Description

Die Erfindung betrifft einen Schleifband-Speicher, bei dem mindestens eine durch gewickeltes Schleifmittelband gebil­dete, eine zentrale Durchgangsöffnung aufweisende Band­rolle in ihrer Durchgangsöffnung mindestens einen Lager­einsatz aufweist, der mit einer zur Rollenachse etwa koaxialen Drehlagerfläche zur drehbaren Lagerung der Bandrolle an einem Traglager versehen ist.The invention relates to an abrasive belt storage device in which at least one belt roll formed by a wound abrasive belt and having a central through opening has at least one bearing insert in its through opening, which is provided with a rotary bearing surface approximately coaxial with the roll axis for rotatably mounting the belt roll on a support bearing.

Derartige, in Rollenform gespeicherte Schleifbänder können dadurch zum Abziehen des Schleifmittelbandes drehbar gelagert und bereitgehalten werden, daß durch die Durch­gangsöffnung der Bandrolle eine beispielsweise aufgehängte Stange gesteckt wird, die ggf. die Bandrolle über eine Innenumfangsfläche des jeweiligen Lagereinsatzes drehbar abstützt. Die Lagerstange hat gegenüber der die Drehlager­fläche bildenden Innenumfangsfläche in der Regel ein verhältnismäßig großes Lagerspiel, so daß einerseits eine ziemlich ungenaue, pendelnde Lagerung der Bandrolle gege­ ben ist und andererseits die Gleitreibung der Drehlagerung so gering ist, daß die Bandrolle nach Beendigung der Zugbelastung des ablaufenden Bandendes beim Abziehen eines abzulängenden Schleifmittelband-Abschnittes noch um einen verhältnismäßig großen Drehwinkel nachläuft, was zu einem unerwünschten Abwickeln der Bandrolle führt.Such abrasive belts stored in roll form can be rotatably supported and kept ready for pulling off the abrasive belt in that a rod, for example a suspended rod, is inserted through the passage opening of the belt roll, which, if necessary, rotatably supports the belt roll over an inner peripheral surface of the respective bearing insert. The bearing rod has a relatively large bearing play compared to the inner circumferential surface forming the pivot bearing surface, so that on the one hand a rather imprecise, oscillating mounting of the tape reel ben is and on the other hand, the sliding friction of the rotary bearing is so low that the tape reel after completion of the tensile load of the end of the tape when pulling a section of abrasive tape to be cut still runs by a relatively large angle of rotation, which leads to an unwanted unwinding of the tape reel.

Der Erfindung liegt die Aufgabe zugrunde, einen Schleif­band-Speicher der genannten Art so auszubilden, daß auf einfache Weise eine exakte und gut gebremste Lagerung der Bandrolle möglich ist.The invention has for its object to design an abrasive belt storage of the type mentioned so that an exact and well braked storage of the tape roll is possible in a simple manner.

Dies wird bei einem Schleifband-Speicher der eingangs beschriebenen Art erfindungsgemäß dadurch erreicht, daß die Drehlagerfläche durch eine Außenumfangsfläche gebildet ist. Dadurch kann die Bandrolle auf verhältnismäßig großem Umfang der Drehlagerfläche und damit mit verhältnismäßig großer Reibung, d.h. zur Sicherung gegen Nachlaufen ausreichend gebremst, gelagert werden. Weiterhin kann zur Lagerung der Bandrolle auf das umständliche Einstecken einer Stange verzichtet werden, da es durch die Ausbildung der Drehlagerfläche als Außenumfangsfläche ohne weiteres möglich ist, die Bandrolle lediglich durch Auflegen zu lagern.This is achieved according to the invention in an abrasive belt store of the type described in the introduction in that the rotary bearing surface is formed by an outer peripheral surface. As a result, the tape roll can on a relatively large circumference of the pivot bearing surface and thus with a relatively large amount of friction, i.e. adequately braked and stored to protect against overrun Furthermore, the laborious insertion of a rod can be dispensed with for the storage of the tape reel, since it is readily possible to design the swivel bearing surface as the outer circumferential surface to support the tape reel simply by laying it on.

