Description

Gegenstand der Erfindung ist eine Anlage zur Bearbeitung von Laufflächen an Skiern und Snowboards gemäss Oberbegriff des Patentanspruchs 1.The invention relates to a system for processing running surfaces on skis and snowboards according to the preamble of patent claim 1.

Die Laufflächen von Skiern und Snowboards zusammengefasst kurz Skier genannt werden auf harten Pisten und insbesondere in schneearmen Gebieten mechanisch sehr strapaziert und dadurch die Laufeigenschaften negativ beeinflusst bzw. der Reibwiderstand vergrössert. Bei Hochleistungsskiern sind die Laufflächen nicht völlig glatt sondern sie weisen meist eine Struktur in Gestalt von Rillen oder anderen Einprägungen auf, die einerseits durch Abnutzung durch die harten Eiskristalle des Schnees hervorgerufen wird oder eben durch Beschädigungen anderer Art. Um dem Ski wieder die ursprünglichen Eigenschaften zu verleihen oder diesen an spezielle Verhältnisse anzupassen (Weichschnee oder Hartschnee) sind Vorrichtungen bekannt, welche durch einen Schleifvorgang und anschliessendes Bearbeiten die ursprüngliche Struktur wieder aufbringen oder eine Struktur auf Wunsch des Skiläufers erzeugen. Zusammen mit der Strukturierung der Lauffläche müssen auch die Stahlkanten nachgeschliffen werden und/oder der Winkel der Aussenkante zur Unterseite verändert werden.The running surfaces of skis and snowboards, collectively referred to as skis, are subjected to great mechanical stress on hard slopes and, in particular, in snow-poor areas, thereby negatively influencing the running properties and increasing the frictional resistance. In Hochleistungsskiern the treads are not completely smooth but they usually have a structure in the form of grooves or other impressions, which is caused on the one hand by wear by the hard ice crystals of the snow or just by damage of another kind. To the ski back to the original properties give or adapt this to special conditions (soft snow or hard snow) devices are known which reapply the original structure by a grinding process and subsequent editing or create a structure at the request of the skier. Together with the structuring of the tread, the steel edges must also be reground and / or the angle of the outer edge to the underside must be changed.

Seit vielen Jahren sind dazu unterschiedliche Vorrichtungen auf dem Markt, bei denen die Skier an einem Ende der Vorrichtung eingelegt und dann über verschiedene Bearbeitungsstationen geführt werden. Solche Anlagen eignen sich für die Verarbeitung von tausenden von Skiern pro Jahr, nicht jedoch für kleinere Betriebe wie Sportgeschäfte, Servicestationen, etc. Einfache bekannte Vorrichtungen sind in der Lage, die Lauffläche zu schleifen, und gleichzeitig werden durch die Schleifscheiben die Stahlkanten an deren Unterseite plan zu den Laufflächen geschliffen. Grössere Anlagen sind auch ausgerüstet, dass die Seitenkanten in einen festen Winkel neu geschliffen werden. Dabei müssen die Vorrichtungen die Konturen der heute meist sehr taillierten Skiern erfassen und entlang diesen müssen die Schleifscheiben geführt werden.For many years, there are different devices on the market, in which the skis are inserted at one end of the device and then passed through various processing stations. Such equipment is suitable for processing thousands of skis per year, but not for smaller businesses such as sports shops, service stations, etc. Simple known devices are capable of grinding the tread, and at the same time, the grinding wheels cause the steel edges to be underside ground plan to the treads. Larger systems are also equipped that the side edges are re-ground to a fixed angle. The devices must capture the contours of today mostly very waisted skis and along these the grinding wheels must be performed.

Eine Aufgabe der vorliegenden Erfindung besteht nun darin, eine Anlage zu schaffen, mit der alle Bearbeitungsschritte auf kleinem Raum möglich sind und dabei eine optimale Lauffläche erzeugt wird, bei der sowohl die Lauffläche als auch die seitlichen Kanten an die jeweiligen Erfordernisse anpassbar sind.An object of the present invention is to provide a system with which all processing steps In a small space are possible and thereby an optimal tread is generated, in which both the tread and the side edges are adaptable to the respective requirements.

