Abstract: An object imaging assembly includes a source of individual objects which move along a predetermined course of travel; an image capture device having a line of sight which extends across the course of travel; and an electromagnetic radiation emitter which emits electromagnetic radiation in a beam which extends transversely across the predetermined course of travel and the line of sight.

Abstract: A method and apparatus for sorting a gas-driven stream of generally flat and light-weight articles of varying dimensions execute a, preferably optical, inspection and upon so finding a non-conforming article remove the latter from the stream. In particular, the inspection and the sorting are executed during a substantially straight movement of the articles. The removing is executed through gas driving in a direction substantially transverse to the straight movement. Advantageously, the inspection is preceded by orienting the articles through a centrifugal force that orients said articles against an inclined wall in a transition to the vertical movement. Also airflow means (83,84) can be used to confine the articles in a thin layer.
