direction of the nozzle area D, that is to say transversely to the web direction, as is particularly the case in FIG. 10 reveals.
- Those facing each other Areas of the walls 10 form baffles 11.
- the air streams emerging from the holes 14 on one side strike the opposite baffle 11 and vice versa.
- the flow is then guided along the curved area 12 and the adjoining area 13. This is indicated schematically in FIG. 2 by the line S for one side.
- the baffle surfaces 11 are each inclined by the same angle a with respect to a transverse plane V perpendicular to the longitudinal plane E through the path of the path B, as can be seen from FIG. 9.
- FIG. 9 illustrates this on a dash-dotted impact surface 11 ', which has a greater inclination than the other impact surface 11 with the angle b.
- the inclination expediently lies in the range from approximately 10 degrees to 40 degrees. Angles of around 15 degrees are particularly favorable.
- all parts are formed by a coherent wall 10, which is bent accordingly in the lower apex area.
- the baffle surfaces 11 can also be formed by separate wall parts 10 'which are brought together at the ends and are tightly connected to one another by spot welding or in some other suitable way.
- a nozzle area of the type described is expediently located approximately in the middle of a nozzle box 9, as can be seen in FIG. 1.
- Another possibility is to provide only one baffle 11 on the nozzle area, which is then arranged with corresponding outlets.
- the design is then, for example, such that in the wall section 10 forming the right baffle 11 in FIG. 8 there are no outlets 14, but rather only in the wall section 10 on the left in FIG. 8.
- On this side there may also be no need for a guide surface L, but it can be attached to the wall section 10 e.g. connect an angled wall extension 15 as the normal boundary of a feed channel, as is indicated in FIG. 8 by dash-dotted lines.
- the outlet diameter d of the outlets can be specified as advantageous values for the outlet diameter d of the outlets.
- the distances e of the outlets can in particular be in the range from approximately 10 to 30 mm.
- the radius R of the curved portion 12 adjoining an impact surface 11 can advantageously be selected in the range from approximately 5 to 25 mm. Depending on the circumstances, other values are also possible.
- An embodiment is shown in FIG. 11, in which an end body 21 is located at the bottom of the nozzle region D. This extends over the entire width of the air duct 9 and has guide surfaces 22 on its side facing the plane of movement of the web B, which run roof-shaped in this embodiment. In the immediate vicinity of these guide surfaces 22, which delimit the end body 21, 23 air outlets in the form of bores 14 are provided in curved wall parts. The air streams emerging from these each go along the associated guide surface 22 and then meet the curved wall surface 23, where, similarly to the embodiment according to FIG. 8, the Coanda effect takes effect, so that the air around this wall surface and along the adjoining flat wall surface 13 flows and thereby acts on the web B and guides it in suspension.
- the end body 21 is advantageously designed as a ready-to-install and selectable unit.
- it can have the shape of a drawn metal profile, for example.
- a closure body of this type or a similar design can simply be inserted between two wall parts 24 of the air duct 9, these wall parts fitting tightly against the closure body.
- the end body can be fastened, for example, by means of screws 26, which are only indicated with their center lines in FIG. 11 and which penetrate holes in flange parts 25 of the air duct 9 and in flange parts 27 of the end body 21.
- FIG. 12 shows a closure body 31 which, like the closure body 21 in the embodiment according to FIG. 11, is attached to the base of the nozzle region D. and which on opposite sides of a part 33 projecting in the area of the transverse plane V in the direction of the movement plane E of the web has guide surfaces 32.
- Outlets 14 for the air in the immediate vicinity of the beginning of the guide surfaces 32 are also provided in wall parts 23 here.
- the air streams emerging from them are guided through the guide surfaces 32 so that they each run essentially perpendicular to the plane of motion E in the sense of an impact jet.
- the protruding part 33 of the closure body 31 can also lie outside the Qu plane V, and it can in particular also be at an angle to the transverse plane.
- the two guide surfaces 32 can also each have different positions or inclinations. The same applies to the guide surfaces 22 in the embodiment according to FIG. 11.
- the air outlets 17 in the nozzle areas or in the associated wall parts can not only have the shape of holes, but can also be designed like a nozzle itself.
- Such nozzle-like outlets are preferably produced from the material of a wall by a pressing or printing process. This allows the air jet to be given a desired direction.
- an embodiment of the aforementioned type is also present in those end regions of the nozzle boxes D which are normally outside the area occupied by the web. This not only results in a favorable lateral closing effect, but also has advantages in terms of the stability of the web movement.
- the passage openings 17 opening into the air discharge paths 3 are provided in inclined parts 16b of the guide elements 16.
- Such passages "are in another very favorable Auslanderun to 17 in the edge parts 16c, so close to the nozzle boxes 9.
- the guide elements 16 have a closed central region 16a.
- the transition to edge parts not only the shape of an inclined surface but there may also be an approximately arcuate or circular cross section at this point.
- the guide elements 16 may also be completely flat.
- the closed central area 16a is of essential importance because pressure builds up here and the web is thus held and guided perfectly at this point.
- the central region 16a of each guide element 16 is opposite a nozzle region D of a nozzle box 9. This means that there is a negative pressure zone at this point opposite the pressure zone on the other side of the web.
- zones by alternating Unterbuch ⁇ and 'pressure zones in the longitudinal direction of the web reaches a high stability of the web guide. This also applies in Transverse direction of the web, so that the web travel path is maintained perfectly and lateral migration of the web is prevented.
- nozzle areas of various designs within a system or treatment line e.g. on some of the treatment section, nozzle designs according to FIG. 11 and on another part, nozzle designs according to FIG. 1
