Abstract
Apparatus (10,10') for electric-discharge texturing of a round surface (12) of a roll (14) includes a bank of electrode positioners (32) mounted on a carriage supported housing (30) in axial rows (34) and circumferential columns (36) with the axial rows diverging from a central axis A of roll rotation and with the axial rows symmetrically located on opposite sides of an adjustment axis B along which the electrode positioners are moved by the housing. The adjustment axis B of the housing (30) is inclined upwardly away from the central axis A. The electrode positioners (32) can be provided in an odd number or an even number of axial rows (34) and, in either case, the circumferential columns (36) of the electrode positioners (32) are slightly axially inclined along the central axis A.
