the blank 8 can commence in this case the blank 8 is drawn downwards via the drawing ring 9 the die lower part 3 is displaced downwards owing to the contour of the die upper part 2 and the design of the drawing ring 9 after the drawing operation there is produced a raw piece 10 which serves as a basic form for the subsequent operation of forming by rolling fig2 shows a position during the operation of forming by rolling it shows the rolling unit 7 with the upper bearing shell 11 and the lower bearing shell 12 the two bearing shell halves 11 12 serve to accommodate or mount the profiling rollers 13 these profiling rollers 13 are arranged in a distributed manner on the circumference of the rolling unit 7 the raw piece 10 is now taken past the profiling rollers by the vertical downward movement of the ram 4 with the die upper part 2 and thereby acquires on the outer diameter the longitudinal groove profile resulting from the arrangement of the profiling rollers a lubricating connection 14 can be seen at the outer edge of the tool 1 according to the invention via this lubricating connection 14 and via the lubricating line 15 lubricant is forced between the bearing shell halves 11 12 and the profiling.
