A tube manufacturing system (10) is provided that is capable of manufacturingtube structures that are on the nanoscale and larger. The system provides for control as to the structure and atomic makeup of the feed sheet material (5) used and provides motive force to the sheet material (5) being used to continuously advance the sheet material through the various system components. Rollers (17 and 18) are used for cutting sheet material (5). The rollers (17 and 18) may have troughs to place a sufficient mechanical force on the sheet material. After the tube structures are formed, they may be used in providing a source material for manufacturing macroscopic objects thus increasing the level of performance and capabilities of such objects due to the engineered properties of the tube structures formed within this system (1) and method of manufacturing. Processes for manufacturing of nanotubes are also disclosed, as are nanotubes manufactured by the processes and system of the invention.
