Abstract:
A method of producing a double-sided belt structure from an endless body having a length, a first surface, a second surface, at least one load carrying cord embedded in the body with a lengthwise center and extending along the length of the body between the first and second surfaces of the body, and a thickness between the first and second surfaces of the body, the method comprising the steps of:moving the body in a controlled endless path around at least a first pulley with the second surface of the body outside of the first surface of the body;while the body is moving in the endless path, a) predetermining a center position of the center of the at least one load carrying cord between the first and second surfaces of the body, b) determining a grinding value for the first surface of the body based on the center position of the center of the at least one load carrying cord, and c) determining a grinding value for the second surface of the body based on the center position of the center of the at least one load carrying cord;grinding the second surface of the body based upon the determined grinding value for the second surface of the body; andgrinding the first surface of the body based upon the determined grinding value of the first surface of the body.
