Description

Field of the invention

The invention relates to a dampening unit housing, a moistening device of a spray dampening unit for printing machines with such a dampening unit housing, and to a method for producing such a dampening unit housing.

Background of the invention and prior art

Dampening units are used in printing technology. As a rule, dampening systems are devices with a series of contacting rollers, which apply a dampening solution (usually water and several additives) evenly to a pressure plate.

Dampers can apply fountain solution via a water box, via nozzles or in a similar manner e.g. applied to a ductor roller and then conveyed as a water film over all rollers evenly to the pressure plate. The dampening units in which nozzles are used are also referred to as spray dampening units.

Sprühfeuchtwerke usually have a spray valves carrying spray bar, which is mounted for different purposes towards the roller and away from this adjustable on a housing.

A spray dampening of this kind is from the EP 1 009 633 B1 known. In the known device, the two ends of a spray bar are held such that the spray bar and thus the spray nozzles can be adjusted to the roller.

The patent DE 698 35 545 T2 describes a spray dampening unit, the spray bar is pivotally mounted on a fixed spray room. The spray dampening unit is divided into two components, a spray room permanently mounted on the pressure frame and a rear pivoting beam in which the spray valves are located.

The US 4,831,927 describes a humidifying apparatus comprising a spray bar having a plurality of spray nozzles. A pair of pivotable elongate spray bars limit the extent of the spray jet across the spray bar, and a pair of slidable spray plates limit the length of the spray jet in the longitudinal direction of the spray bar.

Further spray dampening units will be installed in DE 198 11 554 C1 and DE 103 17 470 B4 described.

In the known spray dampening designed the maintenance of the valves, the control of contamination in the spray room and the cleaning of the device z.T. difficult. The device of the spray dampening is complex and can z.T. be adapted only to a limited extent to the circumstances.

Conventional housings of dampening systems are usually made of several sheet metal parts. The sheet metal parts are bolted or welded together to make the housings of the dampening units. The production is designed z.T. as costly and expensive.

The invention is based on the object, a cheap to manufacture and stable dampening unit housing and an easy-to-maintain and / or to be converted moistening device of a dampening unit for printing presses with such To provide dampening unit housing and a method for producing such a dampening unit housing.

Solution of the task

The object is achieved by the devices and the methods according to the independent claims. Advantageous embodiments are disclosed in the subclaims.

• Bereitstellen eines aus einem Flachbauteil bereitgestellten Gehäuselängselements
• Bereitstellen zweier Seitenteile mit Nuten zur Aufnahme des Gehäuselängselements
• Einsetzen des Gehäuselängselements in die Nuten
• Abdichten des Gehäuselängselements in den Nuten

A first aspect relates to a method for producing a dampening unit housing comprising the steps:

• Providing a housing made of a flat part longitudinal housing element
• Providing two side parts with grooves for receiving the housing longitudinal element
• Insert the housing longitudinal element in the grooves
• Sealing the housing longitudinal element in the grooves

The term flat component denotes a raw material from which the housing longitudinal element is produced. A flat component may be a sheet metal part or a part with sheet-like geometry made of a non-metallic material. The dampening unit housing may have an elongated shape. The dampening unit housing can extend in the operating position of the dampening unit on a printing press substantially over the entire width of a cylinder to be cleaned of the printing press. The side parts are arranged on both sides of the dampening unit housing in the region of the axial ends of the dampening unit housing. The housing longitudinal member extends between these axial end portions of the dampening unit housing and defines an interior of the dampening unit housing. The housing longitudinal element can be produced in one piece or from a plurality of individual, separate flat components. The housing longitudinal element may have, for example, an upper housing longitudinal part and a lower housing longitudinal part. The interior of the dampening unit housing can be designed such that in the interior of a spray bar can be added. Furthermore, the dampening unit can delimit a spray chamber in the spray direction in front of the spray bar.

