A system that receives nanomaterials, forms nanofibrous materials therefrom and collects these nanofibrous materials for subsequent applications. The system is , coupled to a chamber that generates nanomaterials typically carbon nanotubes, produced from chemical vapor deposition and includes a mechanism for spinning the , nanotubes into yarns or tows. Alternatively the system includes a mechanism , for forming non-woven sheets from the nanotubes. The system also includes components , for collecting the formed nanofibrous materials. Methods for forming and collecting , the nanofibrous materials are also provided.
