ABSTRACT:
In a method and apparatus for trimming flash from blow molded articles with a rotating blade as they traverse a path of travel between a fixed guide and a rotary drive wheel, improvements are provided which include a mounting for the blade eccentrically offset from the axis of the drive wheel which allows the articles to be firmly supported by the guide and drive wheel before cutting commences, thereby improving the quality of the cut from the standpoint of reducing variability in planarity and in vertical position with respect to adjacent portions of the usable part of the article.
