Abstract
There is disclosed an elongated abrasive blade for use on a rotary device and especially suited for removing material from a surface such as a floor. The blade is essentially rectangular in shape and comprises a multiplicity of abrading chips arranged in linear groupings on a working surface of the blade. The groupings are spaced from one another, and are aligned in rows generally parallel to the major axis of the blade.
Claims9
A blade for a rotary motion stripping tool for removing material from a surface, the blade comprising:
- a generally rectangular plate-like main body portion, one planar surface of which forms a substantially flat work surface;
- and
- means for mounting said main body portion on said stripping tool so that said main body portion rotates in the plane of its work surface;
- a multiplicity of abrading elements affixed to said work surface, said abrading elements being arranged on said work surface in spaced apart strips lying substantially parallel to each other and to the major axis of said blade, and oriented so as to be essentially perpendicular to the minor axis of said blade, the length of said strips along the major axis being substantially greater than the length of said strips along the minor axis, said strips being spaced apart both along the major and minor axes of said blade, the spaces between said strips being large enough to enable the material removed from the surface being treated to be guided into said spaces and away from the stripping tool along said substantially flat work surface of said main body portion during the stripping operation.
