scientists sometimes refer to as conveyor belt theory

Developing the theory

Dietz and Hess were among the small handful who really understood the broad implications of sea floor spreading. If the Earth's crust was expanding along the oceanic ridges, Hess reasoned, it must be shrinking elsewhere. He suggested that new oceanic crust continuously spread away from the ridges in a conveyor belt-like motion.

Conveyors Article about Conveyors by The Free Dictionary

Belt conveyors with rough-top belts make possible inclines up to 28; cleated belts are limited on degree of incline only by the position of the center of gravity of the conveyed item. Live-roller conveyors move objects over series of rollers by the application of power to all or some of the rollers.

Screw Conveyor an overview ScienceDirect Topics

The screw conveyor is composed of a pipe with a welded steel strip that is formed into a continuous helix. The helix is referred to as the flighting. The distance along the pipe from one point on the flighting to the next similar point is called the "pitch". Couplings and shafts refer to the mechanisms by which two screw conveyors are joined.

Helix delta-T version 6 has a powerful capability to design conveyors which are curved in the horizontal and vertical plane.. A picture of a horizontally curve conveyor is shown below note the idlers are tilted up on the inside of the curve in order to prevent the belt from straightening and falling off the conveyor.
