Abstract
A tube cutoff apparatus arranged to provide an improved cutoff of a tube avoiding dimpling of the tube. The apparatus includes an improved blade configuration and mechanism for moving the blade in different directions to effect a multistep tube cutoff. In a first step, the tube is chordally notched, and in a second step, the tube is diametrically sliced to provide a dimpleless cutoff.
