Description

The invention relates to a cutting tool for cutting a free before a workpiece plate portion of a band edge, which is fixed to a front side of the workpiece plate, wherein the cutting tool a side-stop surface for supporting on an adjacent to the front side extending side, in particular a top, the workpiece plate wherein the cutting tool has a first cutting tool arranged on a base body and a second cutting tool movably mounted to the first cutting tool which can be brought into cutting engagement with one another for cutting the band, the cutting tool having at least one end stop member for supporting the cutting tool at the front the workpiece plate at a distance from the cutting tools, and wherein the cutting tool for cutting the band edge at an edge between the Umleimerband bearing Stirnsei te and a free end face of the workpiece plate has an edge side stop bracket.

A cutting tool of this kind is for example off EP 1 854 602 B1 known. With the known cutting tool can be such as in FIG. 1 the font shown in front of a narrow side edge projecting portion of a band band be cut off, so to speak be cut. By accordingly careful handling or clever insertion of the known cutting tool, it is possibly also conceivable with this cutting tool a band edge so to speak to cut so that the band edge with its flat cut, frontal edge next to a frontally cut and already located on the workpiece plate banding can be attached abutting the front side. However, this is extremely difficult to handle.

It is therefore the object of the present invention to provide a cutting tool that can be used universally.

To achieve the object is provided with a cutting tool of the type mentioned, it has for cutting the band for later attachment to a still free end side portion of the same end face, in front of the band, a shock side stop bracket, and that the Stirnseitenanschlagkörper either at the joint Side stop bracket or the edge side stop bracket is mounted and / or that the end stopper body on the side stop bracket to which it is located between a before the minor side abutment surface to the front side of the workpiece plate projecting working or use position and one not in front of the minor side abutment surface the workpiece plate protruding rest position or non-use position is adjustable.

With the solution according to the invention, it is possible to use the cutting tool readily not only for cutting or cutting of banding strips on a workpiece plate edge, but also for producing a frontal Kapp-section of an intended for mounting on impact with a neighboring band band Umleimerbands.

The inventive concept not only provides that a shock side stop bracket is provided, but that you can make do with a single Stirnseitenanschlagkörper preferably, which can be selectively mounted on one or the other side stop bracket. Another advantageous approach provides that the end face stop body is adjustable between a working position and a rest position provided in front of the auxiliary side abutment surface to the workpiece plate, for example displaceable, pivotable or both, in which the side abutment body so to speak no longer bothers, that is no longer or not in the sense of a stop projecting in front of the side-stop surface and thus the cutting tool is used, for example, for producing a butt-section, when the respective Stirnseitenanschlagkörper is arranged on the edge side stop bracket, or for producing a Edge cut of Umleimerbands is usable when the Stirnseitenanschlagkörper is disposed on the shock side stop bracket. The adjusted in the rest position Stirnseitenanschlagkörper thus does not interfere with a free positioning of the cutting tool on the workpiece plate for producing a shock-cut or edge-section of Umleimerbands.

It should be noted that, of course, in the cutting tool according to the invention more Stirnseitenanschlagkörper can be provided, for example on each side stop bracket at least one end stop body, which is then conveniently adjustable between the rest position and the working position.

For example, it is possible to slidably receive the end stop body in a slide bearing or slide receptacle that forms part of the respective side stop bracket (shock or edge side stop bracket). A pivoting of the end stop body in the working position or the rest position or a combined operation (push and pivot) is readily possible.

A self-contained invention represents a following defined cutting tool:

• A cutting tool for cutting a portion of a banding band freely protruding in front of a work plate fixed to a front side of the work sheet, the cutting tool having a minor side abutment surface for supporting on a side adjacent to the end side, particularly a top side, of the workpiece plate The cutting tool has a arranged on a base body first cutting tool and a second, to the first cutting tool movably mounted cutting tool, which can be brought into a cutting engagement with each other for cutting the band edge, wherein the cutting tool at least one Stirnseitenanschlagkörper for supporting the end face of the cutting tool on the workpiece plate in a Distance to the cutting tools, and wherein the cutting tool
  • for cutting the edge band at an edge between the end face carrying the banding strip and a free end side of the workpiece plate, an edge side stop holder and / or
  • for cutting the edge band for later attachment to a still free end side portion of the same end face, in front of which protrudes the Umleimerband having a shock side stop bracket. The cutting tool is characterized in that the impact side stop bracket and / or the edge side stop bracket has a motion bearing or a transmission for sliding movable and / or pivotable mounting of Stirnseitenanschlagkörpers. It is thus possible for the cutting tool to have either an edge side stop bracket or a collision side stop bracket, or both in which a particular fine adjustment of the side impact relative to the base body of the cutting tool, such as relative to the first cutting tool or its base, by a bearing or gear or both Cutting edge is possible.

