ADHESIVE NOZZLE HAVING A PLURALITY OF OUTLET OPENINGS
DESCRIPTION
The present invention relates to an adhesive nozzle having an outlet opening and to a method for introducing adhesive material into an adhesive gap.
A number of adhesive nozzles that may be used for instance for filling an adhesive gap with adhesive material are already known from the prior art. For instance gluing nozzles are employed in window construction for joining glass panes to a frame. The way the adhesive material is applied to the adhesive gap is critical for holding the pane in the frame and thus for quality.
One common type of gluing of glass panes is so-called rebate gluing. In rebate gluing, an adhesive nozzle is inserted between a glass pane and a casement of the frame and the entire rebate is filled with adhesive. Since the depth of the rebate is delimited by the casement, when sufficient adhesive is added the adhesive is slightly compressed. This causes more pressure to build up between the pane and the casement, which overall leads to a more secure seat and better gluing of the pane. However, more adhesive is used than would actually be needed for just gluing the pane, since for gluing the pane to the casement, it is first necessary to fill a dead space in the rebate, in which dead space there is no contact between the adhesive and the glass pane.
In addition, there is the risk that given the large quantity of adhesive used it will escape from the rebate because for instance too much adhesive is fed into the adhesive gap.
This is not desired and itself requires countermeasures, for instance providing a directly extruded lip on the casement profile in the area of the rebate. In addition to excessive consumption of adhesive, a more complicated device or embodiment of the casement is also required for the known adhesive use. Moreover, this procedure is less variable, if for instance glass panes having different thicknesses are to be used and thus the shape of each adhesive gap is different.
For this reason an alternative method for gluing glass edges has been developed. In it, an adhesive nozzle does not dip into the gap, but rather sits on the side of the glass pane that is at a distance from the rebate. Regardless of the thickness of the glass pane, in this method the same amount of adhesive is always applied. In contrast to rebate gluing, the entire space between the glass pane and the casement is not filled with adhesive material.
Although this does save on adhesive, there is still the risk that the glass pane and the casement will not be joined well if the adhesive applied does not stay adhered to the glass pane. This risk is particularly acute if the adhesive introduced is not compressed. The result may be that the adhesive is not in contact with the entire surface of the glass pane or casement, and also other properties in addition to the gluing, such as for instance an insulating or sealing function, may not be adequately satisfied.
In order to better compress the adhesive when it is discharged from the adhesive nozzle, before it exits the nozzle the adhesive is therefore diverted such that it exits against the movement direction for the nozzle. Thus a certain back pressure occurs from the adhesive already applied, which causes compression in the exiting adhesive.
However, it is a drawback of this system that a large quantity of adhesive is used in order to provide adequate attachment of the glass pane to the casement.
Nozzles, in particular application nozzles, having a plurality of outlet openings are known from the prior art. For instance, a multiple glue nozzle having a plurality of openings, especially two openings, that is for applying glue to paper edges is known from DE 101 56 691 A1. The glue may be applied for instance through openings that are behind one another, above one another, or diagonally offset.
DE 41 00 694 A1 discloses a device that makes it possible when using a dual nozzle to apply to a glass pane, in the same work step, both a line of butyl rubber that acts as a spacer and a line of an elastically hardening two-component plastic that acts as a seal.
Known from EP 1 891 865 A1 is a gumming device having two gumming mechanisms for applying two glue tracks, preferably one cold glue water track and one hot glue water track, to a wrapping material strip of a filter or tobacco rod. Furthermore, descries a material application device for producing a tactile marking on a surface, which device has at least one nozzle opening and in particular has two nozzle openings.
It is therefore the object of the invention to make available an adhesive nozzle that avoids the aforesaid drawbacks.
This object is attained with an adhesive nozzle in accordance with patent claim 1 and a method in accordance with patent claim 11. Advantageous embodiments are the subject-matter of the subordinate claims.