Die erfindungsgemäße Gestaltung der Drehlagerfläche ge­währleistet einen geringen, über die Außenbegrenzungen des Schleifmittelbandes hinausragenden Raumbedarf der Lager­einsätze, so daß die Bandrolle durch diese Lagereinsätze nur unwesentlich verbreitert wird.The design of the pivot bearing surface according to the invention ensures a small space requirement of the bearing inserts which projects beyond the outer limits of the abrasive belt, so that the belt reel is only insignificantly widened by these bearing inserts.

Obwohl es denkbar ist, den Schleifmittel-Speicher aus­schließlich durch die gewickelte Bandrolle in Verbindung mit einem oder zwei Lagereinsätzen zu bilden, ist es besonders vorteilhaft, wenn der Schleifmittel-Speicher zusätzlich ein an die Bandrolle bzw. die Lagereinsätze angepaßtes Traglager zur leicht herausnehmbaren bzw. einsetzbaren Aufnahme der Bandrolle aufweist. Dieses Traglager kann gemäß der Erfindung in einfacher Weise so ausgebildet werden, daß benachbarte Bandrollen einander beim Drehen nicht berühren und damit auch nicht in Ab­wickelrichtung mitnehmen, ohne daß hierfür ein ins Gewicht fallender zusätzlicher Raumbedarf erforderlich ist. Dieses Traglager weist zweckmäßig Lagerschalen für die Aufnahme der Drehlagerflächen auf, wobei der Radius der Lager­schalen so an den Durchmesser der Drehlagerflächen ange­paßt werden kann, daß bei exakter Lagerung die gewünschte Bremswirkung auftritt. Das Traglager kann in einfacher Weise für die Aufnahme zweier oder mehrerer, vorzugsweise achsgleich nebeneinander mit horizontaler Achse liegender Bandrollen vorgesehen sein, so daß Schleifmittelband unterschiedlicher Körnung nebeneinanderliegend bereitge­halten werden kann.Although it is conceivable to connect the abrasive storage exclusively through the wound reel To form with one or two bearing inserts, it is particularly advantageous if the abrasive storage additionally has a support bearing adapted to the band reel or the bearing inserts for easily removable or insertable reception of the band reel. This support bearing can be designed in a simple manner according to the invention in such a way that adjacent tape rolls do not touch each other when rotating and thus do not take them along in the unwinding direction, without requiring a significant additional space requirement. This support bearing expediently has bearing shells for receiving the pivot bearing surfaces, the radius of the bearing shells being able to be adapted to the diameter of the pivot bearing surfaces in such a way that the desired braking effect occurs when the bearing is exact. The support bearing can be provided in a simple manner for the reception of two or more, preferably coaxially adjacent to each other with a horizontal axis tape rolls, so that abrasive tape of different grain size can be kept next to each other.

Ferner können gemäß der Erfindung Mittel zum einfachen Abtrennen des jeweils von einer Bandrolle abgezogenen Teiles des Schleifmittelbandes vorgesehen sein, wobei diese Abtrennvorrichtung zweckmäßig so angeordnet ist, daß sie bei jedem Rollendurchmesser im wesentlichen gleich gut wirkt.Furthermore, according to the invention, means can be provided for the simple cutting off of the part of the abrasive belt which is in each case pulled off a roll of tape, this separating device being expediently arranged in such a way that it works essentially equally well with each roll diameter.

Diese und weitere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen auch aus der Beschreibung und den Zeichnungen hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombina­tionen bei einer Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein können. Ein Ausfüh­rungsbeispiel der Erfindung ist in den Zeichnungen darge­stellt und wird im folgenden näher erläutert. In den Zeichnungen zeigen:

These and further features of preferred developments of the invention also emerge from the description and the drawings, the individual features each individually or in groups in the form of sub-combinations in one embodiment of the invention and on other areas can be realized. An embodiment of the invention is shown in the drawings and is explained in more detail below. The drawings show:
  • 1 shows an inventive abrasive belt storage, partly in axial section,
  • 2 shows a bearing insert of the sanding belt store according to FIG. 1 in a partially sectioned view of the outside,
  • 3 is a support bearing for several abrasive tape rolls of the abrasive tape storage,