Of course, the measures mentioned below or also the measures already explained above can be realized in the cutting tool explained in the paragraph above. Preferably, also in this cutting tool, it is provided that the end stop member is selectively mountable to the push side stop bracket or the edge side stop bracket, and / or that the end stop member is attached to the side stop bracket to which it is disposed between one in front of the minor side abutment surface and the front end the workpiece plate projecting working position and a non-front of the minor side abutment surface to the workpiece plate protruding rest position is adjustable.

In any case, a preferred embodiment of the invention provides that the impact side stop holder and / or the edge side stop holder has a motion bearing or a gearbox for the slide-movable and / or pivotable mounting of the front end stop body. This has already been indicated above.

An expediently measure forms it, when the end stop body is movably mounted on the shock side stop bracket or the edge side stop bracket based on a Exzenterlagers or Exzentergetriebes and / or a suitable for fine adjustment reduction gear. By means of such a transmission, for example, a fine relative adjustment of the side stop body to, for example, the first cutting body is possible. Of course, you could also provide a screw gear or the like other expediently a reduction gear realizing.

It is based on the consideration and knowledge that only a very small adjustment of the side stop body are to be set to a precise cutting of the band band in the correct length usually, which is easily possible on the basis of a fine gear.

In connection with the eccentric or eccentric bearing, it is advantageous if, for example, an eccentric wheel is rotatably mounted on a Nebenseitenanschlagkörper the Ablängwerkzeugs and holds the side stop body or forms.

The intended for use of an eccentric or eccentric bearing side stop body expediently has a circular outer circumference. In this respect, in each rotational position or angular position of the front end stop body, when it is adjusted by the eccentric or eccentric, a same Stirnseitenanschlagflächenkontur ready.

An advantageous measure provides for a holding device, for example a screw, a lever or the like, which is provided for fixing the end stop member to the eccentric wheel or another setting wheel of the transmission, also in the course of fastening the front end stop member Eccentric wheel or thumbwheel on the basic structure of the cutting tool, for example, a Nebenseitenanschlagkörper, determines, for example, clamped.

It is advantageously provided that the front end stop body on the motion bearing or the gearbox for selective use on one of the two side stop brackets, the shock side stop bracket or the edge side stop bracket, is detachably fastened. Thus, you can therefore use the front end stop body, which is, for example, pin-shaped, optionally on the respective side stop bracket.

An advantageous measure provides that the eccentric bearing or eccentric a guide slot, for example, an arcuate guide slot, opposite, in which engages the side stop body. Of course, it would also be possible that the side stop body is guided by means of two opposing eccentric or eccentric.

Appropriately, it is provided that a longitudinal direction of the cutting tools, in which they perform the cut on Umleimerbands, and the Nebenseitenanschlagkörper are approximately at right angles to each other. However, if the minor side and the front side of the work sheet enclose an angle, it is also conceivable that the auxiliary side stopper body and a longitudinal extension direction of the cutting tools are not at right angles to each other but at an acute or obtuse angle.

It is also possible to apply the cutting tool with the side stop surface at the top or the bottom of the workpiece plate. In other words, you could do one Also, in this position, the auxiliary side stopper body having the auxiliary side stopper surface may be referred to as an upper side or lower side stopper body. The terms "top" and "bottom" are therefore not necessarily to be understood as horizontal top or bottom, but also include situations in which, for example, the cutting tool is inserted horizontally from the side to the workpiece plate, so that the side side, for example, a vertically extending Side of the workpiece plate is.

The end stop member or end stop members are conveniently mountable on at least one of the side stop supports, such as the edge side stop bracket or the butt side stop bracket, at least two spaced apart from the first cutting tool. In this way, a fine adjustment of the distance between the cutting tools and the workpiece plate for adjusting the length, which is cut off from the banding band, possible. For example, so the impact end face can be cut exactly in the adjustable length so that the shock-end side of the remaining rest of the band edge flush with a shock-end side of a band edge, which is already mounted on the front side of the holding plate connects.

