Surface treating device
A surface treating device includes an open lofty non-woven layer ( 1 ) and a woven layer ( 2 ). The non-woven layer and woven layer have facing sides ( 5, 6 ) which are adhered to each other. A plurality of abrasive segments ( 3 ) is adhered to the woven layer on the side ( 7 ) of the woven layer ( 2 ) which faces away from the non-woven layer ( 1 ). Thus, the abrasive segments are held in a stable manner so as to better withstand the frictional forces exerted thereon during service.
1. Surface treating device, comprising an open lofty non-woven layer ( 1 ) and a woven layer ( 2 ), said non-woven layer and woven layer having facing sides ( 5 , 6 ) which are adhered to each other, as well as a plurality abrasive segments ( 3 ) adhered to the woven layer on the side ( 7 ) of said woven layer ( 2 ) which faces away from the non-woven layer ( 1 ).
2. Surface treating device according to claim 1 , wherein the abrasive segments ( 3 ) comprise a plastic matrix material as well as abrasive particles dispersed in the plastic matrix material.
3. Surface treating device according to claim 2 , wherein the abrasive particles ( 3 ) comprise boron, cubic nitride or diamond.
4. Surface treating device according to claim 2 , wherein the plastic matrix material of the abrasive segments ( 3 ) is adhered to the woven material ( 2 ) by engagement of said plastic matrix material in the pores or voids between the weft and warp threads of the woven material.
5. Surface treating device according to claim 1 , wherein the woven layer ( 2 ) comprises high-strength fibers, such as Kevlar© fibers.
6. Surface treating device according to claim 1 comprising a circular circumference, wherein the abrasive segments ( 3 ) are regularly distributed in circumferential direction.
7. Surface treating device according to claim 1 , wherein said non-woven layer ( 1 ) has a mounting side ( 4 ) which faces away from the woven layer ( 2 ), for mounting onto a treatment tool, such as a polisher or grinder.
8. Surface treating device according to claim 7 , wherein the mounting side ( 4 ) of the non-woven layer ( 1 ) comprises fastening means, such hook and/or loop fastening means.
9. Surface treating device according to claim 1 , wherein the abrasive segments ( 3 ) are obtained by pouring a flowable mixture of plastic material and abrasive particles onto the woven layer ( 2 ) and subsequently curing said mixture.
10. Surface treating device according to claim 3 , wherein the plastic matrix material of the abrasive segments ( 3 ) is adhered to the woven material ( 2 ) by engagement of said plastic matrix material in the pores or voids between the weft and warp threads of the woven material.
11. Surface treating device according to claim 2 , wherein the woven layer ( 2 ) comprises high-strength fibers, such as Kevlar© fibers.
12. Surface treating device according to claim 2 comprising a circular circumference, wherein the abrasive segments ( 3 ) are regularly distributed in circumferential direction.
13. Surface treating device according to claim 2 , wherein said non-woven layer ( 1 ) has a mounting side ( 4 ) which faces away from the woven layer ( 2 ), for mounting onto a treatment tool, such as a polisher or grinder.