For instance, a multiple glue nozzle having a plurality of openings, especially two openings, that is for applying glue to paper edges is known from DE 101 56 691 A1. The glue may be applied for instance through openings that are behind one another, above one another, or diagonally offset.
DE 41 00 694 A1 discloses a device that makes it possible when using a dual nozzle to apply to a glass pane, in the same work step, both a line of butyl rubber that acts as a spacer and a line of an elastically hardening two-component plastic that acts as a seal.
Known from EP 1 891 865 A1 is a gumming device having two gumming mechanisms for applying two glue tracks, preferably one cold glue water track and one hot glue water track, to a wrapping material strip of a filter or tobacco rod. Furthermore, descries a material application device for producing a tactile marking on a surface, which device has at least one nozzle opening and in particular has two nozzle openings.
It is therefore the object of the invention to make available an adhesive nozzle that avoids the aforesaid drawbacks.
This object is attained with an adhesive nozzle in accordance with patent claim 1 and a method in accordance with patent claim 11. Advantageous embodiments are the subject-matter of the subordinate claims.
In accordance with the invention, the adhesive nozzle has a first outlet channel having at least a first outlet opening and has at least a second outlet channel having a second outlet opening. At least one of the outlet openings has a smaller cross-section than at least one other outlet opening. Providing the outlet openings with different cross-sections makes it possible for the discharge width of the adhesive material in the adhesive gap to be different. Thus adhesive material exiting via the at least one outlet opening having the smaller cross-section has a higher flow speed than the adhesive material exiting via the other outlet opening. The adhesive material may attain a greater penetration depth into the adhesive gap due to the higher flow speed.
Providing another outlet channel in the adhesive nozzle enables improved compression of applied adhesive material in the adhesive gap. Thus it is inventively assured that adhesive material that has exited via the outlet opening meets an adhesive material that has already exited via another outlet opening. Because the two adhesive materials that have exited meet in the adhesive gap, they are compressed there. Due to the compressed adhesive material, it is possible to attain a better and more rapid adhesion of the adhesive material to a glass pane or a casement of a frame or the like, since the compressed adhesive material expands in one direction to the glass pane and the frame. Because the adhesive material is compressed, the amount introduced into the adhesive gap may be reduced, since it is no longer necessary to fill the entire adhesive gap with adhesive material. This can involve economic advantages.
The channel trailing in the movement direction of the adhesive nozzle shall be considered the first outlet channel in the following. The channel preceding in the movement direction shall be considered the second outlet channel. In the following it is assumed that the cross-section of the first outlet opening for the first outlet channel is larger than the cross-section of the second outlet opening for the second outlet channel. The flow cross-section through which the adhesive material flows and that is provided perpendicular to the outlet channel center access shall be considered the cross-section. The section of the nozzle head that faces the adhesive gap shall be considered the adhesive nozzle in the context of the invention. The adhesive nozzle may be embodied integrally with the nozzle head or in multiple parts with the nozzle head.
Providing another outlet channel in the adhesive nozzle enables improved compression of applied adhesive material in the adhesive gap. Thus it is inventively assured that adhesive material that has exited via the outlet opening meets an adhesive material that has already exited via another outlet opening. Because the two adhesive materials that have exited meet in the adhesive gap, they are compressed there. Due to the compressed adhesive material, it is possible to attain a better and more rapid adhesion of the adhesive material to a glass pane or a casement of a frame or the like, since the compressed adhesive material expands in one direction to the glass pane and the frame. Because the adhesive material is compressed, the amount introduced into the adhesive gap may be reduced, since it is no longer necessary to fill the entire adhesive gap with adhesive material. This can involve economic advantages.
