Definitions
- the invention relates to a film hand dispenser with a frame in which a film roll made of stretch film can be accommodated between two frame transverse parts running transversely to its longitudinal axis, for a rotatable mounting, a braking device acting on the film roll and an adjusting device by means of which the braking device can be regulated.
- the end of the film web is placed on the goods to be packaged and initially held there. Then the goods are first wrapped around once and then several times, whereby the film is stretched so that it sticks to the product or a film underlayer due to its restoring force.
- the wrapping can proceed in such a way that the goods are rotated in front of the film dispenser or this is guided around the goods. In any case, care must be taken to ensure that the film does not unwind loosely, but is pulled off under stretch, since otherwise it will not stick to the goods or a lower film layer. This requires a more or less strong braking of the film roll, which must also take into account the fact that the diameter of the film roll decreases continuously during the winding process.
- the frame in which the film roll is mounted has an upper cross part articulated at one end to the first longitudinal frame part, the other end of which, to a greater or lesser extent, against the upper end of the second longitudinal frame part by means of an adjusting screw is pressed, with the result that a holding member carried by the cross member and rotatably supported there is pressed more or less strongly against the upper end face of the film roll.
- the actuation of the set screw is laborious, often even impossible, since the film dispenser must generally be held with both hands and when packing higher objects it must be raised so much that the set screw cannot be reached at all can.
- the object of the invention is to remedy this, ie to provide a film hand roller in which the braking device can be moved at any time, ie even without problems can be regulated if it is necessary to wrap the upper areas of higher objects with stretch film.
- a film hand dispenser in which the actuating member for the adjustment device is formed by at least one rotatable frame part which runs essentially parallel to the longitudinal axis of the film roll.
- the adjusting device of the film dispenser according to the invention can act on its braking device, for example via a cable or a gear transmission.
- an embodiment has proven to be particularly simple to manufacture and handle, in which the adjusting device can be changed in length and the frame cross parts can be pressed in an axial direction onto the core of the film roll in a manner known per se by shortening the adjusting device.
- the latter applies in particular when the two frame transverse parts and the further longitudinal frame part connecting them are designed as spring clips, that is to say the frame is free of articulated and plug-in connections, which is the case in a preferred embodiment of the film hand dispenser according to the invention.
- an adjusting screw can be provided between it and one of the frame transverse parts, which is preferably articulated.
- the frame transverse parts which is preferably articulated.
- two articulated set screws are provided, by which one is right-handed and the other left-handed
- the rotatable frame part can be designed as a twist grip, preferably as a grip roller or square tube, and can have a length which preferably corresponds essentially to the width of the foil roller.
- the rotatable longitudinal frame part can also consist of two telescopically interacting parts, each of which is rotatably connected to one of the transverse frame parts, preferably via a joint. In any case, it has proven to be advantageous to arrange the rotatable longitudinal frame part between the free ends of the two transverse frame parts and the bearings for the film roll essentially in the middle of the transverse frame parts.
- the two cross frame parts preferably each have a centering member protruding into the inside of the film roll inside in the working position, one of the two centering members having a face resting on the front of the film roll and being rotatably mounted, while the other centering member has a front acting on the film roll Brake disc is assigned, which is rotatably mounted on a stop plate.
- the film roller bearing is preferably designed in a manner known per se as an axial thrust bearing and preferably has a bearing part which is displaceable in the axial direction relative to the associated frame cross part and can be fixed in the axial direction by means of a tensioning device.
- the tensioning device can be, for example, from a Set screw must be formed.
- a self-locking quick release device has proven to be particularly practical, since it can be operated easily and without problems, and preferably has only two end positions, namely a holding position and a release position.
- This quick clamping device can have an actuator designed as a rocker arm which is attached to an eccentric disk cooperating with an adjusting bolt under spring pressure, the end of the eccentric disk bearing the rotatably mounted film roller bearing part.
- a support foot can be provided on the frame cross part opposite the tensioning device, which enables the device to be parked on the floor.
