  • Magnetic drive spiral conveyor system
    Patent number: 4981208
    Abstract: A spiral conveyor system utilizing an endless flat belt is disclosed. The belt travels in an endless path which includes a spiral portion. The belt is primarily driven in the spiral portion by a frictional engagement between the belt and a rotating driving element. The frictional engagement results from a combination of a tension induced in the belt by a secondary drive and a magnetic force between the rotating driving element and the belt.
