    This can be tracked without great effort, the cutting element 8 when it is worn and / or re-ground and no longer sufficiently protruding from the Halterungsvor * direction 1 - the efficiency of a chipper, for which the holder device 1 according to the invention is intended, yes last but not least assuming that the cutting element 8 moves along a well-defined path. a circular arc) and thus interacts optimally with the other cutting elements of the chipper.
    This adjustment in the longitudinal direction now takes place according to the first variant in that at least one insert element 20 is arranged in the holding element (ie in the holding jaw 14) between the holding element and the rear end 2B of the second clamping element 6.
    The insert element 20 may be executed dabet any, for example, plate-shaped metal or plastic; it serves to move the second föemmelement 6 and thus the cutting edge 7 of the cutting element 8 in the longitudinal direction. Accordingly, the insert element 20 can be configured as desired in its thickness - two or more insert elements 20 can also be provided (not shown in the figures). To move only the clamping screw 11 has to be loosened a bit to loosen the clamping of the clamping elements 5, 6 - thanks to the execution of the first opening 12 as a slot then a shift in the longitudinal direction is possible.
    In the first variant of the invention thus holding jaws 14 and insert element (e) 20 act as adjusting. See the already mentioned exploded perspective Dartdastlung the first variant in Fig. 4.
    This first variant can also be carried out by instead of attaching the insert elements 20, the holding jaws 14 are exchanged for holding jaws, which are dimensioned the same as a Haitebacken insert element combination. This means that the holding jaws 14 are "thicker". are executed, wherein thicker here means a greater extent in the direction of the longitudinal axis 22 of the first Klenunelements 5 - by the thicker version, the cutting element 7 is also tracked in the direction of the longitudinal axis 22 and is again in optimal cutting position. For this embodiment, therefore, no insertion element 20 are necessary, however, the holding jaws 14 by "thicker". Holding jaws 14 replaced. 25/11/2011 14:11

    For tracking the cutting element 8 in the longitudinal direction or to compensate for the resulting by regrinding shortening a cutting element 8 can further be arranged at least one intermediate piece 27 behind the cutting element 8 - the intermediate piece 27 advantageously has a smaller thickness than the height 19 of the recess 17 or as the cutting element 8 and has, for example, a rectangular or square cross-section. Conveniently, it extends over the entire width of the recess 17. The "width " denotes in this case the extent of the (inserted) intermediate piece 27 in the direction normal to the longitudinal extent of the clamping elements 5.6.
    The fact that the thickness of the intermediate piece 27 is less than the height 19 of the recess 17 and the cutting element 8 ensures that the clamping elements 5, 6 rest over the entire surface of the cutting element 8 and thereby the full clamping force for holding the cutting element 8 is present.
    The intermediate piece 27 is inserted on the rear side of the cutting element 8 facing away from the cutting edge 7, as shown in FIG. 5. It can also be provided several intermediate pieces 27 of different dimensions. In this way, the cutting element 8 can be brought into an optimal cutting position in addition to the above-mentioned variants.
    According to a variant of the invention, which is shown in Fig. 4 represents the intermediate piece 27 may have at its in the mounted state of the back of the cutting element 8 side facing at least a first connecting element, which together with at least one running in the back of the cutting element 8 second connecting element -wjrkt. The connecting elements may be pin elements 29 and / or pin openings 30.
    For example, in the illustrated variant, the intermediate piece 27 has, as first connecting elements, two projecting pin elements 29 which interact in a known manner with corresponding pin openings 30 (second connecting elements) in the cutting element 8; Variants are also possible where both pin openings and pin elements are provided in intermediate piece 27 and cutting element 8. 25/11/2011 14:12

    Before installing the cutting element 8 intermediate piece 27 and cutting element 8 can be connected and then installed quickly and easily. It comes thereby to no twisting or slipping of the intermediate piece 27 during installation.
    Of course, the pin members 29 may be arranged in the cutting element 8 and the pin openings 30 in the intermediate piece 27 - this variant is not shown in the figures It should be noted that a variant with adapter without connecting elements is possible, however, not shown in the figures is.
    A second variant of the invention is shown in Figures 5 to 8 - Fig. 5 shows again a plan view, wherein the same elements are provided as in Fig. 2. However, here includes the adjusting device in addition to the holding jaws 14 and two adjusting screws 21, in the longitudinal direction the Klenunelemente 5.6, ie parallel to a longitudinal axis 22 of the clamping elements 5.6 run. The adjusting screws 21 are guided, for example, in threaded holes (not visible in the figures) in the holding jaws 14 or in a support jaw 31 arranged in the holding jaws and can thus be adjusted. The adjusting screws 21 then run al90 in the support bar 31, wherein the support bar 31 is again held in the holding jaws 14. Other solutions are possible. Of course, the number of setscrews 21 can be chosen differently, e.g. only one screw 21 or more than two can be provided.
    Fig. 6 shows a vertical section along the line B-B, which coincides again with the longitudinal axis 22 of the clamping elements 5.6 and is therefore designated by their reference numerals. The adjusting screws 21 are in contact with the rear end 28 of the second clamping element 6 - with slight loosening of the clamping screw 11, which holds the Kiemmelemente 5.6, can be moved by adjusting the screws 21, the second clamping element 6 in the longitudinal direction.
    Thus, therefore, the cutting element 8 can be tracked - a new cutting element 8 is installed, the adjusting screws 21 are accordingly rrtckstellt again, so that the second clamping element 6 is in a starting position. 25/11/2011 14:12

    Fig. 7 shows an exploded perspective view of the second variant of the support device according to the invention, while Fig. 8 shows a perspective view in the assembled state.
    In principle, combinations of the two variants are conceivable in which insert elements 20 and set screws 21 are combined in the holding jaws 14. For example, an insert element 20 may be designed as a support bar 31 through which the set screws 21 are guided. However, such a variant is not shown in the figures, but the illustration in FIGS. 7 and 8 approaches this variant.

    For easier installation and removal of the clamping elements 5,6, in particular the first-mounted clamping element (here the first clamping element 5), we recommend the use of a mechanical or hydraulic installation aid, which is positioned between the edge discs 3, 4 and pushes them apart. As a result, the clamping elements 5,6 can be easier to install or remove.
    11 shows a perspective view, in which the first 5 and the second clamping element 6 are already mounted substantially - only the clamping screw 11 is still inserted, being inserted through the first opening 12 designed as a slot and in the second opening 13 (FIG. not visible in Fig. 11), which is designed as a threaded hole is held. The pulley 26 (2.8 of the company Nord-Lock®), which is to prevent the self-loosening of the screw 11 during the operation on passing vibrations, can be seen.
    From the front, a cutting element 8 is inserted into the recess 17 (not visible in FIG. 11); which is clamped as soon as the two clamping elements 5,6 are connected by the clamping screw 11.
