ABSTRACT:
A method of and means for cutting hose of the type designed for use in high pressure hydraulic systems is disclosed in which the impingement of a high power laser beam is moved about the periphery of the hose in a plurality of passes. An embodiment is described in which the hose remains stationary with the beam being moved thereabout and a further embodiment is disclosed in which the beam remains stationary and the hose is rotated about its own axis. The provision of inert gas to prevent combustion both inside and outside the hose during cutting thereof is disclosed.