Gelöst wird diese Aufgabe durch eine Anlage gemäss den Merkmalen des Patentanspruches 1. Vorteilhafte Ausgestaltung der Anlage sind in den abhängigen Ansprüchen umschrieben.This object is achieved by a system according to the features of claim 1. Advantageous embodiment of the system are described in the dependent claims.

Es gelingt durch das Festhalten eines Skis mit nach unten gerichteter Lauffläche oder Sohle im Zentrum eines Maschinenrahmes und einem die Bearbeitungswerkzeuge aufnehmenden Wagen, der unter dem festgehaltenem Ski hindurchläuft, die Bearbeitung in sehr engen und damit belagschonenden Toleranzen zu bearbeiten. Der Ski ist dabei dauernd auf einer Vielzahl von Tragrollen abgestützt und behält während der Bearbeitung die für diese notwendige plane Ausrichtung. Mit den im Maschinenrahmen verfahrbaren Tragrollen können diese in sehr kurzen gegenseitigen Abständen den Ski tragen und es können dadurch Durchbiegungen der Skis beim Anpressen der Bearbeitungswerkzeuge vermieden werden. Die Positionierung des Skis im Maschinenrahmen erfolgt auf teils fest angeordneten und teils bewegten Tragrollen, so dass der Ski stets exakt ausgerichtet liegt, wenn die Bearbeitungswerkzeuge unter dem Ski vorbeigeführt werden. Die Bearbeitungswerkzeuge werden durch Distanzsensoren in eingestelltem Abstand an den Ski heran und entlang der Sohle und den meist gekrümmten Seitenflanken geführt. Um eine optimale Oberfläche der Bearbeitungswerkzeuge beibehalten zu können, werden diese mit einem Abziehelement, zum Beispiel mit einem Diamanten, der am Maschinenrahmen geführt befestigt ist, in zeitlich wählbaren Abständen neu abgezogen oder/und es werden Muster auf den Schleifscheiben erzeugt, um entsprechende Schliffe bzw. Strukturen auf den Laufflächen der Skier zu erhalten. Das Abziehelement wird vorzugsweise aus einer durchgehenden Bohrung mit Kühlwasser beaufschlagt und so der Verschleiss und die Wäremeentwicklung verringert. Im Bereich des unteren Scheitels der Schleifscheiben werden diese mit einem exakt auf die Schleifscheibenoberflächen gerichteten Wasserstrahl gereinigt, d.h. es wird der Schleifstaub und allfälliger Ausbruch kontinuierlich aus den Schleifscheiben entfernt, bevor letztere wieder in Kontakt mit dem Ski gelangt. Um Fehler durch Unwucht, insbesondere der Gleitflächen- und Struktur-Schleifscheibe, mit welcher der Belag bearbeitet wird, zu vermeiden, können Mittel zum Erkennen und/oder zum Beheben der Unwucht vorgesehen sein.It succeeds by holding a ski with downwardly directed tread or sole in the center of a machine frame and a processing tools receiving car that passes under the held ski to edit the processing in very tight and thus bela gentle tolerances. The ski is constantly supported on a variety of support rollers and retains during machining the necessary planar alignment. With the support rollers that can be moved in the machine frame, they can support the ski in very short mutual distances, thereby avoiding deflections of the ski when pressing the machining tools. The positioning The ski in the machine frame is carried out on partly fixed and partly moving carrying rollers, so that the ski is always aligned exactly when the processing tools are passed under the ski. The processing tools are guided by distance sensors at a set distance to the ski and along the sole and the most curved side edges. In order to be able to maintain an optimum surface of the processing tools, they are removed with a peeling element, for example with a diamond, which is fixed to the machine frame, retired at timed intervals or / and patterns are generated on the grinding wheels to corresponding cuts or To get structures on the treads of the skis. The stripping element is preferably acted upon by a through-bore with cooling water and thus reduces the wear and the Wäremeentwicklung. In the area of the lower apex of the grinding wheels, they are cleaned with a water jet directed precisely onto the grinding wheel surfaces, ie the grinding dust and possible eruption are continuously removed from the grinding wheels before the latter comes into contact with the ski again. To avoid errors due to imbalance, In particular, the Gleitflächen- and structure-grinding wheel with which the coating is processed to avoid, can be provided for detecting and / or fixing the imbalance.

