ABSTRACT:
The belt grinding assembly according to the present invention includes (1) a frame (2) a belt grinding mechanism comprising a continuous abrasive belt having a backing with front and rear surfaces, and abrasive granules attached along the front surface; a mechanism for driving the abrasive belt in a first direction along a path relative to the frame; (3) a backup having a support surface for the belt along the path; which support surface is straight in the first direction and has a uniform shape corresponding to the shape of the edge surface in a direction at a right angle to the first direction; (4) a wheel having a periphery, a wheel axis at a right angle to the first direction; a mechanism mounting the wheel on the frame for rotation about the wheel axis; drive mechanism for rotating the periphery of the wheel past a loading station relative to the frame, and then past the support surface at a generally uniform rate of speed and in a first rotational direction; and (5) a plurality of pivoting engagement mechanisms for releasably engaging and holding a wrench during a grinding process.