Thus, the end stopper body in several positions relative to the first cutting tool, so the fixed cutting tool, can be mounted, for example, a plurality of juxtaposed receptacles or brackets may be provided for example designed as a pen or a pin end face stopper body. Preferably, however, is a Montagekulisse, for example, a linear backdrop or an arcuate backdrop on which the side stop body in the at least two distances mountable is. It is example side possible to loosen a clamp-holder of Stirnseitenanschlagkörpers to move it along the Montagekulisse and then set in another position again, for example, to jam.

The at least one end stop body comprises e.g. a pin or a rod or a tubular body, in particular with a round, preferably circular, circumference.

It is preferred if the cutting tool has a front side stop face, which is provided in particular on the base body and is located in front of the first cutting tool, for engagement with the end face of the work piece plate. The end stopper body is attachable to the butt side stopper bracket at least two distances relative to the end stopper surface. The front-side abutment surface is expediently so narrow or punctiform or linear, that the cutting tool is pivotable about this end-side abutment surface. The front-side abutment surface defines, as it were, a pivot axis about which the cutting tool pivots on the end face of the workpiece plate. The Stirnseitenanschlagkörper then forms a pivot stop. The pivoting angle of the cutting tool or the angle at which the cutting tools are relative to the face of the workpiece plate depends on the position of the face stopper body on the butt side fence mount. As a result, the length of the section of the band, which is cut off, exactly adjustable. Thus, the length of the portion of the band of bandage to be cut can be optimally adjusted.

It is advantageously provided that the cutting tool has a second auxiliary side abutment surface, which is opposite to the auxiliary side abutment surface, for supporting on an end side extending opposite to the first side Side, in particular a bottom, the workpiece plate or for supporting on or on the side, in particular the top, the workpiece plate in a rotated by 180 ° position of the cutting tool. This constitutes an inherent inventive concept, ie it may, but does not have to include one or both of the side stop supports mentioned in claim 1.

Thus, the cutting tool can be used, for example, by simply turning over to cut off from each other opposite edges of the workpiece plate projecting portions of the band.

The cutting tool expediently has at least one auxiliary side stop body, on which one or both side stop holders are provided.

The first and second minor side abutment surfaces are suitably provided on opposing auxiliary side abutment bodies, at least one of the auxiliary lateral abutment bodies having the or one impact side stop holder and / or the one or edge side stop holder.

The Nebenseitenanschlagkörper expediently have opposing Seitenanschlaghalterungen. For example, the bump side stop bracket of one side bumper faces a bump side stop bracket of the other side bumper. The same applies to the edge side stop brackets, which are expediently provided opposite one another on the two opposite side stop members.

It is preferred if the auxiliary side stop body can be connected to one another by the front end stop body or bodies.

The one or more Nebenseitenanschlagkörper expediently in the manner of side legs of the base body at an angle, for example at right angles, from.

It is e.g. conceivable that only a single Nebenseitenanschlagkörper is provided so that it forms, for example, with the base body an L-shaped configuration. If two opposing Nebenseitenanschlagkörper are provided, these form for example a U-shaped receptacle for the workpiece plate.

It should be noted here that it is a separate invention to provide on a base body two opposing Nebenseitenanschlagkörper so that the cutting tool in 180 rotated positions once with the one Nebenseitenanschlagkörper or its Nebenseitenanschlagfläche and the other time with the other Nebenseiten Stop surface on the same side, for example, the top, the workpiece plate can be applied. It is then convenient, but not essential, for the one or both of the side panel abutments to have an edge side stop bracket or a butt side stop bracket or both.

The base body and / or at least one auxiliary side stop body are expediently plate-shaped.

At least one Nebenseitenanschlagkörper expediently has a support plate.

The Nebenseitenanschlagkörper, in particular the support plate is expediently ribbed or has ribs so that it is light. It is also possible for the base body to have a ribbing that reinforces it.

The base body is made of metal, for example, while the side impactor body or bodies are made of plastic. For example, you can screw the components together, gluing, jamming or the like

But it is also possible that the base body and at least one Nebenseitenanschlagkörper are integral.

To the cutting tools is still the following. The first cutting tool and the second cutting tool expediently have a frontally prismatic and a frontally right-angled cutting blade. However, it is possible for the example side to have the first cutting tool a right-angled, the second cutting tool a prismatic end face or cutting blade. Furthermore, it is possible for the first cutting tool and / or the second cutting tool to be detachably fastened to the base body and to a tool carrier holding the second cutting tool and movably mounted on the base body. For example, it is possible to use different cutting tools for different types of cuts. Furthermore, it is possible to exchange tool bodies used as first and second cutting tools, so that for example the cutting tool having the prismatic blade is fixed to the base body while the cutting tool equipped with the right-angled blade is movable relative to the first cutting tool or vice versa that the cutting tool with the right-angled blade fixed to the base body while the other cutting tool is moved with the prismatic blade toward and away from it.