In den Figuren ist mit Bezugszeichen 1 eine Anlage zur Bearbeitung von Laufflächen an Skiern und Snowboards, kurz Skiern 5, dargestellt. Die Anlage 1 umfasst einen Maschinenrahmen 3, der mit Rahmenstützen 7 auf dem Boden des Raums abgestützt ist. Im zentralen Teil des einen rechteckigen Querschnitt aufweisenden Maschinenrahmens 3 sind nach unten wirkende pneumatische oder hydraulische Presszylinder 9 an einem geeignet ausgebildeten Sockel 11 angeordnet. Die Presszylinder 9 dienen dazu, den Ski 5 auf unter diesem liegende Tragrollen 13 zu drücken und zwar derart, dass der Ski 5 bzw. dessen Sohle 21 aus seiner bombierten Gestalt in eine gestreckte, absolut lineare Lage gedrückt wird. Die Tragrollen 13 sind auf Drehwellen an Ständern 15 frei drehbar gelagert. Die Ständer 15 weisen an ihren unteren Enden eine Verbreiterung 15' auf, an der paarweise Laufrollen 16 gelagert sind, die auf zwei parallel verlaufenden Schienen 18 im Maschinenrahmen 3 geführt werden. Im Bereich der Schienen 18 verläuft ein Band oder Zahnriemen 17. Die einzelnen Ständer 15 mit den darüber gelagerten Tragrollen 13 sind mit geeigneten Klemmmechanismen 20 mit den Zahnriemen 17 verbind- und wieder lösbar ausgebildet.
Ebenfalls, jedoch fest verbunden mit dem Zahnriemen 17, ist ein Wagen 19 angeordnet, auf welchem die Bearbeitungswerkzeuge für die Bearbeitung der Sohle 21 und der Kanten 23 des eingespannten Skis 5 angeordnet sind.In the figures, reference numeral 1 denotes a system for processing running surfaces on skis and snowboards, in short skis 5. The plant 1 comprises a machine frame 3, which is supported by frame supports 7 on the floor of the room. In the central part of the machine frame 3 having a rectangular cross-section, downwardly acting pneumatic or hydraulic press cylinders 9 are arranged on a suitably formed base 11. The press cylinders 9 serve to press the ski 5 on lying below this support rollers 13 in such a way that the ski 5 and its sole 21 is pressed from its cambered shape in an extended, absolutely linear position. The support rollers 13 are mounted on rotary shafts on stands 15 freely rotatable. The stands 15 have at their lower ends a widening 15 ', are mounted on the paired rollers 16, which are guided on two parallel rails 18 in the machine frame 3. In the region of the rails 18 extends a belt or toothed belt 17. The individual stand 15 with the support rollers 13 mounted above are connected with suitable clamping mechanisms 20 with the toothed belt 17 and again detachably formed.
Also, but firmly connected to the toothed belt 17, a carriage 19 is arranged, on which the machining tools for machining the sole 21 and the edges 23 of the clamped ski 5 are arranged.

In Figur 2 auf der rechten Seite des Wagens 19 sind z.B. zwei weitere Ständer 15 mit Tragrollen 13 angeordnet und - im Gegensatz zu den beiden Ständern 15 mit Tragrollen 13 auf der linken Seite - sind diese auf der rechten Seite des Wagens 19 zusammengeschoben.
Auch an am Wagen 19 sind Tragrollen 13 befestigt und somit mit dem Wagen 19 verfahrbar. Der Wagen 19 wird getragen von Rollen (nicht dargestellt), die z.B. auf den gleichen Schienen 18 abwälzen wie die Ständer 15 für die Tragrollen 13. Auch die beiden auf der linken Seite des Wagens 19 befindlichen Ständer 15 sind mit Klemmmitteln 20 versehen, mit denen eine temporäre Verbindung zum Zahnriemen 17 herstellbar ist. Die Ansteuerung der Klemmmittel 20 erfolgt über flexible Steuer- und Stromkabel.In FIG. 2 on the right side of the carriage 19, for example, two more uprights 15 are arranged with support rollers 13 and - in contrast to the two uprights 15 with support rollers 13 on the left side - these are pushed together on the right side of the carriage 19.
Also on the carriage 19 support rollers 13 are fixed and thus moved with the carriage 19. The carriage 19 is supported by rollers (not shown), for example, roll on the same rails 18 as the stand 15 for the support rollers 13. The two located on the left side of the carriage 19 stand 15 are provided with clamping means 20, with which a temporary connection to the toothed belt 17 can be produced. The control of the clamping means 20 via flexible control and power cables.

