Description

Die Erfindung bezieht sich auf eine fahrbare Vorrichtung zum Fertigen eines Straßenbanketts mit einer Fördervorrichtung, einem Einbaukanal und einem Vorratsbehälter für ein Einbaugut, der über die Fördervorrichtung mit dem Einbaukanal verbunden ist, wobei der Einbaukanal eine Austrittsöffnung für das verdichtete Einbaugut aufweist.The invention relates to a mobile device for paving a road shoulder with a conveying device, a paving channel and a storage container for paving material, which is connected to the paving channel via the conveying device, the paving channel having an outlet opening for the compacted paving material.

Die Anmelderin hat das Patent für Deutschland unter Bezugnahme auf DE202020102685U1 freiwillig eingeschränkt und gesonderte Patentansprüche für diesen Staat vorgelegt.The applicant has the patent for Germany with reference to DE202020102685U1 voluntarily restricted and submitted separate patent claims for this state.

Ein Straßenbankett ist der an eine Fahrbahn angrenzende Abschnitt einer Straßenkrone, der beispielsweise durch ein Ableiten von regenbedingten Oberflächenwasser zur Erhöhung der Verkehrssicherheit beitragen kann.A road verge is the section of a road surface adjacent to a roadway, which can contribute to increasing traffic safety, for example by draining off surface water caused by rain.

Zur Fertigung solcher Straßenbankette sind aus der DE4109944A1 und der DE102010025573A1 verfahrbare Bankettfertiger vorbekannt, die einen Vorratsbehälter für ein Einbaugut umfassen. Das im Bunker gelagerte Einbaugut wird über eine Fördervorrichtung zum Fahrbahnrand transportiert und von einer Einbaubohle verdichtet. Als Einbaugut wird üblicherweise ein für Wasser permeables Material wie Kies eingesetzt. Nachteilig daran ist allerdings, dass das Einbaugut aufgrund seiner hohen Rieselfähigkeit nicht formstabil ist, sodass eine häufige Wartung erforderlich ist. Darüber hinaus ergibt sich zwischen einem solchen Straßenbankett und der Fahrbahn eine Stufe, die ein Abdriften von der Fahrbahn begünstigt, ein Wiederauffahren auf die Fahrbahn erschwert und damit eine Gefahrenquelle für Straßenbenützer mit sich bringt.For the production of such road shoulders are from the DE4109944A1 and the DE102010025573A1 mobile verge finisher previously known, which include a storage container for a paving material. The paving material stored in the bunker is transported to the edge of the road via a conveyor and compacted by a paving screed. A material that is permeable to water, such as gravel, is usually used as paving material. The disadvantage of this, however, is that the paving material is not dimensionally stable due to its high pourability, so that frequent maintenance is required. In addition, there is a step between such a shoulder of the road and the roadway, which promotes drifting off the roadway, makes it difficult to drive back onto the roadway and thus poses a risk to road users.

Es wurde daher bereits vorgeschlagen ( WO2017137168A1 ), aus Beton geformte und Querrinnen aufweisende Signalsteine an Fahrbahnrändern zu verlegen. Kommt ein Straßenbenützer von der Fahrbahn auf das von den Signalsteinen gebildete Straßenbankett ab, so bedingt die Profilierung der Signalsteine, die auch zur Ableitung von Oberflächenwasser dient, ein für den Fahrer fühl- und hörbares Signal. Das Verlegen solcher Signalsteine erweist sich allerdings als zeitaufwändiger Prozess, da diese stückweise an die Fahrbahngeometrie angepasst und eingebaut werden müssen. Zudem verlangen solche Signalsteine eine vorgefertigte Tragschicht aus beispielsweise Kies, was den Aufwand für die Fertigung des Straßenbanketts zusätzlich erhöht.It has therefore already been proposed ( WO2017137168A1 ), laying signal stones made of concrete and having transverse channels at the edges of the road. If a road user leaves the carriageway onto the road shoulder formed by the signal stones, the profile of the signal stones, which also serves to drain off surface water, causes a signal that the driver can feel and hear. However, the laying of such signal stones proves to be a time-consuming process, since they have to be adapted to the geometry of the road and installed piece by piece. In addition, such signal stones require a prefabricated base layer made of gravel, for example, which further increases the effort involved in constructing the road shoulder.

