DE102010011172A1 - Device for cutting open of food products, particularly high speed slicer, comprises product supply unit, which is formed to supply product to be cut along feed direction to cutting plane, in which cutting knife is moved - Google Patents

Abstract

The device comprises a product supply unit (11), which is formed to supply a product (17) to be cut along a feed direction (R) to a cutting plane (S), in which a cutting knife (19) moves, particularly in a rotating or revolving motion. The product supply unit is formed to supply the product along the feed direction during the air cut phase. An independent claim is also included for a method for cutting open of food products, particularly high speed slicer.

Description

The invention relates to a device for slicing food products, in particular high-performance slicer, with a product feed, at least one cutting blade which rotates about a knife axis and / or planetary about a central axis and the at least one product to be cut in a product feed direction can be fed, and one Adjusting device for the cutting blade, with which the cutting blade between a cutting position and an additional function position is movable.

Such devices are basically known and serve to slice food products such as sausage, meat and cheese at high speed. Typical cutting speeds are between several hundred to several thousand cuts per minute. Modern high-performance slicers differ, inter alia, in the design of the cutting blade and in the manner of the rotary drive for the cutting blade. So-called sickle or spiral blades rotate about a rotation axis, also referred to here as a knife axis, wherein this rotation axis itself does not carry out any additional movement. For slicers with circular knives, on the other hand, it is provided that the rotating circular knife is also circulated in a planetary manner around a further axis spaced apart from the axis of rotation (also referred to here as center axis). Which blade type or type of drive is to be preferred depends on the respective application. In general, it can be said that higher cutting speeds can be achieved with only rotating sickle knives, whereas rotating and additionally planetary rotating circular knives can be used more universally without sacrificing cutting quality.

The above-mentioned high cutting speeds make it necessary - and this applies regardless of the type of knife and the type of drive - that in certain operating situations, in particular in a portionwise slicing of products, so-called idle cuts are performed in which the knife continues to move, d. H. performs his cutting motion, but not in the product, but "in the void" cuts, so temporarily no slices are separated from the product and these "cutting breaks" can be used to a formed with the previously separated slices portion, such as a stack of discs or shingles arranged discs to be transported away. The time passing between two consecutively separated slices does not suffice for a proper cutting performance or cutting speed for a proper removal of the slice portions. The length of these "cutting breaks" and the number of idle cuts per "cutting break" depend on the particular application.

A problem known in practice in connection with the performance of blanks is that, in most cases, it is not enough to simply stop the supply of the product temporarily to prevent the separation of slices. In fact, in the case of products with a soft consistency, it regularly happens that relaxation effects occur after the product feed has stopped, as a result of which the front end of the product passes beyond the cutting plane and thus into the effective range of the cutting blade. The result is an undesirable separation of so-called product snippets or product chips. Apart from this, such a chopping formation inevitably occurs regardless of the product consistency whenever the products are continuously fed during the slicing operation, that is, when the products are cut. H. even with products with a firm consistency, in which therefore do not occur the above-mentioned relaxation effects, it comes with a continuous product supply to a Schnitzelbildung.

The phenomena described above are well known to the person skilled in the art, which is why this will not be discussed in detail.

Measures are already known from the prior art, which serve to avoid a Schnitzelbildung when performing blanks. For this example, on EP 0 289 765 A1 . DE 42 14 264 A1 . EP 1 046 476 A2 . DE 101 147 348 A1 . DE 154 952 . DE 10 2006 043 697 A1 and DE 103 33 661 A1 directed.

Accordingly, it has already been proposed not only to interrupt the product supply for the performance of blanks, but also to withdraw the product, if appropriate together with the product support. This approach reaches its limits, in particular, when the cutting speeds and / or the masses to be moved become too large, because then it can no longer be ensured that the front end of the product can be withdrawn sufficiently quickly. As an alternative to retracting the product, it has also been proposed to move the cutting blade away from the front end of the product. Both solutions have the consequence that between the front end of the product and the cutting blade a sufficiently large distance is produced, which reliably prevents a Schnitzelbildung. The required knife stroke is only a few millimeters, but must be done in a very short time in the order of a few hundredths of a second. The possibility of knife adjustment can also be used for additional functions be, for. B. for adjusting the cutting gap or for idle cuts in the context of a height adjustment or adjustment of the immersion depth of the cutting blade, which takes place in particular with respect to the or the aufzuschneidenden products or the product edition, which will be discussed in more detail below.