A tool carrier supporting the second cutting tool and movably supported relative to the base body is, for example, a carriage.

For example, the base body has a window through which to cut off the portion of the banding tape. The second actuating body closes the window, so to speak, and cuts off the banding strip.

The cutting tools, for example, in the manner of a guillotine or a pair of shears to each other to move to shear off the banding strip quasi.

An end face abutment surface of the face abutment body expediently aligns with a bottom surface of the first cutting tool or the second cutting tool in a plane when the end stopper body is attached to the edge side stop bracket and protrudes in front of the minor side abutment surface particularly in the operative position.

On the other hand, the end-face abutment surface of the end-face abutment body or other end-face abutment body, when secured to the impact side stop bracket in the operative position, is spaced from a shear plane in which the cutting tools are moved relative to one another.

A cutting tool 10 has abutment members 11 and 12 provided for abutment with a work plate 80 or 90, which have a minor side abutment surface 13 and 14, with which the cutting tool 10, for example, on a side forming a minor side 81 of the workpiece plate 80 or also a side forming bottom 82 of the workpiece plate 80 and, mutatis mutandis, in the workpiece plate on the top 91 or the bottom 92 is applied. It is also possible to rotate the cutting tool 10 through 180 °, so that the auxiliary side abutment surface 14 comes to lie on the upper side 81 or 91, see, for example FIGS. 2 and 3 ,

The two Nebenseitenanschlagkörper 11 and 12 project in front of a base body 15 in the manner of side legs.

The base body 15 comprises, for example, a base plate 16 from which side wall sections 17, such as side legs, are angularly secured, e.g. right angle, stand out. The wall sections 17 and the base plate 16 form, for example, a U-shaped configuration.

The wall sections 17 serve, inter alia, as a carrier for the auxiliary side stop members 11 and 12. The auxiliary side stop members 11 and 12 each have, for example, a receptacle 18 into which the base body 15, in particular the wall sections 17 engage. For example, the auxiliary side stop members 11 and 12 are screwed in the region of the receptacles 18 with screws 19 with the wall sections 17.

On the base body 15, a window 20 is provided through which a respectively abzulängender section 75 or 76 of the the workpiece plate 80 fixed Umleimerbands 70 or a portion 77 of the attached to the workpiece plate 90 Umleimerbands 70 can pass to be cut off using cutting tools 21 and 22.

The cutting tools 21 and 22 comprise cutting blades, which are fastened on the base body 15, on the one hand, by means of screws 23 or other fastening elements enabling releasable fastening, on the one hand, and on a tool carrier 24 movably mounted on the base body 15 in the manner of a slide, on the other hand.

When the two cutting tools 21 and 22 are moved toward each other, the two cutting edges 25 and 26 shear off the banding band 70 passing through the window 20.

The one cutting tool 21 and the other cutting tool 22 can optionally be attached to the base body 15 or to the tool carrier 24, so that, for example, an in FIG. 5 visible right-angled cutting edge 25 of the cutting tool 21 once on the base body 15, as shown, and the other time on the tool carrier 24 on which in the illustrated variant, the other cutting tool 22 is mounted, which has a prismatic or inclined cutting edge 26.

The cutting tool 10 can be grasped on a handle 27 projecting upwards in front of the base body 15. The handle 27 is, for example, like a gag and extends transversely to a support arm 28 which is secured to the base body 15, for example by means of a screwed to the base plate 16 are support base 29 from which the support arm 28 protrudes.

The handle 27 and the two Nebenseitenanschlagkörper 11 and 12 are on opposite sides of the base body 15 from.

On the base body 15, an actuating lever 30 is pivotally mounted. For example, a bearing shaft 31 penetrates the two wall sections 17 in the region of the handle 27 and the support base 29. The bearing shaft 31 extends, for example, between the two wall sections 17 and is mounted so as to be non-displaceable with respect to its longitudinal extension direction by means of, for example, split rings 55 or the like of other fastening elements , For example, For example, the bearing shaft 31 may rotate within bearing bores on the wall sections 17 through which it passes. It is also possible that, for example, the actuating lever 30 can rotate relative to the bearing shaft 31.

