Method of removing an exposed cord on a power transmission belt, an apparatus for carrying out the method, and a power transmission belt made by practicing the method

In combination

• a) an endless power transmission belt having a length, inside and outside surfaces, and laterally spaced side surfaces,
• said belt further having a body with a cord embedded therein;
• and
• b) an apparatus for removing a portion of the cord that is exposed on the side surface of the power transmission belt, said apparatus comprising:
• a belt supporting structure on which the power transmission belt is trained and run in an endless path;
• means for grinding at least one side surface of the belt running on the belt supporting structure;
• means for sensing the presence of the cord exposed at the one side surface,
• said grinding means including a grinding wheel to grind the one side surface;
• and
• means for activating the grinding means in response to a signal from the sensing
• means upon the sensing means detecting the presence of the cord exposed at the one side surface,
• whereby the grinding means, sensing means, and activating means can be operated to sense and grind a cord exposed at the one side surface as the belt is continuously run on the belt supporting structure.

In combination:

• a) an endless power transmission belt having a length, inside and outside surfaces, and laterally spaced side surfaces,
• said belt further having a body with a cord embedded therein;
• and
• b) an apparatus for removing a portion of the cord that is exposed on a side surface of the power transmission belt, said apparatus comprising:
• a frame;
• a belt supporting structure on the frame including spaced first and second pulleys on which the endless power transmission belt is trained and run in an endless path;
• means on the frame for stabilizing the belt including first and second rollers between which the belt on said belt supporting structure passes;
• grinding means including first and second grinding wheels;
• and
• means for mounting the grinding wheels to the frame for movement one each towards and away from a side surface on the belt trained around the first and second pulleys to remove an exposed cord portion on the side surfaces of the belt trained around the first and second pulleys.
