ABSTRACT:
An assembly and method for turning an article traveling on a conveyor. The assembly includes a conveyor having an upstream end and a downstream end, and first, second and third turning stations spaced apart from each other and disposed adjacent the path of a conveyor, with each station including a sensor for sensing an oncoming article and a selectively activatable surface, disposed downstream of said sensor, for turning an article 90 degrees. A computer selectively activates each of the surfaces responsive to information received from the sensors to thereby selectively turn an article either 90, 180 or 270 degrees total as desired.
