Abstract (en)

[origin: EP0248983A1] For the transverse rolling of a profiled workpiece (10), for example a gearwheel, rolling jaws (1, 2) are movably mounted on tool carriers (5, 6). Both tool carriers (5, 6) are mounted jointly on two crankshafts (18, 19) on mutually offset crank pins (20, 21, 22, 23) and are driven to perform synchronous movements in opposite directions. Separately from this, the rolling jaws (1, 2) are driven to perform tangential rolling movements. <IMAGE>