- the support foot can be formed, for example, by a ring, the diameter of which is preferably larger than the diameter of a full film roll.
- the film hand dispenser shown has a support leg 1 formed by a metal ring, which is fastened to the lower cross part 2 of the device frame.
- the end of the cross part 2 shown on the right in each case merges into a longitudinal part 3 of the device frame, which runs at right angles thereto, at the other end of which the upper cross part 4 of the device frame connects at right angles.
- the two cross parts 2, 4 and the connecting longitudinal part 3 of the device frame are formed in one piece and are preferably made from a metal tube with a flat rectangular cross section, so that they represent a spring clip, the legs of which are formed by the cross parts 2, 4, more or less pressed apart or can be contracted.
- a small bearing plate 5 is fastened, on which a brake disc 6 is rotatably mounted.
- a centering member 7 which in the working position of the film dispenser projects into the interior of the pushed-on film roll 8, while the brake disc 6 acts on the end face of the film roll 8 or its core roll.
- a centering member 9 is also provided below the center of the upper cross frame part 4.
- This centering member 9 has a circumferential collar 10, which acts in the working position on the end face against the film roll 8 or its core roll.
- the upper centering member 9 is rotatably mounted at the lower end of an adjusting bolt 11 which is guided in a recess in the upper frame cross part 4.
- the upper end of the adjusting bolt 11 has a circumferential collar, against which a compression spring acts from below, which extends downwards supports against the upper cross member 4.
- two tabs 12, 13 are fastened to the upper cross frame part 4, between which a washer 14 is mounted.
- a rocker arm 15 is attached to the disk 14.
- the disk 14 On the side opposite the rocker arm 15, the disk 14 has a semicircular area, to which disk sides parallel to one another adjoin. In the illustrated position of the rocker arm 15, the upper end of the adjusting bolt 11 is pressed against one of these disk sides by the compression spring acting on it.
- the disc 14 is mounted eccentrically between the two tabs 12, 13 by means of a hinge pin 16, ie the distances between the two parallel disc sides to the bearing axis are of different sizes, with the result that the adjusting bolts 11 pressed against the eccentric disc 14 by spring pressure from below are put together with the centering member 9 carried by it is displaced axially upward when the rocker arm 15 together with the eccentric disk 14 rigidly connected to it is pivoted from the end position shown (holding position) to the left into the second end position (release position).
- openings 17, 18 are provided, in which one end of a set screw 19, 20 is articulated by means of a hinge pin 21, 22.
- One of these set screws 19, 20 has a left-hand thread, the other a right-hand thread.
- Both set screws are screwed into nuts, which are each fastened, preferably welded, to one end of a tube serving as a turning handle 23.
- This tube forms the second longitudinal frame part.
- An actuation of the rotary handle 23 has the consequence that the two setscrews 19, 20 are screwed more or less far into the interior of the rotary handle and this in turn that the free ends of the two frame cross parts 2, 4 are moved towards one another or away from one another to a greater or lesser extent. The latter has the result that a fine adjustment of the distance between the two centering members 7, 9 can be carried out by actuating the rotary handle 23.
- the film hand dispenser shown can be used, for example, in the following way:
- the rocker arm 15 is folded from the end position shown to the left, so that the adjusting pin 11 and thus the upper centering member 9 is displaced upward by the spring acting on the adjusting pin 11.
- a full film roll 8 can be placed on the lower centering member 7.
- the rocker arm 15 is again pivoted to the right into the end position shown, the upper centering member 9 engaging in the interior of the film roll or its core roll.
- the film roll 8 is now held by the two centering members 7, 9 and can be rotated more or less easily, the effect of the brake disk 6 interacting on the one hand with the film roll 8 and on the other hand with the bearing plate 5 on the nature of the brake disk and of that Foil roll 8 depends on the contact pressure exerted.
- the braking effect of the brake disc 6 can, however, be changed by actuating the rotary handle 23 which also serves as a handle.