The prior art proposes various ways to produce the desired distance between knife and product by a displacement of the knife.

One way, for example, in DE 101 47 348 A1 is described, to move only the rotating knife holder on which the knife is interchangeably mounted and which is also referred to as a knife holder, knife shaft or rotor, relative to the other components of the so-called cutter head, in addition to the mentioned Knife holder in particular comprises a rotary bearing for the rotational movement of the knife or the knife holder and a base part, with which the cutter head and thus the knife holder is attached to a frame or frame of the slicer. This attachment can be done for example on or in a so-called cutting head housing, on or in which not only the cutter head and knife, but also the drive motor for the with the cutter head z. B. are mounted on a drive belt cooperating knife rotary drive.

It is also possible to displace the cutter head as a whole, so that a relative movement between knife holder and pivot bearing of the knife is not required for adjusting the knife. Such a solution is for example in DE 10 2006 043 697 A1 shown.

Furthermore, it is possible to move the entire cutterhead housing including cutter head and rotary drive. Solutions of this type are for example in EP 1 046 476 A2 described.

These approaches described above differ not only in terms of the size of the mass to be moved, but also in terms of design effort and applicability for different types of knives or drives. Although a movement of only the knife holder, for example, has the advantage of a relatively low mass to be moved, but means a relatively high design effort, since with the knife an object must be moved along an axis that simultaneously rotates at high speed about this axis. For this problems in connection with the storage of the knife or the knife holder to solve. While the above-mentioned sickle or spiral blades only rotate about one axis, but this axis does not additionally carry out a circulation movement, concepts for adjusting the blade despite the aforementioned storage problems can be realized with reasonable effort. This is different with slicers with rotating and at the same time planetary revolving circular knives, because here there is the problem to accomplish with reasonable design effort a displacement of only the knife or the knife holder.

The above statements also apply if - as basically z. B. for separating oval slices of products with a circular cross section known - which defined by the cutting edge of the knife cutting plane is not perpendicular to the product feed.

The object of the invention is, in particular to further improve a slicing with adjustable cutting blade of the type mentioned in that the knife adjustment in design terms is simple and reliable, and in particular in conjunction with the implementation of blank sections can be used.

The solution of this object is achieved by the features of claims 1, 24 and 26.

According to one aspect of the invention, the cutting blade is coupled at a first region with the adjusting device and at a second region with a guide, wherein the adjusting movement of the cutting blade is determined by an exciter movement of the adjusting device and by the guide. In this case, the adjusting device not only serves to generate the adjusting movement, but at the same time ensures that the adjusting movement and thus the movement of the cutting blade in space are determined. The adjusting and the guide, which attack in particular different areas of the cutting blade, so together can form a positive guide for the cutting blade and set in this way its movement in the room clearly. Therefore, it is not necessary according to the invention, in addition to at least two whatsoever guides or holders of the cutting blade to provide the adjusting device as a third device which engages a third portion of the cutting blade to set the cutting blade only in motion, while the determination of the Adjustment only by the two or more guides or brackets. Therefore, according to the invention, the adjustment of the cutting blade can be realized in a particularly simple manner in terms of design.

In one embodiment of the invention it is provided that the adjustment movement of the cutting blade is a pivoting or tilting movement or comprises a pivoting or tilting movement. The adjustment of the cutting blade can so, but does not have to be a pure pivoting or tilting movement. In particular, the adjusting movement may be a superposition of two individual movements, one of which is predetermined by the guide and the other by the adjusting device.

The guide for the cutting blade may include a pivot bearing. Preferably, the guide comprises at least one link and / or lever, in particular at least one pair of links and / or levers, which are respectively hinged on the one hand to the cutting blade and on the other hand to a base. Both bases are in particular a cutting head housing. It is particularly provided that the articulation is located at the base on the articulation on the cutting blade.

In a preferred embodiment, the adjusting device comprises an eccentric drive. Alternatively, the adjusting device may comprise a linear drive, which is in particular a spindle drive or a cylinder-piston arrangement.

In a possible embodiment of the invention, the cutting blade is pivotally suspended on the second region and kept deflectable at the first region.

The adjusting device and / or the guide can be coupled to a rotary bearing for a drive shaft.