Der in Fig. 1 dargestellte, durch eine einzige Bandrolle 2 aus gewickeltem Schleifmittelband konstanter Breite gebil­dete Schleifband-Speicher 1, der auch zwei oder mehr Bandrollen und zusätzlich ein Traglager 3 gemäß den Figuren 3 bis 5 aufweisen kann, weist im Zentrum der Bandrolle 2 eine durch einen Wickelkern bestimmte, im wesentlichen zylindrische Durchgangsöffnung 4 auf, in die von beiden Stirnseiten 5 her zwei jeweils einteilige, gleich ausgebildete Lagereinsätze 6 derart eingesteckt sind, daß sie im Abstand voneinander liegen und aus­schließlich durch Verspannung gegenüber der Bandrolle 2 unabhängig voneinander an dieser gehalten sind. Jeder Lagereinsatz.6 weist einen als hülsenförmigen Rotations­ körper ausgebildeten, zu seinem inneren Ende schwach konisch verjüngten Kernteil 7 mit gegenüber seinem Außen­durchmesser wesentlich kleinerer Axialerstreckung auf, der zur besseren Sicherung gegenüber der Innenfläche der Durchgangsöffnung 4 am Außenumfang mit Erhebungen, bei­spielsweise mit axialrippenartigen Vorsprüngen versehen sein kann. Unmittelbar im Anschluß an den größten Durch­messer des Kernteiles 7 sind zwei im Abstand voneinander­liegende, radial nach außen um ein möglichst geringes Maß vorstehende Ringbunde 8, 9 vorgesehen, die zwischen sich eine im Querschnitt annähernd rechteckige bzw. quadra­tische Ringnut von einer Breite im Millimeterbereich begrenzen. Der innere Ringbund 8 dient als Anschlag zur axialen Ausrichtung des Lagereinsatzes 6 gegenüber der zugehörigen Stirnfläche 5 der Bandrolle 2; dieser An­schlag kann auch durch einzelne, über den Umfang verteilte Vorsprünge gebildet sein oder ganz weggelassen werden, so daß der Lagereinsatz 6 lediglich durch mehr oder weniger tiefes Einschieben in die Durchgangsöffnung 4 axial gegen­über der Bandrolle 2 ausgerichtet wird. Der äußere Ring­bund 9, der am äußeren Ende des als Stirndeckel bzw. Lagerschild dienenden Lagereinsatzes 6 liegt, begrenzt axial eine durch eine Rotationsfläche bzw. den Nutgrund der Ringnut gebildete Drehlagerfläche 10 an ihrem der zugehörigen Stirnfläche 5 gegenüberliegenden Ende. Koaxial in der napfförmigen, jedoch im Boden mit Durchbrüchen versehenen Außenmuffe weist der Lagereinsatz eine von Radialrippen getragene zylindrische Nabenhülse 11 auf, durch welche ein Traglager in Form einer Stange oder dgl. gesteckt werden kann. Die Bandrolle 2 kann mit der Dreh­lagerfläche 10 oder mit die Außenumfangsfläche mindestens eines Ringbundes 8 bzw. 9 so in vertiefte Kuhlen zweier seitlicher, in Fig. 1 strichpunktiert angedeuteter Lager­ wangen 13 eines Traglagers von oben eingelegt werden, daß sie einerseits durch Ziehen am ablaufenden Bandende 14 gedreht werden kann und andererseits dieser Drehung durch Reibung eine verhältnismäßig große Bremskraft entgegen­wirkt, so daß die Bandrolle 2 nach Aufheben des Zuges am ablaufenden Bandende 14 nicht nachläuft, sondern sofort stillsteht.The abrasive belt store 1 shown in FIG. 1, formed by a single belt roll 2 made of wound abrasive belt of constant width, which can also have two or more belt rolls and additionally a support bearing 3 according to FIGS. 3 to 5, has one in the center of the belt roll 2 determined by a winding core, essentially cylindrical through-opening 4, into which two one-piece, identically designed bearing inserts 6 are inserted from both end faces 5 in such a way that they are at a distance from one another and are held independently of one another only by tensioning them against the tape roll 2 are. Each bearing insert.6 has one as a sleeve-shaped rotation body-shaped, to its inner end slightly tapered core part 7 with its outer diameter much smaller axial extent, which can be provided with bumps, for example with axial rib-like projections, for better securing against the inner surface of the through opening 4 on the outer circumference. Immediately following the largest diameter of the core part 7, two ring bundles 8, 9 which are spaced apart and project radially outward by as small a dimension as possible, which between them delimit an approximately rectangular or square ring groove with a width in the millimeter range. The inner collar 8 serves as a stop for the axial alignment of the bearing insert 6 with respect to the associated end face 5 of the tape roll 2; this stop can also be formed by individual projections distributed over the circumference or can be omitted entirely, so that the bearing insert 6 is aligned axially with respect to the tape roll 2 only by more or less deep insertion into the through opening 4. The outer annular collar 9, which lies at the outer end of the bearing insert 6 serving as an end cover or end shield, axially delimits a rotary bearing surface 10 formed by a rotating surface or the groove base of the annular groove at its end opposite the associated end face 5. Coaxially in the cup-shaped outer sleeve, but provided with openings in the bottom, the bearing insert has a cylindrical hub sleeve 11 supported by radial ribs, through which a support bearing in the form of a rod or the like can be inserted. The tape roll 2 can with the pivot bearing surface 10 or with the outer circumferential surface of at least one annular collar 8 or 9 in recessed cavities of two lateral bearings, indicated by dash-dotted lines in FIG. 1 cheeks 13 of a support bearing are inserted from above, that on the one hand they can be rotated by pulling on the running end of the band 14 and on the other hand this rotation counteracts a relatively large braking force by friction, so that the band reel 2 does not run on the running end of the band 14 after lifting the train, but instead immediately stops.