- the height at which the foil dispenser is used is irrelevant, since the adjustment device of your braking device is easily accessible even in the most extreme positions.

Abstract
Description
Die Erfindung betrifft einen Folienhandabroller mit einem Rahmen, in dem eine Folienrolle aus Dehnfolie zwischen zwei quer zu deren Längsachse verlaufenden Rahmenquerteilen zur drehbaren Lagerung aufnehmbar ist, einer auf die Folienrolle einwirkenden Bremseinrichtung sowie einer Verstelleinrichtung, mittels der die Bremseinrichtung regulierbar ist.The invention relates to a film hand dispenser with a frame in which a film roll made of stretch film can be accommodated between two frame transverse parts running transversely to its longitudinal axis, for a rotatable mounting, a braking device acting on the film roll and an adjusting device by means of which the braking device can be regulated.
Derartige Geräte werden heute bereits vielfach bei der Verpackung von Waren aller Art eingesetzt, insbesondere dann, wenn es gilt, auf Paletten angeordnete Waren zu verpacken. Gearbeitet wird mit diesen Geräten dabei folgendermaßen:Such devices are already widely used in the packaging of goods of all kinds, especially when it is a matter of packing goods arranged on pallets. These devices work as follows:
Das Folienbahnende wird an der zu verpackenden Ware angelegt und dort zunächst festgehalten. Dann wird die Ware zunächst einmal und dann mehrfach rundum bewickelt, wobei die Folie so gedehnt wird, daß sie aufgrund ihrer Rückstellkraft an der Ware bzw. einer Folien-Unterschicht haften bleibt. Die Bewicklung kann dabei so vor sich gehen, daß die Ware vor dem Folienabroller gedreht oder dieser um die Ware herum geführt wird. In jedem Falle ist dabei dafür zu sorgen, daß sich die Folie nicht lose abwickelt, sondern unter Dehnung abgezogen wird, da sie sonst nicht an der Ware bzw. einer unteren Folien-Schicht haften bleibt. Hierzu ist eine mehr oder weniger starke Bremsung der Folienrolle erforderlich, die zudem dem Umstand Rechnung tragen muß, daß der Durchmesser der Folienrolle während des Wickelvorganges ständig abnimmt.The end of the film web is placed on the goods to be packaged and initially held there. Then the goods are first wrapped around once and then several times, whereby the film is stretched so that it sticks to the product or a film underlayer due to its restoring force. The wrapping can proceed in such a way that the goods are rotated in front of the film dispenser or this is guided around the goods. In any case, care must be taken to ensure that the film does not unwind loosely, but is pulled off under stretch, since otherwise it will not stick to the goods or a lower film layer. This requires a more or less strong braking of the film roll, which must also take into account the fact that the diameter of the film roll decreases continuously during the winding process.
Bei den bisher bekannten Folienabrollern der eingangs beschriebenen Art weist der Rahmen, in dem die Folienrolle gelagert ist, ein oberes, an einem Ende am ersten Rahmenlängsteil angelenktes Querteil auf, dessen anderes Ende mittels einer Stellschraube mehr oder weniger stark gegen das obere Ende des zweiten Rahmenlängsteiles gedrückt wird, mit der Folge, daß ein von dem Querteil getragenes und dort drehbar gelagertes Halteglied mehr oder weniger stark gegen die obere Stirnseite der Folienrolle gedrückt wird. Während des Wickel.vorganges ist die Betätigung der Stellschraube mühsam, oft sogar unmöglich, da.der Folienabroller in aller Regel mit beiden Händen gehalten werden muß und bei der Verpackung von höheren Gegenständen so stark angehoben werden muß, daß die Stellschraube überhaupt nicht erreicht-werden kann.In the previously known film dispensers of the type described at the outset, the frame in which the film roll is mounted has an upper cross part articulated at one end to the first longitudinal frame part, the other end of which, to a greater or lesser extent, against the upper end of the second longitudinal frame part by means of an adjusting screw is pressed, with the result that a holding member carried by the cross member and rotatably supported there is pressed more or less strongly against the upper end face of the film roll. During the winding process, the actuation of the set screw is laborious, often even impossible, since the film dispenser must generally be held with both hands and when packing higher objects it must be raised so much that the set screw cannot be reached at all can.
