Abstract
Apparatus having a let-down tube for dust free gravity transfer of bulk solids between upper and lower containers. A spool engageable with a discharge opening on the upper container has a lower end for slidably receiving an end of the let-down tube, the other end of which falls into the lower container. As solids flow from the upper to the lower container through the tube, the tube is progressively drawn up over the lower end of the spool, then longitudinally cut into sheets which are separately rolled up. The let-down tube permits transfer of the solids without demixing or aeration.
