ABSTRACT:
Apparatus and method for fluid jet cutting of a roll of material in situ, e.g. a multiplicate wound roll of material, by which a fluid jet nozzle and a roll of material are rotated relatively to each other about an axis with the roll of material in radially inwardly disposed relation to the nozzle while a fluid jet, e.g. liquid jet, exiting from the nozzle is directed at a selective axial point along the extent of the roll of material to cut circumferentially into and through the roll of material in situ and the spent fluid is concomitantly collected radially inwardly of the roll of material, preferably in an arrangement having fluid jet cutter means including such nozzle, support means including mandrel means, e.g. a stationary mandrel, for operatively rotationally supporting removably thereon the roll of material in a position along the axis in radially inwardly disposed relation to the nozzle for relative rotational movement between the roll of material and such nozzle and mandrel means, about the axis and further including rotational mounting means, e.g. a chuck drive, for mounting the roll of material for rotation about the axis and about the mandrel means, in such position, and fluid receiving means operatively disposed radially inwardly of the position of the roll of material, e.g. a trough selectively defined in the periphery of the mandrel, for collecting spent fluid, with the nozzle being selectively disposed in operatively flow aligned relation to the fluid receiving means at such axial point.
