A trimming apparatus (10) for removing the dome scrap (152) from a blow, molded bottle (150) is described. The apparatus includes an advancement wheel (12) and a rotation wheel (14) mounted on opposite sides of a path (16) formed by upper guide rails (18 and 20), lower guide rails (22 and 24) and the wheels. A knife assembly (62) is adjustably mounted beneath the advancement wheel and includes a knife blade (64) which extends into the path slightly in front of the area tangent to the wheels. The wheels are connected to drive motors (26 and 28). In use, the bottle is fed into the path such that the upper guide rails engage each side of the groove (152A) of the dome scrap. As the bottle moves into the apparatus, the advancement wheel engages the groove to move the bottle into the path between the wheels. When the bottle reaches the area of the path tangent to the wheels, the rotation wheel contacts the groove. The wheels are rotating in the same direction such that the wheels contact opposite sides of the groove in different directions thus, acting together to rotate the bottle. As the bottle rotates, the knife blade contacts the notch (150A) of the bottle and severs the dome scrap.

A trimmer apparatus for removing a dome scrap from a blow molded, plastic container, which comprises: (a) a frame defining a path through the apparatus; (b) conveying means for rotating the container consisting essentially of a single pair of opposed circular drive wheels positioned along the path on opposite sides of the path in a common plane, wherein each of the drive wheels is connected to a drive means mounted on the frame for rotating the drive wheels in the same directions and wherein the drive wheels acting together contacts the dome scrap and provides for rotating the container about a longitudinal axis of the container wherein one of the wheels acts to move the container and dome scrap along the path; (c) a cutting means mounted adjacent at least one of the drive wheels with a cutting edge of the cutting means projecting into the path adjacent the longitudinal axis, away from the drive wheel to provide for cutting the dome scrap from the container as the container is rotated on the longitudinal axis in the path between the drive wheels so that the container falls away from the path; and (d) a guide means mounted adjacent the other one of the drive wheels for keeping the dome scrap in contact with the one of the drive wheels for moving the container and dome scrap along the path and for moving the dome scrap out of the path and along the other drive wheel after the dome scrap is removed.
