Description

Die Erfindung bezieht sich auf einen aus offenzelligem, vorkomprimiertem Schaumstoff bestehenden, insbesondere zur Fugenabdichtung dienenden Dichtungsstreifen mit verzögerter Rückstellung, welchem in Flächenverbindung eine die Rückstellung des Schaumstoffes mitmachende, dehnbare Folie zugeordnet ist.The invention relates to an open-cell, pre-compressed foam, in particular for sealing joints, with a delayed reset, which is associated in surface connection with an elastic film that resets the return of the foam.

Eine Ausgestaltung dieser Art ist durch die DE-OS 31 33 271 bekannt. Dort liegt die dehnbare Folie auf der Breitfläche eines zu einer Rolle zusammengewickelten, komprimierten Schaumstoffstreifens. Zum definierten Ablösen der flächenverbundenen Folie ist diese längs einer spiralförmigen, an der Dichtungsstreifen-Wickelfuge orientierten Linie zerreißbar. Es kann sich hier um eine Perforation handeln. Ein solcher Dichtungsstreifen ist für große Fugen nicht geeignet. Solche großen Fugen sind bspw. an Parketagen entsprechender Großbauten vorgesehen. Die temperaturabhängige Breitenveränderung dieser Fugen kann bis zu 40 % betragen. Dabei treten hauptsächlich Dichtungsprobleme zwischen den Stirnkanten der Folie und der Fugenwand auf. Hinzu kommt das Problem der Beschädigung der Folie aufgrund der exponierten Lage derselben, die durch eine deutliche konvexe Auswölbung noch markanter ausfällt. Auch diese Gründe tragen dazu bei, daß es nicht zu der wünschenswerten dauerhaften Abdichtung kommt. Der verzögerte Rückstelleffekt beruht auf einem Imprägnierungsverfahren, z. B. mit Chlorparaffin, welches das offenzellige Schaumstoffgerüst, d. h. die Porenwände auskleidet. Der zusammengedrückte Schaumstoff-Dichtungsstreifen stellt sich allmählich wieder zurück. Der Faktor Temperatur ist für diese Rückstellung mitbestimmend. In jedem Fall wird aber eine so große Verzögerung erreicht, daß ausreichend Zeit für die Verlegung besteht. Diese Zeit liegt je nach Ausrüstung im Rahmen von sogar mehreren Stunden. Das entsprechende Herstellungsverfahren ist in der DE-PS 15 69 052 beschrieben.An embodiment of this type is known from DE-OS 31 33 271. There the stretchable film lies on the broad surface of a compressed foam strip that is wound into a roll. In order to detach the surface-attached film in a defined manner, it can be torn along a spiral line oriented at the sealing strip winding joint. It can be a perforation. Such a sealing strip is not suitable for large joints. Such large joints are provided, for example, on the parking floors of corresponding large buildings. The temperature-dependent change in width of these joints can be up to 40%. There are mainly sealing problems between the front edges of the film and the joint wall. In addition, there is the problem of damage to the film due to the exposed position of the film, which is even more pronounced due to a clear convex bulge. These reasons also contribute to the failure to achieve the desirable permanent seal. The delayed reset effect is based on an impregnation process, e.g. B. with chlorinated paraffin, which lines the open-cell foam structure, ie the pore walls. The compressed foam sealing strip gradually comes back back. The temperature factor is a determining factor for this provision. In any case, the delay is so great that there is sufficient time for the installation. Depending on the equipment, this time may even be several hours. The corresponding manufacturing process is described in DE-PS 15 69 052.

Aufgabe der Erfindung ist es, die Abdichtungsverhältnisse bei günstiger Herstellung und Benutzung in breiten Fugen zu verbessern über den Lösungsgedanken, daß die End-Strecklage der Folie mit ausgewogenen Rückstellkraftbelastungen erreicht ist.The object of the invention is to improve the sealing conditions with cheap manufacture and use in wide joints over the idea that the final stretch position of the film is achieved with balanced restoring force loads.

Gelöst ist diese Aufgabe gemäß der Erfindung dadurch, daß die Folie als mit zwei Schaumstoffschichten flächenverbundene Zwischenlage dieser Schichten gestaltet ist.This object is achieved according to the invention in that the film is designed as an intermediate layer of these layers which is surface-connected with two foam layers.