Auf dem Wagen 19 ist auf der linken Seite eine Gleitflächen- und Struktur-Schleifscheibe 25 mit einem Antriebsmotor angeordnet. Auf der rechten Seite des Wagens 19 sind an fliegenden Wellen mit je einem Antriebsmotor Tuning-Schleifscheiben 27 angeordnet. Zwischen der Gleitflächen- und Struktur-Schleifscheibe 25 und der Tuning-Schleifscheibe 27 sind wiederum an antreibbaren Wellenstummeln Topfschleifscheiben 29 am Wagen 19 befestigt.
Die Gleitflächen- und Struktur-Schleifscheibe 25 und die Tuning-Schleifscheiben 27 sind höhenverstellbar gelagert und können mit einer vorgebbaren Kraft an die Sohle 21 bzw. die Kanten 23 des Skis 5 herangefahren und angepresst werden. Die beiden Tuning-Schleifscheiben 27 können zudem in axialer Richtung in eine optimale Position verfahren werden, um den gesamten Verlauf der Kanten 23, der bei modernen Skiern 5 bekanntlich nicht linear, sondern bogenförmig ist, abdecken zu können. Dasselbe gilt für die beiden Topfschleifscheiben 29, welche gleichzeitig an die Aussenkanten, d.h. im Wesentlichen rechtwinklig zur Sohle 21 verlaufenden Kanten 23 heranführbar und pneumatisch anpressbar sind. Im Weiteren können die Drehachsen der Tuning-Schleifscheiben 27 aus der Horizontalen in einen spitzen Winkel geschwenkt werden. Dies ermöglicht es, den Winkel zwischen der unteren Kantenfläche in der Sohlenebene zu den seitlichen Flächen der Kanten 23 zu verändern.On the carriage 19, a Gleitflächen- and structure grinding wheel 25 is arranged with a drive motor on the left side. On the right side of the carriage 19 tuning wheels 27 are arranged on flying shafts, each with a drive motor. Between the sliding surface and structure grinding wheel 25 and the tuning grinding wheel 27 cup grinding wheels 29 are in turn attached to the carriage 19 on drivable stub shafts.
The Gleitflächen- and structure grinding wheel 25 and the tuning grinding wheels 27 are mounted vertically adjustable and can be approached and pressed with a predetermined force to the sole 21 and the edges 23 of the ski 5. The two tuning grinding wheels 27 can also be moved in the axial direction in an optimal position in order to cover the entire course of the edges 23, which is not linear, but arcuate in modern skis 5 is known. The same applies to the two cup wheels 29, which at the same time to the outer edges, ie substantially perpendicular to the sole 21 extending edges 23 can be moved and pneumatically pressed. In addition, the axes of rotation of the tuning grinding wheels 27 can be pivoted from the horizontal to an acute angle. This makes it possible to change the angle between the lower edge surface in the sole plane to the side surfaces of the edges 23.

