Title: Intermittent perforator wheel

Abstract: An intermittent perforator wheel structure for providing a tearing edge in a workpiece sheet. The tearing edge is defined by a line of spaced elongated slits and a line of spaced short perforation slits offset from the line of elongated slits. The offset is made to be a small preselected amount. The offset may be preselected to assure that the torn portions of the sheet provided by the spaces between the short slits do not extend beyond the line of elongated slits whereby the edge of the sheet seen by a data processing machine, or the like, into which the sheet may be fed comprises a smooth edge with the torn portions being recessed within the straight smooth edge.
