Abstract: A wound tube is made of profiled plastic strips, the profiling of which comprises at least the edge region. The edge region is designed such that edge regions of successive coils, the edge regions lying mutually adjacent during winding, can be connected in a form-fitting manner, and at least one of the surfaces of the plastic strips has ribs projecting perpendicularly essentially to one side in order to form a flat inner surface during winding. The tube wall of the wound tube is designed as a double wall and is assembled from a first inner plastic strip and from a second outer plastic strip, wherein the ribs projecting perpendicularly essentially to one side fix the distance of the outer plastic strip from the inner plastic strip. A device with which such wound tubes can be advantageously produced on-site is also provided.
