It is not always the completesystem, but more frequently an installation of numerousshort lengths between machines, that makes the most eco-nomical layout. Where used as process conveyors in thisway, the gravity line may be set entirely level, and thepackage pushed from one machine to another. In connec-tion with haul-chains, moving continuously or intermit-tently, gravity rollers make a convenient work bench.
