Abstract
A conveyor apparatus is divided into a plurality of end-to-end arranged conveyor tracks to advance flat items, in an edgewise upstanding, face-to-face engaging orientation to an item processing machine situated downstream of the conveyor apparatus. Each conveyor track is separately driven and is associated with a sensor which detects the extent of inclination of the items on the respective conveyor track. The drive of any individual conveyor track is de-energized if the items situated thereon assume an orientation having a steepness of predetermined extent and if, at the same time, the item processing machine and the drives of all conveyor tracks situated downstream of the individual conveyor track are at a standstill. Further, the drive of any individual conveyor track is energized and maintained energized if the items situated thereon assume a steepness less than the predetermined extent, or if the drive of any of the downstream-situated conveyor tracks or the item processsing machine is energized or is in an energized state.
