Abstract
A rolling mill coil-forming apparatus includes a rotating quill that supports an elongated path hollow structure, such as a laying head pipe, for receiving elongated material after it has been rolled. A portion or the entire elongated structure is formed from modular, selectively replaceable components. The fabricated modular structures facilitate formation of zones within the component, such as including by way of example wear-resistant zones, material transport guide structures and friction reducing zones.
