ABSTRACT:
In tube-shearing apparatus of the kind employing relatively transversely moving apertured dies and an internal supporting mandrel, the mandrel comprises an elastomeric body which is compressed axially with the high force to expand it radially against the tube wall such as to form not merely an internal support but effectively a supporting shear blade inside the tube. This allows clean shearing also of tubes having internal protuberances such as welding seams.