• Erzeugen von Kanten in dem Flachbauteil, wobei alle im Flachbauteil erzeugten Kanten im Wesentlichen parallel zueinander angeordnet sind.

Such a method may further comprise the step of:

• Generating edges in the flat component, wherein all edges produced in the flat component are arranged substantially parallel to each other.

The step of creating the edges can be done by folding, i. by forming, in particular by bending along a tool edge of a Abkantwerkzeugs. Such a method for producing a bending edge is particularly suitable when the flat component is a sheet metal part. The step of creating the edges may be such that no non-parallel bending edges are generated.

• Erzeugen der Seitenteile im Spritzgußverfahren.

Further, in such a method, the step of providing the side portions may further include the step of:

• Generating the side parts by injection molding.

The side panels can be made in one piece.

• Erzeugen der Nuten, welche in Bezug auf eine Materialstärke von korrespondierenden Endbereichen des Gehäuselängsteils derart bemessen sind, dass nach dem Einsetzen der Endbereiche in die Nuten eine feuchtmitteldichte Passung zwischen den Endbereichen und den Nuten bereit gestellt wird.

The step of providing the side parts may further comprise the step of:

• Producing the grooves, which are dimensioned with respect to a material thickness of corresponding end portions of the housing longitudinal part such that after insertion of the end portions in the grooves, a moisture-tight fit between the end portions and the grooves is provided.

The end portions of the housing longitudinal part in the sense, are the areas that are absorbed by the grooves when inserting the housing longitudinal element. In the step of creating edges in the flat member, the edges may be formed such that the edges are at least partially attached to the edges End areas are formed. Accordingly, the end portions may at least partially have the same cross-sectional profile, as the housing longitudinal element in the rest. Such a cross-sectional profile may have L-shaped and / or U-shaped cross-sectional profile areas. The grooves may have a cross-sectional shape corresponding to the cross-sectional profile of the end regions. It may be sufficient in the production step to provide the grooves with appropriate fit only in areas where a seal between the housing longitudinal element and the grooves is desired, for example in the bottom region of the dampening unit, in which dampening solution can collect during operation of the dampening unit. With such a configuration of the grooves, the step of sealing the housing or the longitudinal housing element in the grooves during and by inserting the housing longitudinal element in the grooves can be carried out. The step of generating the correspondingly dimensioned grooves can be done, for example, when producing the side parts by injection molding. It is also conceivable that the grooves are produced in the side part by machining or that grooves which have been provided on the side part by injection molding, are reworked in a further example, cutting process step such that they have the desired fit. Alternatively or in addition to the corresponding design of the grooves, sealing material can be inserted into the grooves in order to provide a seal in the joining area between the housing longitudinal element and the side parts in the finished dampening housing. Such sealing material can be provided, for example, in the form of a rubber lip and / or a liquid seal and / or silicone. The sealing material can be provided in the grooves before inserting the housing longitudinal element into the grooves or after inserting the housing longitudinal element.

• Fixieren der Flachbauteile in den Nuten insbesondere durch Verstiften und/oder Verschrauben und/oder Vernieten und/oder und/oder Verrasten und/oder Umformen der in die Nuten eingesetzten Endbereiche des Gehäuselängsteils.

Such a method may further comprise the step of:

• Fixing the flat components in the grooves in particular by pinning and / or screwing and / or riveting and / or and / or latching and / or reshaping of the end portions of the housing longitudinal part used in the grooves.

In this case, holes may be provided in the region of the side parts and / or at the end regions of the housing longitudinal part, into which holes are e.g. transverse to or perpendicular to the direction of insertion of the housing longitudinal part pins and / or screws and / or rivets are introduced, which prevent withdrawal of the housing longitudinal part of the grooves. The holes may e.g. be provided as blind holes. The diameter of the blind holes may be sized with respect to pins to be inserted so that a press fit is made between the pins and the hole. In such a pinning, the assembly of the dampening unit housing can be made such that the dampening unit housing can not be dismantled without destruction, which may be advantageous in terms of safety. Furthermore, locking lugs or other latching elements can be provided in the side parts and / or in the housing longitudinal part, which causes a fixation of the components when inserting the housing longitudinal part in the grooves. Fixing by forming can e.g. caused by e.g. in the region of the grooves, e.g. In the groove base, through holes are provided, which extend in the insertion direction through the side part. In the end regions of the housing longitudinal element tab-like extensions can be provided, which are inserted when inserted through the through holes. After insertion, the protruding part of the tab-like extensions can be bent.

