ABSTRACT:
An apparatus is disclosed for controlling the movement of flat bottomed articles in a plurality of different directions relative to a supporting platform. The article is supported on a plurality of clusters of helical, freely rotatable rollers mounted on a plurality of shafts. Selected ones of the shafts, or groups of shafts, each lying in one of a plurality of zones, are selectively driven in a clockwise direction, a counterclockwise direction or are held in stationary. Selective control of the shafts enable the apparatus to move the article parallel to the longitudinal axis of the platform in two selected directions, perpendicular to the longitudinal axis in two selected directions; diagonally of the longitudinal axis in four selected directions, and either clock or counterclockwise about an axis normal to the flat bottom of the article.