Aus JP2013217055A ist ein Asphaltfertiger zum Fertigen einer Straße bekannt. Während der Fertigung der Straße kann durch eine Walze ein Signalrelief in die Asphaltschicht eingeprägt werden. Da das Signalrelief nur während der Fertigung der Straße eingeprägt werden kann, ergibt sich ein aufwändiger Fertigungsprozess.Out of JP2013217055A an asphalt paver for paving a road is known. During the construction of the road, a signal relief can be embossed into the asphalt layer using a roller. Since the signal relief can only be embossed during production of the road, a complex production process results.

Der Erfindung liegt somit die Aufgabe zugrunde, eine fahrbare Vorrichtung zum Fertigen eines Straßenbanketts der eingangs geschilderten Art vorzuschlagen, die die Gefahr eines Abkommens von der Straße verringert und einen raschen und einfachen Einbauprozess ermöglicht.The invention is therefore based on the object of proposing a mobile device for preparing a road shoulder of the type described at the outset, which reduces the risk of straying off the road and enables a quick and simple installation process.

Die Erfindung löst die gestellte Aufgabe dadurch, dass die Austrittsöffnung von einem Abziehrand begrenzt ist, dem in Fahrtrichtung der Vorrichtung gesehen eine Prägewalze zum Aufbringen eines Signalreliefs auf das vom Abziehrand geformte Einbaugut vorgelagert ist. Zufolge dieser Maßnahmen wird das von dem Vorratsbehälter über die Fördervorrichtung zur Austrittsöffnung des Einbaukanals transportierte, vorzugsweise aushärtende Einbaugut, wie beispielsweise Beton, im Einbaukanal zu einem Einbaurohling vorgeformt und dort zumindest aufgrund seines Eigengewichtes und in einer bevorzugten Ausgestaltungsform durch einen Flaschenrüttler verdichtet, wonach der Abziehrand der Austrittsöffnung dem Einbaurohling einen vordefinierten Querschnitt verleiht, sodass ein Einbaugutrohling im an die Fahrbahn angrenzenden Bereich bei der Überfahrt kontinuierlich eingebaut werden kann. Durch den Abziehrand erfährt dieser Einbaugutrohling eine erste Glättung und Höhenanpassung an die angrenzende Fahrbahn. Der Abziehrand kann allerdings den Einbaurohling nicht nur deckseitig nach oben, sondern auch seitlich abziehen und glätten, sodass durch die Formgebung bzw. Kontur des Abziehrandes unterschiedliche Querschnitte des Einbaurohlings gefertigt werden können. Dies kann besonders exakt durchgeführt werden, wenn der Einbaukanal mit seiner Austrittsöffnung gegen die Fahrtrichtung geöffnet ist, wobei zumindest der der Austrittsöffnung vorgelagerte Endabschnitt des Einbaukanals im Wesentlichen parallel zur Fahrbahn ausgerichtet sein kann. Die Ebene der Austrittsöffnung verläuft somit quer zur Fahrbahn. Durch die in Fahrtrichtung vorgelagerte Prägewalze wird dem vorgeformten Einbaugutrohling ein Signalrelief aufgeprägt. Je nach Ausgestaltung der Prägewalze können unterschiedliche Signalreliefe erzeugt werden, wobei sich Prägewalzen mit in Richtung der Rotationsachse der Prägewalze verlaufenden Prägekörpern bewährt haben, da diese ein für einen Autofahrer bei Überfahrt deutlich zu erkennendes Signalmuster erzeugen. Damit das Straßenbankett ein ausreichendes Ableiten von Oberflächenwasser ermöglicht, kann die Rotationsachse der Prägewalze gegenüber der Horizontalen schwenkverstellbar gelagert sein, sodass eine Anschrägung des Straßenbanketts ermöglicht wird. Dies kann auch durch eine konisch geformte Prägewalze erzielt werden.The invention achieves the stated object in that the outlet opening is delimited by a stripping edge, which, viewed in the direction of travel of the device, is preceded by an embossing roller for applying a signal relief to the paving material formed by the stripping edge. As a result of these measures, the preferably hardening paving material, such as concrete, transported from the reservoir via the conveying device to the outlet opening of the paving channel, is preformed in the paving channel into a paving blank and compacted there at least due to its own weight and in a preferred embodiment by a bottle vibrator, after which the pull-off edge the outlet opening gives the paving blank a predefined cross-section, so that a paving material blank can be continuously paved in the area adjacent to the road when crossing. Due to the leveling edge, this paving material blank experiences an initial smoothing and height adjustment to the adjacent one Roadway. However, the pull-off edge can pull off and smooth the built-in blank not only on the cover side upwards, but also laterally, so that different cross-sections of the built-in blank can be produced by the shape or contour of the pull-off edge. This can be carried out particularly precisely if the installation duct is open with its outlet opening against the direction of travel, it being possible for at least the end section of the installation duct which is in front of the outlet opening to be aligned essentially parallel to the roadway. The level of the outlet opening thus runs transversely to the roadway. A signal relief is embossed on the preformed paving material blank by the embossing roller positioned upstream in the direction of travel. Depending on the design of the embossing roller, different signal reliefs can be produced, embossing rollers with embossing bodies running in the direction of the axis of rotation of the embossing roller having proven themselves, since these generate a signal pattern that can be clearly recognized by a motorist when driving over. In order for the road shoulder to allow sufficient drainage of surface water, the axis of rotation of the embossing roller can be mounted such that it can be pivoted relative to the horizontal, so that the road shoulder can be inclined. This can also be achieved with a conically shaped embossing roller.