The actuating lever 30 includes, for example, a handle 32 at its free from the base body 15 longitudinal end. The handle 32 is arranged, for example, on lever arms 33, which carry the handle 32 at one longitudinal end, and are mounted pivotably on the base body 15 in the region of their other longitudinal ends 34. For example, the bearing shaft 31 penetrates the lever arms 33 in the region of the longitudinal ends 34.

The longitudinal ends 34 of the lever arms 33 are engaged with the tool carrier 24. The tool carrier 24 comprises, for example, arms 35 which project toward the lever arms 33 and into which the lever arms 33 engage in the region of the longitudinal ends 34. The longitudinal ends 34 themselves, for example, penetrate the arms 35 of the tool carrier 24 in a pivotable manner and engage in recesses 36 on the base plate 16 of the base body 15. The recesses 36 are configured in the manner of short longitudinal slots, which preferably lead the lever arms 33 and / or expediently limit their pivotal movement about the defined by the bearing shaft 31 pivot axis or axis of rotation of the actuating lever 30.

The tool carrier 24 is movably mounted on the base body 15 in a longitudinal direction 37.

The arms 35 extend laterally past the support base 29. Conveniently, the arms 35 of the tool carrier 24 between the top of the base plate 16 and a bottom of the plate-like support base 29 are guided. For example, the arms 35 are arranged between the support base 29 and the wall portions 17 and can be moved there in the longitudinal direction 37 back and forth.

The arms 35 are connected to a cutting tool 22 supporting support portion 38 of the tool carrier 24 and stand from this laterally in the manner of side legs to the actuating lever 30 from. It is also possible that the cutting tool 22 is directly connected to the arms 35, for example screwed to this.

Now, when the handle 32 is moved toward the handle 27, the second cutting tool 22 is moved toward the first cutting tool 21 and brought into cutting engagement to cut off the banding tape 70. In this case, the cutting edge 26 moves along the longitudinal direction 37 to the cutting edge 25, that is, the window 20 is smaller, so to speak.

A spring assembly 39 loads the tool carrier 24 in an open position in which the cutting tools 21 and 22 are moved away from each other. The spring arrangement 39 includes, for example, a leg spring 40, which is supported on the one hand on the base body 15 and on the other hand on the actuating lever 30. The spring arrangement 39 loads the operating lever 30, for example, in a pivoting position of the handle 27 away.

The auxiliary side abutment bodies 11 comprise, for example, support plates 41 which protrude laterally in front of the base plate 16 and consequently the base body 15.

The Nebenseitenanschlagkörper 11 for example, have a ribbing 42, so are particularly lightweight. It is preferable if the auxiliary side stopper bodies 11 and 12 are made of plastic, so that they are particularly lightweight. But a metal casting is readily possible to produce, for example, the ribbing 42.

The production of plastic or other material also allows the production of the receptacles 18 in a particularly favorable manner. Of course, it would also be possible to produce the base body 15 and the two auxiliary side stop members 11 and 12 in one piece, for example of plastic. However, the multi-part construction makes it possible to adapt the cutting tool 10 very easily and with little effort to the respective work situation.

An underside 43 of the cutting tool 22 which can be brought into overlap with the upper side of the cutting tool 21 in order to carry out the cutting engagement is arranged in a contact plane 44. In this plant level 44 and a front-side abutment surface 45 of a Stirnseitenanschlagkörpers 46 is arranged when this as in the Figures 2-7 shown mounted on edge side stop brackets 47 of the cutting tool 10.

The end stopper body 46 includes, for example, a pipe body or bar body. Longitudinal ends 48 of Stirnseitenanschlagkörpers 46 are received in the example, receiving wells or recesses 49 having edge side stop brackets 47.

The edge side stop supports 47 are provided opposite to the side stop members 11 and 12 in the area of the minor side abutment surfaces 13 and 14, and are located at a longitudinal distance 50 to the cutting edge 25 of the cutting tool 21. Thus, the cutting tool 10 can be removed from the cutting tools 21 and 22 to the plant with a front end face 83 or a rear end face 84 of the workpiece plate 80 are brought when the attached to the longitudinal end face 85 Umleimerband 70 at the front portion 75 or rear portion 76, at least in front of an edge 86 or 87 of the workpiece plate 80th projecting Längsendbereich to be cut off.