Zufolge solcher Ausgestaltung ist ein gattungsgemäßer Dichtungsstreifen hohen Gebrauchswerts erzielt: Es liegt ein überraschend dichter Sitz der Stirnenden an der Fugenwand vor. Dies resultiert aus der vorteilhaften Innenlage der Folie; beiderseits dieser Lagenebene wirken gleichberechtigte Rückstellkräfte der beiden Schaumstoffschichten. Die erläuterte exponierte Lage ist durch die nunmehrige Einverleibung mit einfachen Mitteln vermieden. Die geschützte Einlagerung gewährleistet Dichtfunktion über längste Gebrauchszeiten. Beiderseits erstrecken sich gleichsam Schutzpolster vor dieser im Grunde empfindlichen Feuchtigkeitssperre. Auch die Einspannstellung wird wirksamer erreicht zufolge beiderseits liegender Rückstell-"Kraftspeicher". Die Lagentreue zwischen Folie und den sie sandwichartig einbettenden Schaumstoffschichten läßt sich mit einfachen Mitteln durch T-förmige, mit ihren T-Schenkeln die fugenwandseitigen Randkanten der Schaumstoffschichten übergreifende Stirnenden der Folie begünstigen. So bleibt die dichtende Kontaktanlage der Stirnenden erhalten; die Stirnenden ziehen sich nicht ein. Eine andere vorteilhafte Möglichkeit besteht darin, daß die Folie als die Schaumstoffschicht ummantelnde Hülle ausgebildet ist. Will man erreichen, daß praktisch gar keine Rückstellkräfte mehr verlorengehen zum Dehnen der Folie, so schlägt die Erfindung bei einem aus offenzelligem, vorkomprimiertem Schaumstoff bestehenden, insbesondere zur Fugenabdichtung dienenden Dichtungsstreifen mit verzögerter Rückstellung, welchem in Flächenverbindung eine die Rückstellung des Schaumstoffes mitmachende Folie zugeordnet ist, vor, daß die Folie als in Rückstellrichtung wellenartig verlaufende Zwischenlage zweier Schaumstoffschichten gestaltet ist, wobei die in Rückstellrichtung weisende Streck-Gesamtlänge der Folie dem Außenmaß des maximal zurückgestellten Dichtungsstreifens entspricht. Hier bildet die Wellung bzw. Kräuselung den Streckvorrat. Ansonsten treten die gleichen beschriebenen Vorteile im Hinblick auf die ausgewogene Einspannstellung des Dichtungsstreifens sowie die hohe Dichtigkeit im Bereich der fugenwandseitigen Stirnkanten auf, nur das nun die volle Kraft der Schaumstoff-"Kraftspeicher" zur Auswirkung kommt. Weiter bringt die Erfindung in Vorschlag, daß die Zwischenlage-Folie mit beiden Schaumstoffschichten klebeverbunden ist. Die diesbezügliche Fesselung erweist sich als stabiler als die von Hause aus vorliegende, aus der Rückstellverzögerungs-Imprägnierung zu nutzenden Haftwirkung. Weiter ist es vorteilhaft, daß die Wellform der Zwischenlage-Folie aus der Vorkomprimierung des Schaumstoffes resultiert. Eine solche Maßnahme hat gegenüber einer Vorwellung der Folie vor allem fertigungstechnische Vorteile; es bedarf keiner besonderen, die Wellung bringenden Vorrichtung. Es ergibt sich eine gut anschmiegende Verbindung zwischen Folie und den seitlichen Schaumstoffschichten. Da die Wellung auch Hinterschnittstrukturen einnimmt bzw. einnehmen kann, liegt praktisch eine in der Holzbearbeitung als Zinken bekannte Verbindungsart in Form einer innigen Verzahnung vor. In vorteilhafter Weise kann die Flächenverbindung durch Einsatz eines dauerelastischen Klebstoffs erreicht werden, wozu die Zwischenlage-Folie beiderseits selbstklebend beschichtet ist. Weiter wird eine Ausgestaltung dahingehend in Vorschlag gebracht, daß die Folie als mit dem Schaumstoffmaterial einheitliche, aufgezogene Haut desselben gestaltet ist. Gebildet wird diese Haut bspw. durch Zuziehen der Poren unter Einsatz eines heißen Rakeis. Endlich bringt die Erfindung bei einer mit Dichtungsstreifen gemäß Anspruch 1 oder 6 abgedichteten Fuge in Vorschlag, daß die fugenwandseitigen Stirnkanten der Folie mit der Fugenwand verklebt sind. Die bspw. mit Epoxydharz bestrichenen Fugenwände bringen je nach Kleber bzw. Kleber-Aushärtungszeit in diesem Bereich einen vorteilhaften verzahnenden Verbund, wobei der Kleber in die offenen Poren eindringen und hier eine vorteilhafte Tiefenverankerung plus Dichtung bringen kann. Die gegenüber dem weichen Schaumstoffgerüst leicht