In situ grinding apparatus for resurfacing rubber belts and rollers

An apparatus for resurfacing a rotating elastomer substrate, said apparatus comprising:

• a grinding wheel motor;
• a fixed motor mount wherein said motor mount is located proximal to the rotating elastomer substrate being resurfaced and wherein said motor mount comprises a rail system;
• a moveable base wherein said grinding wheel motor is secured to the moveable base;
• wherein said moveable base is in communication with said motor mount;
• said moveable base moves linearly across said rail system;
• wherein said moveable base slides towards and away from the rotating elastomer substrate by repositioning of projections from the motor mount in apertures formed in said moveable base;
• and
• a grinding wheel attached to a driveshaft of the grinding wheel motor, said grinding wheel in direct contact with said rotating elastomer substrate, wherein movement of the base changes a distance between the motorized grinding wheel and the rotating elastomer substrate so as to control amount of elastomer substrate that is removed;
• wherein rate of rotation of said grinding wheel is controlled by a high precision system which in turn controls a pattern impressed on the elastomer substrate;
• wherein the resurfaced elastomer substrate features uniform scale pattern.