• Bereitstellen gleicher Seitenteilpaare für Feuchtwerksgehäuse unterschiedlicher Breite;
• Bereitstellen von Flachbauteilen unterschiedlicher Breite für Feuchtwerksgehäuse unterschiedlicher Breite.

Such a method may serve to produce a series of dampening cabinets having different case widths and may further include the following steps:

• Provide same Seitenteilpaare for dampening unit housing different widths;
• Providing flat components of different widths for dampening unit housings of different widths.

Through this manufacturing process, the number of variants of the components for the different types of dampening units can be reduced. Furthermore, costs can be saved in mold design, if the side parts are produced for example by injection molding.

A second aspect relates to a dampening unit housing a spray dampening unit comprising a housing longitudinal member and two side parts, wherein the housing longitudinal member has an elongated shape with two end portions which are arranged in the longitudinal direction of the housing longitudinal member on opposite sides of the housing longitudinal member, wherein the side parts each have at least one groove, and wherein the end portions of the housing longitudinal elements are sealingly received in the grooves.

In such a dampener housing, the side parts injection molded parts may be in particular injection molded plastic parts. Furthermore, the housing longitudinal element may have a sheet metal part.

In such a dampener housing, the housing longitudinal element may have one or more housing longitudinal parts.

Furthermore, in such a dampening unit housing or the housing longitudinal parts may be produced in a bending process, wherein at least one housing longitudinal part has a plurality of bending edges, and wherein all bending edges of the at least one housing longitudinal part substantially parallel to each other. Instead of the bending process, other forming or shaping processes can be used.

The end regions may be pinned in the grooves and / or screwed and / or glued in such a dampener housing. Fixing may also be in the form described with respect to the first aspect.

A third aspect relates to a moistening device of a spray dampening with a dampening unit housing described in relation to the second aspect, further comprising a spray bar support and a spray bar, wherein the spray bar is connected via the spray bar support with the dampening unit housing such that the spray bar between a working position and a service position is pivotable, wherein the spray bar in the service position in Relative to Sprühbalkenhalterung has at least one degree of freedom, which allows the spray bar is removed from the Sprühbalkenhalterung, and wherein the spray bar, this at least one degree of freedom is taken when swiveling in the working position.

The dampening unit housing, which could also be referred to as a spray housing, can be attached to a machine frame of the printing press or the dampening unit. The dampening box may extend parallel to and along the body to be humidified. The body to be moistened can be a fountain roller of the dampening unit. It may be provided on the spray bar dampening spray nozzles, which may be freely accessible in the service position from outside the dampening unit housing. In the art, and also in the sense used here, the term degree of freedom describes the possibility of movement of bodies in space. The term is often used in the context of joints, and refers to the number and type of possible movements that the joint can perform. It is based on the assumption that a body has three rotational and three translatory degrees of freedom in space. A joint is when two bodies communicate with each other in such a way that at least one of the six degrees of freedom of the other body is taken via the articulated relationship of one body to the other. The degree of freedom of the spray bar in the service position can be a translational degree of freedom. The translatory degree of freedom can be given on the spray bar in nozzle spray direction in the service position. Without the degree or degrees of freedom in the service position, the spray bar in the working position may have a position defined relative to the dampening unit housing, which maintains a distance of the spray nozzles from the one to be moistened Body pretends. Working position is the position in which the spray bar is in operation of the spray dampening unit. The body to be moistened may be, for example, a roller to be moistened, in particular a ductor roller of the spray dampening unit.