The longitudinal end face 85 and the front end face 83 and the rear end face 84 are at an angle to each other, e.g. in the present case rectangular, although other angles are conceivable. The longitudinal end face 85 and the end faces 83, 84 abut against one another at the edges 86 and 87.

The upper side of the cutting tool 21 and the underside of the other cutting tool 22 are aligned in principle with the front or rear end face 83 or 84, so that the banding band 70 is cut flush with this end face 83 or 84.

The cutting tool 10 rests firmly and flat against the work plate 80, wherein the end faces of the ribs of the ribbing 42, the side-stop surfaces 13 and 14 and form a large-scale contact with the side surfaces, namely the top 81 or the bottom 82, the workpiece plate 80th enable.

The operator may also grasp and hold the cutting tool 10 on recessed grips 65 provided on the outer side abutment surfaces 11 and 12 opposite the minor side abutment surfaces 13, 14. Of course, there could also be provided handles or the like other conveniently grippable operating handle.

The cutting edge 25 of the cutting tool 21 bears against a front side 71 of the banding tape 70, while the other cutting tool 22 makes the cut from the rear side 72 of the banding band 70.

With its rear side 72, the banding band 70 is attached to the longitudinal end face 85 of the work piece plate 80, e.g. glued.

The front end stop body 46 is inserted into the recesses 49, that is, it lies with its outer periphery on the inner circumference of the recesses 49, which for example have a cylindrical inner circumference.

By means of the bottom of the respective recess 49 from the outside of Nebenseitenanschlagkörpers 11, 12 ago penetrating screw 51, the end stop member 46 can be additionally determined. It is understood that it would also be sufficient to hold the end stopper body 46, for example in a press fit, by means of a latch or the like of other releasable connection in the two edge side stop supports 47 in a sufficiently fixed position for cutting the banding band 70.

It is also possible that, for example, one or both of the side stop holders 47 comprise an insertion opening, For example, a sliding bearing 56, so that the end stopper body 46 in an in FIG. 3 dashed shown non-use position or rest position R is displaced while in FIG. 2 is displaced into its position of use or working position A, in which it protrudes downward in front of the auxiliary side abutment surface 13 and is ready to abut against the end face 83 or 84.

However, one can also remove the end face abutment body 46 from the edge side stop mounts 47 so that, as shown in FIGS FIGS. 8 and 9 becomes clear, the banding 70 can also cut to length shock. For this purpose, the edge side stop holders 47 expediently have suitable insertion openings 67, for example insertion grooves or the like, for lateral insertion of the front side abutment body 46.

The banding band 70 is fastened with its rear side 72 or adhesive side to a circumferential longitudinal end face 95 of the workpiece plate 90. A longitudinal end 78 of the banding band 70 is already completely attached to the longitudinal end face 95, while from the other longitudinal end of a portion 77 protrudes freely in front of the longitudinal end face 95 and is to be cut.

In this situation, the end stop body 46 is removed from the edge side stop supports 47 and secured to push side stop supports 52.

The impact side stop supports 52 are spaced at a transverse distance 53 from the cutting tools 21 and 22. Thus, therefore, the impact side stop brackets 52 and attached end face abutment body 46 are not in the cutting plane of the two cutting tools 21 and 22, but at a transverse distance 53 thereto.

Between the edge side stop holders 47 and the cutting tools 21 and 22 is still an end-side abutment surface 54, for example, on the narrow end face of the base plate 16. With the front side abutment surface 54, the cutting tool 10 can at a free end portion 96, which is located between the end face 79 of the longitudinal end 78 of the already attached to the workpiece plate 90 banding band 70 and the other longitudinal end, which is to be cut, is supported.

Further support is provided by end face abutment 46 which is secured in thrust side stop bracket 52.

The cutting tool 10 can pivot about a pivot axis 64 running along the end stop surface 54 or defined by it. The respective angular position of the cutting tool 10 with respect to the pivot axis 64 and thus the position of the cutting tools 21, 22 to be cut down portion 77 of the Umleimerbands 70 is defined by the voltage applied to the free end portion 96 end face abutment body 46. This angular position requires the length of section 77 which is cut off.

The shock side stop supports 52 include mounting lobes 57 in which the end stop body 46 is longitudinally displaceably received along an axial direction 58. A scale 59, which is arranged next to the mounting lugs 57, makes it possible to read the respective longitudinal position of the front side stop body 46 in the impact side stop holders 52. Preferably, it is provided that the scale 59 correlates with a length of the portion 77 or corresponds to this length, which must have this, so that its free end face 100 in abutment with the end face 79th at the longitudinal end 78 of the already glued to the longitudinal end face 95 portion of the Umleimerbands 70 is exactly assembled.

