ABSTRACT:
An apparatus for balancing a body to correct for unbalance determined during a measurement run on a balancing machine. The body to be balanced is rotated at a measuring speed by compressed air and the unbalance is determined. A braking device then is applied to the body to brake the body and rotate the body at a low speed. When a predetermined portion of the body is located in a desired angular position, a stopping device, such as a pawl, is actuated to stop rotation of the body. Appropriate mass is then added to or removed from the body to correct the unbalance. If necessary, the pawl is released, and body is incrementally rotated so that unbalance can be corrected on several portions of the body. The apparatus, instead of balancing the body, is usable to mark the body as to the location of unbalance.
