Device for bending jacketed tubes on tube-bending machines

摘要

Device for bending jacketed tubes on tube-bending machines, which comprises a bending mandrel and a hollow bending mandrel. By means of this device, it is possible to handle jacketed tubes like individual tubes when bending, without the necessity to fill the annular cross-section between the inner tube and the outer tube of the jacketed tube with sand beforehand. <IMAGE>