Die als stirnseitige Lagerabstützungen vorgesehenen Lager­wangen 13 sind zweckmäßig in Form vertikaler Untertei­lungswände in gleichen Abständen frei vorstehend an einem Träger bzw. einer Konsole angeordnet, die durch eine plattenförmige Rückwand 15 aus Blech gebildet sein kann und an beiden Seiten nach hinten abgesetzte Winkelflansche als Befestigungsglieder 16 zur Befestigung an einer Wand, an zwei hinteren Stützen eines Regalsystems oder dgl. aufweist. Im dargestellten Ausführungsbeispiel sind für die Aufnahme von vier Bandrollen fünf Lagerwangen 13 vorgesehen, von denen die beiden äußersten im Bereich der durch die Befestigungsglieder 16 gebildeten Seitenbegren­zungen des Traglagers 3 liegen. An ihren von der Rückwand 15 abgekehrten Vorderseiten sind alle Lagerwangen 13 über durchgehende Profilstäbe miteinander verbunden, so daß sich eine selbsttragende Rahmenkonstruktion von hoher Festigkeit ergibt.The bearing cheeks 13 provided as end-side bearing supports are expediently arranged in the form of vertical partition walls at the same intervals, freely protruding from a support or bracket, which can be formed by a plate-shaped rear wall 15 made of sheet metal and offset angle flanges on both sides as fastening members 16 Attachment to a wall, on two rear supports of a shelving system or the like. In the exemplary embodiment shown, five bearing cheeks 13 are provided for accommodating four tape rolls, the two outermost of which lie in the region of the side boundaries of the support bearing 3 formed by the fastening members 16. On their front sides facing away from the rear wall 15, all bearing cheeks 13 are connected to one another via continuous profiled bars, so that a self-supporting frame construction of high strength results.

