WHITTINGTON SPIRAL DRUMS

WHITTINGTON Drums are normally mounted so that when in operation, they give the appearance that each spiral is moving towards the centre of the drum. Should the belt, through any outside influences, move to one side of the drum, the belt comes in contact with more spirals on that side. The resultant increase in forces moves the belt back to the centre of the drum where the forces are equal and opposite.
