<p>PROBLEM TO BE SOLVED: To prevent positional shift of molds and a lead and to form a plate layer, which is soft and even easily ground but is not peeled off, on a lead surface, by horizontally moving a first mold to a lead base side in a state where the first mold and a second mold hold a floating end of the lead between them, and at the same time, projecting the first mold toward the second mold side. SOLUTION: First and second molds 13 and 14 hold the tip end of a lead 3 between them, and in this status, the first mold 13 is moved to a lower pad 8 side and at the same time raised. The movement as the combination of horizontal movement and elevation may be a linear movement, however, preferably, the movement may trace a circular arc which does not loosen the lead or if loosens, minimize the looseness. The lead 3 begins to bend at a portion held by pads 8 and 12 and a portion held by the first and second molds 13 and 14. The deforming portions of the lead 3 do not cause positional shifts relative to the molds. As the intermediate portion of the lead does not come in contact with the molds, the plate layer covering the lead 3 is not peeled off.</p> |
