Abstract

A treatment article (1) for rotational surface treatment of an object, such as an object of e.g. stone, wood, linoleum, concrete, terrazzo and the like, includes a pad (2) having major surfaces (3, 4) facing away from each other and a plurality of flaps (6) connected to one (3) of the major surfaces of the pad. The flaps cover the pad and overlap each other in the circumferential direction of the pad (2). Also, the flaps (6) are each attached to a support layer (5) interposed between the pad (2) and the flaps (6).

Claims

1. Treatment article (1) for rotational surface treatment of an object, such as an object of e.g. stone, wood, linoleum, concrete, terrazzo and the like, comprising a pad (2) having major surfaces (3, 4) facing away from each other and a plurality of flaps (6) on one (3) of said major surfaces of the pad, which flaps at least partly cover the pad, a rotation axis (20) being defined perpendicular with respect to the major surfaces (3, 4), characterized in that the flaps (6) overlap each other at least in the circumferential direction of the pad (2) and are each attached to a support layer (5) interposed between the pad (2) and the flaps (6).

2. Treatment article (1) according to claim 1, wherein each flap (6) at one end (8) is positioned underneath a preceding flap (6′

) and at the opposite end (9) is positioned above a following flap (6″

), when seen in circumferential direction (roof tile fashion).

3. Treatment article (1) according to claim 1, wherein each flap (6) has a treatment surface facing (15) away from the pad (2).

4. Treatment article (1) according to claim 1, wherein flaps (6) are arranged according to a series (7) which is at least partly circular and concentric with respect to the rotation axis (20), and/or wherein flaps (6) are arranged according to series (7′

) comprising groups (22) of flaps which are spiral shaped with respect to the rotation axis (20).

5. Treatment article (1) according to claim 1, wherein flaps (6) are arranged according to an intermittent series (7″

, 7′

″

) comprising groups (21) of flaps which are formed according to a part of a circle concentric with respect to the rotation axis (19), which are equidistant to the rotation axis and which are at a distance from each other in circumferential direction.

6. Treatment article (1) according to claim 1, wherein the major surface (3) of the pad (2) onto which the flaps (6) are connected, has a central portion (11) which is free from flaps (6).

7. Treatment article (1) according to claim 1, wherein the flaps (6) comprise abrasive particles, such as particles of diamond, cubic boron nitride, aluminium oxide, silicon carbide, zirconium or any other abrasive substance or polishing compound.

8. Treatment article (1) according to claim 1, wherein the pad (2) comprises a lofty material, e.g. a nonwoven three dimensional web of fibers which are bonded to one another at points of mutual contact, and/or wherein the pad is of an expanded PVC material

9. Treatment article (1) according to claim 1, wherein the support layer (5) comprises a textile layer (16), a resin layer (17) and a thin glue layer (23) and wherein the textile layer (16) is adhered to the resin layer (17) through said thin glue layer (23).

10. Treatment article (1) according to claim 9, wherein the support layer (5) is at least partly covered with a glue layer (10), one edge (8) of each flap (6) being embedded in said glue layer (10) and being adhered to the textile layer (16) of the support layer (5) by said glue layer (10).

11. Treatment article according to claim 1, wherein the support layer (5) is adhered to the pad (2) through a thin glue layer (24).

12. Treatment article according to claim 1, wherein the tensile stiffness of the support layer (5) is higher than the tensile stiffness of the pad (2).

13. Floor treatment machine (13) comprising a frame, at least one rotary drive head (12), drive means for driving the rotary drive head in rotation about the axis thereof, handling means (14) for controlling and steering the machine over a floor (15) to be treated as well as a treatment article (1) according to claim 1 for rotational surface treatment of an object, such as an object of e.g. stone, wood, linoleum and the like, comprising a pad (2) having major surfaces (3, 4) facing away from each other and a plurality of flaps (6) on one of said major surfaces of the pad (2) and which at least partly cover the pad, characterized in that the flaps (6) overlap each other in the circumferential direction of the pad (2) and are each attached to a support layer (5) interposed between the pad (2) and the pate members (6) and in that the other major surface (4) of the pad (6) is supported against the rotary drive head (12).

14. Method for operating the floor treatment device (13) according to claim 13, wherein treatment article (1) is in contact with a floor and said treatment article with the associated rotary drive head (12) are rotated at a rotational speed of at least 175 rpm, preferably at least 800 rpm.

15. Method according to claim 14, wherein the rotational speed is in the range of 175-2000 rpm.

16. Treatment article (1) according to claim 2, wherein each flap (6) has a treatment surface facing (15) away from the pad (2).