The channel trailing in the movement direction of the adhesive nozzle shall be considered the first outlet channel in the following. The channel preceding in the movement direction shall be considered the second outlet channel. In the following it is assumed that the cross-section of the first outlet opening for the first outlet channel is larger than the cross-section of the second outlet opening for the second outlet channel. The flow cross-section through which the adhesive material flows and that is provided perpendicular to the outlet channel center access shall be considered the cross-section. The section of the nozzle head that faces the adhesive gap shall be considered the adhesive nozzle in the context of the invention. The adhesive nozzle may be embodied integrally with the nozzle head or in multiple parts with the nozzle head.
It should be noted that embodiments are also possible in which the channel preceding in the movement direction has a larger cross-section than the channel trailing in the movement direction.
In one preferred embodiment, first adhesive material is applied via the second outlet opening with the smaller cross-section and then adhesive material is applied via the first outlet opening. What this achieves is that adhesive material that has exited via the second outlet opening acts as a barrier in the adhesive gap for the adhesive material that has exited from the first outlet opening. Ultimately, in accordance with the invention the position or penetration depth of the adhesive material in the adhesive gap may be adjusted in a simple manner since the adhesive material adheres in the adhesive gap wherever the adhesive material that has exited from the first outlet opening meets the adhesive material that has exited from the second outlet opening. The adhesive material is preferably compressed in an area of the adhesive gap that is provided between the adhesive nozzle and the adhesive gap floor. As mentioned in the foregoing, the penetration depth of the adhesive material is a function of the cross-section of the outlet openings.
In one preferred embodiment, the outlet openings for the outlet channels may be arranged behind one another in a movement direction for the adhesive nozzle in which the adhesive nozzle is moved when discharging the adhesive material. This means that in one end face of the adhesive nozzle a connection axis between the outlet opening center points of the two outlet openings is aligned with a movement axis of the adhesive nozzle that runs in the movement direction. Such an arrangement of the outlet openings advantageously increases the compression on the adhesive already applied from an outlet opening.
Alternatively, the outlet openings may be arranged behind one another with respect to the movement direction of the adhesive nozzle such that their outlet opening center points are offset relative to the movement direction of the adhesive nozzle or a connection axis between the outlet opening center points is not aligned with the movement axis of the adhesive nozzle. Furthermore, the outlet openings may be arranged such that a connection axis between the outlet opening center points is perpendicular to the movement axis of the adhesive nozzle. When there are a plurality of outlet openings, any desired arrangement of the outlet openings relative to one another that may be embodied as a function of the adhesive gap to be glued is possible.
In one preferred embodiment, first adhesive material is applied via the second outlet opening with the smaller cross-section and then adhesive material is applied via the first outlet opening.

Ultimately, in accordance with the invention the position or penetration depth of the adhesive material in the adhesive gap may be adjusted in a simple manner since the adhesive material adheres in the adhesive gap wherever the adhesive material that has exited from the first outlet opening meets the adhesive material that has exited from the second outlet opening. The adhesive material is preferably compressed in an area of the adhesive gap that is provided between the adhesive nozzle and the adhesive gap floor. As mentioned in the foregoing, the penetration depth of the adhesive material is a function of the cross-section of the outlet openings.
In one preferred embodiment, the outlet openings for the outlet channels may be arranged behind one another in a movement direction for the adhesive nozzle in which the adhesive nozzle is moved when discharging the adhesive material. This means that in one end face of the adhesive nozzle a connection axis between the outlet opening center points of the two outlet openings is aligned with a movement axis of the adhesive nozzle that runs in the movement direction. Such an arrangement of the outlet openings advantageously increases the compression on the adhesive already applied from an outlet opening.
Alternatively, the outlet openings may be arranged behind one another with respect to the movement direction of the adhesive nozzle such that their outlet opening center points are offset relative to the movement direction of the adhesive nozzle or a connection axis between the outlet opening center points is not aligned with the movement axis of the adhesive nozzle. Furthermore, the outlet openings may be arranged such that a connection axis between the outlet opening center points is perpendicular to the movement axis of the adhesive nozzle. When there are a plurality of outlet openings, any desired arrangement of the outlet openings relative to one another that may be embodied as a function of the adhesive gap to be glued is possible.