Another embodiment relates to such a moistening device of a spray dampening unit, wherein the spray bar is pivotable together with the Sprühbalkenhalterung between the working position and the service position.

Furthermore, in a further embodiment of such a moistening device, the spray bar holder may comprise two substantially U-shaped profiles each having two legs, the spray bar being slidably held in the service position in the U-shaped profiles between the legs of the U-shaped profiles. In this embodiment, the spray bar may have a displaceability in the direction of a longitudinal extension of the legs, ie in the removal direction. Thus, at least one translatory degree of freedom (displacement in the withdrawal direction) can be provided. It is also conceivable another design of a longitudinal guide which provides a translatory degree of freedom in removal direction. The translatory degree of freedom in the withdrawal direction may be directed in a direction which is parallel to a radius extending from the pivot axis.

Furthermore, such a moistening device may have a design in which the U-shaped profiles are arranged on a service flap such that when opening the service flap, the U-shaped profiles are pivoted together with the spray bar from the dampening unit to the service position. A service door defines a flap on the dampening unit housing a humidifying device, through which access to the spray bar for the purpose of its maintenance, etc. can be granted. The service door may extend substantially the length of the spray bar.

Furthermore, such a moistening device may have a configuration in which the dampening unit housing forms a substantially sealed spray chamber in the spraying direction in front of the spray bar in the working position of the spray bar, wherein the dampening unit housing has an inspection flap in the region of the spray chamber via which the spray chamber is accessible from outside the dampening unit housing , In this case, the inspection flap can be arranged so that a sighting of the spray bar can be made in the working position. The inspection flap can be checked spray pattern, contamination of the spray room and / or the spray nozzles. The inspection flap may extend substantially the length of the spray bar. Essentially completed refers to the working state of the dampening unit, in which the dampening unit is arranged in close proximity to the body to be humidified, so that the body to be humidified blocks a spray opening in the dampening unit housing the spray chamber on one side. The body to be moistened may e.g. to be a fountain roller of a dampening unit.

A further embodiment relates to such a moistening device in which the spray bar is subjected to the at least one degree of freedom when swiveling into the working position by swiveling in a holding region of the spray bar into a guide opening of a positioning element. A holding region of the spray bar can be provided via a corresponding design of a spray bar cross-section corresponding to a guide opening cross-section. For example, the spray bar cross section may be substantially rectangular in shape, and the guide opening cross section may include, for example, at least one planar abutment area to which one side of the rectangular spray bar cross section is applied in the service position. The planar contact area can run transversely or perpendicular to the spraying direction of the spray nozzles. About the plant of the spray bar at the investment area, the distance between the spray bar and eg the ductor roller in spray direction can be specified.

A fourth aspect relates to a dampening device of a dampening system with a dampening unit housing described in relation to the second aspect, further comprising a positioning element and a spray bar, the positioning element having a mounting area and a contact area, wherein the positioning element is mounted exchangeably on the dampening unit housing via the mounting area, and wherein the contact area is designed such that the spray bar can be brought into contact with the contact area of the positioning element so that a defined position of the spray bar in relation to the dampening unit housing can be ensured via the contact area. The mounting area refers to the area of the positioning element over which the positioning element can be mounted in the dampening unit housing. The contact area is an area with functional areas at which a contact contact between spray bar and positioning element can be provided. The contact area may have surface areas which are adapted to the contour of the spray bar in corresponding surface areas. The surface areas of the contact area may correspond to the surface design of the spray bar in the holding area of the spray bar. One or more positioning elements can be provided for the positioning of the spray bar in the dampening unit per spray bar. A positioning element may e.g. be configured plate-shaped and / or mounted on a side part of the dampening unit housing. For several positioning elements per spray bar, these may be e.g. be provided on both sides of the dampening unit housing at the ends of the spray bar. An arrangement in the central region of the spray bar in its working position is conceivable.