Mit einer programmierbaren Steuerung können die Funktionen der verschiedenen Schleifscheiben 25, 27 und 29 sowie deren Höhen- bzw. Seitenlagen bei der Bearbeitung eines Skis 5 einzeln oder gemeinsam gesteuert werden. Das seitliche Zufahren der quer zum Ski 5 erfolgt gesteuert durch Distanzsensoren, so dass die Kontur des Skis 5 nicht bekannt sein muss, sondern jeder beliebige Ski 5, auch Neukreationen, in der Anlage 1 bearbeitet werden können. Vereinfacht wird diese Möglichkeit auch dadurch, dass die Spitze 31 des Skis 5 stets an einer festgelegten Stelle liegt, die beispielsweise durch eine bogenförmige Aufnahme 33 gebildet wird (vgl. Figur 3).With a programmable controller, the functions of the various grinding wheels 25, 27 and 29 and their height or lateral positions in the processing of a ski 5 can be controlled individually or jointly. The lateral approach of the transverse to the ski 5 is controlled by distance sensors, so that the contour of the ski 5 does not have to be known, but any ski 5, including new creations, can be edited in the system 1. Simplified this possibility is also characterized in that the tip 31 of the ski 5 always at a specified location is formed, for example, by an arcuate receptacle 33 (see. FIG. 3 ).

Zur Pflege bzw. Wartung der Oberflächen der Schleifscheiben 25, 27 und 29 kann am Maschinenrahmen 3 mindestens ein Abrichtelement, z.B. ein Diamant 35, auf einer Abrichtvorrichtung 36 angeordnet sein, der sich einerseits von oben auf den Mantel der Gleitflächen- und Struktur-Schleifscheibe 25 und die Mäntel der Tuning-Schleifscheiben 27 absenken und parallel zu deren Drehachsen oder der Oberflächen verschieben lässt. In einer besonders vorteilhaften Ausgestaltung der Abrichtvorrichtung 36, weisen die Diamanten 35 zur schneidenden Spitze hin mindestens eine Bohrung zum Hindurchführen von Kühlwasser auf. Damit wird einerseits eine optimale Kühlung des Diamanten 35 erreicht und andererseits dessen Standzeit vergrössert. Mit dem Diamanten 35 können nicht nur im gewünschten Winkel liegende und glatte Oberflächen an den Schleifscheiben erzeugt werden, sondern es können auch Rillen in den Oberflächen der Schleifscheiben eingelassen werden, welche ein spezielles Schleifbild auf der Sohle 21 des bearbeiteten Skis 5 erzeugen.For maintenance of the surfaces of the grinding wheels 25, 27 and 29, at least one dressing element, e.g. a diamond 35 may be disposed on a dressing device 36 which, on the one hand, can be lowered from above onto the mantle of the sliding surface and structure grinding wheel 25 and the shells of the tuning grinding wheels 27 and displaced parallel to their axes of rotation or surfaces. In a particularly advantageous embodiment of the dressing device 36, the diamonds 35 have at least one bore for the passage of cooling water towards the cutting tip. Thus, on the one hand, optimum cooling of the diamond 35 is achieved and, on the other hand, its service life is increased. With the diamond 35 not only can be produced at the desired angle and smooth surfaces on the grinding wheels, but it can also be recessed grooves in the surfaces of the grinding wheels, which produce a special grinding pattern on the sole 21 of the machined ski 5.

Im Bereich der unteren Scheitel Su der Schleifscheiben können Düsen 37 zum Hindurchführen von Wasser zur Reinigung der Schleifscheibenoberflächen angeordnet sein. Die Düsen 37 sind direkt und in geeignetem Winkel zu den Mantelflächen der Schleifscheiben ausgerichtet, derart, dass Schleifstaub und Ausbruch aus deren Oberfläche entfernt werden kann. Bei jeder Drehung der Schleifscheiben wird diese folglich gereinigt und ist sauber und nicht zugesetzt, so dass der Schleifeffekt stets gleichbleibend ist.In the area of the lower peaks S u of the grinding wheels, nozzles 37 for passing water for cleaning the surfaces of the grinding wheels can be arranged. The nozzles 37 are aligned directly and at a suitable angle to the lateral surfaces of the grinding wheels, so that grinding dust and eruption can be removed from the surface thereof. With each rotation of the grinding wheels, this is consequently cleaned and is clean and not added, so that the grinding effect is always constant.