The drive shaft may be part of a drive unit which is adjustable and thereby causes the adjustment of the cutting blade. The drive unit in turn can be part of a knife head comprising the cutting blade. Alternatively, the drive unit can carry a knife head, which is a sickle cutter head for a sickle knife rotating about the knife axis, or a circular knife head for a circular knife rotating around the knife axis and rotating around the central axis planetary. The adjustable drive unit can thus be universally used for different types of cutter heads.

In general, therefore, according to the invention it can be provided that for adjusting the cutting blade a cutting blade, a knife holder to which the cutting blade is interchangeably attachable, and / or a drive unit carrying a cutter head is adjustable.

In a particular embodiment of the invention, the drive unit comprises a drive shaft and at least two spaced apart in the direction of the longitudinal axis of the drive shaft pivot bearing for the drive shaft. It can be provided that the one pivot bearing is coupled to the adjustment and the other pivot bearing with the guide. Independent protection is claimed for this principle, which will be discussed in more detail below.

According to one embodiment of the invention, a cutter head as a whole is adjustable by means of the adjusting device, wherein preferably the cutter head comprises a knife holder to which the cutting blade is exchangeably attachable, and at least one pivot bearing for the movement of the cutting blade about the knife axis and / or about the central axis. The knife head can again be a sickle cutter head for a sickle knife rotating about the knife axis or a circular knife head for a circular knife rotating around the knife axis and rotating around the central axis planetary.

Furthermore, the invention proposes that a stationary frame is provided, wherein a cutter head as a whole or a knife holder to which the cutting blade is exchangeably attachable, relative to a frame-fixed carrier is adjustable. The carrier may be arranged on or in a cutting head housing. The carrier may also be the cutting head housing itself.

In a further particular embodiment of the invention, the adjustment of the cutting blade is designed such that in the additional function position of the cutting blade, the distance between the cutting blade and a reference plane which is parallel to a cutting edge defined by a cutting edge of the cutting blade cutting edge extending with increasing distance from a level defined by a product support of the product feeder increases. The cutting knife can be tilted forward as it were. This can take into account the fact that in a continuously advancing during cutting feed of the product in a manner known to those skilled in a projecting beyond the cutting plane, at least approximately wedge-shaped front product section is present without an adjustment of the cutting blade in an undesirable manner from the product would be disconnected if the product feed - for example, to carry out blank cuts - temporarily stopped. The adjustment movement of the cutting blade according to the invention can be adapted to this phenomenon in such a way that the cutting blade is pivoted or tilted in accordance with this wedge shape, ie the cutting blade is adjusted, as it is just necessary to avoid the formation of chips. Independent protection is claimed for this principle, which will be discussed in more detail below.

In this case, the adjusting movement of the cutting blade can be designed such that the cutting blade is at least approximately pivotable or tiltable about a, in particular imaginary, point which is located in a plane defined by the product support level or below.

A rotary drive associated with the cutting blade may be arranged fixed to the frame or capable of compensating movement adapted to the adjusting movement of the cutting blade.

The rotary drive can be arranged together with a cutter head on or in a frame-fixed cutting head housing.

Furthermore, it can be provided that the rotary drive cooperates with a knife head which carries out the adjusting movement as a whole or with a part of the knife head, in particular a knife holder, which carries out the adjusting movement, in particular via at least one drive belt.

As already mentioned above, it is provided according to a further independent aspect of the invention that the adjusting movement of the cutting blade is designed such that in the additional function position, the distance between the cutting blade and a reference plane parallel to a cutting blade located in the cutting position by a cutting edge defined cutting plane extends and in particular is located on the side of the cutting blade facing the product feed increases with increasing distance from a defined by a product support the product feed level.

Also already mentioned above, another independent aspect of the invention, according to which for adjusting the cutting blade, a drive unit for the cutting blade is adjustable, comprising a drive shaft and at least two spaced in the direction of the longitudinal axis of the drive shaft pivot bearing for the drive shaft, wherein the one pivot bearing with the Adjustment and the other pivot bearing is coupled to a guide.

The invention further relates to the use of the inventive devices for performing blanks, in particular the portioned slicing of food products, wherein for temporarily interrupting the separation of slices of the product, the cutting blade moves away from the front end product and after performing one or more idle cuts to resume the Separating slices of the product is moved back again.

In particular, the idle cuts are performed with stopped product feed.