Such a moistening device may have a design in which the moistening device has a fine adjustment device via which the exchangeable mounting of the positioning element on the dampening unit housing can be effected and by means of which the position of the positioning element relative to the dampening unit housing can be fine-tuned. Such a fine adjustment device can eg via a screwing of the positioning over slots respectively. The slots can be arranged for example in the side panels of the dampening unit housing and / or in the respective positioning element itself.

In this case, such a moistening device may comprise a set of positioning elements in which the contact areas have different positions relative to the mounting areas, so that a coarse adjustment of the position of the spray bar in the dampening unit housing can be undertaken via the choice of the or the respective positioning elements. The positioning elements may e.g. as substantially plate-shaped castings, in particular injection-molded parts, are provided. The positioning can be made in one piece and / or plastic.

A further embodiment relates to such a moistening device, in which the abutment region of the positioning element is provided in the region of a guide opening of the positioning element, into which the spray bar can be inserted into a working position and / or removed therefrom.

Also possible is a design of such a humidifying device, which further comprises the features described above in relation to the third aspect of the invention.

Furthermore, such a moistening device may have a design in which the guide opening of the positioning element has an opening area with an opening width which is greater than the corresponding width of the spray bar, and wherein the guide opening has a base area with a basic width which corresponds to the corresponding width of the spray bar , The opening area refers to the area of the positioning element through which the spray bar first passes when it is pivoted to its working position. The basic area refers to the area of the positioning element that surrounds the spray bar on both sides when the spray bar has reached its working position. So it can be about this design of the base width, for example, a clamping of the Sprühbalkens be effected in this position.

Furthermore, in one embodiment of the moistening device, the guide opening of the positioning element can have an elastically deformable locking area which fixes the spray bar in its working position after complete insertion of the spray bar. Such a locking portion may be integral with the positioning member, e.g. be designed as a locking element. Also conceivable is an embodiment of the locking region as an independent component which is mounted on the positioning element or provided and / or mounted independently of the positioning element on the moistening device.

Hereinafter, individual embodiments of the invention will be described by way of example. In this case, the individual embodiments described have, in part, features which are not absolutely necessary in order to carry out the present invention, but which, in certain applications, generally provide desired properties. Thus, embodiments are also considered to be covered by the teaching of the invention, which does not have all the features of the embodiments described below. Further, to avoid unnecessary repetition, certain features are described only with respect to particular embodiments. It should be noted that the individual embodiments should therefore not be considered alone, but that individual embodiments may also be modified by incorporating one or more features of other embodiments.

Detailed description of the drawing

FIG. 1 shows a preferred embodiment of a moistening device 10 according to the invention in an isometric view.

In the figure, the moistening device 10 is shown in a service position in which a spray bar 40 has been removed from a spray bar holder 30.

In the FIG. 1 and in the other figures it was waived, the remaining parts a spray dampening unit or a printing press on which such a spray dampening unit is arranged to show. Therefore, a ductor roller, which can be moistened by the moistening device 10, for example, not shown. However, it is apparent that a dampening unit housing 20 of the moistening device 10 on the in FIG. 1 left side has a concave recess which is adapted to the convex surface profile of the ductor roller, so that the moistening device 10 can be brought close to the ductor roller.

The moistening device 10 shown in the service position has a service flap 21 in the rear part of the dampening unit housing 20, which is unfolded in the illustrated service position. Furthermore, an inspection flap 22 is shown in spray direction of the spray bar 40 in front of the spray bar on the dampening unit housing 20, through which the interior of a spray chamber 23 is accessible.

On the service flap 21, a spray bar holder 30 is arranged, which is formed in the illustrated embodiment as a fork-shaped holder. The support may have a substantially U-shaped cross-section and may be secured to the service door 21 as shown, such that opening the service door causes the spray bar support 30 to pivot so that a spray bar 40 placed in the spray bar support 30 is in a service position can be pivoted.

