ABSTRACT OF THE DISCLOSURE The apparatus comprises a pair of rotatable devices each holding a plurality of metal shaping and/or cutting rollers, the rollers of one device meshing with rollers of the other device to produce specific designs or widths of material. This is made possible by merely selecting suitable rollers of both sets and when production of a specific metallic section of desired widths are terminated, other rollers are selected by rotating the rotatable devices. When suitable rollers have been selected they are locked in operating position and when another design or widths are required, the devices are unlocked, a selection is made, and the devices are again locked to produce the new metallic section or widths of material.