Um eine Anpassung des Höhenniveaus des Straßenbanketts an die angrenzende Fahrbahn zu ermöglichen, wird vorgeschlagen, dass die Prägewalze einen entlang ihrer Rotationsachse an einen mit Prägekörpern versehenen Prägebereich anschließenden, prägekörperfreien Angleichsbereich zum Anschluss des Straßenbankettes an eine angrenzende Fahrbahn aufweist. Der glatte Angleichsbereich rollt über den Fahrbahnrand und verhindert dadurch ein Versenken der Prägewalze unter das Niveau der Fahrbahn. Gleichzeitig plättet der Angleichsbereich das von der Prägewalze auf die Fahrbahn verdrängte Einbaugut, sodass Unebenheiten auf der Fahrbahn vermieden und die durch ein seitliches Abbrechen geschwächten Fahrbahnränder verstärkt werden. In einer besonders bevorzugten Ausführungsform kann der Angleichsbereich auch so ausgebildet sein, dass er sowohl über den Fahrbahnrand als auch über den Rand des einzubauenden Straßenbanketts rollt, sodass ein ebenflächiger Übergang erreicht wird.In order to enable the height level of the road shoulder to be adjusted to the adjacent lane, it is proposed that the embossing roller have an alignment area, free of stamping bodies, which adjoins an embossing area provided with embossing bodies along its axis of rotation, for connecting the road shoulder to an adjacent roadway. The smooth alignment area rolls over the edge of the road and thus prevents the embossing roller from sinking below the level of the road. At the same time, the alignment area flattens the paving material pushed onto the roadway by the embossing roller, so that bumps on the roadway are avoided and the roadway edges, which are weakened by lateral breaking off, are strengthened. In a particularly preferred embodiment, the adjustment area can also be designed in such a way that it extends over both the edge of the road and the The edge of the road shoulder to be installed rolls so that a level transition is achieved.

