What is a Sandwich Belt Conveyor?
A sandwich belt conveyor uses two conveyor belts, face-to-face, to gently but firmly contain the product being carried, hence making steep incline and even vertical-lift runs easily achievable.

DSI Snake Sandwich Conveyor Profiles
Snakes are available in widely ranging profiles of C and S-Shape. In any case, a long bottom belt approach is possible to the sandwich entrance, and discharge may be on the high incline or may be after the extension of the carrying belt beyond the mouth of the sandwich.
