ABSTRACT:
Products are transferred from a first conveyor to a second conveyor along a set feed path by a device including a pressurized pneumatic duct interposed substantially with no break in continuity between the outfeed end of the first conveyor and the infeed end of the second conveyor. The pneumatic duct is connected to a source of compressed air, which is admitted convergently with the feed direction and at a velocity and rate of flow such that the products are invested with movement by fluid power alone and caused thus to pass along the duct toward the infeed end of the second conveyor.
