NEW WHEELED CONVEYOR MOVES BAGS
A flexible conveyor system on wheels for loading and unloading freight cars carrying bagged and baled materials has
just been placed on the market. It speeds up the work, requires fewer men, and can be moved about to send the bags around corners or into the warehouse rooms. This one-man outfit is a new development of a screw conveyor system introduced some years ago. Sections of spiral tubes, revolved by an electric motor, have screwlike threads on the surface that keep the bag moving. The load moves at the rate of ninety feet a minute.