The outlet channels may be embodied within the adhesive nozzle such that the courses of the outlet channel center axes for the two outlet channels may be parallel to one another or not. Appropriate embodiment of the outlet channels with respect to one another may further increase compression of the applied adhesive. This may then result in improved quality of the gluing. The outlet channels may be provided in the adhesive nozzle such that an obtuse angle a, 13 is formed between the movement axis of the adhesive nozzle and at least one outlet channel center axis, which again improves compression of the adhesive. The angles a and II may be in the range of 90 to 1800, preferably between 100 and 110 , and may be equal or not equal.
Naturally when there are more than two outlet channels it is possible for the outlet channel center axes to run parallel to one another or not parallel to one another, depending on the intended purpose of the adhesive nozzle.
The adhesive nozzle or a part of the adhesive nozzle that is provided with an outlet channel may also be produced from an elastic material. The outlet channels and/or the adhesive nozzle may be provided such that they may be heated. Thus it is possible to pre-heat the adhesive material that is to be discharged, which then may make it easier to process the adhesive material.
The outlet channels may be connected to the same adhesive feed. Alternatively, the outlet channels may be connected to separate adhesive feeds. When using two-component or multi-component adhesives, providing separate adhesive feeds has the advantage that the individual components of the adhesive do not mix with one another until they exit the adhesive nozzle.
In one advantageous embodiment of the invention, at least one bore that is connected to the feed channel may be provided on the adhesive nozzle. A bore center axis may run perpendicular to the feed channel center axis. An adjusting screw for adjusting the cross-section of the feed channel may be inserted into the bore. Another bore may be connected to a line via which for instance another component of a multi-component adhesive is fed to the adhesive nozzle.
It should be noted that the present invention and its embodiments may be employed for more than just applying adhesive material when attaching glass panes in a frame, especially a casement frame. In fact, the invention is suitable in general for using adhesive material in joints of many types, for instance especially also in laying floors, etc.

Another bore may be connected to a line via which for instance another component of a multi-component adhesive is fed to the adhesive nozzle.
It should be noted that the present invention and its embodiments may be employed for more than just applying adhesive material when attaching glass panes in a frame, especially a casement frame. In fact, the invention is suitable in general for using adhesive material in joints of many types, for instance especially also in laying floors, etc.
It should further be noted that the material applied through the adhesive nozzle does not have to be only adhesive material. It is just as possible for the nozzle to be used for introducing other materials into gaps or joints provided for this purpose, for instance when tiling or the like. In the context of this application, "adhesive nozzle,"
"adhesive material," etc., shall therefore be construed as an example for those fields of application in which viscous materials are to be introduced into a cavity or joint, etc., through a nozzle, without completely filling this cavity or joint, etc. Naturally the present invention is also suitable for completely filling cavities, however.

Fig. 1 depicts a nozzle head 10 for gluing a glass pane 11 to a frame 12, for instance a window or door frame. The frame 12 has a first section 121 that is parallel to an end face of the glass pane 11 that faces the frame 12 and has a second section 122 that is parallel to a glass pane side that faces the interior space I or the exterior space A.
The first section 121 of the frame 12 is joined to the second section 122 so that the lateral cross-section of the frame 12 is essentially L-shaped. The glass pane side facing the exterior space A is positioned on the second section 122 of the frame 12 via a spacer 20 and is arranged such that an adhesive gap 13 is formed between the end face of the glass pane 11 that faces the first section of the frame 12 and the first section of the frame 12.
At its end facing the adhesive gap 13 the nozzle head 10 has an adhesive nozzle 1.
As shall be described in detail later, the adhesive nozzle 1 is embodied such that it is placed onto the glass pane side that is parallel to the second section of the frame 12 and an adhesive is applied to the adhesive gap 13.
"adhesive material," etc., shall therefore be construed as an example for those fields of application in which viscous materials are to be introduced into a cavity or joint, etc., through a nozzle, without completely filling this cavity or joint, etc. Naturally the present invention is also suitable for completely filling cavities, however.