Damit das Signalrelief exakt und reproduzierbar auf den Einbaugutrohling aufgebracht werden kann, empfiehlt es sich in einer besonders günstigen Ausführungsform der erfindungsgemäßen Vorrichtung, dass der Prägewalze ein Zerstäuber zum Benetzen der Prägewalzenoberfläche zugeordnet ist. Durch die Benetzung der Prägewalze mit beispielsweise Wasser wird ein Anheften des Einbaugutes, insbesondere im Falle eines aushärtenden Einbaugutes, an der Prägewalze vermieden. In weiterer Folge werden keine Einbaugutrückstände von der Prägewalze mitgerissen, die ein unerwünschtes Signalrelief aufbringen könnten. Werden trotz ausreichender Benetzung kleine Mengen an Einbaugut mitgerissen, so können die Zerstäuber auch als Reinigungsdüsen zur Entfernung dieser Rückstände ausgebildet sein.So that the signal relief can be applied exactly and reproducibly to the paving material blank, it is recommended in a particularly favorable embodiment of the device according to the invention that the embossing roller is assigned an atomizer for wetting the embossing roller surface. By wetting the embossing roller with water, for example, the paving material is prevented from adhering to the embossing roller, particularly in the case of a hardening paving material. As a result, no paving residues are entrained by the embossing roller, which could cause an unwanted signal relief. If, despite sufficient wetting, small amounts of paving material are entrained, the atomizers can also be designed as cleaning nozzles to remove these residues.

Ein besonders gleichmäßiger Einbaurohling entsteht, wenn der Abziehrand des Einbaukanals einen sich entgegen der Fahrtrichtung erstreckenden Abstreifer bildet. Der Abstreifer kann ein starrer plattenförmiger Körper sein, wiewohl auch schwimmend gelagerte Bohlen denkbar sind. Auch können insbesondere für den Fall, dass der Abziehrand in mehreren Richtungen, also beispielsweise sowohl horizontal als auch vertikal verläuft, mehrere Abstreifer für die einzelnen Außenflächen des Einbaurohlings vorgesehen sein.A particularly even installation blank is created when the pull-off edge of the installation channel forms a stripper that extends in the opposite direction to travel. The scraper can be a rigid plate-shaped body, although floating planks are also conceivable. Several wipers can also be provided for the individual outer surfaces of the installation blank, particularly in the event that the pull-off edge runs in several directions, ie, for example, both horizontally and vertically.

Vor allem der Übergang von dem Straßenbankett zur Fahrbahn stellt bei der Straßenbankettfertigung eine große Herausforderung dar. Um Fehlstellen zwischen Fahrbahn und Straßenbankett zu vermeiden, kann der Einbaukanal einen Anschlag für die um das Straßenbankett zu erweiternde Fahrbahn und eine quer zur Fahrtrichtung offene Fügeöffnung zum Anschließen des verdichteten Einbaugutes an die Fahrbahn aufweisen. Durch den Anschlag des Einbaukanals kann dieser unmittelbar entlang des Fahrbahnrandes geführt und ausgerichtet werden. Da neben der Austrittsöffnung auch eine quer zur Fahrtrichtung, nämlich insbesondere zum Fahrbahnrand hin offene Fügeöffnung vorgesehen ist, wird das Einbaugut an den Fahrbahnrand angedrückt. Bei entsprechend hoher Viskosität des Einbauguts bleibt dieses auch nach Aufbringung des Signalreliefs angedrückt, wodurch die Ausbildung von Spalten oder Fehlstellen beim Aushärten des Einbauguts verhindert wird. Demzufolge kann sich kein abzuleitendes Wasser zwischen Fahrbahn und Signalstreifen sammeln, das vor allem im Winter zu frostbedingten Schäden führen würde.Above all, the transition from the road shoulder to the roadway poses a major challenge in road shoulder production. In order to avoid gaps between the roadway and road shoulder, the installation channel can have a stop for the roadway to be expanded by the road shoulder and a joint opening open transversely to the direction of travel for connecting the compacted paving material to the roadway. The installation channel can be guided and aligned directly along the edge of the road by the stop of the installation channel. Since, in addition to the outlet opening, there is also a joining opening which is open transversely to the direction of travel, namely in particular towards the edge of the road, the paving material is pressed against the edge of the road. At accordingly Due to the high viscosity of the paving material, it remains pressed even after the signal relief has been applied, which prevents the formation of gaps or defects when the paving material hardens. As a result, no water to be drained off can collect between the roadway and signal strips, which would lead to frost-related damage, especially in winter.

