<p>In the case of the cutting of a line in a quantity of sheet type work material where the cutting is interrupted before the line is completely cut, with the cutting tool being removed from the material at the point of interruption and later brought back into cutting engagement with the material at that point, complete and clean cutting along the desired line of cut is assured despite the interruption by ending the first cut which ends at the interruption point so that is continues slightly beyond that point along an end path and by starting the second cut along a start path which starts behind the interruption point so that the end path and start path overlap one another along a region of the desired line and by crossing each of the end and start paths with a line of cut to assure complete separation from one another of the portions of the material located on opposite sides of the desired line.</p> |