Fig. 4 is a sectional view of an inventive adhesive nozzle.
Fig. 1 depicts a nozzle head 10 for gluing a glass pane 11 to a frame 12, for instance a window or door frame. The frame 12 has a first section 121 that is parallel to an end face of the glass pane 11 that faces the frame 12 and has a second section 122 that is parallel to a glass pane side that faces the interior space I or the exterior space A.
The first section 121 of the frame 12 is joined to the second section 122 so that the lateral cross-section of the frame 12 is essentially L-shaped. The glass pane side facing the exterior space A is positioned on the second section 122 of the frame 12 via a spacer 20 and is arranged such that an adhesive gap 13 is formed between the end face of the glass pane 11 that faces the first section of the frame 12 and the first section of the frame 12.
At its end facing the adhesive gap 13 the nozzle head 10 has an adhesive nozzle 1.
As shall be described in detail later, the adhesive nozzle 1 is embodied such that it is placed onto the glass pane side that is parallel to the second section of the frame 12 and an adhesive is applied to the adhesive gap 13.
Fig. 2 is a detailed view of the nozzle head 10, which is connected at one end to a mixer 14 and at the end opposing the mixer 14 is connected to the adhesive nozzle 1. The mixer 14 is provided for adding the material to be applied, in this case preferably adhesive, to the nozzle head 10 and ultimately to the adhesive nozzle 1. The adhesive nozzle 1 and thus the nozzle head 10 and the mixer 14 may move in a movement direction B.
The adhesive nozzle 1 has a first outlet opening 3 on an end face 2 on the adhesive nozzle 1 that faces the adhesive gap 13 and has a second outlet opening 4, as is depicted in Fig. 3. In Fig. 3, an area of the end face 2 in which the outlet openings 3, 4 are embodied shall be called a lower area to refine the description. An area of the adhesive nozzle 1 opposing the lower area of the end face 2 shall be called an upper area. The end face 2 and thus jointly also the entire cross-section of the adhesive nozzle 1 tapers upward, starting from the lower area, to a pre-determined width.
The outlet openings 3, 4 are embodied in an edge area of the end face 2. The end face 2 of the adhesive nozzle 1 has a constant width in the area in which the outlet openings 3, 4 are arranged. The outlet openings 3, 4 in the embodiment depicted are arranged behind one another along the movement direction B in which the adhesive nozzle is moved when the material is being applied. That is, a connection axis (not shown in the figures) is aligned between the outlet opening center points and the movement direction B. The second outlet opening 4 has a smaller cross-section that the first outlet opening 3.
In addition, the adhesive nozzle 1 preferably has two bores 5 in an adhesive nozzle side 7 that is perpendicular to the end face 2. The bores 5 are provided with a thread. The adhesive nozzle 1 may be connected via the bores to additional components, not shown in the figures, such as for instance an adjusting screw and/or another adhesive material feed line.
Fig. 4 depicts a cross-section through the adhesive nozzle 1 in the preferred embodiment of the invention. Starting from the first and second outlet openings 3, 4, the adhesive nozzle 1 has bores that shall be called 3A and 4A in the following.
The outlet channels 3A, 4A extend from the outlet openings 3, 4, that is, from the end face 2 of the adhesive nozzle 1, into the interior of the adhesive nozzle 1 in the direction of the nozzle head 10 illustrated in Figure 2. The outlet channels 3A, 4A are arranged in the adhesive nozzle 1 such that the outlet channel center axes A1, A2 run parallel to one another and form =
an obtuse angle a, with the movement axis that runs in the movement direction B of the adhesive nozzle 1.
