Description

[0044] Exemplary embodiments of abrasive mops according to the invention are illustrated in a schematically simplified manner and are described in more detail in the following description.

[0045] FIG. 1 shows a side view of an abrasive mop in a first embodiment;

[0046] FIG. 2 shows a front view of the abrasive mop of FIG. 1;

[0047] FIG. 3 shows a cross-sectional view of the abrasive mop of FIG. 1 along cutting plane in FIG. 1;

[0048] FIG. 4 shows a front view of an abrasive mop segment of the abrasive mop of FIG. 1;

[0049] FIG. 5 shows a front view of a centering element of the abrasive mop of FIG. 1; and

[0050] FIG. 6 shows a side view of an abrasive mop as intended by an alternative embodiment.

[0051] FIGS. 1, 2 and 3 show a first embodiment of an abrasive mop 2. The abrasive mop 2 comprises two annular abrasive mop segments 4 and 6, which are slid onto a carrier element 8, which is formed by a tube piece, in such a manner that they abut against one another in the direction of an axis 24 of abrasive mop 2 (referred to as “abrasive-mop axial direction” in the following).

[0052] A ring-like centering element 12, which radially positions and centers abrasive mop segments 4 and 6 with respect to carrier element 8, is disposed between both abrasive mop segments 4 and 6. Abrasive mop 2 comprises a fixing element on each end in the form of an axial securing ring 18, which abuts against a corresponding abrasive mop segment 4 or 6. Axial securing ring 18 fixes and secures abrasive mop segments 4 and 6 and centering ring 12 on carrier element 8 against becoming displaced in the abrasive-mop axial direction.

[0053] Carrier element 8 is a tube having a central cutout 30 for being directly or indirectly connecting a drive shaft (not illustrated) of a tool or an abrasive machine. On the circumference side, carrier element 8 comprises a plurality of clearance holes 16. For fixing abrasive mop segments 4 and 6 on carrier element 8, a connective medium 10 is poured toward abrasive mop segments 4 and 6 through clearance holes 16 from central cutout 30 of carrier element 8 when producing abrasive mop 2. Connective medium 10 is a resin, in particular an epoxy resin. Connective medium 10 soaks a radially inner edge area of abrasive mop segments 4 and 6, which abuts against carrier element 8, and then hardens. Abrasive mop segments 4 and 6 are thus substance-bonded to carrier element and fixed thereto. Centering element 12 is also substance-bonded to carrier element 8 by means connective medium 10.

[0054] FIG. 4 shows a front view of abrasive mop segment 4. The embodiment of abrasive mop segment 6 corresponds to the embodiment of abrasive mop segment 4. Consequently, a description of abrasive mop segment 6 is not necessary.

[0055] Abrasive mop segment 4 is annular in shape and comprises axial abrasive lamellae 26, which each comprise a coated abrasive having abrasive grit disposed thereon or grit disposed thereon. Abrasive lamellae 26 are glued to each other in a connective area 34, which form an abrasive-mop-segment core. Connective area 34 is disposed on an end of abrasive lamellae 26, which extends inward in a radial direction. Abrasive mop segment 4 comprises a central cutout 36. An inner surface of abrasive mop segment 4, which defines central cutout 36, abuts against a circumferential surface of carrier element 8. Abrasive mop segment 4 comprises an annular groove 14 on each end.

[0056] As illustrated in FIG. 5, centering element 12 comprises an inner ring 20 and an outer ring 22. Inner ring 20 and outer ring 22 are connected to each other via at least three webs 32 or ribs, which extend radially. Outer ring 22 is disposed in ring grooves 14 of adjacent abrasive mop segments 4 and 6, ring grooves 14 being formed by cutouts of abrasive lamellae 26, and radially positions abrasive mop segments 4 and 6 with respect to centering element 12. Inner ring 20 abuts against carrier element 8 and radially positions centering element 12 with respect to carrier element 8. Thus, abrasive mop segments 4 and 6 are centered with regard to carrier element 8.

[0057] Axial securing rings 18 each have a radial collar 38 and a sleeve 40, which axially extends outward. The outer surface of radial collar 38 abuts against the inner surface of carrier element 8. Sleeve 40 abuts against a corresponding abrasive mop segment 4 or 6 on the ends. Sleeve 40 has a U-shaped end area 42, which corresponds to annular grooves 14. The U-shaped end area is disposed in a corresponding annular groove 14. This allows securing abrasive mop segments 4 and 6 and centering element 12 on carrier element 8 in the abrasive-mop axial direction.

[0058] In FIG. 6, another embodiment of an abrasive mop 46 is illustrated. Abrasive mop 46 corresponds to abrasive mop 2 illustrated in FIGS. 1 to 3, with the exception of the embodiment of the abrasive mop segments.

[0059] Abrasive mop 46 comprises three abrasive mop segments 48, 50 and 52. Both abrasive mop segments 48 and 50 are shorter in the abrasive-mop axial direction than abrasive mop segment 52. Both abrasive mop segments 48 and 52 have abrasive lamellae having the same grit, whereas abrasive mop segment 50 has abrasive lamellae having a differing grit than the grit mentioned above.

[0060] As noted above, it should be appreciated that various other modifications and variations to the preferred embodiments can be made within the spirit and scope of the invention. Therefore, the invention should not be limited to the described embodiments. To ascertain the full scope of the invention, the following claims should be referenced.