Zumindest jede der zwischen den äußersten Lagerwangen 13 liegenden Lagerwangen weist an ihrer Oberseite zwei mit­einander fluchtende, unmittelbar nebeneinanderliegende Lagerschalen 17 auf, deren Abstand von der Rückwand 15 größer als von der Vorderseite des Traglagers ist. Der Abstand zwischen den beiden Lagerschalen 17 einer Lager­wange 13 ist nur geringfügig größer als die doppelte Dicke eines Ringbundes 9 der Lagereinsätze 6, so daß benachbarte Lagereinsätze 6 zweier benachbarter Bandrollen 2 mit ihren einander zugekehrten Stirnflächen raumsparend in sehr geringem Abstand voneinander liegen können. Zur besseren Zugänglichkeit der Lagereinsätze sowie zur vereinfachten Herstellung sind alle Lagerwangen 13 gleich ausgebildet. Jede Lagerwange 13 ist durch zwei parallele, aus Blech­platten bestehende, spiegelsymmetrische Wandungen 18 gebildet, deren Abstand voneinander gleich dem Abstand zwischen ihren Lagerschalen 17 ist. Diese Wandungen 18 sind zwischen den Lagerschalen 17 und der Rückwand 15 an ihren Oberkanten und im Bereich eines vor den Lagerschalen 17 liegenden oberen, geneigten Teiles der Vorderkante der Lagerwange 13 aufeindander zu abgesetzt bzw. abgekröpft und mit diesen abgekröpften Randstreifen 19, beispielsweise durch Punktschweißung, aneinander befestigt. Oberhalb ihrer horizontalen Unterkanten können die Wandungen 18 nach innen vorspringende, beispielsweise noppenförmige Distanzvorsprünge 20 aufweisen, mit welchen sie aneinander anliegen und die ebenfalls durch Punktschweißung aneinan­der befestigt sein können. Dadurch bildet jede Lagerwange 13 einen im Bereich der Lagerschalen 17 und im Bereich seiner Unterseite entsprechend dem Abstand zwischen den Wandungen 18 offenen Hohlkammer-Bauteil von hoher Festig­keit bei geringem Gewicht. Beide Wandungen 18 der mitt­leren Lagerwangen 13 sowie die inneren Wandungen 18 der beiden äußersten Lagerwangen 13 bilden nach außen abgewin­kelte, annähernd über ihre ganze Höhe reichende Befesti­gungsschenkel 21, mit welchen die Lagerwangen 13 durch Punktschweißung oder dgl. an der Rückwand 15 befestigt sind. Die äußeren Wandungen 18 der beiden äußeren Lager­wangen 13 sind über deren hintere Enden in deren Ebene nach hinten fortgesetzt und am abgesetzten Befestigungs­ glied 16 durch Schweißung oder dgl. befestigt.At least each of the bearing cheeks lying between the outermost bearing cheeks 13 has on its upper side two bearing shells 17 which are aligned with one another and lie directly next to one another and whose distance from the rear wall 15 is greater than from the front of the supporting bearing. The distance between the two bearing shells 17 of a bearing cheek 13 is only slightly larger than twice the thickness an annular collar 9 of the bearing inserts 6, so that adjacent bearing inserts 6 of two adjacent tape rolls 2 with their mutually facing end faces can be very close to one another in a space-saving manner. For better accessibility of the bearing inserts and for simplified production, all bearing cheeks 13 are of the same design. Each bearing cheek 13 is formed by two parallel, mirror-symmetrical walls 18 consisting of sheet metal plates, the distance from one another being equal to the distance between their bearing shells 17. These walls 18 are offset or cranked between the bearing shells 17 and the rear wall 15 at their upper edges and in the region of an upper, inclined part of the front edge of the bearing cheek 13 lying in front of the bearing shells 17 and with these cranked edge strips 19, for example by spot welding, attached to each other. Above their horizontal lower edges, the walls 18 can have inwardly projecting, for example knob-shaped, spacing projections 20 with which they abut one another and which can also be fastened to one another by spot welding. As a result, each bearing cheek 13 forms a hollow chamber component which is open in the region of the bearing shells 17 and in the region of its underside in accordance with the distance between the walls 18 and is of high strength and low weight. Both walls 18 of the central bearing cheeks 13 and the inner walls 18 of the two outermost bearing cheeks 13 form outwardly angled fastening legs 21 which extend almost over their entire height and with which the bearing cheeks 13 are fastened to the rear wall 15 by spot welding or the like. The outer walls 18 of the two outer bearing cheeks 13 are continued over their rear ends in their plane to the rear and at the remote fastening member 16 fixed by welding or the like.