überstehenden Stirnenden bzw. Stirnkanten der Folie tauchen greifen in die Klebemasse ein, so daß hier ein Effekt höchster Abdichtung selbst bei rauhen Fugenwänden erreicht wird.As a result of such an embodiment, a generic sealing strip of high utility value is achieved: the end faces are surprisingly tightly seated on the joint wall. This results from the advantageous inner layer of the film; on both sides of this layer level there are equal restoring forces of the two foam layers. The exposed position explained is avoided by the simple incorporation into the present. The protected storage ensures sealing function over longest periods of use. Protective cushions extend on both sides from this basically sensitive moisture barrier. The clamping position is also reached more effectively due to the resetting "energy store" lying on both sides. The positional accuracy between the film and the foam layers embedding it sandwich-like can be favored with simple means by means of T-shaped end faces of the film which overlap the edge edges of the foam layers on the joint wall side with their T-legs. So the sealing contact system of the foreheads is preserved; the foreheads do not retract. Another advantageous possibility is that the film as the foam layer encasing envelope is formed. If one wants to ensure that practically no restoring forces are lost anymore for stretching the film, the invention proposes a sealing strip with an open cell, pre-compressed foam, in particular for sealing joints, with a delayed reset, to which a sheet that resets the restoration of the foam is assigned in surface connection , before that the film is designed as an intermediate layer of two foam layers which is wave-like in the restoring direction, the total stretching length of the film pointing in the restoring direction corresponding to the outer dimension of the maximally restored sealing strip. Here the curl or crimp forms the stretching stock. Otherwise, the same advantages described occur with regard to the balanced clamping position of the sealing strip and the high level of tightness in the region of the end edges on the joint wall side, only that the full force of the foam "force accumulator" now comes into effect. The invention further proposes that the intermediate layer film be adhesively bonded to both foam layers. The bondage in this regard proves to be more stable than the inherent adhesive effect to be used from the delayed impregnation. It is also advantageous that the corrugated shape of the intermediate layer film results from the pre-compression of the foam. Such a measure has, above all, advantages in terms of production compared to pre-corrugation of the film; no special device which brings the corrugation is required. The result is a well-fitting connection between the film and the side foam layers. Since the corrugation also takes or can take undercut structures, there is practically a type of connection known in woodworking as tines in the form of an intimate toothing. The surface connection can advantageously be achieved by using a permanently elastic adhesive, for which purpose the intermediate layer film is self-adhesive coated on both sides. Furthermore, an embodiment is proposed in such a way that the film is designed as the same, drawn skin of the same with the foam material. This skin is formed, for example, by contracting the Pores using a hot rake egg. Finally, in a joint sealed with sealing strips according to claim 1 or 6, the invention proposes that the end edges of the film on the joint wall side be glued to the joint wall. Depending on the adhesive or adhesive hardening time, the joint walls, coated with epoxy resin, for example, provide an advantageous interlocking bond in this area, whereby the adhesive can penetrate into the open pores and provide an advantageous deep anchorage plus seal. The end faces or front edges of the film, which protrude slightly from the soft foam structure, penetrate into the adhesive, so that an effect of maximum sealing is achieved even with rough joint walls.

