Abstract:
Apparatus for electric-discharge texturing of a round surface of a roll, comprising:a rotational support for rotatably supporting and rotating the roll about a central axis;a main slideway that extends parallel to the central axis;a carriage supported for movement along the main slideway and including an auxiliary slideway that extends transversely to the central axis;an electrode positioner housing mounted on the carriage by the auxiliary slideway for movement toward and away from the roll along an adjustment axis that extends radially from the central axis; anda bank of electrode positioners mounted on the housing in a plurality of axial rows along the central axis and in a plurality of generally circumferential columns along the central axis, the electrode positioners each being operable to support an electrode for movement along an associated feed axis toward and away from the roll to provide the proper positioning therebetween for the electric-discharge texturing, and the feed axes of the electrode positioners of the axial rows extending angularly with respect to each other in an outwardly diverging manner from the roll and being equally angularly spaced from each other as well as being symmetrically located on opposite sides of the adjustment axis.