Jede Lagerschale 17 bildet eine teilkreisförmig, insbeson­dere höchstens halbkreisförmig begrenzte, konkave Lauf- ­und Bremsfläche 22 für den Eingriff der Drehlagerfläche 10 des zugehörigen Lagereinsatzes 6, wobei die Breite der Drehlagerfläche 6 so an die Blechdicke im Bereich der jeweiligen Lauffläche 22 angepaßt ist, daß sie in diese mit verhältnismäßig geringem Axialspiel eingreift. Der Radius der Lauffläche 22, die auch durch einzelne, im Abstand voneinanderliegende Vorsprünge gebildet sein kann, ist praktisch gleich dem halben Durchmesser der Drehlager­fläche 10, so daß über den Umfang der Lauffläche 22 eine gleichmäßige Anlage an der Drehlagerfläche 10 gewähr­leistet ist. Zur Rückseite der Lagerwange 13 geht jede Lauffläche 22 tangential in eine vertikal nach oben an­schließende Begrenzungskante 23 über, die an den zugehöri­gen Randstreifen 19 anschließt und bis etwa in eine Höhe über der tiefsten Stelle der Lauffläche 22 reicht, die gleich deren Durchmesser ist. Die zur Vorderseite hin liegende Begrenzung der Lauffläche 22 endet etwa in Höhe von deren Mittelachse 12. Dadurch kann beim Einsetzen einer Bandrolle 2 diese mit ihren Lagereinsätzen gegen die Begrenzungskanten 23 von vorne angeschlagen und dann durch Absenken in Eingriff mit den Laufflächen 22 gebracht werden.Each bearing shell 17 forms a partially circular, in particular at most semicircularly limited, concave running and braking surface 22 for the engagement of the pivot bearing surface 10 of the associated bearing insert 6, the width of the pivot bearing surface 6 being adapted to the sheet thickness in the area of the respective bearing surface 22 such that it engages in them with relatively little axial play. The radius of the tread 22, which can also be formed by individual, spaced apart projections, is practically equal to half the diameter of the pivot bearing surface 10, so that uniform contact with the pivot bearing surface 10 is ensured over the circumference of the tread 22. To the rear of the bearing cheek 13, each tread 22 merges tangentially into a vertically upward adjoining edge 23 which adjoins the associated edge strip 19 and extends approximately to a height above the lowest point of the tread 22, which is the same as its diameter. The boundary of the tread 22 lying towards the front ends approximately at the level of its central axis 12. When a tape roll 2 is inserted, it can be struck from the front with its bearing inserts against the boundary edges 23 and then brought into engagement with the treads 22 by lowering.

Die die Lagerwangen 13 an der Vorderseite im Anschluß an deren Unterkanten verbindenden, im wesentlichen durch Winkelprofile gebildeten Profilstäbe sind als Abtrennvor­richtung 24 für die ablaufenden Bandenden 14 der Band­rollen 2 ausgebildet, wobei zwei nach vorne abstehende Winkelschenkel einen über die Breite des Traglagers 3 ununterbrochen durchgehenden Abzugs- bzw. Durchlauf­schlitz 25 für die Bandenden 14 bilden, der in Abzugsrich­tung trichterartig verengt ist und unmittelbar oberhalb einer Längenmeßvorrichtung 26 liegt. Die untere, gegenüber der oberen Begrenzung zurückversetzte Längsbegrenzung des Abzugsschlitzes 25 ist zur Bildung einer Abreißkante 27 spitzwinklig gezackt bzw. gezahnt ausgebildet, so daß das Bandende 14 durch Druck nach unten gegen die Abreißkante 27 sauber abgetrennt und damit von der Bandrolle 2 gelöst werden kann. Den Befestigungsschenkeln 21 entsprechende Befestigungsschenkel 28 tragen die Profilstäbe 29, 30.The profile bars connecting the bearing cheeks 13 on the front side at the bottom edges, which are essentially formed by angle profiles, are designed as a separating device 24 for the running tape ends 14 of the tape rolls 2, two angled legs projecting forward one across the width of the support bearing 3 Continuously continuous take-off or through-slot 25 for the band ends 14, which is narrowed like a funnel in the take-off direction and lies directly above a length measuring device 26. The lower longitudinal recess of the take-off slot 25, which is set back from the upper limit, is serrated or serrated to form a tear-off edge 27, so that the band end 14 can be cleanly separated by pressure downwards against the tear-off edge 27 and can thus be detached from the tape roll 2. The fastening legs 28 corresponding fastening legs 28 carry the profile bars 29, 30.