In the interior of the adhesive nozzle the outlet channels 3A, 4A are connected to a feed channel 6. In the preferred embodiment the feed channel 6 is a center bore in the adhesive nozzle 1 and runs in a direction away from the end face 2. The feed channel 6 is arranged in the adhesive nozzle 1 such that a feed channel center axis Z1 does not run parallel to the outlet channel center axes A1, A2. The feed channel center axis Z1 runs perpendicular to the movement axis for the adhesive nozzle 1. The feed channel 6 is connected to the nozzle head 10 via a channel (not shown in the figures). This creates a continuous channel from the adhesive nozzle 1 to the mixer 14.
The diameter of the outlet channels 3A, 4A is the same as the diameters of the associated outlet openings 3, 4. The diameter of the second outlet channel 4A
is smaller than the diameter of the first outlet channel 3A, however.
The following briefly describes how the adhesive nozzle 1 is used.
The inventive adhesive nozzle 1 is connected to a nozzle head 10 through which the material to be applied is to be introduced into an adhesive gap 13. To this end the end face 2 of the adhesive nozzle 1 is placed on a surface of the glass pane 11 such that the part of the adhesive nozzle 1 that is provided with the outlet openings 3, 4 projects beyond the edge of the glass pane 11 and the remaining part of the end face 2 of the adhesive nozzle 1 is positioned on the glass pane 11. In this position, the adhesive nozzle 1 is pushed along the edge of the glass pane 11, while adhesive material, due to pressure exerted by the mixer 14, passes through the feed channel 6, outlet channels 3A, 4A, and finally the outlet openings 3, 4. Due to the embodiment of the outlet channels 3A, 4A in the adhesive nozzle 1, described in the foregoing, the adhesive material exits from the end face 2 in a direction opposing the movement axis B for the adhesive nozzle 1 and goes into the adhesive gap 13 between the glass pane 11 and the frame 12. Due to the plurality of outlet openings 3, 4, this is a multi-stage discharge of the adhesive material. This leads to mutual compression of the adhesive material output from the individual outlet openings 3, 4.
The adhesive material output under pressure from the first outlet opening 3 compresses the adhesive material that was already output from the second outlet opening. In addition, adhesive already output from each of the outlet openings 3, 4 is naturally also compressed by the additional material output. In this manner it is possible to attain better = CA 02830651 2013-09-18 compression of the output adhesive material and the quantity of adhesive material to be output may be optimized and reduced to a necessary minimum. In particular the quantity of the adhesive to be used may be adapted to the thickness of the glass pane 11.
Appropriate embodiment of the adhesive nozzle can also make further compression possible, for instance by varying the diameter of the outlet openings or the outlet channels. In addition, the components of two or multi-component adhesives may be applied using different channels. Moreover, providing heating of one of the channels ¨ feed or outlet ¨ can improve the outputability, for instance using the viscosity. It is also possible for the entire adhesive nozzle to be heated for this purpose. This may also be used for better cleaning the nozzle.

The adhesive nozzle 1 has a first outlet opening 3 on an end face 2 on the adhesive nozzle 1 that faces the adhesive gap 13 and has a second outlet opening 4, as is depicted in Fig. 3. In Fig. 3, an area of the end face 2 in which the outlet openings 3, 4 are embodied shall be called a lower area to refine the description. An area of the adhesive nozzle 1 opposing the lower area of the end face 2 shall be called an upper area. The end face 2 and thus jointly also the entire cross-section of the adhesive nozzle 1 tapers upward, starting from the lower area, to a pre-determined width.
The outlet openings 3, 4 are embodied in an edge area of the end face 2. The end face 2 of the adhesive nozzle 1 has a constant width in the area in which the outlet openings 3, 4 are arranged. The outlet openings 3, 4 in the embodiment depicted are arranged behind one another along the movement direction B in which the adhesive nozzle is moved when the material is being applied. That is, a connection axis (not shown in the figures) is aligned between the outlet opening center points and the movement direction B. The second outlet opening 4 has a smaller cross-section that the first outlet opening 3.
