Zusammenfassung:	PURPOSE:To improve durability of a tackiness preventing effect by performing knurling work of a metal column member in its peripheral surface and cutting a formed protruding part then performing a plating process in the periphery of the column member, in the case of manufacture for a roller or the like feeding a thin thickness rubber sheet to a punching machine. CONSTITUTION:Knurling work is performed of a column member 6 except its shaft part. Here a formed recessed part 2 is set in its depth H to about 0.4 to 1.55mm. Next the formed recessed part 2 cuts its protrusion part in the peripheral edge to be removed by cutting work with one part of the peripheral surface of the column member 6. Thus a sharp angular part 12 is formed in the peripheral edge of the recessed part 2. Here the recessed part 2 is set in its depth D to about 0.3mm. And the column member 6, applying to its peripheral surface electroplating, forms a plating layer 4. Thickness t2 of the plating layer is set to about 0.03 to 0.05mm. By this constitution, durability can be improved of a tackiness preventing effect.
