ABSTRACT:
An alignment apparatus for aligning a selected object with respect to a top-dead-center portion of a cylindrical roll includes a support base that is adapted to mount on a peripheral, circumferential surface of the roll and over the top-dead-center portion thereof. A level indicator mechanism mounted on the base indicates the orientation of the base. An outer frame is pivotably mounted on the base to pivot about an outer gimbal axis. An inner frame is pivotably mounted in the outer frame and adapted to rotate about an inner gimbal axis. The inner gimbal axis is oriented substantially perpendicular to the outer gimbal axis. A positioning plate moveably mounts within the inner frame and is adapted to move along a reference plane defined by the inner frame. A follower mechanism connects to the positioning plate to align the positioning plate with a selected portion of the selected object, and a reference mechanism indicates the relative alignment of the positioning plate with respect to the top-dead-center of the cylindrical roll.
