To roll form a worksheet (32) by a turret punch press, at least one pair of coacting tools (34, 36) are mounted to the opposed turrets (46, 48) so that when those tools are rotated to the work location, they cou ld be driven to a predetermined relative distance towards each other to make contact with the workpiece (32). The depth of the formed shape is determined by the relative distance the coacting tools (34, 36) are driven towards each other. By moving the worksheet (32) at the same time that the coacting tools are making contact with the worksheet, roll forming of the worksheet is effected. By providing the coacting tools in the opposing indexing stations and synchronously rotating those stations, a complex pattern can be roll formed on a worksheet . |
