  • the tamping feet 52a used as roller tools 16a together with the exchangeable holders 22a, in particular the tillage area 74a of the same not covered by the tamping feet 52a result in an assembly effective in their entirety as a tamping foot.
  • circumferential sides 56a 'and 58a of a respective padfoot 52a may be made to continue the circumferential sides 56a, 58a of a changeable holder 22a, for example with a similar curved profiling or angled orientation relative to one another. Accordingly, axial sides 60a 'and 62a' can continue the axial sides 60a and 62a of the tool holder 22a.
  • such a pad foot 52a has a holder shank 26a which, similarly as in FIG Fig. 6 is indicated, extending from the respective pad foot 52a down and the holder opening 24a in the change holder 82a can be arranged passing through. It can by a example, also in Fig. 26 recognizable locking member 102a again a locking action against detachment of the padfoot 52a can be achieved.
  • the padfoot 52a on the exchangeable carrier 22a In order to prevent a rotation of the padfoot 52a on the exchangeable carrier 22a, it is designed such that it can enter into a rotation-preventing positive engagement with the various supporting surfaces formed on the supporting region 72a, in particular the second and third supporting surfaces 82a, 84a.
  • the padfoot 52a is in its four corner regions, ie each in the transition region between one of the peripheral sides 56a ', 58a' to one of the axial sides 60a 'and 62a', extending in the direction of the holder shaft 26a extending second Jacobabstütz Schemeen 106a trained. These are shaped to have complementary surface areas to the inclined second support surfaces 82a, which surfaces in their entirety rest on the second support surfaces 82a.
  • a corresponding mutual abutment interaction could also be achieved with third counter-support portions 108a formed in the axial sides 60a 'and 62a' of the padfoot 52a between respective second counter-support portions 106a in cooperation with the third support surfaces 84a. Also in the circumferential sides 56a 'and 58a' formed between two second Jacobabstütz Schemeen 106a fourth Jacobabstweil Schemeen 110a could be achieved or supported by cooperation with the fourth support surfaces 86a on the change holder 22a such rotation preventing positive engagement interaction become.
  • the Fig. 26 illustrates the variability of the above-described changeover assembly 20a with respect to the applicability of various roll tools 16a. Illustrated by way of example are three different bits 18a, which can be coupled with the change holder 22a as required. Also shown are four different pad feet 52a, which are constructed to be identical to each other, in particular for rotation prevention on the change holder 22a, with the support portion 72a of the change holder 22a in the region of their respective counter-form-fit engagement formation 107a. All of these different roller tools 16a can be mounted on a compressor roller 10a to which the above-described changeover holders 22a are fixed. Here, of course, any combinations of different roller tools 16a are possible.
  • the Fig. 27 illustrates the procedure when attaching a roller tool 16a, so for example bit 16a or padfoot 52a, to a change holder 22a.
  • the respectively to be mounted roller tool 16a is inserted with its holder shaft 26a in the provided on the change holder 22a holder opening 24a and so far inserted into this example by hammer blows until the locking member formed as a locking member 102a engages in the associated Arretierorganfactö réelle in the change holder 22a.
  • the final assembly condition is in Fig. 27 shown lower right. In this state, the chisel head 46a rests on the first support surface 80a of the changeable holder 22a with its first counter-support region 97a projecting radially beyond the holder shank 26a.
  • the locking member 102a engages with the aligned locking member receiving openings 98a, 100a.
  • the Fig. 28 illustrates the procedure for dismantling a roller tool 26a, so for example, chisel 18a or padfoot 52a, from the changeover holder 22a.
  • a roller tool 26a so for example, chisel 18a or padfoot 52a
  • Fig. 27 recognizable right below, stands in the assembled state of the holder shaft 26a in the Komhalterinnenraum 92a out.
  • This state can be used, for example, by means of a crowbar 112a or a similarly curved tool laterally engage the change holder interior 92a, thereby under the holder shaft 26a and tilting by releasing the locking state Arrestor 102a in the provided on the change holder 22a first Arretierorganisö Anlagen 98a the roll tool 16a, here, for example, chisel 18a, at least so far out of the opening 24a, that by additional engagement with the part of the roller tool 16a lying outside of the chisel holder 22a, it can be completely pulled out of the opening 24a.
  • a sliding wedge 114a may be used which is inserted laterally into the interchangeable holder interior 92a and, supported on the outer peripheral surface 14a of the roll mantle 12a by wedging action, displaces the holder shank 26a in the opening 24a, again so far that the arresting member 102a retards its Ratchet action gives up.
  • the sliding wedge 114a can be driven by hammer blows in the exchange holder interior 92a. In this case, relatively large forces can be generated, which can cancel the locking action of the locking member 102a.
  • roller tool 16 is additionally to be secured by an anti-rotation member against rotation on the changeover holder 22a, of course, before the displacement of the holder shank 26a of this anti-rotation member from this receiving opening 104a in the holder shaft 26a are pushed out, thus a displacement of the holder shaft 26a in the direction of Longitudinal axis L 2 , to allow.
  • roller tools in particular also differently shaped chisels or differently shaped stamping feet, can be provided on the outer circumference of a compressor roller or can also be fixed in other patterns.
  • the positioning of rolling tools by means of the change-holder arrangements to be provided according to the invention does not necessarily have to take place directly on the outer circumferential surface of the roll shell. It is also possible, for example, to provide an unstructured, smooth roll shell and to surround it with an example of a multi-part shell-like enclosure, on which then the bit holders are fixed and the various roll tools can be attached.
