Abstract
PURPOSE: To enable casting of long rule and border rule of high precision by continuous fusion-bonding, by providing a small notch in the side of rule face or border rule face of leads joint surface to form a leads casting chamber, and enabling division and dispersion of shrinkage of the welded joint part.
CONSTITUTION: In long-length casting of rule lead or border rule lead 1', a notch part 4b is provided in a middle plate 2', amd molten metal is charged in a leads casting chamber 3', to bond with a joint face 4' of a lead n'. A protrusion 4c produced as a result of notch 4b divides and disperses the shrinkage, so that the shrinkage step difference affecting the rule face 8' is almost completely eliminated. Accordingly, shrinkage step difference and fin caused in continuous fusion-bonded part 4d in the conventional method are eliminated, and the effects thereof are shifted to a tail side 9', thus enabling production of rule leads or border rule leads of high precision capable of making extremely beautiful printing.
