    • The invention refers to a backing pad (30; 50; 60) for a power tool (1). The backing pad has an essentially platelike form and a trapezoid cross-section with a top surface (30a; 50a; 60a), a larger bottom surface (30b; 50b; 60b) and a slanting circumferential surface (17; 37) connecting the top and bottom surfaces. The backing pad can be connected to a tool shaft of the tool and is adapted for receiving a polishing or sanding material on the bottom surface. The backing pad is provided with essential recess (15; 34) and a plurality of holes (13; 35) and channels (16; 36) in order to create a predefined air flow between the bottom surface of the backing pad and a working surface. In order to increase efficiency of the dust extraction by means of the air flow it is suggested that the backing pad is provided with at least one additional hole (38) ending in an opening (38b) located in an annular outer section (39) of the bottom surface, the annular outer section (39) being located opposite to the slanting circumferential surface (17; 37) of the backing pad. The additional hole (38) is in connection with at least one opening (40a) located in the top surface of the backing pad.
    • 本发明涉及到背衬垫(30; 50; 60)一种用于动力工具(1)。 背衬垫具有基本上板状形状和梯形横截面的顶面(30A; 50A; 60A),较大的底面(30B; 50B; 60B)和一个倾斜周向表面(17; 37)连接顶 和底部表面。 背衬垫可连接到所述工具的工具轴,并且用于angepasst的底表面上接收的抛光或打磨材料。 背衬垫被提供有必要的凹部(15; 34),以便创建所述背衬垫的底表面之间的预定空气流量和一个工作表面和孔的多个(13; 35)和通道(36 16) , 为了通过空气的手段增加除尘的效率流,建议没有背衬垫被提供有位于在环形设计外部部分(39)的至少一个附加的孔(38)中的开口结束在(38B) 底表面,所述环形设计外部部分(39)被定位成与周向倾斜面(17; 37)的背衬垫。 所述附加孔(38)与位于所述背衬垫的顶表面的至少一个开口(40a)的连接。

    • The invention relates to a holding device (10a-i), in particular a grinding disc, for a grinding means (30a-i), which has at least one support member (12a-i) comprising at least one material opening (20a-i) which is provided for transverse transport of grinding dust to one side facing the grinding means (30a-i) in a plane parallel to a grinding surface (24a-i), and which has at least one securing layer (14a-i) for securing the grinding means (30a-i) on the at least one support member (12a-i). According to the invention when decoupled from the grinding means (30a-i) the at least one material opening (20a-i) is at least substantially open on a side facing the grinding means (30a-i) and on a side facing away from the grinding means (30a-i) is substantially delimited by the support member (12a-i).
    • 本发明涉及一种用于研磨装置(30a-i)的保持装置(10a-i),特别是研磨盘,其具有至少一个支撑构件(12a-i),该支撑构件包括至少一个材料开口(20a- i)设置用于在平行于磨削表面(24a-i)的平面中将研磨粉末横向输送到面向研磨装置(30a-i)的一侧,并且该研磨装置具有至少一个固定层(14a-i) 用于将所述研磨装置(30a-i)固定在所述至少一个支撑构件(12a-i)上。 根据本发明,当从研磨装置(30a-i)分离时,至少一个材料开口(20a-i)至少基本上在面向研磨装置(30a-i)的一侧上以及在远离 研磨装置(30a-i)基本上由支撑构件(12a-i)限定。