Der Erfindung liegt die Aufgabe zugrunde, hier Abhilfe,d.h. einen Folienhandäbroller zu schaffen, bei dem sich die Bremseinrichtung jederzeit, d.h. auch dann problemlos regulieren läßt, wenn es gilt, die oberen Bereiche höherer Gegenstände mit Dehnfolie zu umwickeln.The object of the invention is to remedy this, ie to provide a film hand roller in which the braking device can be moved at any time, ie even without problems can be regulated if it is necessary to wrap the upper areas of higher objects with stretch film.
Diese Aufgabe wird erfindungsgemäß durch einen Folienhandabroller gelöst, bei dem das Betätigungsglied für die Verstelleinirichtung von wenigstens einem drehbaren Rahmentangsteil gebildet ist, das im wesentlichen parallel zur Längsachse der Folienrolle verläuft. Bei einem so ausgebildeten Folienhandabroller kann die Verstelleinrichtung jederzeit problemlos von einer das Gerät haltenden Hand betätigt werden, unabhängig von der jeweiligen Arbeitshöhe.This object is achieved according to the invention by a film hand dispenser in which the actuating member for the adjustment device is formed by at least one rotatable frame part which runs essentially parallel to the longitudinal axis of the film roll. With a film hand dispenser designed in this way, the adjusting device can be operated at any time without any problem by a hand holding the device, regardless of the respective working height.
Die Verstelleinrichtung des erfindungsgemäßen Folienabrollers kann auf dessen Bremseinrichtung beispielsweise über einen Seilzug oder ein Zahnradgetriebe einwirken. Als besonders einfach in Herstellung und Handhabung hat sich jedoch eine Ausführüngsform erwiesen, bei der die Verstelleinrichtung längenveränderbar ist und die Rahmenquerteile durch Verkürzung der Verstelleinrichtung in an sich bekannter Weise in axialer Richtung auf den Kern der Folienrolle drückbar sind. Letzteres gilt insbesondere dann, wenn die beiden Rahmenquerteile und das sie verbindende weitere Rahmenlängsteil als Federbügel ausgebildet sind, der Rahmen also frei von Gelenk- und Steckverbindungen ist, was bei einer bevorzugten Ausführungsform des erfindungsgemäßen Folienhandabroller der Fall ist.The adjusting device of the film dispenser according to the invention can act on its braking device, for example via a cable or a gear transmission. However, an embodiment has proven to be particularly simple to manufacture and handle, in which the adjusting device can be changed in length and the frame cross parts can be pressed in an axial direction onto the core of the film roll in a manner known per se by shortening the adjusting device. The latter applies in particular when the two frame transverse parts and the further longitudinal frame part connecting them are designed as spring clips, that is to say the frame is free of articulated and plug-in connections, which is the case in a preferred embodiment of the film hand dispenser according to the invention.
Zur Längenveränderung des drehbaren Rahmenlängsteiles kann zwischen diesem und einem der Rahmenquerteile eine Stellschraube vorgesehen sein, die vorzugsweise gelenkig gelagert ist. Bei einer bevorzugten Ausführungsform sind zwei gelenkig gelagerte Stellschrauben vorgesehen, von denen eine rechts- und die andere linksgängig ist.To change the length of the rotatable longitudinal frame part, an adjusting screw can be provided between it and one of the frame transverse parts, which is preferably articulated. In a preferred embodiment, two articulated set screws are provided, by which one is right-handed and the other left-handed
Das drehbare Rahmen-teil kann als Drehgriff, vorzugsweise als Griffrolle oder Vierkantrohr ausgebildet sein und eine Länge aufweisen, die vorzugsweise im wesentlichen der Breite der Folienrolle entspricht.The rotatable frame part can be designed as a twist grip, preferably as a grip roller or square tube, and can have a length which preferably corresponds essentially to the width of the foil roller.
