ABSTRACT:
A method for reshaping objects such as plastic bottles to re-establish round conditions after damage whereinin line bottles are conveyed along a path of travel between opposing, parallel, planar surfaces which are spaced a distance equal to the diameter of the objects. One of the surfaces is a span of an endless belt which is caused to travel in the direction of bottle travel at a speed which will cause the bottles to rotate as they are moved along the path. Rotation of the bottles while opposed lines of contact are maintained between surfaces of the bottle and the opposed planar surfaces re-establishes the objects to round configurations.
