Abstract
Spotting instrumentalities for turning containers traveling along a predetermined path on a conveyor comprising, at opposite sides of the conveyor, a pair of drive rolls and a pair of idler rolls, said pairs of rolls being movable linearly along said path and, while being so moved, rotatable about axes parallel to the vertical axis of the container, said drive rolls being driven in rotation to rotate the container and said idler rolls being freely rotatable and a positioning dog operable by engagement with the positioning element on the side of the container to stop rotation of the container at a predetermined position of orientation. The drive rolls are provided with traction elements adapted to slip when rotation of the container is stopped by the positioning element and the idler rolls are provided with guide elements adapted to be displaced laterally by out-of-round containers and/or irregularities in the surfaces of the containers.