Besonders einfach zu konstruierende Verhältnisse hinsichtlich der Ausgestaltung des Einbaukanals ergeben sich dabei, wenn die Austrittsöffnung zur Fügeöffnung erweitert ist. Dies bedeutet, dass die Austrittsöffnung und die Fügeöffnung eine gemeinsame Aussparung in der Einbaukanalwand bilden, die damit sowohl gegen die Fahrtrichtung als auch quer dazu, vorzugsweise in Richtung des Fahrbahnrandes durchbrochen ist.Conditions that are particularly easy to construct with regard to the design of the installation channel result when the outlet opening is widened to form the joining opening. This means that the outlet opening and the joining opening form a common recess in the installation duct wall, which is thus broken through both against the direction of travel and transversely thereto, preferably in the direction of the edge of the road.

Um den Übergangsbereich zwischen Fahrbahnrand und Straßenbankett zu verbessern und am Fahrbahnrand bereits vorhandene Abnützungs- und Fehlstellen in einem Arbeitsschritt mit der Bankettfertigung ausbessern zu können, wird vorgeschlagen, dass die Prägewalze einen entlang ihrer Rotationsachse an einen mit Prägekörpern versehenen Prägebereich anschließenden, prägekörperfreien Angleichsbereich zum Anschluss des Straßenbankettes an eine angrenzende Fahrbahn aufweist und dass die Fügeöffnung einen Abschnitt der Einbaukanaldecke durchbricht, der dem Angleichsbereich der Prägewalze in Fahrtrichtung der Vorrichtung gesehen nachgelagert ist. Dadurch wird sichergestellt, dass das Einbaugut nicht nur auf den vertikalen Abschnitt des Fahrbahnrands angedrückt wird, sondern dass ein Teil des Einbauguts auf die Oberfläche des Fahrbahnrandes, nämlich zu genau jenem Bereich, über den anschließend der Angleichsbereich der Prägewalze rollt, geleitet wird.In order to improve the transition area between the edge of the road and the shoulder of the road and to be able to repair wear and imperfections that are already present on the edge of the road in one step with the production of the shoulder, it is proposed that the embossing roller should have an embossing area with embossing bodies along its axis of rotation and an alignment area free of embossing bodies for connection of the road shoulder to an adjacent roadway and that the joint opening breaks through a section of the built-in duct cover which is downstream of the alignment area of the embossing roller as seen in the direction of travel of the device. This ensures that the paving material is not only pressed onto the vertical section of the roadway edge, but that part of the paving material is guided onto the surface of the roadway edge, namely to exactly that area over which the alignment area of the embossing roller then rolls.

Damit Lufteinschlüsse im Einbaugut vor dem Einbau minimiert werden, empfiehlt es sich, dass sich der Einbaukanal entgegen der Fahrtrichtung verjüngt. Demzufolge wird das Einbaugut einer entlang des Einbaukanals steigenden Verdichtung ausgesetzt, sodass eine homogene und lufteinschlussfreie Zusammensetzung des den Einbaukanal verlassenden Einbaugutrohlings erzielt wird.In order to minimize air pockets in the paving material before paving, it is recommended that the paving duct tapers against the direction of travel. As a result, the paving material is subjected to increasing compression along the paving channel, so that a homogeneous and air-locked composition of the paving material blank leaving the paving channel is achieved.