Jeweils eine Längenmeßvorrichtung 26 ist im Bereich der zu den äußersten Lagerwangen 13 benachbarten Lagerwangen, also im Bereich jeder zweiten Lagerwange, vorgesehen, so daß die jeweilige Längenmeßvorrichtung 26 für zwei benach­barte Bandrollen 2 verwendet werden kann. Die jeweilige Längenmeßvorrichtung 26 weist einen etwa rechtwinklig zur Rückwand 15 zwischen den zugehörigen Wandungen 18 der Tragwange 13 liegenden Meßstab 31 auf, der in einem als Gleitlager dienenden Führungsbügel 32 an der Vorderseite der Lagerwange 13 in seiner Längsrichtung verschiebbar gelagert ist. Der Führungsbügel 32 ist im einspringenden Winkel des unteren Profilstabes 30 befestigt, dessen aufrechter Schenkel eine weitere, der Gleitöffnung im Führungsbügel 32 mit geringem Abstand gegenüberliegende Gleitöffnung für den Meßstab 31 aufweist, derart, daß dieser infolge seines Lagerspieles in ausgezogenem Zustand gegenüber seiner Verschieberichtung auch Querbewegungen ausführen und dadurch leicht gemeinsam mit dem Bandende 14 gehalten werden kann. Das hintere Ende des durch einen Drahtabschnitt gebildeten Meßstabes 31 ist zur Bildung eines Anschlages 33 abgewinkelt. Dieser Anschlag 33 dient durch Anlage an der Rückwand 15 sowohl zur Anschlagbegren­zung der eingeschobenen Stellung als auch durch Anschlag an dem Profilstab 30 zur Anschlagbegrenzung der ausgezoge­nen Stellung. In der eingeschobenen Stellung ragt das vordere Ende des Meßstabes 31 so weit frei über die Vorderseite des Führungsbügels 32 vor, daß es zum Herausziehen bequem gegriffen werden kann. In ausgezogenem Zustand steht der Meßstab 31 um dasjenige Maß über die Abreißkante 27 vor, welches der Länge eines Schleifmittelband-Abschnittes entspricht, wie er üblicherweise für die Verwendung an Rutschern bzw. Schwingschleifern benötigt wird. Dadurch, daß der Raum zwischen benachbarten Lagerwangen 13 von unten her frei zugänglich ist, kann das ablaufende Bandende 14 der jeweiligen Bandrolle 2 von unten her leicht gegriffen und durch den Abzugsschlitz 25 nachgeschoben werden.One length measuring device 26 is provided in the area of the bearing cheeks adjacent to the outermost bearing cheeks 13, that is to say in the area of every second bearing cheek, so that the respective length measuring device 26 can be used for two adjacent belt rolls 2. The respective length measuring device 26 has a measuring rod 31 lying approximately at right angles to the rear wall 15 between the associated walls 18 of the support cheek 13, which is slidably mounted in its longitudinal direction in a guide bracket 32 serving as a sliding bearing on the front of the support cheek 13. The guide bracket 32 is fastened at the protruding angle of the lower profile rod 30, the upright leg of which has a further slide opening for the measuring rod 31, which is opposite the sliding opening in the guide bracket 32 at a small distance, in such a way that, due to its bearing play in the extended state, it also has transverse movements with respect to its direction of displacement execute and can be easily held together with the tape end 14. The rear end of the measuring rod 31 formed by a wire section is angled to form a stop 33. This stop 33 serves by abutment on the rear wall 15 both to limit the stop of the inserted position and by abutment on the profile bar 30 to limit the stop of the extended position. In the inserted position, the front end of the measuring rod 31 projects so far freely over the front side of the guide bracket 32 that it can be gripped comfortably for pulling out. In the extended state, the measuring rod 31 projects beyond the tear-off edge 27 by the amount which corresponds to the length of an abrasive belt section as is usually required for use on sliders or orbital sanders. Characterized in that the space between adjacent bearing cheeks 13 is freely accessible from below, the running end of the tape 14 of the respective tape roll 2 can be easily gripped from below and pushed through the trigger slot 25.