In addition, the adhesive nozzle 1 preferably has two bores 5 in an adhesive nozzle side 7 that is perpendicular to the end face 2. The bores 5 are provided with a thread. The adhesive nozzle 1 may be connected via the bores to additional components, not shown in the figures, such as for instance an adjusting screw and/or another adhesive material feed line.
Fig. 4 depicts a cross-section through the adhesive nozzle 1 in the preferred embodiment of the invention. Starting from the first and second outlet openings 3, 4, the adhesive nozzle 1 has bores that shall be called 3A and 4A in the following.
The outlet channels 3A, 4A extend from the outlet openings 3, 4, that is, from the end face 2 of the adhesive nozzle 1, into the interior of the adhesive nozzle 1 in the direction of the nozzle head 10 illustrated in Figure 2. The outlet channels 3A, 4A are arranged in the adhesive nozzle 1 such that the outlet channel center axes A1, A2 run parallel to one another and form =
an obtuse angle a, with the movement axis that runs in the movement direction B of the adhesive nozzle 1.
In the interior of the adhesive nozzle the outlet channels 3A, 4A are connected to a feed channel 6. In the preferred embodiment the feed channel 6 is a center bore in the adhesive nozzle 1 and runs in a direction away from the end face 2. The feed channel 6 is arranged in the adhesive nozzle 1 such that a feed channel center axis Z1 does not run parallel to the outlet channel center axes A1, A2. The feed channel center axis Z1 runs perpendicular to the movement axis for the adhesive nozzle 1. The feed channel 6 is connected to the nozzle head 10 via a channel (not shown in the figures). This creates a continuous channel from the adhesive nozzle 1 to the mixer 14.
The diameter of the outlet channels 3A, 4A is the same as the diameters of the associated outlet openings 3, 4. The diameter of the second outlet channel 4A
is smaller than the diameter of the first outlet channel 3A, however.
The following briefly describes how the adhesive nozzle 1 is used.
The inventive adhesive nozzle 1 is connected to a nozzle head 10 through which the material to be applied is to be introduced into an adhesive gap 13. To this end the end face 2 of the adhesive nozzle 1 is placed on a surface of the glass pane 11 such that the part of the adhesive nozzle 1 that is provided with the outlet openings 3, 4 projects beyond the edge of the glass pane 11 and the remaining part of the end face 2 of the adhesive nozzle 1 is positioned on the glass pane 11. In this position, the adhesive nozzle 1 is pushed along the edge of the glass pane 11, while adhesive material, due to pressure exerted by the mixer 14, passes through the feed channel 6, outlet channels 3A, 4A, and finally the outlet openings 3, 4. Due to the embodiment of the outlet channels 3A, 4A in the adhesive nozzle 1, described in the foregoing, the adhesive material exits from the end face 2 in a direction opposing the movement axis B for the adhesive nozzle 1 and goes into the adhesive gap 13 between the glass pane 11 and the frame 12. Due to the plurality of outlet openings 3, 4, this is a multi-stage discharge of the adhesive material. This leads to mutual compression of the adhesive material output from the individual outlet openings 3, 4.
The adhesive material output under pressure from the first outlet opening 3 compresses the adhesive material that was already output from the second outlet opening. In addition, adhesive already output from each of the outlet openings 3, 4 is naturally also compressed by the additional material output. In this manner it is possible to attain better = CA 02830651 2013-09-18 compression of the output adhesive material and the quantity of adhesive material to be output may be optimized and reduced to a necessary minimum. In particular the quantity of the adhesive to be used may be adapted to the thickness of the glass pane 11.
Appropriate embodiment of the adhesive nozzle can also make further compression possible, for instance by varying the diameter of the outlet openings or the outlet channels. In addition, the components of two or multi-component adhesives may be applied using different channels. Moreover, providing heating of one of the channels ¨ feed or outlet ¨ can improve the outputability, for instance using the viscosity. It is also possible for the entire adhesive nozzle to be heated for this purpose. This may also be used for better cleaning the nozzle.