Das drehbare Rahmenlängsteil kann auch aus zwei teleskopartig zusammenwirkenden Teilen bestehen, die jeweils mit einem der Rahmenquerteile vorzugsweise über ein Gelenk drehbar verbunden sind. In jedem Falle hat es sich als vorteilhaft erwiesen, das drehbare Rahmenlängsteil zwischen den freien Enden der beiden Rahmenquerteile und die Lager für die Folienrolle im wesentlichen in der Mitte der Rahmenquerteile anzuordnen.The rotatable longitudinal frame part can also consist of two telescopically interacting parts, each of which is rotatably connected to one of the transverse frame parts, preferably via a joint. In any case, it has proven to be advantageous to arrange the rotatable longitudinal frame part between the free ends of the two transverse frame parts and the bearings for the film roll essentially in the middle of the transverse frame parts.
Die beiden Rahmenquerteile weisen vorzugsweise jeweils ein in der Arbeitsstellung stirnseitig in das Folienrollen-Innere ragendes Zentrierglied auf, wobei eines der beiden Zentrierglieder einen stirnseitig an der Folienrolle anliegenden B.und aufweist und drehbar gelagert ist, während dem anderen Zentrierglied eine stirnseitig auf die Folienrolle einwirkende Bremsscheibe zugeordnet ist, die auf einer Anschlagplatte drehbar gelagert ist.The two cross frame parts preferably each have a centering member protruding into the inside of the film roll inside in the working position, one of the two centering members having a face resting on the front of the film roll and being rotatably mounted, while the other centering member has a front acting on the film roll Brake disc is assigned, which is rotatably mounted on a stop plate.
Das Folienrollenlager ist vorzugsweise in an sich bekannter Weise als axiales Drucklager ausgebildet und weist dabei vorzugsweise ein Lagerteil auf, das relativ zum zugehörigen Rahmenquerteil in axialer Richtung verschiebbar und mittels einer Spanneinrichtung in axialer Richtung festlegbar ist. Dadurch kann die-Folienrolle in einfacher Weise in den Rahmen eingesetzt und eingespannt und nach Gebrauch wieder freigegeben werden, während die Verstelleinrichtung feinfühlig ausgebildet werden kann. Die Spanneinrichtung kann beispielsweise von einer Stellschraube gebildet sein. Als besonders praktisch, da einfach und problemlos zu betätigen, hat sich jedoch eine selbsthemmende Schnellspanneinrichtung erwiesen, die vorzugsweise nur zwei Endstellungen, nämlich eine Halte- und eine Freigabe-Stellung,besitzt. Diese Schnell spanneinrichtung kann ein als Kipphebel ausgebildetes Stellglied aufweisen, das an einer mit einem unter Federdruck stehenden Stellbolzen zusammenwirkenden Exzenterscheibe befestigt ist, wobei das der Exzenterscheibe abgewandte Stellbolzenende den drehbar gelagerten Folienrollenlagerteil trägt.The film roller bearing is preferably designed in a manner known per se as an axial thrust bearing and preferably has a bearing part which is displaceable in the axial direction relative to the associated frame cross part and can be fixed in the axial direction by means of a tensioning device. As a result, the film roll can be inserted and clamped in the frame in a simple manner and released again after use, while the adjustment device can be designed sensitively. The tensioning device can be, for example, from a Set screw must be formed. However, a self-locking quick release device has proven to be particularly practical, since it can be operated easily and without problems, and preferably has only two end positions, namely a holding position and a release position. This quick clamping device can have an actuator designed as a rocker arm which is attached to an eccentric disk cooperating with an adjusting bolt under spring pressure, the end of the eccentric disk bearing the rotatably mounted film roller bearing part.
