Abstract
The roller has, in the centre, a finish-rolling rib which corresponds to the flank angle, the core radius, the pitch-circle radius and the rib height of the thread to be produced. Pre-rolling ribs with decreasing rib height are arranged symmetrically towards the two ends. The core radius on the pre-rolling ribs increases progressively at the ends of the roller (R3 > R2 > R1) and the flank angle decreases progressively ( alpha 3 < alpha 2 < alpha 1). Relative to the pitch-circle radius of the finish-rolling rib, the pitch-circle radius (2, 3) of each pre-rolling rib is selected to be progressively greater than an amount (z1, z2) such that the distance (y1, y2), measured from the cutting point of the flank of an inner rolling rib with its associated pitch circle, at right angles to the corresponding flank of the next rolling rib arranged towards the rolling end, is essentially equal to the difference (x1, x2) between the rib heights of neighbouring rolling ribs. This roller makes it possible to give a grinding wheel such a profile that said wheel can grind taps by longitudinal feed, industrially, from both sides. <IMAGE>
