Abstract: A method and apparatus for selectively directing work objects wherein the work objects are passed along a path of travel, predetermined characteristics of the work objects are sensed and work objects having the predetermined characteristics are diverted from the path of travel successively to alternate sides of the path of travel without movement in a return direction intermediate diversion of successive work objects.
Abstract: An apparatus for positioning work objects having a frame adopted to receive the work objects and to direct them along a course, a plurality of work members mounted on the frame in position for engagement by the work objects in the course, and a drive mechanism for rotating the work members while in engagement with the work objects to propel the work objects along the course and substantially into single file with the longitudinal axes thereof disposed in substantially coaxial alignment.
