Abstract
Cutting apparatus having spaced apart cutters which can be brought closer together are disposed on one end of a boom which is movable in a plane transverse to the longitudinal axis of a closely packed tube bundle to cut out short segments from the tubes starting at the periphery and working through the tube bundle by bringing the cutters closer together to provide clearance as the cutters move deeper into the tube bundle.
