Abstract
A trimmer apparatus (10) comprising dual moveable belts (64) and (90) for removing a dome scrap (12) from a hollow, blow molded plastic bottle (14), is described. The dual belts are supported on spaced apart pulley systems (20) and (22) forming a linear path (24) along which the bottle travels. The distance between the pulley system is adjustable for different size bottles. A groove (12A) on the dome scrap is engaged by the belts which are rotating in a similar direction. However, one belt is moving somewhat faster than the other. This provides for moving the bottle linearly along the path, while spinning the bottle. As the bottle spins past a knife blade (112) the dome scrap cut from the bottle.
