Abstract
In a bulk material handling apparatus especially adapted for handling granular material a pair of flexible belts are arranged about drive and idler pulleys to provide a material receiving run of one belt, a substantially vertical run or section where the belts are in face-to-face contact for receiving and transporting the material therebetween, and an upper material delivery run where the material is discharged at a different level. In the change of elevation section, staggered rollers are provided to urge the edges of the belts into engagement with one another so as to substantially eliminate leakage or spillage of material from therebetween. The edges of the belts are stretched in following a sinuous path between the edge rollers thereby causing the confronting belt edges to firmly engage one another.