In the drawing, the subject of the invention is shown as an example. Show it

a schematic side view of a device according to the invention for manufacturing a road shoulder and
2
a snippet of one of the 1 corresponding top view on the same scale.

Eine erfindungsgemäße fahrbare Vorrichtung zum Fertigen eines an eine Fahrbahn 1 angrenzenden Straßenbanketts 2 weist, wie insbesondere der Fig. 1 zu entnehmen ist, einen Vorratsbehälter 3 für ein Einbaugut auf. Das im Vorratsbehälter 3 aufbewahrte Einbaugut wird über eine Fördervorrichtung 4 zum Einbaukanal 5 transportiert, in dem dieses verdichtet und anschließend nach Verlassen der Austrittsöffnung 6 im Bereich neben der Fahrbahn 1 eingebaut wird. Die Austrittsöffnung 6 weist dabei einen Abziehrand 7 auf, wobei dieser einen sich entgegen der Fahrtrichtung 8 erstreckenden Abstreifer 9 bildet, der das aufgetragene Einbaugut glättet und dadurch eine Einbaugutrohling 10 vorformt. Es versteht sich dabei von selbst, dass der Abziehrand 7 nicht um die Austrittsöffnung 6 umlaufen muss, sondern nur Abschnitte dieser Austrittsöffnung 6 bilden kann.A mobile device according to the invention for the production of a road shoulder 2 adjacent to a roadway 1 has, in particular the 1 can be seen, a reservoir 3 for an installation material. The paving material stored in the reservoir 3 is transported via a conveying device 4 to the paving channel 5 in which it is compacted and then paved in the area next to the roadway 1 after leaving the outlet opening 6 . The outlet opening 6 has a stripping edge 7 which forms a stripper 9 which extends counter to the direction of travel 8 and which smooths the applied paving material and thereby preforms a paving material blank 10 . It goes without saying that the pull-off edge 7 does not have to run around the outlet opening 6 but can only form sections of this outlet opening 6 .

Ein besonders exakter Einbau des Einbaugutrohlings 10 gelingt, wenn die Ebene der Austrittsöffnung 6 quer zur Fahrbahn 1 verläuft. Für eine prozesstechnisch einfache Erzeugung von einem Straßenbankett 2, das einem Autofahrer ein etwaiges Abkommen von der Straße signalisiert, ist der Austrittsöffnung 6 in Fahrtrichtung 8 eine Prägewalze 11 vorgelagert, die dem Einbaugutrohling 10 ein Signalrelief 12 aufprägt.A particularly precise installation of the paving material blank 10 succeeds when the plane of the outlet opening 6 runs transversely to the roadway 1 . For a process-technically simple production of a shoulder 2, which signals a motorist if he is about to leave the road, an embossing roller 11 is positioned in front of the outlet opening 6 in the direction of travel 8, which embosses a signal relief 12 on the paving material blank 10.

Wie in der Fig. 2 dargestellt ist, weist die Prägewalze 11 einen mit entlang ihrer Rotationsachse verlaufenden Prägekörpern 13 versehenen Prägebereich auf, der an einen prägekörperfreien, also glatten Angleichsbereich 14 anschließt. Der Angleichsbereich 14 wird entlang des Randes der Fahrbahn 1 geführt, wodurch die Prägewalze 11 an das Höhenniveau der Fahrbahn 1 angeglichen wird.Like in the 2 is shown, the embossing roller 11 has an embossing area which is provided with embossing bodies 13 running along its axis of rotation and adjoins an alignment area 14 which is free of embossing bodies and is therefore smooth. The adjustment area 14 is guided along the edge of the roadway 1, whereby the embossing roller 11 is adjusted to the level of the roadway 1.