An dem der Spannvorrichtung gegenüberliegenden Rahmenquerteil kann ein Stützfuß vorgesehen sein, der ein Abstellen des Gerätes am Boden ermöglicht. Der Stützfuß kann beispielsweise von einem Ring gebildet sein, dessen Durchmesser vorzugsweise größer ist als der Durchmesser einer vollen Folienrolle.A support foot can be provided on the frame cross part opposite the tensioning device, which enables the device to be parked on the floor. The support foot can be formed, for example, by a ring, the diameter of which is preferably larger than the diameter of a full film roll.
Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus den Ansprüchen und der folgenden Beschreibung einer bevorzugten Ausführungsform im Zusammenhang mit der Zeichnung. In der Zeichnung zeigen jeweils schematisch:
Figur 1 eine Seitenansicht eines erfindungsgemäßen Folienhandabrollers,Figur 2 eine Draufsicht auf den inFigur 1 dargestellte Folienhandabroller undFigur 3 Teile des inFigur 1 dargestellten Folienhändabrollers in vergrößertem Maßstab.
- FIG. 1 shows a side view of a film hand dispenser according to the invention,
- Figure 2 is a plan view of the film hand dispenser shown in Figure 1 and
- Figure 3 shows parts of the film hand roller shown in Figure 1 on an enlarged scale.
Der dargestellte Folienhandabroller weist einen von einem Metallring gebildeten Stützfuß 1 auf, der am unteren Querteil 2 des Geräterahmens befestigt ist. Das jeweils rechts dargestellte Ende des Querteiles 2 geht in ein rechtwinklig dazu verlaufendes Längsteil 3 des Geräterahmens über, an dessen anderem Ende sich das obere Querteil 4 des Geräterahmens rechtwinklig anschließt. Die beiden Querteile 2,4 und das sie verbindende Längsteil 3 des Geräterahmens sind einstückig ausgebildet und vorzugsweise aus einem Metallrohr mit flachem Rechteckquerschnitt gefertigt, so daß sie einen Federbügel darstellen, dessen von den Querteilen 2, 4 gebildete Schenkel mehr oder weniger stark auseinandergedrückt bzw. zusammengezogen werden können.The film hand dispenser shown has a
In der Mitte des unteren Rahmenquerteiles 2 ist eine kleine Lagerplatte 5 befestigt, auf der eine Bremsscheibe 6 drehbar gelagert ist. Oberhalb dieser Bremsscheibe 6 ist ein Zentrierglied 7 angeordnet, das in der Arbeitsstellung des Folienabrollers in das Innere der aufgeschobenen Folienrolle 8 ragt, während die Bremsscheibe 6 stirnseitig auf die Folienrolle 8 bzw. deren Kernrolle einwirkt.In the middle of the lower
Unterhalb der Mitte des oberen Rahmenquerteiles 4 ist ebenfalls ein Zentrierglied 9 vorgesehen. Dieses Zentrierglied 9 weist einen umlaufenden Bund 10 auf, der in der Arbeitsstellung stirnseitig gegen die Folienrolle 8 bzw. deren Kernrolle einwirkt. Das obere Zentrierglied 9 ist am unteren Ende eines Stellbolzens 11 drehbar gelagert, der in einer Ausnehmung des oberen Rahmenquerteiles 4 geführt ist. Das obere Ende des Stellbolzens 11 weist einen umlaufenden Bund auf, gegen den von unten eine Druckfeder wirkt, die sich nach unten gegen das obere Querteil 4 abstützt. Neben dem oberen Ende des Stellbolzens 11 sind am oberen Rahmenquerteil 4 zwei Laschen 12, 13 befestigt, zwischen denen eine Scheibe 14 gelagert ist. An der Scheibe 14 ist ein Kipphebel 15 befestigt. An der den Kipphebel 15 gegenüberliegenden Seite weist die Scheibe 14 einen