Fluid jet cutting of rolls of material

Fluid jet cutter arrangement for cutting a roll of material in situ comprising

• liquid jet cutter means including a liquid jet nozzle,
• support means including a mandrel extending along a substantially horizontal axis for operatively rotationally supporting removably thereon a roll of material to be cut in situ in a position along the axis in radially inwardly disposed relation to the nozzle for relative rotational movement between the roll of material and the nozzle and mandrel about the axis upon rotationally driving such roll, and further including rotational mounting and drive means for mounting the roll of material for driven rotation about the axis and about the mandrel in said position, and
• a liquid receiving trough operatively disposed radially inwardly of the position of the roll of material and selectively defined in the periphery of the mandrel for collecting spent liquid,
• the nozzle being selectively disposed in operatively flow aligned relation to the trough at a point along the mandrel for causing a liquid jet exiting from the nozzle to cut circumferentially into and completely through the roll of material in situ at such point and be collected by the trough during rotation of the roll of material upon such rotational driving of such roll.
