ABSTRACT:
A rolling machine assembly for use in a press brake formed of an upper roll subassembly including an upper roll and an upper base and a lower roll subassembly including a pair of lower rolls and a lower base, the bases being detachably secured to the ram and bolster, respectively, of the press brake. Motors of the positive displacement type, fed from a flow divider, rotate the rolls to form a sheet of metal into desired curvature. The lower base has symmetrically located sockets for reception of the tines of a forklift truck so that when the upper roll is in nested position upon the lower rolls, and the securing means are disengaged, the subassemblies may be lifted out of the press brake as a unit by the forklift truck to free the press brake for other usage, and with the reverse procedure being effective for installation.