As can also be seen in this figure, the spray bar 40 at its two longitudinal ends holding portions 41, which have a substantially rectangular cross-section. In this case, two of the parallel sides of the rectangular cross section with the opening cross section of the spray bar holder 30, which in this embodiment has the described U-shaped cross section, corrspond. If the spray bar 40 is inserted into the spray bar holder 30 via its holding area 41, it is more likely in the illustrated embodiment to be displaced in the direction of the legs of the spray bar holder 30. On the other hand, it is fixed in the transverse direction.

The other two parallel sides of the rectangular cross-section correspond in the illustrated embodiment with a guide opening 52, which is provided on a positioning element 50. In this case, in each case a positioning element 50 is mounted on both longitudinal ends of the dampening unit housing 20 in the illustrated embodiment. The guide opening 52 has, as in FIG. 2 is shown, an abutment region 51, with which one side of the holding portion 41 comes into contact with the pivoting of the spray bar 40 in the working position. The illustrated guide opening 52 has in this embodiment on the opposite other side on a further wall portion. The distance between this wall region and the abutment region 51 can correspond approximately to the width of the corresponding part of the holding region 41.

After pivoting the spray bar 40 in the working position, which in FIG. 3 is shown, the holding portions 41 are thus pivoted into the guide opening 52, and although the spray bar 40 is not fixed in the Sprühbalkenhalterung 30 in the spray direction of its spray nozzles 42, he is by the interaction of its holding portion 41 with the guide opening 52 in this position in the spray direction fixed. The displaceability which the spray bar 40 still has in the spray bar holder 30 is accordingly taken from it when pivoting into the guide opening 52.

The precise position in the spraying direction, in which the spray bar 40 is fixed in its working position in this way, can be adjusted via a fine adjustment device 60. The fine adjustment device 60 is realized in the illustrated embodiment by elongated holes in a side part of the dampening unit housing 20 and corresponding screws with which the positioning element 50 is fixed in the dampening unit housing 20. The elongated holes can additionally or alternatively also be provided on the positioning element 50, which in the illustrated embodiment is designed as a plate-shaped element and in one piece in the plastic injection molding process can be produced. The elongated holes in the positioning element 50 are in FIG. 4 represented and form a mounting portion 53rd

Further, in the illustrated positioning member 50, a locking portion 55 is provided, which causes a latching of the spray bar 40 in the positioning member 50. The locking portion 55 is the Figures 2 and 3 shown. In the illustrated positioning element 50, the wall region of the positioning element, which lies opposite the abutment region 51, is made significantly shorter, so that an opening region 521 is provided in the guide opening 52 which has an opening width W1 that is significantly greater than the width of the corresponding region At the bottom of the guide opening 52, a base portion 522 is formed, which has a basic width W2, which substantially corresponds to the corresponding width of the holding portion 41.

For a moistening device 10 or for a dampening unit housing 20, a set of positioning elements 50 can be provided which has differently configured positioning elements 50. Such a different embodiment may e.g. The fact that the contact areas 51 of the respective positioning elements 50 have a different distance from the respective mounting area 53 of the respective positioning element 50 relative to the spray direction of a spray bar 40 inserted into the positioning plate.

By choosing a suitable positioning element 50, therefore, a distance between the abutment region 51 and a surface of a ductor roller, which is to be moistened by the moistening device 10, can be preselected. Accurate positioning can then be done via the fine adjustment device 60.

FIG. 5 shows components of the dampening unit housing 20 in an exploded view. The dampening unit housing 20 has in the illustrated embodiment, two side parts 24 and a housing longitudinal member 25, which in the illustrated Embodiment is executed in two parts. The housing longitudinal element 25 accordingly has an upper housing longitudinal part 252 and a lower housing longitudinal part 253. The housing longitudinal parts 252, 253 each have an end region 251 on their axial ends facing the side parts 24.