Ein Mitreißen von bereits eingebautem Einbaugut durch die Prägewalze 11 wird durch eine ständige Benetzung der Prägewalze 11 erreicht. Zu diesem Zweck sind zwei Zerstäuber 15, 16 vorgesehen, wobei ein Zerstäuber 15 dem Prägebereich und ein Zerstäuber 16 dem Angleichsbereich 14 zugeordnet ist. Die Zerstäuber 15, 16 sind dabei als Reinigungsdüsen ausgelegt, sodass sie die Prägewalze 11 im Falle eines trotz Benetzung mitgerissenen Einbaugutrückstandes von diesem Rückstand reinigen.The embossing roller 11 entrains paving material that has already been installed by continuously wetting the embossing roller 11 . Two atomizers 15, 16 are provided for this purpose, one atomizer 15 being associated with the embossing area and one atomizer 16 with the matching area 14. The atomizers 15, 16 are designed as cleaning nozzles so that they clean the embossing roller 11 of this residue if paving residue is entrained despite wetting.

Der Einbaukanal 5 weist einen Anschlag für den vertikalen Abschnitt des Randes der Fahrbahn 1 und neben der Austrittsöffnung 6 eine quer zur Fahrtrichtung 8 fahrbahnseitig offene Fügeöffnung 17 auf, die einen Abschnitt des eine Einbaukanaldecke bildenden Abstreifers 9 durchbricht, der dem Angleichsbereich 14 der Prägewalze 11 in Fahrtrichtung 8 nachgelagert ist. Durch die erfindungsgemäße Ausbildung der Austrittsöffnung 6 und der Fügeöffnung 17 wird der Einbaugutrohling 10 an den vertikalen Abschnitt des Randes der Fahrbahn 1 angedrückt. Überschüssiges Einbaugut wird auf die Oberfläche des Randes der Fahrbahn 1 verdrängt und zwar auf jenen Bereich, den der Angleichsbereich 14 der Prägewalze 11 in weiterer Folge überrollt. Dadurch wird das Einbaugut geglättet und wieder auf den Einbaugutrohling 10 zurückgedrängt. Zufolge dieser Maßnahmen wird eine Spaltenbildung zwischen Fahrbahn 1 und Straßenbankett 2 vermieden und es werden etwaige Schäden im Randbereich der Fahrbahn 1 im gleichen Arbeitsschritt behoben.The installation channel 5 has a stop for the vertical section of the edge of the roadway 1 and, next to the outlet opening 6, a joining opening 17 which is open on the roadway side transversely to the direction of travel 8 and which breaks through a section of the wiper 9 which forms an installation channel cover and which corresponds to the matching area 14 of the embossing roller 11 in Direction of travel 8 is downstream. Due to the design of the outlet opening 6 and the joining opening 17 according to the invention, the paving material blank 10 is pressed against the vertical section of the edge of the roadway 1 . Excess paving material is pushed onto the surface of the edge of the roadway 1, namely onto that area which the alignment area 14 of the embossing roller 11 subsequently rolls over. As a result, the paving material is smoothed and pushed back onto the paving material blank 10 again. As a result of these measures, the formation of gaps between roadway 1 and road shoulder 2 is avoided and any damage in the edge area of roadway 1 is repaired in the same work step.

Zur Vermeidung von Lufteinschlüssen kann sich der Einbaukanal 5 einerseits in einer vertikalen und andererseits in einer entgegen der Fahrtrichtung 8 verlaufenden Richtung verjüngen. Demzufolge ist das Einbaugut während dem Passieren des Einbaukanals 5 einer steigenden Verdichtung ausgesetzt.In order to avoid air inclusions, the installation channel 5 can taper on the one hand in a vertical direction and on the other hand in a direction running counter to the direction of travel 8 . As a result, the paving material is exposed to increasing compaction while passing the paving channel 5 .