Chlorine paraffin, for example, can be used for this. This lines the cell walls 2 '. In the compressed state, these lined cell walls 2 'adhere to one another. This adhesive force is overcome by the restoring force of the foam material. There is a gradual return to the initial structure.

Zwischen den Schaumstoffschichten 1 befindet sich eine dünne Folie 4. Die Folie ist als mit den beiderseits liegenden Schaumstoffschichten 1 flächenverbundene Zwischenlage dieser Schichten gestaltet.There is a thin film 4 between the foam layers 1. The film is designed as an intermediate layer of these layers that is surface-connected to the foam layers 1 lying on both sides.

Bei der in Fig. 2 dargestellten Variante des Dichtungsstreifens D besteht die Zwischenlage-Folie 4 aus die Rückstellung mitmachendem dehnbaren Folienmaterial. Deren entspannte Ausgangs-Flächengröße entspricht der Flächengröße der komprimierten Schaumstoffschichten 1. Die ebene Erstreckungsrichtung der Folie 4 verläuft in Rückstellrichtung R der von den Schmalseiten 1' her komprimierten Schichten. Die Schmalseiten, (d. h. die Dicke) der Schaumstoffschichten 1 besitzen eine Höhe x, die etwa einem Siebtel des Maßes y der Streifenbreite in zurückgestelltem Zustand entspricht.In the variant of the sealing strip D shown in FIG. 2, the intermediate layer film 4 consists of the stretchable film material that makes up the provision. Their relaxed initial area size corresponds to the area size of the compressed foam layers 1. The plane direction of extension of the film 4 runs in the return direction R of the layers compressed from the narrow sides 1 '. The narrow sides (i.e. the thickness) of the foam layers 1 have a height x which corresponds to approximately one seventh of the dimension y of the strip width in the reset state.

Der beim dargestellten Ausführungsbeispiel aus drei Schaumstoffschichten 1 gefertigte Dichtungsstreifen D ist zwischen zwei Leisten 5 gehalten, die so beschichtet sind, daß sich der komprimierte Dichtungsstreifen nach Lösen der die Verpackung V sichernden Umreifungen 6 von den klemmbackenartigen Leisten abnehmen läßt. Als Leisten sind Bretter geeignet. Die die Umreifungen 6 sichernden Klammern sind mit 7 bezeichnet.The sealing strip D made from three foam layers 1 in the illustrated embodiment is held between two strips 5, which are coated in such a way that the compressed sealing strip 6 loosens after the straps 6 securing the packaging V are released can be removed from the jaw-like strips. Boards are suitable as strips. The clips securing the straps 6 are designated by 7.

Das Einbringen der aus dehnfähigem Material bestehenden Folie 4 kann im Durchlaufverfahren geschehen. Sie wird als Streifen zwischen die bspw. durch Walzen komprimierten Schaumstoffschichten 1 gelegt. Auch hier bildet die verzögerte Rückstellung eine vorteilhafte Voraussetzung für diese Ausstattungsart. Die abgelängten Dichtungsstreifen-Stücke werden dann dem Verpacken zugeführt. Eine solche sogenannte Stick-Packung ist durch das DE-GM 83 30 528 der Anmelderin beschrieben.The film 4 made of stretchable material can be introduced in a continuous process. It is placed as a strip between the foam layers 1 compressed, for example, by rolling. Here too, the delayed reset is an advantageous prerequisite for this type of equipment. The cut pieces of sealing strip are then fed to the packaging. Such a so-called stick pack is described by DE-GM 83 30 528 of the applicant.

Nach Entfernen der Leisten 5 wird der noch eine Zeit lang in komprimiertem Zustand verharrende Dichtungsstreifen D in eine Fuge F zu Dichtzwecken eingesetzt. Hierbei treten die porenoffenen Schmalseiten 1' des Dichtstreifens D und die der Fugenwand zugewandten Stirnenden 4' der Folie 4 dichtend gegen die Fugenwand 8. Die Stirnenden 4' sind gemäß Fig. 2 (erstes Ausführungsbeispiel) T-förmig gestaltet derart, daß die gleich lang ausgebildeten T-Schenkel die fugenwandseitigen Randkanten der Schaumstoffschicht-Schmalseiten 1' ankerartig übergreifen und so ein Einziehen der dehnbaren Folie 4 unterbinden. Die T-Schenkel sind mit 4" bezeichnet. Im Querschnitt gesehen, weist die Folie dort ein Doppel-T-Profil auf, wobei der T-Steg die Dehnzone ist. Eine andere Möglichkeit der Sicherung gegen Folien-Schlupf besteht darin, daß die Folie 4 als die Schaumstoffschicht 1 ummantelnde Hülle ausgebildet ist. Diese Variante ist zeichnerisch nicht dargestellt.After the strips 5 have been removed, the sealing strip D, which remains in the compressed state for a while, is inserted into a joint F for sealing purposes. Here, the open-pore narrow sides 1 'of the sealing strip D and the end faces 4' of the film 4 facing the joint wall form a seal against the joint wall 8. The end ends 4 'are T-shaped in accordance with FIG. 2 (first exemplary embodiment) in such a way that they have the same length trained T-leg overlap the edge edges of the foam layer narrow sides 1 'on the joint wall side and thus prevent the stretchable film 4 from being drawn in. The T-legs are designated 4 ". In cross-section, the film there has a double-T profile, the T-web being the expansion zone. Another possibility of securing against film slip is that the film 4 is designed as a sheath encasing the foam layer 1. This variant is not shown in the drawing.

