Abstract
A transport system for conveying articles along conveyance paths including straight, curvilinear, horizontal, inclined and declined conveyance sections. The articles are conveyed between a pair of vertical belts while being supported by protrusions extending from the vertical belts. The vertical belts are guided using a multiplicity of vertical rollers that are configurable into straight, curvilinear and dynamically changing conveyance sections. Multiple conveyance sections can be joined end to end to transport articles over complex paths and over long distances. The articles conveyed may include semiconductor wafers.
