ABSTRACT:
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.
