Abstract
A tube supported on a rotating mandrel is cut by a pair of cutter blades spaced apart a distance corresponding substantially to the diameter of the mandrel and which are moved simultaneously in a direction toward the mandrel and transversely of its axis of rotation a distance sufficient to enable the cutters to engage the tube at circumferentially spaced zones and sever the wall of the tube. The cutters move along a path that is tangential, rather than radial, relative to the mandrel.