halbkreisförmigen Bereich auf, an den sich einander parallele Scheibenseiten anschließen. Bei der dargestellten Stellung des Kipphebels 15 wird das obere Ende des Stellbolzens 11 von der auf ihn einwirkenden Druckfeder gegen eine dieser Scheibenseiten gedrückt. Die Scheibe 14 ist zwischen den beiden Laschen 12, 13 mittels eines Gelenkstiftes 16 exzentrisch gelagert, d.h. die Abstände der beiden einander parallelen Scheibenseiten zur Lagerachse sind unterschiedlich groß, mit der Folge, daß der durch Federdruck von unten gegen die Exzenterscheibe 14 gedrückte Stellbolzen 11 zusammen mit dem von ihm getragenen Zentrierglied 9 axial nach oben verlagert wird, wenn der Kipphebel 15 zusammen mit der mit ihm starr verbundenen Exzenterscheibe 14 aus der dargestellten Endstellung (Haltestellung) nach links in die zweite Endstellung (Freigabestellung) verschwenkt wird.A centering
An den freien Enden der beiden Rahmenquerteile 2, 4 sind miteinander fluchtende Durchbrechungen 17, 18 vorgesehen, in denen jeweils ein Ende einer Stellschraube 19, 20 mittels eines Gelenkstiftes 21, 22 gelenkig gelagert ist. Die eine dieser Stellschrauben 19, 20 weist ein Linksgewinde, die andere ein Rechtsgewinde auf. Beide Stellschrauben sind in Muttern eingeschraubt, die jeweils an einem Ende eines als Drehgriff 23 dienenden Rohres befestigt, vorzugsweise verschweißt, sind. Dieses Rohr bildet das zweite Rahmenlängsteil. Eine Betätigung des Drehgriffes 23 hat zur Folge, daß die beiden Stellschrauben 19, 20 mehr oder weniger weit in das Innere des Drehgriffes eingeschraubt werden und dies wiederum, daß die freien Enden der beiden Rahmenquerteile 2, 4 mehr oder weniger weit aufeinander zu- bzw. voneinander wegbewegt werden. Letzteres hat zur Folge, daß durch Betätigung des Drehgriffes 23 sich eine Feineinstellung des Abstandes der beiden Zentrierglieder 7, 9 durchführen läßt.At the free ends of the two
Mit dem dargestellten Folienhandabroller kann beispielsweise in folgender Weise gearbeitet werden:The film hand dispenser shown can be used, for example, in the following way:
Zunächst wird der Kipphebel 15 aus der dargestellten Endstellung nach links geklappt, so daß der Stellbolzen 11 und damit das obere Zentrierglied 9 durch die auf den Stellbolzen 11 einwirkende Feder nach oben verlagert wird. Ist dies geschehen, kann auf das untere Zentrierglied 7 eine volle Folienrolle 8 aufgesetzt werden. Nach Ausrichten der Folienrolle ist der Kipphebel 15 wieder nach rechts in die dargestellte Endstellung zu verschwenken, wobei das obere Zentrierglied 9 in das Innere der Folienrolle bzw. deren Kernrolle eingreift. Die Folienrolle 8 wird jetzt von den beiden Zentriergliedern 7, 9 gehalten und kann mehr oder weniger leicht gedreht werden, wobei die Wirkung der einerseits mit der Folienrolle 8 und andererseits mit der Lagerplatte 5 zusammenwirkenden Bremsscheibe 6 von der Beschaffenheit der Bremsscheibe und von dem von der Folienrolle 8 ausgeübten Auflagedruck abhängt. Die Bremswirkung der Bremsscheibe 6 kann jedoch durch Betätigung des gleichzeitig als Haltegriff dienenden Drehgriffes 23 verändert werden. Dabei spielt die Höhe, in der mit dem Folienabroller jeweils gearbeitet wird, keine Rolle, da die Verstelleinrichtung ihrer Bremseinrichtung auch in den extremsten Lagen leicht zugänglich ist.First, the