In general, the term "additional function" is to be understood as meaning a function which does not exclusively relate to the actual slicing function, that is to say the rotational or rotary movement of the cutting blade. The additional function is, in particular, the performance of empty cuts when portionwise slicing the products. The additional function can also be a height adjustment or adjustment of the immersion depth of the cutting blade, in particular with respect to the product or products to be cut or the product support, more precisely the avoidance of chips during the height or immersion depth adjustment performed blank cuts. The adjustment movement of the knife is thus when needed when the additional function is to be performed, this additional function - depending on their nature - with rotating or rotating cutting blade and / or with a stationary cutting blade is feasible.

In a preferred embodiment of the invention is - as already mentioned - provided that the adjustment of the cutting blade is a pivoting or tilting movement or includes a pivoting or tilting movement. This has the advantage that the forces required for adjusting can be kept relatively low. Furthermore, it is advantageous that no sliding or sliding bearings are required, as they are required in a purely translational, for example axial, adjusting movement.

If the adjusting movement is designed such that the cutting blade is no longer aligned parallel to the given in the cutting position cutting plane in the additional function position with the cutting plane defined by the cutting blade, then this is irrelevant for the implementation of blank sections, as it depends on the orientation of the cutting blade with respect to the front end product basically does not arrive, as long as it is ensured that no chips are separated from the front end product by z. B. it is ensured that a sufficiently large distance between the cutting blade and the front product end is present.

The provision of a pivoting or tilting movement at least as part of the adjustment has the further advantage that in this way a desired distance between the cutting blade and the front end of the product can be made particularly quickly and also particularly simply.

The invention will now be described by way of example with reference to the drawings. Show it:

2a and 2 B a schematic side view ( 2 B shows an enlarged section of 2a ) of a slicer according to the invention with a tiltable cutting blade,

3a and 3b each schematically a side view of a possible concrete embodiment of a cutting head of a slicer according to the invention in a cutting position ( 3a ) and in a blank position ( 3b ), and

4a and 4b 1 is a schematic side view of another possible concrete embodiment of a cutting head of a slicer according to the invention in a cutting position (FIG. 4a ) and in a blank position ( 4b ).

1 shows a schematic side view of a known from the prior art high-performance slicer, which serves food products 27 such as meat, sausage, ham or cheese, sliced. During the cutting process lies the product 27 on a product pad 37 on and is by means of a product feeder 13 along a product feed F moves in the direction of a cutting plane S. The product feeding direction F is perpendicular to the cutting plane S. As mentioned in the introductory part, such slicers are also known in which the angle between the product feed direction and the cutting plane is different from 90 °. From the product feeder 13 are in 1 only the already mentioned product edition 37 as well as a so-called product holder 25 shown with claws or grippers in the rear end of the product 27 engages and can be driven by non-illustrated drive means in and against the product feed F, as indicated by the double arrow.

The cutting plane S is independent of the operating state of the cutting blade 11 always through the cutting edge of the cutting blade 11 Are defined. During the slicing operation, the cutting blade acts 11 with a cutting edge, also referred to as counter knife 31 Together, the front end of the product edition 37 forms. In practice, the cutting edge is usually a separate, replaceable component z. B. plastic or steel, which is not shown here for reasons of simplicity.

As mentioned in the introductory part, it can be at the cutting blade 11 to act as a so-called circular knife, which rotates around a central axis planetary as well as rotating around its own knife axis. Alternatively, it may be in the cutting blade 11 to act as a so-called sickle or spiral knife, which forms a non-circular knife disc with a cutting edge, z. B. has on a spiral path around the blade axis edge and does not rotate planetary, but only rotates about the blade axis A. In principle, other types of knives may also be provided. The drive for the cutting blade 11 is in 1 not shown.

To as part of an additional function of the slicer between the knife 11 and the front end of the product 27 To make a distance, an adjusting device, not shown, is provided which is adapted to the cutting blade 11 to move. As indicated by the double arrow in 1 indicated, it is known from the prior art to move the cutting blade parallel to its axis of rotation (knife axis) A. For this purpose, the cutting blade 11 be slidably mounted parallel to the axis of rotation A. In connection with the execution of blanks is with disengaged knife 11 (in 1 indicated by a dashed line), ie at spaced from the front product end knife 11 , a Schnitzel or Schnipselbildung safely avoided.