Nachfolgend wird die Funktionsweise der Anlage 1 kurz erläutert.
Nach dem Auflegen eines Skis 5 auf die rechts des Wagens 19 befindlichen Tragrollen 13 und dem Heranschieben der Skispitze 31 an die Aufnahme 33 wird der Ski 5 durch die Presszylinder 9 von oben auf die Tragrollen 13 gepresst und dadurch deren Sohle 21 plan ausgerichtet ist. Der Ski 5 wird dadurch in seiner eingespannten Position festgehalten.
Anschliessend beginnt der Wagen 19 aus seiner Parkstellung (linke Seite im Maschinenrahmen 3) nach rechts zu fahren. Er wird dabei durch den seitlich angeordneten Zahnriemen 17 spielfrei geführt. Als erstes gelangt die Gleitflächen-und Struktur-Schleifscheibe 25 in Kontakt im Bereich der Spitze des Skis 5 mit der Sohle 21 und wird von den nicht dargestellten Anpressmitteln mit vorgegebener und geregelter Anpresskraft an die Sohle 21 angepresst. Die beiden anderen Schleifscheiben 29 und 27 sind bei diesem ersten Durchgang, bei dem der Wagen 19 aus seiner linken Position in eine rechte Position fährt, nicht in Kontakt mit dem Ski 5.
Beim Fahren des Wagens 19 gelangt auch die links von der Tuning-Schleifscheibe 27 liegende Tragrolle 13 unter den Ski 5 und stützt diesen. Bei der weiteren Bewegung nach rechts gelangen auch die übrigen Tragrollen 13 am Wagen 19 und diejenigen links des Wagens 19 unter die Sohle 21 des Skis 5 und die beiden zu Beginn den Ski 5 tragenden Tragrollen 13 (rechts vom Wagen 19) verlassen nach rechts die Sohle 21 des Skis 5 und werden zusammengestossen. Während sich der Wagen 19 zur rechten Seite bewegt, werden die beiden zuvor auf der linken Seite des Wagens 19 angeordneten eng nebeneinanderliegenden Tragrollen 13 mit den Zahnriemen 17 gekoppelt und mitgeschleppt und an vorgegebenen Positionen wieder abgekoppelt, um den Ski 5 auch in der jetzigen Position zu stützen. Während eines Arbeitsdurchgangs des Wagens 19 von links nach rechts wird der Ski folglich dauernd von mehreren Rollen 13 gestützt, jedoch nicht immer von den gleichen Tragrollen 13.The operation of Appendix 1 will be briefly explained below.
After placing a ski 5 on the right of the carriage 19 located carrying rollers 13 and the pushing of the ski tip 31 to the receptacle 33 of the ski 5 is pressed by the press cylinder 9 from above on the support rollers 13 and thereby the sole 21 is aligned plan. The ski 5 is thereby held in its clamped position.
Subsequently, the carriage 19 starts from its parking position (left side in the machine frame 3) to drive to the right. He is guided by the laterally arranged toothed belt 17 play. First, the sliding surface and structure grinding wheel 25 comes into contact in the region of the tip of the ski 5 with the sole 21 and is pressed against the sole 21 by the pressing means, not shown, with predetermined and regulated contact pressure. The other two grinding wheels 29 and 27 are in this first passage, in which the carriage 19 from its left Position moves to a right position, not in contact with the ski 5.
When driving the carriage 19 and the left of the tuning grinding wheel 27 lying support roller 13 passes under the ski 5 and supports it. In the further movement to the right, the other carrying rollers 13 on the carriage 19 and those left of the carriage 19 under the sole 21 of the ski 5 and the two at the beginning of the ski 5 carrying idlers 13 (right of the car 19) leave the sole to the right 21 of the ski 5 and are collided. While the carriage 19 moves to the right side, the two previously arranged on the left side of the carriage 19 closely adjacent support rollers 13 are coupled to the timing belt 17 and entrained and decoupled at predetermined positions to the ski 5 also in the current position support. During a working passage of the carriage 19 from left to right, therefore, the ski is constantly supported by a plurality of rollers 13, but not always by the same carrying rollers 13.

