Abstract

An apparatus for removing a waste portion from a blow molded article is disclosed. The apparatus removes the waste portion while the article is enclosed within the blow mold and features a gripping structure for gripping the waste portion and a power assembly associated with the gripping structure to move the gripping structure from the article, thereby pulling the waste portion from its point of attachment with the article. The gripping structure includes two opposed gripping means which are arcuately movable about their respective pivot points. Each pivot point is laterally displaced from the gripping structure and positioned along a line extending through the shortest distance from the pivot point to that portion of the gripping structure which is closest to the attachment of the waste portion to the article.