With a portionwise slicing of the product 27 as it is in 1 is shown, form the separated product slices 33 portions 35 , in the 1 are shown as a disk stack. Once a portion 35 is finished, this portion 35 transported away in one direction. Thus for the removal of the finished slice servings 35 Sufficient time is available until the beginning of the formation of the next serving 35 executed the mentioned blank cuts, including on the one hand the product feed referred to as product feed (here, the product holder 25 ) and on the other hand the cutting blade 11 by means of said adjusting in the in 1 dashed position shown is moved.

2a schematically shows a slicer according to the invention in a side view. The product feeder 13 is shown in the position in which the product 27 is cut open. For loading with a new product, the product feed 13 be pivoted in an at least approximately horizontal position. In the illustrated cutting position, however, the product feed 13 and thus the product feed direction F is inclined relative to the horizontal H, namely by an angle α, which is for example about 40 °. Since in this embodiment, the product feed F and thus by the product support 37 Defined plane E is parallel to the knife axis A (but what - as already mentioned above - is not mandatory), here is the inclination angle α between the horizontal H and the plane E of the product support 37 located. However, the invention can also be used in conjunction with those slicers in which a product supplied in a horizontal or vertical direction is cut open.

In the illustrated embodiment, the product support 37 an inclined plane for the product 27 dar. The feed movement of the product 27 is thereby supported by gravity. Of greater importance, however, is that due to the skew of the product feeder 13 the front end of the product is not oriented vertically, as would be the case with a horizontally lying product, so that, due to the inclination of the front end of the product, the deposit of the separated product slices 33 - here on a conveyor belt 45 - improved or even a usable product storage is possible.

While in slicers known from the prior art, the cutting blade 11 - as shown in 1 - Is moved parallel to the knife axis A, for example, to carry out blank cuts a distance between the cutting blade 11 and front product end are according to the invention - like 2 B using two examples shows - Adjustments of the cutting blade 11 provided, in which the orientation of the cutting blade 11 and thus the orientation of the through the cutting edge of the cutting blade 11 defined cutting plane S in the room changed.

In 2 B is the cutting position of the knife with solid lines 11 in which the cutting plane S and one through the cutting edge 31 defined reference plane coincide, which is a simplification here, as in practice between the cutting blade 11 and the cutting edge 31 a small, usually adjustable cutting gap is present, which need not be discussed here in detail. Dashed lines according to one embodiment, an additional function position is indicated, in which the cutting blade 11 - here as part of the knife head 19 - Has experienced an adjustment, starting from the cutting position, which comprises - based on the drawing view - taking place in a clockwise direction pivoting or tilting movement. According to another, indicated by dash-dotted lines embodiment, the pivoting or tilting movement of the cutting blade is counterclockwise.

The invention thus enables - depending on the specific embodiment - adjusting movements of the cutting blade or a cutting blade comprising the cutter head both in the one and in the opposite pivoting or tilting. In particular, the invention provides that not only the knife 11 or a knife holder alone, but here only schematically indicated cutter head 19 is adjusted as a whole. This will be described below in connection with the 3a and 3b or the 4a and 4b discussed in more detail. The adjusting movement of the knife 11 or the cutterhead 19 ultimately takes place relative to a fixed frame or frame 23 the Slicer. This will be discussed in more detail below in connection with the mentioned figures.

The 3a and 3b show a possible concrete embodiment of the invention. At the knife head 19 it is a sickle cutter head, ie the cutting blade 11 is a sickle blade, which performs a self-rotating movement about a knife axis A and does not rotate in addition planetary.

The knife 11 is interchangeable on a here so designated knife holder 17 attached, which is also referred to as a blade holder, rotor or blade shaft.

The knife head adjustable here as a whole in the manner described in more detail below 19 further includes a drive shaft 65 in a front pivot 21 and in a rear pivot 20 is rotatably mounted. The rotary drive of the drive shaft 65 takes place by means of a motor forming the rotary drive 39 that has a drive belt 43 with a pulley 71 cooperates, non-rotatably on the drive shaft 65 is appropriate. The motor 39 is stuck with a wall 47 connected, which is part of a cutting head housing 41 is, which with respect to the adjustment movement of the cutter head 19 on a fixed frame or frame 23 (see. 2a and 2 B ) is attached. An adjustability of the cutting head housing 41 as a whole in directions that are in through the cutting edge of the knife 11 defined cutting plane S lie, relative to the product support (of which only the level E defined by them is shown here) are also possible for the object of the invention, but otherwise not significant.