Bei der Rückkehr des Wagens 19 von seiner Position auf der rechten Seite kommen die beiden Schleifscheiben 29 und 27, d.h. die Tuning-Schleifscheibe 27, welche die Kantenunterseite bearbeitet, und die Topfschleifscheibe 29, welche die Kantenaussenfläche bearbeitet, in Eingriff, nachdem zuvor durch die Steuerung bzw. die Sensoren die Schleifscheiben in die richtige Position gebracht haben. Selbstverständlich kann - falls notwendig - auch die Gleitflächen- und Struktur-Schleifscheibe 25 beim Zurückfahren wiederum die Sohle 21 bearbeiten. Beim Zurückfahren werden wie zuvor die Tragrollen 13 auf der linken Seite nun die Tragrollen 13 auf der rechten Seite des Wagens 19 durch die Klemmelemente 20 mit dem Zahnriemen 17 verbunden, so dass der Ski 5 stets und in etwa gleichbleibenden Abständen von unten gestützt ist, derart, dass die vertikale Lage der Sohle 21 des Skis 5 stets exakt in der räumlich gleichen Stellung verharrt. Selbstverständlich können durch Distanzsensoren die Lagen der Tragrollen 13 derart bezüglich des Skis 5 eingestellt werden, dass unabhängig von der Länge des Skis letzterer stets in regelmässigen Abständen unterstützt wird.Upon the return of the carriage 19 from its position on the right side, the two grinding wheels 29 and 27, ie the tuning grinding wheel 27, which processes the edge bottom side, and the cup grinding wheel 29, which processes the edge outer surface, come into engagement, after having passed through the Control or the sensors have brought the grinding wheels in the correct position. Of course, if necessary, the sliding surface and structure grinding wheel 25 can also process the sole 21 when returning. When driving back as before, the support rollers 13 on the left side now the support rollers 13 on the right side of the carriage 19 connected by the clamping elements 20 with the toothed belt 17, so that the ski 5 is always and at approximately constant intervals supported from below, so in that the vertical position of the sole 21 of the ski 5 always remains exactly in the same spatial position. Of course, by distance sensors, the positions of the support rollers 13 can be adjusted with respect to the ski 5 that regardless of the length of the ski the latter is always supported at regular intervals.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung können in den seitlichen Lagern, insbesondere der Gleitflächen- und Struktur-Schleifscheibe 25, Mittel 39 angeordnet sein, um eine Unwucht festzustellen, die durch Abnutzung der Schleifscheibe 25 auftreten kann. Nach dem Feststellen einer Unwucht können entweder Auswuchtgewichte an geeigneter Stelle der Schleifscheibe 25 angebracht werden oder bereits montierte Auswuchtgewichte entsprechend verschoben und neu fixiert werden.In a further advantageous embodiment of the invention means 39 can be arranged in the lateral bearings, in particular the sliding surface and structure grinding wheel 25, to detect an imbalance which can occur due to wear of the grinding wheel 25. After detecting an imbalance either balancing weights can be attached to a suitable location of the grinding wheel 25 or already mounted balancing weights moved accordingly and fixed again.

Die Notwendigkeit einer Abrichtung der Oberflächen der Schleifscheiben kann in festen zeitlichen Abständen, in Abhängigkeit der Anzahl der bearbeiteten Skier 5 oder über Sensoren ausgelöst werden, welche Unregelmässigkeiten feststellen.The need for dressing the surfaces of the grinding wheels can be triggered at fixed time intervals, depending on the number of processed skis 5 or sensors that detect irregularities.

Am Wagen 19 können - falls erwünscht - auch zusätzlich zu den Schleifscheiben Prägevorrichtungen angeordnet werden, welche in die Sohle 21 des Skis 5 geeignete Strukturen einprägen. Dies kann mit geheizten Prägewalzen oder durch Heizen und nachfolgendes Prägen der erweichten Oberfläche erfolgen.On the carriage 19 can - if desired - also in addition to the grinding wheels embossing devices are arranged, which impress appropriate structures in the sole 21 of the ski 5. This can be done with heated embossing rolls or by heating and subsequent embossing of the softened surface.