The mounting slots 57 include, for example, longitudinal grooves 60 for receiving a respective longitudinal end 48 of the end stop 46. The longitudinal grooves 60 are preferably provided at one longitudinal end with apertures 61 so that the end stop 46 can be inserted through the apertures 61 into the respective longitudinal groove 60.

The mounting link 57 or the longitudinal grooves 60 also make it possible to displace the front end stop body 46 even far away from the second cutting tool 22 in the direction of the first cutting tool 21 in such a way that, as in FIG FIG. 3 represented a rest position R occupies, so the investment of Ablängwerkzeugs 10 for an edge section of the Umleimerbands 70, such as in FIGS. 2 and 3 shown, not handicapped. The Montagekulisse 57 and the longitudinal grooves 60 thus also form a sliding bearing.

Conveniently, a washer 63 is provided below the screw 51 and its head. The screw 51 penetrates the example configured as a slot mounting backdrop 57th

The end stopper body 46 attached to the opposing butt side stopper brackets 52 or edge side stopper brackets 47 forms a connecting web between the auxiliary side stopper members 11 and 12, which acts to reinforce and stabilize the cutting tool 10.

Also in the recesses 49 and edge side stop brackets 47 expediently openings 62 are provided to the end face abutment 46 from the edge side stop brackets 47, that is the gap between those Nebenseitenanschlagkörpern 11 and 12 refer.

In the present case, an upper end face 73 and a lower end face 74 of the banding band 70 are not in front of the secondary sides of the workpiece plates 80 or 90, that is, in front of the upper side 81, 91 or the lower side 82, 92 thereof.

However, the distance between the minor side abutment surfaces 13 and 14 is sufficiently large, that is convenient to turn the Ablängwerkzeug 10 and in the two in the FIGS. 2 and 3 to apply shown positions, even if the upper side 73 or the lower end face 74 of the band Umleimerbands 70 vorstünden before the side surfaces of the workpiece plates 80 or 90 at the respectively used auxiliary side abutment surface 13 or 14.

Preferably, in the region of the window 20, where the portions 75, 76, 77 of the banding band 70 to be cut pass through the window 20 and reach the area of the auxiliary side abutment surfaces 13 and 14, in each case a recess 66 on the auxiliary side abutment surfaces 13 and 14, so that an optionally with its upper or lower end face 73, 74 projecting banding strip 70 can still be introduced into the space between the Nebenseitenanschlagkörpern 11 and 12.

It should also be mentioned that, for example, the wall sections 17 could be so dimensioned and instead of protruding to the top to the bottom of the base plate 16 so that they could integrally form the auxiliary side stop body 11 or 12.

In the in the FIGS. 10 and 11 Modified cutting tool 110 illustrated are partially the same or similar components provided as in the cutting tool 10. Insofar, the same reference numerals are used and the components are not explained in detail. For example, the cutting tool 110 has, in principle, the auxiliary side abutment bodies 111, 112 corresponding to the auxiliary side abutment bodies 11, 12, which are arranged on the base body 15. The two cutting tools 21 and 22 are present.

It has been found that it is advantageous when just when cutting the band edge on impact, as in the FIGS. 8 and 9 shown, should be able to realize a very fine adjustment of the position of the end stopper body relative to the respective fixed cutting body. Surprisingly, namely even with rounding of the workpiece plate with a large radius of Stirnseitenanschlagkörper must be adjusted only by a relatively small amount in order to determine the correct length of the cut off portion of the Umleimerbands.

For example, a fine adjustment of the end stop member 146 allows an eccentric gear 170 in the cutting tool 110.

The end stop member 146 is suitable for use on the one hand on an edge side stop bracket 147, which includes 47b, 47a provided on the Nebenseitenanschlagkörpern 111, 112 shots. For example, the end stopper body 146 is insertable via lateral insertion openings 167, 168 in the receptacles 47a and 47b from a peripheral side of the two Nebenseitenanschlagkörper 111, 112 forth, wherein a longitudinal end 145 of the Stirnseitenanschlagkörpers 146 engages the receptacle 47a and an opposite longitudinal end 148 in the other receptacle 47b intervenes. At the longitudinal end 148, for example, a plug-in projection 149 is provided, which can engage in the receptacle 47b against rotation.