A cover or hood with the cutterhead housing 41 is connected and while cutting operation, the cutting blade 11 at least partially surrounds, is also provided, but not shown here.

The knife head 19 is in the front area by means of a guide 61 forming lever pair 63 on the cutting head housing 41 hinged suspended. The pivot points 73 the lever 63 on the cutting head housing 41 lie above and behind the articulation points 75 the lever 63 on the knife head 19 , This suspension of the cutterhead 19 via its front pivot bearing 21 ,

At a rear area, namely at the rear pivot bearing 20 , is the knife head 19 from an adjusting device 15 held so that for adjusting the cutter head 19 and thus the cutting blade 11 relative to the cutterhead housing 41 that the drive shaft 65 rotatably mounted pivot bearing 20 by an exciter movement of the adjusting device 15 is deflectable. This excitation movement is generated by a respect to the cutting head housing 41 stationary, rotatably driven shaft 67 rotatably with an eccentric 69 connected, located in a corresponding receptacle of the pivot bearing 20 can turn.

The suspension or holder of the cutter head 19 is designed in this embodiment such that a by rotating the shaft 67 generated rotational movement of the eccentric 69 90 ° counterclockwise (as in 3b indicated by the arrow) an adjusting movement V of the cutter head 19 and thus the cutting blade 11 causes a clockwise pivoting or tilting movement. By the exciting movement of the adjustment 15 becomes the pivot bearing 20 - and thus the knife head 19 in its rear area - moved forwards and downwards. In cooperation with the front of the lever 63 provided pivoting suspension results in the mentioned adjustment movement, which has the consequence that the orientation of the through the cutting edge of the cutting blade 11 defined cutting plane S with respect to the cutting head housing 41 and thus with respect to the front end of the product 27 changed.

The extent of this tilting of the cutting blade 11 is relatively small. To illustrate this movement is therefore again on the in 2 B dashed knife head shown 19 directed.

The embodiment of 4a and 4b is different from that of the 3a and 3b in particular by another front pivoting suspension of the cutter head 19 and an opposite rotational movement of the rear pivot bearing 20 over the eccentric 69 interacting wave 67 the adjustment 15 ,

The pivot points 73 and 75 the lever 63 lie at least approximately in a plane parallel to the cutting plane S of the knife 11 in the in 4a shown cutting position runs. The suspension and mounting of the knife head 19 in this embodiment are chosen such that the taking place here in a clockwise direction of rotation of the eccentric 69 by 90 ° has the consequence that the rear pivot bearing 20 of the knife head 19 with respect to the cutterhead housing 41 moved forward and up. This will be the cutterhead 19 and thus the cutting knife 11 tilted forward. In the blank position according to 4b thus takes the distance between the cutting blade 11 and the original, in the cutting position according to 4a given position of the cutting plane S with increasing distance from the plane defined by the product edition level E. The location of the articulation points 73 and 75 alone is not decisive for the "direction of rotation" of the tilting movement of the cutting blade 11 but merely a parameter of several parameters, the overall direction and extent of the tilting movement of the cutting blade 11 establish.

The extent of this tilting of the cutting blade 11 is again comparatively small, so that to illustrate this movement on the in 2 B dot-dashed knife head 19 is referenced.

By appropriate design of the suspension and mounting of the cutter head 19 This adjustment can be designed such that the cutting blade 11 at least approximately pivoted or tilted about a virtual point lying in the plane defined by the product support E or below.

The knife head 19 including the adjustment 15 may alternatively be designed such that the cutter head 19 including adjustment 15 completely within the cutterhead housing 41 lies.

Furthermore, according to the invention, additional measures that have not been mentioned so far can be provided for the deflection or elongation of the drive belt 43 when adjusting the cutter head 19 and thus the directly from the drive belt 43 rotationally driven pulley 71 occurs, at least partially compensate. One measure for this, for example, consist in adjusting the cutter head 19 also the rotary drive motor 39 in on the adjustment movement of the cutter head 19 coordinated way to move so that at least up to a To some degree, the effects of the cutterhead adjustment on the drive belt 43 be compensated.

The effect of the belt elongation or deflection can also by a suitable orientation of the cutter head, which of those in the 3a and 3b or in the 4a and 4b deviates, at least largely eliminated.
