ABSTRACT:
A conveyor apparatus includes two space guide members over an upwardly facing support surface which can slidably support an article to be conveyed, and a pushing assembly supported for horizontal movement about the surface and having a plurality of pushing fingers which can engage the article and slide it across the surface. The pushing assembly is designed to permit movement of the outermost pushing fingers between a downwardly projecting position and a horizontally projecting position spaced above the surface and the guide members. A mechanism responsive to movement of the guide members toward each other is provided to automatically move the outermost fingers of the pushing assembly from the downwardly projecting position to the horizontally projecting position.