Die Variante gemäß Fig. 3 unterscheidet sich gegenüber der erstbeschriebenen Ausgestaltung dadurch, daß die Folie 4 als in Rückstellrichtung, Doppelpfeil R, wellenartig verlaufende Zwischenlage zweier Schaumstoffschichten 1 gestaltet ist. Die entsprechende Wellform bildet den die Rückstellung mitmachenden Längenvorrat, wobei die in Rückstellrichtung weisende Streck-Gesamtlänge der Folie 4 dem Außenmaß z des maximal zurückgestellten Dichtungsstreifens D entspricht (Fig. 3). Hier gehen gar keine Kräfte in Bezug auf die Rückstellung des Schaumstoffs mehr verloren. So läßt sich bei gleichen Grundmaßen des Dichtungsstreifens D eine noch breitere Fuge F abdichten.The variant according to FIG. 3 differs from the first described embodiment in that the film 4 is designed as an intermediate layer of two foam layers 1 which runs in a wave-like manner in the reset direction, double arrow R. The corresponding corrugation form forms the length reserve that takes part in the provision, whereby the in The total stretch length of the film 4 pointing in the direction of restoration corresponds to the external dimension z of the maximally restored sealing strip D (FIG. 3). No forces are lost here with regard to the resetting of the foam. Thus, with the same basic dimensions of the sealing strip D, an even wider joint F can be sealed.

Die Zwischenlage-Folie 4 ist mit beiden Schaumstoffschichten 1 flächenverbunden. Hierzu dient eine entsprechend beiderseits vorgesehene Selbstklebeschicht 9, welche sowohl mit der Folie 4 als auch mit dem porigen Gerüst 3 der aufliegenden Schaumstoffschichten 1 in Verbindung tritt. Die diesbezügliche Ausstattung ergibt sich aus der Vergrößerung in Fig. 4. Die entsprechend dauerelastische Selbstklebeschicht 9 drückt sich, obwohl das nicht dargestellt ist, noch in die angeschnittenen Zellen 2 hinein, um sich darin zu verankern. Dies geschieht besonders wirksam an hinterschnittenen Porenwand-Abschnitten.The intermediate layer film 4 is connected to the surface with both foam layers 1. For this purpose, a self-adhesive layer 9 is provided, which is provided on both sides and which comes into contact both with the film 4 and with the porous structure 3 of the foam layers 1 lying thereon. The equipment in this regard results from the enlargement in FIG. 4. The corresponding permanently elastic self-adhesive layer 9, although this is not shown, is still pressed into the cut cells 2 in order to anchor it. This happens particularly effectively on undercut pore wall sections.

