    • A method for making a nonwoven a abrasive article. A preferred aspect of the method comprises the steps of: a) providing a nonwoven web having a first side and a second side, the web comprising a plurality of fibers; b) frothing a liquid make coat precursor; c) applying the frothed make coat precursor to at least the first side of the web in such a manner so as to achieve a substantially uniform coating of the make coat precursor along the fibers of the web; d) spraying a plurality of fine abrasive particles onto the first side of the web, wherein the particles are sprayed so as to form a cloud of abrasive particles that deposit onto the fibers of the web in a substantially uniform distribution; and e) curing the make coat precursor to thereby form a hardened make coat which adheres the abrasive particles to the web and wherein the abrasive particles substantially protrude from the outer surface of the hardened make coat.

    • The present invention relates to an abrasive article for abrading material from a workpiece. In one embodiment, the abrasive article includes a back-up pad having first and second major surfaces. The first major surface includes a shaft adapted to connect the abrasive article to an abrading apparatus for movement relative thereto. Adjoining the second major surface are first and second resilient support portions, to which are attached first and second abrading members, respectively. When an operator applies a first force to the abrading apparatus, the first abrasive surface contacts and abrades the workpiece. When the operator applies a second force that is greater than the first force, both the first and the second abrasive surfaces contact and abrade the workpiece.
    • 本发明涉及一种用于从工件研磨材料的磨料制品。 在一个实施例中,磨料制品包括具有第一和第二主表面的支撑垫。 第一主表面包括适于将磨料制品连接到研磨装置以便相对于其运动的轴。 第二主表面相邻的是第一和第二弹性支撑部分,分别附接有第一和第二研磨部件。 当操作者向研磨装置施加第一力时,第一研磨面接触并磨损工件。 当操作者施加大于第一力的第二力时,第一和第二研磨表面都接触并磨蚀工件。
