FIELD: transportation.

SUBSTANCE: belt conveyor with tubular cut of belt includes wrapped conveyor belt hung on drive and deflecting drums with upstream edges. Guide rollers are installed in the gap between edges of damping track of the belt. Clamping rollers for closing edges of the belt are mounted around its surface in diameter: D=(B+ℓ)/π, where B – width of the belt; ℓ is the width of fill piece. Fill piece is made of material with various stress-related characteristics of interacting elements: gripper and protrusion fixed on the opposite edges of the belt. Gripper is made in form of semi-closed shape, embracing the protrusion, made in form of rod shape. Pair of guide rollers for opening edges of the belt in front of drive drum is installed after clamping rollers to rotate in opposite directions when the said elements are touched.

EFFECT: reduction of power inputs, manufacturability and reliability of conveyor construction are ensured.