Die Wellform der Zwischenlage-Folie 4 resultiert aus der Vorkomprimierung des Schaumstoffes. Die gleich flächengroßen Materialien werden in der aus Fig. 1 ersichtlichen Anordnung zusammengeführt, breitflächig gegeneinandergedrückt und dann einer die Komprimierung auch hier von den Schmalseiten 1' her bewirkenden Vorrichtung zugeführt, bis sie den verpackungsgerechten Querschnitt gemäß Fig. 3 aufweisen. Die sich bei der Vorkomprimierung einstellende Wellung ist aus den Fig. 3 und 5 ersichtlich. Es handelt sich um eine reiche Kräuselung, die zusätzlich zu der Rückstellkraft der beiden beiderseits liegenden Schaumstoffschichten selbst noch eine gewisse Rückstellkraft speichert, so daß die hier als lippenartige Stirnkanten auftretenden Stirnenden 4' bei eingesetztem Dichtungsstreifen D gemäß Fig. 5 nachhaltig noch eine gewisse Tendenz einer exponierten Vorstandsstellung besitzen, die eine sehr Dichte, die Wasserundurchlässigkeit begünstigende Anlage an den Fugenwänden 8 bringen. Optimieren läßt sich diese stirnseitige Anlage der vortretenden Stirnkanten 4' noch dadurch, daß die Fugenwände 8 eine Kleberschicht 10 aus Epoxydharz aufweisen. Hier entsteht die aus Fig. 6 ersichtliche, im groben als S-Fuge zu bezeichnende Ineinandergriff-Zone. Auch die die Endbereiche der Folie 4 und benachbarte Schaumstoffschichten 1 miteinander verbindenden Selbstklebeschichten 9 wandern mit in die Kleberschicht 10, mit der sie sich verbinden.The corrugated shape of the intermediate layer film 4 results from the pre-compression of the foam. The materials of the same area are brought together in the arrangement shown in FIG. 1, pressed against one another over a wide area, and then fed to a device which also brings about compression from the narrow sides 1 ′ until they have the cross section according to FIG. 3 suitable for packaging. The corrugation occurring during the pre-compression can be seen from FIGS. 3 and 5. It is a rich crimp that, in addition to the restoring force of the two layers of foam lying on both sides, itself stores a certain restoring force, so that the end faces 4 'appearing here as lip-like end edges sustainably show a certain tendency when the sealing strip D according to FIG. 5 is inserted have exposed board position, which bring a very dense, the water-impermeable system on the joint walls 8. This frontal contact of the protruding front edges 4 'can also be optimized in that the joint walls 8 have an adhesive layer 10 made of epoxy resin. Here comes the From Fig. 6 apparent, roughly referred to as S-joint zone. The self-adhesive layers 9 which connect the end regions of the film 4 and adjacent foam layers 1 to one another also migrate into the adhesive layer 10 to which they are connected.

Die der Fugenwand 8 zugewandten, angeschnittenen Zellen 2 bringen ebenfalls eine günstige Tiefenverankerung durch partiellen Eintritt der Kleberschicht 10 in diese Zellen. Dabei kommt es zu einer ausgewogenen Andrück-Einspannstellung zufolge der Einbettung 4 zwischen zwei im wesentlichen gleich großen Schaumstoffschichten. Durch Mehrlagigkeit können weitere Feuchte-Sperren hintereinanderliegend in gleicher Weise verwirklicht sein, wie dies aus Fig. 5 hervorgeht. Die hier dreischichtige Lamellierung des Dichtungsstreifens D bringt dort eine zweite Feuchte-Sperre.The cut cells 2 facing the joint wall 8 likewise bring about favorable deep anchoring by partial entry of the adhesive layer 10 into these cells. This results in a balanced pressure-clamping position as a result of the embedding 4 between two essentially identical foam layers. Multiple layers of moisture can be implemented one behind the other in the same way by multilayering, as can be seen from FIG. 5. The three-layer lamination of the sealing strip D brings a second moisture barrier there.

Die Folie 4 kann auch integraler Bestandteil der Schaumstoffschicht 1 sein, indem diese bspw. an einer Breitfläche verhautet wird. Gebildet wird diese Haut durch Zuziehen der dortigen Porenfläche unter leichtem Zurückschmelzen des Schaumstoffgerüsts 3 mittels eines Rakels oder dergleichen. Neben einer thermischen Behandlung ist die Verhautung auch über chemische Mittel möglich. Selbst das Aufsprühen einer zu wasserdichten Verhältnissen führenden Haut läßt sich realisieren. Der Aufbau des Dichtungsstreifens D geschieht dann in der oben erläuterten Weise.The film 4 can also be an integral part of the foam layer 1, in that it is, for example, knotted on a wide area. This skin is formed by closing the pore surface there, with the foam structure 3 being melted back slightly by means of a doctor blade or the like. In addition to thermal treatment, skin can also be removed using chemical agents. Even spraying on a skin that leads to watertight conditions can be realized. The construction of the sealing strip D then takes place in the manner explained above.

Die Wellung kann auch als Vorwellung der Folie 4 ausgebildet sein.The corrugation can also be designed as a pre-corrugation of the film 4.

Alle in der Beschreibung erwähnten und in der Zeichnung dargestellten neuen Merkmale sind erfindungswesentlich, auch soweit sie in den Ansprüchen nicht ausdrücklich beansprucht sind.All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