The housing longitudinal parts 252, 253 are formed in the illustrated embodiment as sheet metal parts. The sheet metal parts are made of a substantially flat piece of sheet metal. As material comes e.g. stainless steel, galvanized sheet steel, painted sheet metal, non-metallic materials or similar materials in question. In the plate are various recesses, such as. Holes are formed at the end portions 251, e.g. produced by stamping or by other manufacturing processes. Furthermore, the sheet metal parts have edges 254 which are attached to the sheet metal parts e.g. were produced by bending. In this case, the upper housing longitudinal part 252 has a substantially flat cross-sectional profile. Only the side of the upper housing longitudinal part facing in the operating position of a ductor roller has a short sheet metal area, which is bent obliquely upwards along a bending edge. The axial end regions 251 do not have this short, oblique region of the described cross-sectional profile. On the opposite side of the upper housing longitudinal part 252, the sheet metal part along a bending edge is bent such that in this area two metal layers come to lie parallel to each other. The lower housing longitudinal part 253 has similar longitudinal edges and is additionally bent along a further edge 254 in such a way that it has a substantially L-shaped cross-sectional profile.

Further, the housing longitudinal member 25 may have correspondingly shaped portions at respective locations where e.g. the inspection flap 22 or the service flap 21 can be attached.

The side parts 24 each have grooves 241 into which the end regions 251 of the housing longitudinal parts 252, 253 are inserted. The grooves 241 corresponding to the end regions 251 of the upper housing longitudinal part 252 are in the range the stacked metal layers on a corresponding larger cross-section. The grooves 241 corresponding to the end regions 251 of the lower housing longitudinal part 253 furthermore have a substantially L-shaped cross-sectional profile.

The side parts 24 furthermore also have the already described mounting areas 53.

In the FIG. 5 and the FIG. 6 Fixing elements 26 are shown on the Gehäusendbereichen 251, which contrary to the representation in Figures 5 and 6 only after the insertion of the housing longitudinal element 25 are mounted in the grooves 241. The fixing elements 26 are formed in the embodiment as pins. Holes are provided both in the end regions 251 of the housing longitudinal parts 252, 523 and in the side parts, which are aligned only after the insertion of the housing longitudinal element 25 into the grooves 241 and into which the pins are then inserted. The holes in the side parts 24 may be formed as blind holes. For illustration purposes, the fixing element 26 are already shown in the exploded view in their position at the end portions 251.

FIG. 6 shows the detail of the exploded view FIG. 5 who in FIG. 5 on the left side of the dampening unit housing 20 is shown. Here, in particular, the grooves 241 and the edges 254, which are attached to the housing longitudinal parts 252, 253, better visible.

In FIG. 7 is that in FIG. 6 illustrated end of the dampener housing 20 shown in the assembled state.

As in FIG. 7 it can be seen, in the illustrated embodiment, the end portions 251 of the two housing longitudinal parts 252, 253 as extensions of the housing longitudinal parts 252, 253 are formed. The end portions 251 are inserted in the grooves 241. The grooves 241 are dimensioned such that they fit tightly against the plate of the housing longitudinal parts 252, 253, so that dampening solution, which is in operation the humidifying device 10 could collect at least on the lower housing longitudinal part 253, can not drip at these areas of the dampening unit housing 20. The fit between the end regions 251 and the associated groove 241 can therefore be formed, at least with respect to the lower housing longitudinal part 253, such that this connection region is moisture-tight. Alternatively or additionally, the seal can also be effected by additional sealing elements, not shown.

After the end portions 251 have been inserted into the grooves 241, the housing longitudinal parts 252, 253 are fixed in their inserted position. For this purpose, fixing element 26 are used, which are formed in the illustrated embodiment as pins. The pins are inserted into holes, which are presently formed as blind holes, and inserted through holes, which are formed on the end portions 251, so that the end portions are secured to the side members 24. The combination of grooves 241, inserted sheet metal parts and the pinning creates dense and stable joint areas.

Instead of the pins, other fixing elements 26, such as e.g. Rivets, screws or the like can be used.