To further fix the end stop member 146 is a screw 151, the screw portion 152 is durchsteckbar through an insertion opening 154 on Nebenseitenanschlagkörper 111 and then from above into a screw 150 at the longitudinal end 148 of Stirnseitenanschlagkörpers 146 can be screwed. The screw 151 is very easy to handle by a handle 153. Of course, could be provided instead of a screw, for example, a toggle clamp or the like. When the screw 151 is removed, the end stopper body 146 may be removed from the edge side stop bracket 147.

The eccentric gear 170 comprises an eccentric wheel 180, which is rotatably received in a pivot bearing 173 of the Nebenseitenanschlagkörpers 111. The eccentric 180 is in two parts and comprises a wheel body 174 which is inserted from the auxiliary side abutment surface 13 ago in the receptacle 173 and is held there by a cover 171. The wheel body 174 and the cover 171 project radially outward in front of the receptacle 173, so that the eccentric wheel 180 is accommodated rotatably but immovably in the receptacle 173 with respect to a rotation axis 181.

In front of the cover 171 are 174 locking hooks 175 to the wheel body, which are hooked into locking receptacles 176 of the wheel body 174. Of course, another connection would be readily possible. An additional rotationally fixed support of the lid 171 on the wheel body 174 is ensured by a holding web or a holding receptacle or other form-fitting contour 177 of the lid 171, which is in engagement with a counter-form-fitting contour 178 on the wheel body 174.

On the eccentric 180, a receptacle 183 for the positive retention of the male projection 149 of the end stop member 146 is provided. The plug-in projection 149 has lateral flattening, that is to say a peripheral contour provided for a non-rotatable hold in the receptacle 183, which has a matching inner peripheral contour which is not visible in the drawing. Thus, therefore, the plug-in projection 143 is rotatably held in the receptacle 183.

This non-rotatable hold can also be made without form fit, because in a particularly advantageous manner, the screw 151 is inserted through an insertion opening 172 on the eccentric 180 and screwed into the screw 150 of the front end stop body 146.

The receptacle 183 is eccentric to the axis of rotation 181, so that upon rotation of the eccentric wheel 180, the end stop member 146 undergoes an eccentric rotation about the axis of rotation 181. The end stopper body 146 has e.g. a pin-shaped or bolt-like shape.

Since an outer periphery 144 of the end stopper body 146 is circular, a suitable end face abutment surface 45 of the end stopper body 146 always abuts on the work plate 90 regardless of the rotational position of the eccentric wheel 180 and thus the end stopper body 146.

At the side stopper body 112, the end stopper body 146 is guided by a guide receptacle 182. In the present case, this has a substantially round, but flattened on one side inner contour, so that the end stop member 146 can pass through the entire curved path about the axis of rotation 181. Since the front side abutment body 146 via the rotation axis 181 protrudes, no curved guide receptacle 182 is possible in the present case. But that would be conceivable without any problems if the geometrical relationships were different.

It would also be possible for the front end abutment body 146 to be braced in the region of the guide receptacle 182 by means of a screw, an eccentric lever, a knee lever or the like.

An outer circumference 179, which is expediently provided with a corrugation, can be grasped by a user in a recess 184 of the auxiliary side stop body 111, so that the following, very simple operation is possible: the end-side abutment surface 54 is in contact with the already glued banding band 70, namely whose front side 79 created. The operator then turns the eccentric wheel 180 until the end stopper body 146 abuts against the workpiece plate 90 at the end portion 96, the cutting tool 10 pivots about the end face abutment surface 54. Then the dimension for the section of the banding strip 70 to be cut-off, that is to say for cutting off the section 77 of the correct length, is correct. In this case, the operator does not even need to read the expediently provided scale 159, which is provided on the outer circumference of the receptacle 173, and to make the adjustment on the basis of this scale 159.

In a final step, for example, the operator then pulls on the screw 151, at the same time clamping the eccentric wheel 180 with the auxiliary side stop 111 and thus fixing the position of the end stop 146 relative to the basic structure of the cutting tool 110, namely the auxiliary side stop 111. Namely, the screw 151 clamps a first part of the eccentric wheel 180, the lid 171, against the one side (outer side) of the auxiliary side stopper body 111, while at the same time forming a second part of the Eccentric wheel 180, the wheel body 174, attracts against the other side or opposite side of Nebenseitenanschlagkörpers 111. Thus, by means of the screw 151, the eccentric wheel and finally also the front end stop body 146 are braced with the body of the cutting tool 111.
