Belt conveyor, The working principle and characteristics ...

The belt conveyor is a conveyor belt that is supported by upper and lower rollers as a bearing member and a traction member. It bypasses the head and tail rollers to form a closed-loop conveyor. It transmits power by means of the friction between the driving roller and the conveyor belt.

US4505382A - Belt conveyor - Google Patents

The present invention relates to a belt conveyor, wherein the belt comprises two lateral beads which grip around the traction and suspension cables. The assembly is tensioned between two drums. The beads engage in grooves in one drum and in corresponding grooves in the other. Thus, around these drums, the cable and the beads of the belt are compressed together to ensure excellent drive, but ...
