(13) FIG. 1A discloses a processing section 1, comprising a round disc-shaped base 2 with a processing side 3 and a mounting side 4 (cf. FIG. 2). As apparent from FIG. 1A and FIG. 2, the processing side 3 is arranged on the one side of the base body 2, and the mounting side 4 is arranged on the other side of the base body 2, opposed to the processing side 3. The mounting side 4 comprises a first mounting element 6. The mounting element 6 comprises a torsionally stiff first connection means 7, which is basically also constructed round disk-shaped and largely covers the mounting side 4, as shown in FIG. 2. In this embodiment, the first connection means 7 is a hook-and-loop means, which provides a torsionally stiff fastening.

(14) As shown in FIG. 1A, the processing side 3 is constructed as a closed processing surface 5. The processing surface 5 comprises grinding profiles 8, which extend from the processing side 3 in radial direction. In the embodiment shown in FIG. 1A, four centrally arranged octagonal grinding profiles 8 are provided, as well as four further polygonal grinding profiles 8 arranged at the circumference of the processing section 1.

(15) Another embodiment for a processing section 1 according to the invention is shown in FIG. 1B. This merely distinguishes from the embodiment shown in FIG. 1A in shape and arrangement of the grinding profiles 8. As shown in FIG. 1B, the grinding profiles 8 may also be round-cylindrical. The grinding profiles 8 may be formed as metal-bonded, diamond-bonded and/or plastic-bonded grinding profiles 8. Depending on which kind of floor processing is to be done, suited processing sections 1 will be selected and mounted onto an adapter system 10, as described in more detail as follows.

(16) In FIGS. 3 to 5 an adapter system 10 according to the invention is shown, wherein FIG. 3 shows the adapter system without second mounting elements 13, FIG. 4 shows the adapter system 10 with second mounting elements 13 mounted on the same, and FIG. 5 shows the adapter system 10 with processing sections 1 mounted on the same. As can be seen in the figures, the adapter system 10 is round disk-shaped.

(17) The adapter system 10 has a receiving side 11 with several receptacles 12 for receiving processing sections 1 (cf. FIG. 5). In the shown embodiment, the adapter system 10 comprises six receptacles 12 that are circularly arranged in regular intervals along the circumference U of the adapter system 10. As shown in FIG. 4, each one receptacle 12 comprises four second mounting elements 13. The mounting elements 13 are all equally configured, constructed as round cylinders and evenly arranged inside the receptacle 12.

(18) FIG. 6 shows cut free view of a second mounting element 13. The mounting element 13 comprises a torsionally stiff second connection means 14. The second connection means 14 extends substantially parallel to the receiving side 11 of the adapter system 10. In this embodiment, the second connection means 14 is a hook-and-loop means, which is complementary to the first connection means 6 being a hook-and-loop means as well. Other torsionally stiff connection means 6 and 14 may also be possible, for example in shape of a bayonet lock or the like.

(19) Furthermore, the second mounting element 13 comprises a spring unit 15. The spring unit 15 is a composite component, which comprises a metal part 16 and a plastic part 17. The metal part 16 is constructed round disk-shaped and arranged between the second connector 14 and the plastic part 17. In this embodiment, the plastic part 17 is a plastic foam component with certain elastic properties that define the suspension or damping properties of the spring unit 15, respectively.

(20) Moreover, the second mounting element 13 comprises a central through hole 20 for receiving a locking device (not shown in further detail). This way, the second mounting element 13 may be fixed at the receptacle 12 of the adapter system 10 via a corresponding locking means receptacle 21.

(21) The receptacles 12 of the adapter system 10 further comprise boundary walls 18. The boundary walls 18 extend from the receiving side 11 of the adapter system 10 in axial direction and form a substantially circular boundary of the receptacle 12. Further, the boundary walls 18 comprise two breakthroughs 19 per each receptacle 12. The breakthroughs 19 face radially outward and are arranged along the circumference U of the adapter system 10. The breakthroughs 19 serve for the insertion of a tool 100, as described in more detail in the following.

(22) The boundary walls 18 of the individual receptacles 12 are connected to each other with stiffening fins 22, which also extend from the receiving side 11 of the adapter system 10 in axial direction, and stabilize the adapter system 10 in itself. As for example shown in FIG. 3, the stiffening fins 22 are arranged radially star-shaped towards the inside. Further, in between the individual receptacles 12, in each case two arcuate shaped stiffening fins 22 running in the direction of the circumference U of the adapter system 10 are arranged.

(23) To mount a processing section 1 to the adapter system 10, the processing sections 1 are inserted into the respective receptacle 12 in axial direction until the first connection means 7 of the processing section 1 contacts the second connector means 14 of the receptacle 12 of the adapter system 10. The processing section 1 is then releaseably mounted in the receptacle 12 by slight pressure in axial direction. Since the first connection means 6 covers almost the entire mounting side 4 of the processing section 1 (cf. FIG. 2), the orientation of the processing section 1 in relation to the receptacle 12 is irrelevant.

(24) To remove a processing section 1 from a receptacle 12, the tool 100 shown in FIG. 7 is to be used. The tool 100 comprises a nose 101 and a lever shaft 102. The nose 101 is connected with the lever shaft 102 via a curved transition part 103. Furthermore, the nose 101 is constructed to be inserted into the receptacle 12 through a breakthrough 19 of a boundary wall 18 of a receptacle 12, as can be seen in FIG. 8. In this state, the nose 101 is arranged between the receiving side 11 of the adapter system 10 and the mounting side 4 of the processing section 1 in axial direction. The tool 100 tilts in the area of the rear edge of the nose 101 by moving the lever shaft 103 relative to the adapter system 10, so that the nose 101 is rearranged in the direction of the mounting side 4 of the processing section 1. The nose 101 contacts the mounting side 4 of the processing section 1 and pushes the processing section 1 out of the receptacle 12 in axial direction. Hereby, the connection between the first mounting element 6 of the processing section 1 and the four second mounting elements 13 of the receptacle 12 is released and the processing section 1 may be lifted off the adapter system 10.

(25) FIG. 9 discloses a second embodiment of the adapter system 10 according to the invention. The adapter system 10 shown in FIG. 9 distinguishes from the adapter system described before in that the receptacle 12 only comprises one second mounting element 13a. The second mounting element 13a shown in this figure is essentially equally constructed as the second mounting element 13 disclosed in FIG. 6, hence, comprising a spring unit 15 in form of a composite component. Since the second mounting element 13a almost completely occupies the receptacle, the second mounting element 13 has two notches 23 for receiving the nose 101 of the tool 100. The tool 100 is exemplarily shown in FIG. 9, wherein the nose 101 is received within one of the notches 23. It may be well observed that the nose 101 reaches through the breakthrough 19 and is arranged between the receiving side 11 of the adapter system and the processing side 4 of the processing section 1 (not shown).

(26) FIG. 10 shows a floor-processing machine 200. The floor-processing machine 200 is a floor-grinding machine and comprises an adaptor system 10 according to the invention with 6 attached processing sections 1 according to the invention. During operation of the floor-processing machine 200, the grinding profiles 8 of the processing surface 5 of the processing section 1 lie atop the floor surface to be processed. The drive shaft (not shown) of the floor-processing machine 200 puts the adapter system 10 with the torsionally stiff attached processing sections 1 in rotation, such that the floor surface is processed, in particular is grinded layer-wise by the grinding profiles 8. Due to the floating mount of the processing sections 1 created by the spring units 15, an optimum in processing result is achieved.
